Hello, A new question has been asked in "Getting, Installing, and Upgrading MariaDB" by netzach. Please answer it at http://mariadb.com/kb/en/mariadb-on-sge-with-environmental-modules/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hi The title says it all. How do I setup MariaDB on a computer cluster using SGE and environmental modules with one shared place for the databases? I want the databases to be in /databases which is exported through a local network to the computational nodes. All computers run centos 7. Thank you Jonas Söderberg -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/mariadb-on-sge-with-environmental-modules/

[Maria-discuss] MariaDB Crashes due to Stored Procedure
by Joseph Onyilo 27 Sep '15

27 Sep '15

I created two Store procedures to time table scheduling some months back and test it at the time which was fine. The first procedure has a cursor to navigate a list of records and call the second procedure. The Second Procedure has two cursors for different scenarios. Now trying to a final test before moving to production and it crashes my MariaDB Server mid way. Even when I called the Second Procedure individually with static parameters, after three to five calls MariaDB still crashes. The Operating system is Centos 6.6, MariaDB 10.0.21 and error from log displays is as follows |This could be because you hit a bug.It isalso possible that this binary orone ofthe libraries it was linked against iscorrupt,improperly built,ormisconfigured.This error can also be caused bymalfunctioning hardware.Toreport this bug,see http://kb.askmonty.org/en/reporting-bugs We will try our best toscrape up someinfo that will hopefully help diagnose the problem,but since we have already crashed,something isdefinitely wrong andthis may fail.Server version:10.0.21-MariaDB key_buffer_size=134217728read_buffer_size=131072max_used_connections=3max_threads=153thread_count=2It ispossible that mysqld could useup tokey_buffer_size +(read_buffer_size +sort_buffer_size)*max_threads =467003K bytes ofmemory Hope that's ok;ifnot,decrease somevariables inthe equation.Thread pointer:0x0x7fdac266f008 Attempting backtrace.You can usethe followinginformation tofind out wheremysqld died.Ifyou see no messages after this,something went terribly wrong...stack_bottom =0x7fdad74cfd30thread_stack 0x48000/usr/sbin/mysqld(my_print_stacktrace+0x2b)[0xb7f84b]/usr/sbin/mysqld(handle_fatal_signal+0x398)[0x72b758]/lib64/libpthread.so.0(+0xf710)[0x7fdad710b710]/usr/sbin/mysqld(_ZN13st_select_lex17mark_as_dependentEP3THDPS_P4Item+0xa0)[0x5c8410]/usr/sbin/mysqld[0x73c544]/usr/sbin/mysqld(_ZN10Item_field15fix_outer_fieldEP3THDPP5FieldPP4Item+0x62f)[0x74c78f]/usr/sbin/mysqld(_ZN10Item_field10fix_fieldsEP3THDPP4Item+0x432)[0x74ce72]/usr/sbin/mysqld(_Z12setup_fieldsP3THDPP4ItemR4ListIS1_E17enum_mark_columnsPS5_b+0x163)[0x594a03]/usr/sbin/mysqld[0x6168f3]/usr/sbin/mysqld(_ZN18st_select_lex_unit7prepareEP3THDP13select_resultm+0x39c)[0x6648ac]/usr/sbin/mysqld(_Z21mysql_derived_prepareP3THDP3LEXP10TABLE_LIST+0x206)[0x5b4bc6]/usr/sbin/mysqld(_Z27mysql_handle_single_derivedP3LEXP10TABLE_LISTj+0x193)[0x5b5bd3]/usr/sbin/mysqld(_ZN13st_select_lex14handle_derivedEP3LEXj+0x47)[0x5ca857]/usr/sbin/mysqld(_ZN10TABLE_LIST14handle_derivedEP3LEXj+0x4f)[0x679f2f]/usr/sbin/mysqld(_Z28mysql_handle_list_of_derivedP3LEXP10TABLE_LISTj+0x3f)[0x5b5d4f]/usr/sbin/mysqld(_Z20mysql_prepare_insertP3THDP10TABLE_LISTP5TABLER4ListI4ItemEPS7_S8_S8_15enum_duplicatesPPS6_bbb+0xb8)[0x5c09a8]/usr/sbin/mysqld(_Z27mysql_insert_select_prepareP3THD+0x72)[0x5c0e62]/usr/sbin/mysqld(_Z21mysql_execute_commandP3THD+0x556f)[0x5d94bf]/usr/sbin/mysqld(_ZN13sp_instr_stmt9exec_coreEP3THDPj+0x1e)[0x81d26e]/usr/sbin/mysqld(_ZN13sp_lex_keeper23reset_lex_and_exec_coreEP3THDPjbP8sp_instr+0x8b)[0x82285b]/usr/sbin/mysqld(_ZN13sp_instr_stmt7executeEP3THDPj+0x155)[0x822d45]/usr/sbin/mysqld(_ZN7sp_head7executeEP3THDb+0x6c9)[0x820529]/usr/sbin/mysqld(_ZN7sp_head17execute_procedureEP3THDP4ListI4ItemE+0x5f6)[0x821796]/usr/sbin/mysqld(_Z21mysql_execute_commandP3THD+0x31f9)[0x5d7149]/usr/sbin/mysqld(_ZN13sp_instr_stmt9exec_coreEP3THDPj+0x1e)[0x81d26e]/usr/sbin/mysqld(_ZN13sp_lex_keeper23reset_lex_and_exec_coreEP3THDPjbP8sp_instr+0x8b)[0x82285b]/usr/sbin/mysqld(_ZN13sp_instr_stmt7executeEP3THDPj+0x155)[0x822d45]/usr/sbin/mysqld(_ZN7sp_head7executeEP3THDb+0x6c9)[0x820529]/usr/sbin/mysqld(_ZN7sp_head17execute_procedureEP3THDP4ListI4ItemE+0x5f6)[0x821796]/usr/sbin/mysqld(_Z21mysql_execute_commandP3THD+0x31f9)[0x5d7149]/usr/sbin/mysqld[0x5da9d7]/usr/sbin/mysqld(_Z16dispatch_command19enum_server_commandP3THDPcj+0x1d0d)[0x5dce4d]/usr/sbin/mysqld(_Z24do_handle_one_connectionP3THD+0x453)[0x69a2d3]/usr/sbin/mysqld(handle_one_connection+0x42)[0x69a3a2]/lib64/libpthread.so.0(+0x79d1)[0x7fdad71039d1]/lib64/libc.so.6(clone+0x6d)[0x7fdad581d8fd]Trying toget somevariables.Somepointers may be invalid andcause the dumptoabort.Query (0x7fdaa8818548):isan invalid pointer Connection ID (thread ID):3Status:NOT_KILLED Optimizer switch:index_merge=on,index_merge_union=on,index_merge_sort_union=on,index_merge_intersection=on,index_merge_sort_intersection=off,engine_condition_pushdown=off,index_condition_pushdown=on,derived_merge=on,derived_with_keys=on,firstmatch=on,loosescan=on,materialization=on,in_to_exists=on,semijoin=on,partial_match_rowid_merge=on,partial_match_table_scan=on,subquery_cache=on,mrr=off,mrr_cost_based=off,mrr_sort_keys=off,outer_join_with_cache=on,semijoin_with_cache=on,join_cache_incremental=on,join_cache_hashed=on,join_cache_bka=on,optimize_join_buffer_size=off,table_elimination=on,extended_keys=on,exists_to_in=onThe manual page at http://dev.mysql.com/doc/mysql/en/crashing.html containsinformation that should help you find out what iscausing the crash.| I also did a test on MariaDB 10.0.17 on windows still no luck.

[Maria-discuss] select using date_sub produces unwanted milliseconds in results
by Dan Ragle 26 Sep '15

26 Sep '15

We're converting from MySQL 5.1 to MariaDB 5.5.44 and I'm hoping someone can help clarify for me what's going on in the following scenario. In brief, we're getting milliseconds displayed in a particular date_sub calculation (and possibly other selects with date arithmetic, trying to figure out how to track them down is part of the goal of this post) where we aren't expecting them. MariaDB [testdb]> show variables like '%version%'; +-------------------------+---------------------+ | Variable_name | Value | +-------------------------+---------------------+ | innodb_version | 5.5.43-MariaDB-37.2 | | protocol_version | 10 | | slave_type_conversions | | | version | 5.5.44-MariaDB-log | | version_comment | MariaDB Server | | version_compile_machine | x86_64 | | version_compile_os | Linux | +-------------------------+---------------------+ 7 rows in set (0.00 sec) MariaDB [testdb]> show create table test \G *************************** 1. row *************************** Table: test Create Table: CREATE TABLE `test` ( `datetime` datetime NOT NULL ) ENGINE=MyISAM DEFAULT CHARSET=latin1 1 row in set (0.00 sec) MariaDB [testdb]> select datetime from test; Field 1: `datetime` Catalog: `def` Database: `velocitynorep` Table: `test` Org_table: `test` Type: DATETIME Collation: binary (63) Length: 19 Max_length: 19 Decimals: 0 Flags: NOT_NULL BINARY NO_DEFAULT_VALUE +---------------------+ | datetime | +---------------------+ | 2015-09-18 09:23:21 | +---------------------+ 1 row in set (0.00 sec) MariaDB [testdb]> select date_sub(datetime,interval 1 second) from test; Field 1: `date_sub(datetime,interval 1 second)` Catalog: `def` Database: `` Table: `` Org_table: `` Type: DATETIME Collation: binary (63) Length: 19 Max_length: 19 Decimals: 0 Flags: BINARY +--------------------------------------+ | date_sub(datetime,interval 1 second) | +--------------------------------------+ | 2015-09-18 09:23:20 | +--------------------------------------+ 1 row in set (0.00 sec) MariaDB [testdb]> select substr(datetime,1,13) from test; Field 1: `substr(datetime,1,13)` Catalog: `def` Database: `` Table: `` Org_table: `` Type: VAR_STRING Collation: utf8_general_ci (33) Length: 39 Max_length: 13 Decimals: 31 Flags: NOT_NULL +-----------------------+ | substr(datetime,1,13) | +-----------------------+ | 2015-09-18 09 | +-----------------------+ 1 row in set (0.00 sec) MariaDB [testdb]> select concat(substr(datetime,1,13),':00:00') -> from test; Field 1: `concat(substr(datetime,1,13),':00:00')` Catalog: `def` Database: `` Table: `` Org_table: `` Type: VAR_STRING Collation: utf8_general_ci (33) Length: 57 Max_length: 19 Decimals: 31 Flags: NOT_NULL +----------------------------------------+ | concat(substr(datetime,1,13),':00:00') | +----------------------------------------+ | 2015-09-18 09:00:00 | +----------------------------------------+ 1 row in set (0.00 sec) MariaDB [testdb]> select concat('2015-09-18 09',':00:00'); Field 1: `concat('2015-09-18 09',':00:00')` Catalog: `def` Database: `` Table: `` Org_table: `` Type: VAR_STRING Collation: utf8_general_ci (33) Length: 57 Max_length: 19 Decimals: 31 Flags: NOT_NULL +----------------------------------+ | concat('2015-09-18 09',':00:00') | +----------------------------------+ | 2015-09-18 09:00:00 | +----------------------------------+ 1 row in set (0.00 sec) MariaDB [testdb]> select date_sub(concat('2015-09-18 09',':00:00'), -> interval 1 second); Field 1: `date_sub(concat('2015-09-18 09',':00:00'), interval 1 second)` Catalog: `def` Database: `` Table: `` Org_table: `` Type: STRING Collation: binary (63) Length: 19 Max_length: 19 Decimals: 0 Flags: BINARY +---------------------------------------------------------------+ | date_sub(concat('2015-09-18 09',':00:00'), interval 1 second) | +---------------------------------------------------------------+ | 2015-09-18 08:59:59 | +---------------------------------------------------------------+ 1 row in set (0.00 sec) MariaDB [testdb]> select -> date_sub(concat(substr(datetime,1,13),':00:00'), -> interval 1 second) from test; Field 1: `date_sub(concat(substr(datetime,1,13),':00:00'), interval 1 second)` Catalog: `def` Database: `` Table: `` Org_table: `` Type: STRING Collation: binary (63) Length: 26 Max_length: 26 Decimals: 6 Flags: BINARY +---------------------------------------------------------------------+ | date_sub(concat(substr(datetime,1,13),':00:00'), interval 1 second) | +---------------------------------------------------------------------+ | 2015-09-18 08:59:59.000000 | +---------------------------------------------------------------------+ 1 row in set (0.00 sec) The last one is the one that has me stumped. 1.) Why does it include milliseconds in the output? According to this page: https://mariadb.com/kb/en/mariadb/microseconds-in-mariadb/ where no precision is specified the result should not display milliseconds, which is what happens in all the other examples above except this one. 2.) The statement on a 5.1 MySQL server (5.1.73-log, also 64 bit Linux) produces this: mysql> select date_sub(concat(substr(datetime,1,13),':00:00'), -> interval 1 second) from test; Field 1: `date_sub(concat(substr(datetime,1,13),':00:00'), interval 1 second)` Catalog: `def` Database: `` Table: `` Org_table: `` Type: STRING Collation: binary (63) Length: 29 Max_length: 19 Decimals: 31 Flags: BINARY +---------------------------------------------------------------------+ | date_sub(concat(substr(datetime,1,13),':00:00'), interval 1 second) | +---------------------------------------------------------------------+ | 2015-09-18 08:59:59 | +---------------------------------------------------------------------+ 1 row in set (0.00 sec) Is there some global variable I can set to revert to the 5.1 behavior? I realize I can CAST the result to a datetime to make sure I don't get the fractional seconds, but as I mentioned we're converting our system over to 5.5 and there's boatloads of code that I would have to scan through to try and find these differences. 3.) If there is no way to revert to the 5.1 behavior, can someone help me to understand the exact reason why the milliseconds get displayed on the final select in MariaDB 5.5? I'll need to look for any similar types of results and other than the exact reduction above I'm not sure what statements I would need to identify and test. Thanks for any assistance! Dan Ragle

[Maria-discuss] doubt about merge table (10000+) with same structure
by Roberto Spadim 23 Sep '15

23 Sep '15

Hi again guys :) i'm with a new problem i have MANY (10000+) tables with same struct, and i want to execute a select from "some" (100+) tables i was thinking about creating a view with all tables, something like: CREATE VIEW view_name AS SELECT * FROM table1 WHERE primary_key=<a value only at table1> UNION ALL SELECT * FROM table2 WHERE primary_key=<a value only at table2> UNION ALL SELECT * FROM table3 WHERE primary_key=<a value only at table3> UNION ALL SELECT * FROM table4 WHERE primary_key=<a value only at table4> UNION ALL ... SELECT * FROM tablen WHERE primary_key=<a value only at tablen> but i don't know if mysql optimizer will do a good job when i execute something like: SELECT * FROM view_name WHERE primary_key=<a value only located at table1> and just execute the query at table1 instead of alllllllll 10000+ tables i'm considering restruture database to a spider engine or any other method if i don't have other option any idea is well come -- Roberto Spadim

We use keepalived module to load balancing IP address . But we found out one of two servers offline for few days. When I start the offline server (server A), the online one (server B) take a long time to replicate to server A, run out of the server's resources. Could Mariadb masters tell me how to deal with this issue ? How could I sync online data to offline one, and make two servers run well online ? Thank you. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/which-is-the-best-solution-to-re-sync-data-if-one-…

[Maria-discuss] ODBC.NET DOWNLOAD
by Bruce Carlson 17 Sep '15

17 Sep '15

Hi, I'm trying to download the latest stable version of the MariaDB .net ODBC install MSI but every time I try I get directed to a log in page where I can't get any further unless I create some sort of personal information divulgence account. I have never had to do this before with any open source software. Where can I go to download the MSI without having to create an account that I have no intentions of ever doing. I have been using MySQL ever since the early days of version 3 something and have been using MariaDB ever since inception after the split with MySQL. I'm a dedicated and heavy user and supporter of MariaDB and have been for decades. If I am no longer able to download updates etc. without having to create some sort of GOOGLE account then I will not use MariaDB, I will find an alternative. Please advise. Bruce Carlson

Re: [Maria-discuss] ODBC.NET DOWNLOAD
by Bruce Carlson 17 Sep '15

17 Sep '15

Hi Jan, Appreciate your comments however the issue is not the availability of the source or my ability to compile my own binaries from the source and I would even be glad to pay a fee for the convenience of downloading a pre built MSI when installing on windows machines and I am reasonably happy with the occasional donations to open source I've been able to extract from my clients. (Although, I admit, we could all possibly do more in the area of digging up donations and raising funds is a constant issue for all open source organisations). My complaint is I object to being SPECIFICALLY targeted by advertising. The only benefit derived from insisting on this type of "account" is to directly target advertising. THERE IS NO OTHER BENEFIT. I do not object to advertising. When I'm browsing MariaDB I expect to get advertising from MariaDB and maybe some affiliates. And MariaDB has some excellent affiliates. I'm on the mailing lists and forums of several open source communities. They constantly send me advertising matter. I contribute. I donate. I do OBJECT to DIRECT TARGETING. Here is just one example of how this works :- Every time I use a web browser to search for any subject, the search engine will target me with advertising from those businesses that have specified my credentials with the search provider thereby denying me access to alternatives. And that is a very real concern and in my opinion is totally contrary to the principles of open source. It's at least contrary to my principles. Now you may think this is trivial and I'm over reacting but I want to be the person in charge of what information I'm fed. No matter how trivial that sounds to you. In the end, if the only way I can get hold of the binaries is to download the source and build my own, I will or find an alternative product. On a completely separate note, Whilst I disagree with you on the subject of direct targeting I completely agree with your attitude to renewables. And I feel just as strongly about both subjects.

My understanding -- correct me if I'm wrong -- is that the SOURCE is freely downloadable, and that the extra content you vociferously object to is only presented if you choose to download a BINARY. Compiling, maintaining, and debugging binaries is NOT part of the "open source" agreement! Rather, it is a service for which one might expect to be compensated. If you want to compile and maintain and debug the SOURCE and provide binaries without advertising, YOU CAN! NO ONE IS STOPPING YOU! Again, my apology if I'm misunderstanding something, but I used Homebrew to download and compile the SOURCE for MariaDB, and I don't recall seeing ANY advertising of any sort. :::: We are like tenant farmers chopping down the fence around our house for fuel when we should be using nature's inexhaustible sources of energy - sun, wind and tide.

[Maria-discuss] New Question: Galera mysqld_multi - possible bug
by AskMonty KB 16 Sep '15

16 Sep '15

Hello, A new question has been asked in "MariaDB Community" by cisaksen. Please answer it at http://mariadb.com/kb/en/galera-mysqld_multi-possible-bug/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Not sure where to post this but I've come across this on a SLES 12 system. Running Galera 25.3.9-1 / MariaDB 10.1.6-1. Using the Mysqld_multi init.d script to start and stop multiple mysql instances through service or systemd commands I have found that the starting works just fine but stopping them doesn't. It will stop all the instances but the last one. Just for clarification cmd is : service mysqld_multi stop or systemctl stop mysqld_multi. I tried this with 2 and 3 mysql instances. With 2 instances, #1 would stop but #2 wouldn't. With 3 instances #1 & #2 would stop and #3 wouldn't. I have verified that the mysqladmin command works to shut the DB down with the multi_admin account I use. Now running mysqld_multi directly works just fine. Whether it's one specific instance or all of them. That is running the script directly /etc/init.d/mysqd_multi or the actual /usr/bin/mysqld_multi command directly. Both work as expected. I honestly don't know if this is a script problem or a systemd problem. I do know that in SLES 12, SUSE rewrote the mysql init.d script to include mysqld_multi if multiple instances were discovered in the my.cnf file. And this work great using systemd. Anyway there it is, if anyone has come across this on other systems it might be worth noting. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/galera-mysqld_multi-possible-bug/

[Maria-discuss] New Question: Connecting Issue

Hello, A new question has been asked in "Development" by isyed. Please answer it at http://mariadb.com/kb/en/connecting-issue/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hello. I've just downloaded and started using the C/C++ connector library (v.2.1.0), libmariadb.dll. I had simply dropped it in as a direct replacement for the MySQL C connector library (v.6.1.6 x64), libmysql.dll. While it works as expected, there is an unduly long lapse during mysql_real_connect(), lasting for about fifteen seconds, before the connection is established. With libmysql.dll, the connection is almost immediate. Might there be any additional setting that I may have missed to prevent this lapse?

[Maria-discuss] New Question: Hybrid replication - issue
by AskMonty KB 11 Sep '15

11 Sep '15

Hello, A new question has been asked in "Replication, Cluster, & Multi-Master" by truptimali. Please answer it at http://mariadb.com/kb/en/hybrid-replication-issue/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hi, I have been trying to implement a Hybrid replication. There is Async replication configured between two galera clusters. To begin with I have been trying this out on two datacenters dc1 and dc2. dc1 has two node galera cluster -- node1_dc1 , node2_dc1 dc2 has one node - just one primary galera node . node1_dc2 I have configured async replication between node1_dc1 and node1_dc2. But I am facing strange problem here. I could see replication happening nicely on all the three nodes involved. But When i tried to restart node2_dc1 ,(the secondary node from dc1's galera cluster) - i am not able to login to this node's mysql with root user. Or any user for that matter.

Please answer it at http://mariadb.com/kb/en/mariadb-galera-bootstrap/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Are there any references for a MariaDB Galera setup on a systemd system (SUSE 12). Having trouble getting the bootstrap to work. I can get the db to run but it won't connect to the galera provider. Not only that but i have to run /etc/init.d/mysql start --wsrep-new-cluster to get the script to accept the parameter. If I use service or systemctl they both return invalid parameter or option. Another thing is when I do run /etc/init.d/mysql it will start but systemctl status mysql won't know about it.

[Maria-discuss] Double linked list
by Roberto Spadim 28 Aug '15

28 Aug '15

hi guys, i'm with some doibts... I'm trying to replicate a double linked list, my information is: 1) insert at position xxx (and move others to next position) 2) update position yyyy 3) change position zzz with www 4) delete position xxxx to vvvv 5) return all positions 6) return positions with value > zzz My doubt is... I have only one writer and many many readers, writer can't be blocked for more than 1-3 seconds Some times i need to read history (functions 1 to 6) and recreate the linked list at a point in time List is something like: Position - json structure (arraylist in c#) like 0-[0,1,2,4,5] 1-[2.3,4,8,0] It update very fast, minimal update interval is 0.001second (max of 1000updates per second) for each list I will have 100-2000 lists --- Doubts : 1) Whats the best method to create the current double linked list? (The list positioned at last operatiom) A memory table? A row level lock table? A cache solution (memcached) with only one key-value and value with the full list? 2) considering a table: 2.1)what the best method to change position? Update set position=if() where position in (xxx, yyy) In this case what should be the primary key? If i use positionas primary key in this update i cam have non unique values... 2.2) ehat to do with delete/inserts? Insert+update positions? Delete+update positions? 3) any idea if oqgraph could solve this or if there's a storage engine solving this problem? Thanks guys :) -- Roberto Spadim SPAEmpresarial - Software ERP Eng.

Please answer it at http://mariadb.com/kb/en/visual-studio-mariadb-entity-framework-6/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Dear Specialists, We can use at the moment "Visual Studio ADO.NET Driver for MySQL" (https://www.mysql.com/products/connector/) and also there was lots of work done with Visual Studio Integration for MySQL. (http://dev.mysql.com/doc/connector-net/en/connector-net-visual-studio.html) The question is while now it is compatible with MariaDB and I can use MariaDB instead of MySQL, how long if at all there will be a point when this won't become anymore compatible. Is this connection compatibility related with a core or some layer in MariaDB which doesn't change and so it should be working in the future. The reason I am asking is to decide with the strategy. I am testing MariaDB with Entity Framework and the driver/connection mentioned above and it is working but what if you deviate from the connectivity at certain point? Thank you. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/visual-studio-mariadb-entity-framework-6/

This seems to be the only thing stopping automatic cluster recovery. Where is mariadb looking for the file, or is there a way of configuring the file location? Thanks, M

[Maria-discuss] New Question: Fitting index not used
by AskMonty KB 19 Aug '15

19 Aug '15

Hello, A new question has been asked in "Query Optimizations" by mandark. Please answer it at http://mariadb.com/kb/en/fitting-index-not-used/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- MariaDB version: mysql Ver 15.1 Distrib 10.1.2-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2 Here is the simplified situation (Query with like 10 joins, so I simplify to the simpliest query still reproducing the problem when working on slow queries): ``` SELECT article.article_id FROM article -- USE INDEX (s_ti_pd) LEFT JOIN member ON member.member_id = article.member_id WHERE article.thema_id = 29 AND article.state = 1 ORDER BY published_date LIMIT 0, 3; ``` - I have an index on `state, thema_id, published_date` which fit particularly well from my point of view (Query run in a few milliseconds using it) - When using `state, thema_id, published_date` index, explain give me: key_len: 8, ref: const,const, rows: 15006, filter: 100.00, Using where - I have another index on `published_date` only (Query run in ~1s using it) - When using `published_date` index, explain give me: key_len: 9, rows: 94, filtered: 100.00, Using where - Table have a few other indexes... - Forcing the usage of the index ran my query in a few milliseconds, without, one second. - Removing the LEFT JOIN makes MariaDB use the good index - Changing the thema_id sometimes change the index used I dont see any factor that may tell the query optimizer to use published_date. In fact I see only one, it's shorter, so faster to read. But the `status, thema_id, published_date` index seems, for me, obviously better, as it starts with two consts, and also can be used for the ORDER BY. What can I do to understand MariaDB on this choice ? I only tried an "analyze table" but engine side, not "table side", for the moment, it changed nothing. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/fitting-index-not-used/

If a base table is substituted, the query succeeds in both mariadb and mysql. So apparently mariadb cannot match against views. Is there a solution to this? It's messing up my migration.

[Maria-discuss] Travis-CI and MariaDB
by Daniel Black 24 Jul '15

24 Jul '15

For those that use or develop open source or commercial projects that use Travis CI MariaDB has been added as a plugin. This installs either 5.5, 10.0 or 10.1 from the latest MariaDB repo against for testing. Documentation isn't up yet however it is planned. ref: https://github.com/travis-ci/travis-build/pull/303 As an example of Syntax (https://github.com/grooverdan/PyMySQL/blob/c05bf7c6d0f3161d91b3e1418ac185b8…) to test against all MariaDB versions as well as the pre-installed MySQL. Quick snippet: matrix: include: - addons: mariadb: 5.5 - addons: mariadb: 10.0 - addons: mariadb: 10.1 So add it to your own project's .travis.yml or send a PR to your favourite github project that can use MariaDB and Travis-ci. As for MariaDB-server in Travis-CI? we'll see if the bug committing fairies decide https://github.com/MariaDB/server/pull/84 is useful. -- -- Daniel Black, Engineer @ Open Query (http://openquery.com.au) Remote expertise & maintenance for MySQL/MariaDB server environments.

[Maria-discuss] stored procedures external languages
by Federico Razzoli 23 Jul '15

Hi all I remember these slides and this worklog about supporting external languages for stored procedures: * http://www.slideshare.net/AntonyTCurtis/external-stored-proceduresformysql2… * http://www.slideshare.net/AntonyTCurtis/a-tour-of-external-language-stored-… * https://dev.mysql.com/worklog/task/?id=820 As far as I can guess from the slides, there has been some active work on this idea, and some working code. I hoped so badly that I could see this in 5.x, and then in10.0, and then in 10.1. Is there any chance to see this feature in a future release, or should I just stop waiting? Please, consider all the benefits that would come from this: using a "real" language, using existing libraries, getting rid of almost all current stored procedures limitations... Regards Federico

[Maria-discuss] will maria db overcome mysqls feature limitations? (foreign keys+triggers, recursive triggers)
by Ludwig Gramberg 19 Jul '15

19 Jul '15

Hi, I was wondering if mariadb plans to overcome mysqls limitations such as - foreign key operations do not start triggers - triggers can’t be recursive (error 1442) I know that mariadb wants to be compatible with mysql but maybe these features could be optional? The mysql/mariadb comparison shows additional features which wont break compatibility I guess because they don’t exist in mysql (yet?). But besides additional features, is there a chance that mariadb could ever overcome limitations? Is this even a goal of this project? So far I only found postgres to support these features. Background of this question: I am developing an object relational mapper and my goal is to have the database enforce the consistency. So triggers and foreign key constraints working together are vital for this. regards Ludwig

[Maria-discuss] INSERT IGNORE and triggers
by Federico Razzoli 19 Jul '15

19 Jul '15

Hello. As we all know, IGNORE "catches" some errors and turns them into warnings. But I've noticed that it does not catch the same errors if they were issued by a trigger (using SIGNAL). * Is this by design? * Is this standard SQL behaior? Here is a trigger example to show what I mean: CREATE TRIGGER bi_t BEFORE INSERT ON t FOR EACH ROW BEGIN SIGNAL SQLSTATE '23000' SET MYSQL_ERRNO = 1048; END Regards Federico

[Maria-discuss] mysqlbinlog
by Rhys.Campbell＠swisscom.com 18 Jul '15

18 Jul '15

Hello All, I've been playing with mysqlbinlog today. I'm Looking at performing backups of the binary logs. The MariaDB<https://mariadb.com/kb/en/mariadb/mysqlbinlog-options/> mysqlbinlog lags behind the MySQL<https://mariadb.com/kb/en/mariadb/mysqlbinlog-options/> version in the sense it's missing a few features. Namely the ability to 'tail' a live binary log... mysqlbinlog --read-from-remote-server --host=host_name --raw --stop-never binlog.000999 I haven't fully tested this but running the MySQL version against MariaDB doesn't appear viable. I'm probably going to fall back to a FLUSH LOGS / file copy solution for the moment. What would be the chances of back-porting these features into the MariaDB version? Cheers, Rhys

[Maria-discuss] Getting PAM auth to work with JDBC
by Troels Arvin 16 Jul '15

16 Jul '15

I've got the PAM authentication to work, as long as I use a plain command line MariaDB client or HeidiSQL. But I need things to work with JDBC as well. I've found some instructions what seem to indicate that I need to somehow make the JDBC connection use SQL and plain-text authentication. But I have not been able to find specific instructions on doing that. (The instructions, I've seen seem to mainly point to other documents in a circular/byzantine way.) Has someone got the combination of a JDBC client and an PAM-enabled MariaDB server to work? If so: Can you shed some light on the steps you went through? Thanks in advance. -- Regards, Troels Arvin http://troels.arvin.dk

[Maria-discuss] New Question: ERROR 1932 on a table with recently added VIRTUAL column

Hello, A new question has been asked in "MariaDB Community" by Bytesmiths. Please answer it at http://mariadb.com/kb/en/error-1932-on-a-table-with-recently-added-virtual-… as the person asking the question may not be subscribed to the mailing list. -------------------------------- Using version "10.1.0-MariaDB-log - Source distribution" on MacOS X Server 10.6.8 via phpMyAdmin 4.1.8 using raw SQL, I recently used ALTER TABLE to add a VIRTUAL column to a table that was the simple difference between two columns: "ALTER TABLE s_vehicle_log ADD COLUMN v_distance INT(5) AS (odometer - begin) AFTER odometer". This first appeared to work; I could see the new column in phpMyAdmin and it appeared to have the proper values. But within an hour, I could no longer access that table. Going into the mysql CLI, executing "SELECT count(*) FROM s_vehicle_log;" yields "ERROR 1932 (42S02): Table 'EcoReality.s_vehicle_log' doesn't exist in engine" (I do the same on other tables in the same database successfully.)

[Maria-discuss] doubt - replication at same mysqld process
by Roberto Spadim 15 Jul '15

15 Jul '15

hi guys, i have a doubt about replciation on same machine, i never did this before i have a table running many writes and few reads, and another process start reading a lot, my today solution is replication on two servers (on same machine or other machine), the point is... could i replicate in same server (with only one server running / only one mysqld process) ? something like change table A, and a background process replicate to table B? "many writes" will write at table A, reads will read table B (read can be out of sync) innodb is locking a lot of rows, and myisam/aria is locking table a lot, both engines i have problem with lock, i consider replication to another mysqld process as the only solution, but i'm considering running only one mysqld process (if possible) i was thinking about something like HA in spider, but i didn't tested, maybe with flexviewcdc i could have a materialized view "B" of table A? any idea/help is wellcome -- Roberto Spadim

[Maria-discuss] ssd and hdd
by Roberto Spadim 12 Jul '15

12 Jul '15

hi guys i`m with a doubt... i have a server with ssd raid 10 array and hdd raid10 array ssd is faster for non sequencial read that's a fact when i change a table from one device to another and check query response histograms my doubt is... today i have myisam, aria, innodb and sometimes tokudb and spider at same server how could i easily select what table should be stored at ssd or hdd array? there's a "table space" to select if i want to use ssd or hdd instead of create table, and create symbolic links, or create table with data directory/index directory? i was thinking about something more easily understood like tablespace, but used by all engines something like create table blabla table space ssd create table blabla table space hdd what i'm doing today... i have many tables that i use normally and don't drop, these tables i can symbolic link to ssd or hdd, but all new tables i use hdd (they normally are temporary tables), i'm using innodb per file, tokudb i'm not using too much but i don't care about where it's today anyone with experience to help or ideas? -- Roberto Spadim

[Maria-discuss] New Question: Joomla 1.5 and unicode databse
by AskMonty KB 12 Jul '15

12 Jul '15

Hello, A new question has been asked in "Moving to MariaDB" by alijam. Please answer it at http://mariadb.com/kb/en/joomla-15-and-unicode-databse/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- I have a server which (unfortunately) have tens of joomla 1.5 websites, After upgrade from Mysql to Mariadb 10 , all of the unicode texts are being displayed as question marks (i.e. ?????? ????), I looked into the databases , the data seems to be intact, even I moved some of them to another server with mariadb 5.6 which "seems" ok. It seems to be a driver/configuration issue. It works on later versions of joomla (2.5& 3.x) versions. It seems mariadb should also be compatible with joomla 1.5 In the joomla system information it says: Database Version: 10.0.20-MariaDB Database Collation: N/A (mySQL < 4.1.2) PHP Version: 5.4.41 Web Server: Apache Web Server to PHP interface: cgi-fcgi Joomla! Version: Joomla! 1.5.26 Stable [ senu takaa ama busani ] 27-March-2012 18:00 GMT User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:39.0) Gecko/20100101 Firefox/39.0 Any help would be greatly appreciated , as I'm going to upgrade my other servers to mariadb.
