[Maria-discuss] New Question: COUNT not working on XAMPP
by AskMonty KB 12 Feb '16

12 Feb '16

Hello, A new question has been asked in "SQL Commands" by styxlawyer. Please answer it at http://mariadb.com/kb/en/count-not-working-on-xampp/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- I have just installed XAMPP version 7.0.2 which incorporates MariaDB. I have added a table called repairs to the test database and it works fine with various PHP pages I have written. However, when trying to use a simple query like: SELECT COUNT (*) FROM repairs I get the following error message: #1630 - FUNCTION test.COUNT does not exist. Check the 'Function Name Parsing and Resolution' section in the Reference Manual This happens in both phpMyadmin and in PHP pages which are accessing the database. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/count-not-working-on-xampp/

[Maria-discuss] JSON in MySQL and MariaDB
by Peter Laursen 11 Feb '16

11 Feb '16

I wonder if someone are able to summarize differences (and similarities - if any ;-) ) between MariaDB and MySQL as regards JSON. I a not really able to structure it myself. MySQL has introduced the JSON datatype https://dev.mysql.com/doc/refman/5.7/en/json.html. I don' tbelieve it is availale in MariaDB. The slides here http://www.slideshare.net/blueskarlsson/using-json-with-mariadb-and-mysql tell that dynamic columns should be used with JSON and MariaDB. Also how much do the functions in both servers for manipulating JSON differ? Are they just named diferently in some cases but doing basically the same? What manipultion options does one have that the other has not (and vice versa). Also :does MariaDB have any plans to move closer to MySQL in 10.2 (such as introducing the JSON datatype and related syntax and funtionalities, for instance)? We would like to add JSON handling capabilites in our (SQLyog) GUI client soon. But the 'uneven' implementation in MariaDB and MySQL is indeed a problem. I think the reply to questions above would be approproate for a Blog, BTW. (@Anders - something for you?) -- Peter Laursen -- Webyog

[Maria-discuss] New Question: setNString method not implemented in PreparedStatement class
by AskMonty KB 11 Feb '16

11 Feb '16

Hello, A new question has been asked in "MariaDB Connector/J" by Sebastian_S. Please answer it at http://mariadb.com/kb/en/setnstring-method-not-implemented-in-preparedstate… as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hi, I do not know if it proper place to ask something like that, but did not find better place. Recently I'd like to connect log4j2 to MariaDB database via MariaDB Connector/J (version 1.3.5, but tested each other). I could not do that and I found that reason is in connector - MariaDbServerPreparedStatement class does not implement method setNString and AbstractMariaDbPreparedStatement class throws exception "NStrings not supported". Why it is not supported. MariaDB does not support such type or it is just a bug? When I copied code form setString method to setNString then everything works properly. Regards, Sebastian -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/setnstring-method-not-implemented-in-preparedstate…

Please answer it at http://mariadb.com/kb/en/mysql-connector-bug-with-bulk-insert/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- I'm new to MariaDB and testing with some applications. Yesterday I met a wired bug. When I using bulk insert with MariaDB connector 1.3.4, following errors occur. (Ubuntu 14.4 and MariaDB 10.1.11) When I replace the connector driver with 'MySQL connector', It works fine. The reference Q&A was http://stackoverflow.com/questions/18693800/mariadb-jdbc-connection-fails-d… The reason that I call this bug is wired was, with same mariadb connector I haven't met bug in any other systems, Mac/Centos 6. Even more another ubuntu system MariaDB 10.1.10 with same driver, no error occurs. works fine: Linux ubuntu 3.13.0-34-generic #60-Ubuntu SMP Wed Aug 13 15:45:27 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux Error occurred system: No LSB modules are available.

[Maria-discuss] New Question: How to change Innodb fileformat to Barracuda
by AskMonty KB 07 Feb '16

07 Feb '16

Hello, A new question has been asked in "XtraDB and InnoDB" by gijs. Please answer it at http://mariadb.com/kb/en/how-to-change-innodb-fileformat-to-barracuda/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- I've attempted to change to the new barracuda file format. I'm using a Galera cluster (MariaDB 10.1.11) and have innodb_file_format=Barracuda set on all my servers, I've rebooted the servers and exported a database with phpmyadmin. After this I deleted the database and recreated it and then imported the previously exported .sql file with phpmyadmin. I checked the file format in INFORMATION_SCHEMA.INNODB_SYS_TABLES and found that it's still set as Antelope. Why is it not set to Barracuda? How can I change it to Barracuda? -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/how-to-change-innodb-fileformat-to-barracuda/

[Maria-discuss] MariaDB JIRA is moving
by Rasmus Johansson 05 Feb '16

05 Feb '16

The MariaDB JIRA instance that currently is in use for project and issue tracking will change. The current instance is hosted in Atlassian's cloud and it has worked well, but we have hit the maximum user limit of 2000 users. It's fantastic to see how many of you actually report bugs and other issues in the MariaDB project! To hit that limit also means that we have to migrate over to a self-hosted instance of JIRA. Below are important details about that change. When will the switch happen: Sat 27th of Feb What is the impact for me as a user of MariaDB's JIRA: 1. URL change - The current instance is hosted in Atalassian's cloud and has the URL mariadb.atlassian.net. The new one will be found at jira.mariadb.org starting from 28th of Feb. 2. RSS feeds - If you have been using JIRA's RSS feeds, you'll need to set up them again since the URL is changing What will happen to old JIRA: The mariadb.atlassian.net JIRA instance will be put into read-only mode and a banner will be visible on each page telling the URL of the new MariaDB JIRA instance. It will remain this way for some time since it has been referenced quite heavily from other sites. source: https://mariadb.org/mariadb-jira-is-moving/ -- Rasmus Johansson, VP Engineering MariaDB | t: +358 50 499 9589 | Skype: ratzpo
