[Maria-discuss] explain for insert/update/delete
by MARK CALLAGHAN 11 Jul '25

11 Jul '25

Does MariaDB have any plans to support explain for insert/update/delete/replace/CTAS? There have been feature requests open for a very long time on official MySQL without any progress. I have had a few problems in production from 'bad' delete statements that had a very different plan than the select statement with the same where clause. The only way to check for a bad plan today is to use SHOW INNODB STATUS to determine whether the statement locks all rows in a table. http://bugs.mysql.com/bug.php?id=14745 http://bugs.mysql.com/bug.php?id=35355 -- Mark Callaghan mdcallag(a)gmail.com

[Maria-discuss] Generic Linux Build requirements
by Brian Evans 06 Apr '10

06 Apr '10

http://askmonty.org/wiki/index.php/Building_MariaDB:Generic_Linux says: * gcc 2.95.2 or later However, according to [1] , Gentoo claims that GCC 4.3 is required due the use of c++ templates in the server. [2] also states that GCC-4 is absolutely required with a failing build log. [1] http://bugs.gentoo.org/show_bug.cgi?id=307251#c5 [2] http://bugs.gentoo.org/show_bug.cgi?id=284946

[Maria-discuss] Problems with Foreign Key

Hi all, Any idea why I am getting this error: A) ERROR ALTER TABLE login -> ADD CONSTRAINT fk_db_perfil FOREIGN KEY (id_perfil) -> REFERENCES db_perfil (id_perfil) -> ON DELETE NO ACTION -> ON UPDATE NO ACTION;ERROR 1005 (HY000): Can't create table 'dbhomo_aa.#sql-c1f_281' (errno: 150)dbhomo_aa-> dbhomo_aa-> B) HERE IT WORKS dbhomo_aa-> ALTER TABLE login ADD CONSTRAINT fk_db_perfil FOREIGN KEY (id_perfil) REFERENCES dbhomo.db_perfil (id_perfil) ON DELETE NO ACTION ON UPDATE NO ACTION; Query OK, 35199 rows affected (3,27 sec) Records: 35199 Duplicates: 0 Warnings: 0 Note that when I change the database to the original database the command works as expected. Both tables are innodb, the permissions are fine. Thanks, Alex

[Maria-discuss] Maria on Solaris X86
by Jim Grill 18 Mar '10

18 Mar '10

Hello, I’m having trouble getting MariaDB 5.1.42 working on Solaris 10x86. I’ve tried both the Binary package (mariadb-5.1.42-solaris11-i386) and building from source (mariadb-5.1.42). I don't know if it's something in the binary package or source code, something goofy on my system, or something goofy with how I'm building it. I'm assuming the latter, but thought I might bring it up anyway just in case it might help others running Solaris. :-) I can’t get the binary dist to startup. Here’s the error log from the binary dist (note the hostname missing from the error log name)… $ cat data/.err 100212 09:54:33 mysqld_safe Starting mysqld daemon with databases from /data01/mydata/mariadb-bin-tst/data ld.so.1: mysqld: fatal: relocation error: file bin/mysqld: symbol strnlen: referenced symbol not found 100212 09:54:33 mysqld_safe mysqld from pid file /data01/mydata/mariadb-bin-tst/mysql.pid ended I’m using SunStudio 12.1 to build from source.

[Maria-discuss] Gentoo Ebuilds for MariaDB on GitHub
by Brian Evans 17 Mar '10

17 Mar '10

I have posted the build scripts for Gentoo onto GitHub. They can be found here: http://github.com/grknight/mariadb-gentoo Gentoo downstream uses git over bzr so I thought it was the best choice. Feel free to pull from it.

[Maria-discuss] problems with innodb
by Alexandre Almeida 11 Mar '10

11 Mar '10

Hi guys, I am building MariaDB from source and it doesn't come with innodb. I have tried the parameters: all and innobase. Is there anything else I can pass on command line to get innodb running at my MariaDB? Many thanks, Alex
