[Maria-discuss] explain for insert/update/delete
by MARK CALLAGHAN 08 Jul '25

08 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

Many thanks Lyallex
