MySQL OPTIMIZE all tables?

Question

MySQL has an OPTIMIZE TABLE command which can be used to reclaim unused space in a MySQL install. Is there a way (built-in command or common stored procedure) to run this o

Answer 1

You can optimize/check and repair all the tables of database, using mysql client.

First, you should get all the tables list, separated with ',':

mysql -u[USERNAME] -p[PASSWORD] -Bse 'show tables' [DB_NAME]|xargs|perl -pe 's/ /,/g'

Now, when you have all the tables list for optimization:

mysql -u[USERNAME] -p[PASSWORD] -Bse 'optimize tables [tables list]' [DB_NAME]
