I'm trying to delete rows from a table but I get an error.

DELETE FROM `chat_messages` ORDER BY `timestamp` DESC LIMIT 20, 50;

I get this error at 50:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' 50' at line 1

No idea what's wrong.

You cannot specify offset in DELETE's LIMIT clause.

So the only way to do that is to rewrite your query to something like:

DELETE FROM `chat_messages` WHERE id IN (select id from (select id
                                           FROM `chat_messages`
                                       ORDER BY `timestamp` DESC
                                          LIMIT 20, 50) x)

Supposing that you have primary key id column

UPD: you need to implement double nesting to fool mysql, since it doesn't allow to select from currently modified table (thanks to Martin Smith)

MySQL doesn't allow that (Error 1093) unless you add an extra level of nesting. See

+1 beating me to the answer - DELETE accepts rowcount only for LIMIT.

@Martin Smith: what do you mean?

@Martin Smith 2011-08-22 00:33:37

I edited my comment to add further details. If the subquery is directly in the IN you get error "You can't specify target table 'chat_messages' for update in FROM clause". You can get around that by making the subquery a derived table.

@Martin Smith: oh yes, great notice. thank you
