Question

I have a table delete_requests where I store the id’s for delete requests for the entries of my users table. Is it possible to delete from users with the information from delete_requests as a condition?

My problem is, that the result set will usually not be limited to one row but return several.

DELETE FROM users WHERE id=(SELECT id FROM delete_requests)

So MySQL complains:

#1242 - Subquery returns more than 1 row

Can this be done in one statement without putting the logic into the executing application?

Answer 1

Use the IN clause

DELETE FROM users WHERE id IN (SELECT id FROM delete_requests)
