1093 Error in MySQL table is specified twice

Question

I\'m trying to update some rows. I only want to update the rows that have ID=0.

The error message I\'m receiving is:

1093 - Table \'ch_15_posts\' is specifie

Answer 1

You probably need something like that:

UPDATE ch_15_posts AS t1
JOIN (select MAX(ID)+1 as max FROM `ch_15_posts`) AS t2
SET t1.ID = t2.max
WHERE ID = 0
