Having #1093 - You can't specify target table for update in FROM clause problems?
I encountered one today, trying to delete old record in a table based on a select based on a timestamp column in the very same table.
I saw the light when I found this thread:
http://stackoverflow.com/questions/8333...rom-clause
which cheats MySQL by using a temporary table like so ( this is the example from Stack )
| Code: | UPDATE giveaways SET winner = '1' WHERE ID =
(
SELECT id FROM
(
SELECT MAX(ID) as id FROM giveaways
) AS tmptable
) |
