Out of curiosity, what SQL server (and version) are you using? I currently have MySQL 5.0.33 on my dev box and I had no problem with the query I gave you. Perhaps it's a version issue. There really shouldn't be a problem updating a table that also occurs in the select query since the select query should take place before the insert.
He wasn't doing an insert/select, he was doing an update with two tables joined together.
<copy> I thought that -- UPDATE user1 u1, user2 u2 SET u1.login = u2.login, u1.password = u2.password WHERE u1.username = u2.username -- would work, but it don't. -- Postgresql & php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
