Soory its not possible. Here a User Comment from the Commented MySqlDoc (Chapter UPDATE Systax)
-------------- Comments: Michael Holopainen: I was looking for info on how-to UPDATE with data retrived from another table. aka. UPDATE with JOIN. I noticed many other people were asking the same question so I desided to write this comment. The answer is : "You can't". Not until MySQL 4.1 that supports sub-selects. Then and only then you can use something like this: UPDATE t1 SET t1.col = (SELECT t2.col FROM t2 WHERE <where clause>) WHERE <where clause>; As far as I can tell not even in MySQL 4.1 can you use JOIN with UPDATE. ----------------- Original Message: ----------------- From: Sommai Fongnamthip [EMAIL PROTECTED] Date: Fri, 15 Feb 2002 16:37:51 +0700 To: [EMAIL PROTECTED] Subject: update data from other table Hi, How to update data in table with data from other table in single SQL command (without using loop)?
