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.
