[SQL] update syntax

[Praveen Raja]

Hi,   While using Ms SQL server I used to write update statements like this,   UPDATE a SET a.col1 = b.col1 FROM table1 a INNER JOIN table1 b ON a.col2 = b.col2 WHERE a.col3 = ‘something’ AND b.col3 = ‘somethingelse’   But I can’t seem to do this in postgres, it gives me an error saying ‘syntax error at or near “.”’. How can I do something similar to this i.e. join on the same table?   Thanks, /P
