Try something like this
UPDATE table1
SET col1 = b.col1
FROM table1 b
WHERE table1.col2 = b.col2 and
table1.col3 = something and
b.col3 = somethingelse
SET col1 = b.col1
FROM table1 b
WHERE table1.col2 = b.col2 and
table1.col3 = something and
b.col3 = somethingelse

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 cant 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
