I don't know if you can do that using the same
logic.
Perhaps someone else can help?
For sure, you can use a
subselect.
delete from table1 where col1 in (SELECT
a.col1
FROM table1 a JOIN table1 b ON a.col2 =
b.col2
WHERE a.col3 = �something�
AND b.col3 = �somethingelse�)

Thanks. The UPDATE
works ok now. But using the same logic it doesn�t seem possible to delete
rows. Is this also possible?

update syntax
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
