Обсуждение: subqueries as values in updates

hello, list.
are subqueries alloved as values in an update command ?
e.g.

update a set a.attribute1 = a.attribute1 +   (select sum(b.attribute1) from b where b.attribute2=a.attribute2);

If yes, how is the correct syntax ?
If not, is there a hope for it in a future version ?

Hi,

The syntax you used works fine for me.

francis=# select version();                           version
---------------------------------------------------------------PostgreSQL 7.0.2 on i686-pc-linux-gnu, compiled by gcc
2.95.2
(1 row)

Hope this helps

Francis Solomon
