Thread: Subqueries returning more than one value?
Hi, I am using a function in a subquery, this works ok: SELECT name, (SELECT p_my_func(1)) AS id FROM test; However I would like to have the function return 2 values into the main query... Something like this: SELECT name, (SELECT p_my_func(1)) AS (id, type) FROM test; Of course this gives the error: ERROR: subquery must return only one column Is there any way around this? Thanks for any help adam -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
