hi all, i'm new to the list, so if this is an off-topic question, or
has already been posed, i apologize...
i'm trying to figure out how to get the following test situation to
work:
creating a function like below fails...
CREATE FUNCTION test_function() RETURNS SETOF table.column%TYPE AS $$
SELECT 1; $$ LANGUAGE SQL;
yet i know the %TYPE format works because the below succeeds...
CREATE FUNCTION test_function() RETURNS table.column%TYPE AS $$
SELECT 1; $$ LANGUAGE SQL;
as does the SETOF option because the following also succeeds...
CREATE FUNCTION test_function() RETURNS SETOF int4 AS $$ SELECT 1; $$
LANGUAGE SQL;
can anyone help me figure out how to get the first function
declaration to work?
and yes, i know i could just look up the type of the column of
interest, but i'm trying to make the function somewhat independent of
table alterations (the whole reason for the %TYPE inclusion in
postgresql in the first place!)
thanks for any help!
