Hello,
I am using postgres-odbc and I created the following function which is
called from a C-application. This function returns a single argv[0] of the
form (a,b,c,d,e,f,g).
CREATE OR REPLACE FUNCTION PresRoute(int, int) RETURNS
TABLE(d1 text, d2 text, d3 text, d4 text, r1 bigint, r2 bigint, r3 bigint)
AS $$
SELECT PresDest1(PresNode($1,$2)), PresDest2(PresNode($1,$2)),
PresDest3(PresNode($1,$2)),
PresDest4(PresNode($1,$2)), PresRing1(PresNode($1,$2)),
PresRing2(PresNode($1,$2)),
PresRing3(PresNode($1,$2)) $$ LANGUAGE SQL;
But I would like it to return data as argv[0] thru argv[6] as shown:
d1 | d2 | d3| d4 | r1 | r2 | r3

a b c d e f g
How should I change my function definition to achieve this?
I think it's just a matter of how you're calling it. Are you doing this:
SELECT PresRoute(...
or this:
SELECT * FROM PresRoute(...
if you don't want the rowtype, do the latter. The former is roughly
same as doing 'select foo from foo' vs 'select * from foo'.
