Thread: question about PL/pgSQL function

With postgres 7.1
1. Function like example found on 24.4 Example in Programmer Guide   CREATE FUNCTION xxx (EMP, integer) RETURNS boolean
AS'......  (which EMP is a table )   How do I pass a record to this function in PL/PGSQL? I try this
 
....   select into rec1 * from EMP where empNo =''xxxx'';   i1 :=  xxx(rec1,5);
....   But it won't work!
2. Is that possible to return a record from a function? And how do I get the
returned record in PL/pgSql

Bad syntax.  The correct syntax is:
SELECT * INTO rec1 FROM EMP WHERE empNo=''xxxx'';

No, it is not possible.  I know the list archives are kinda hard to
search, but we've discussed this question ad naseum; in fact, I just
provided a workaround earlier this week.

   Not yet. In the current 7.2 development tree it's possible to   return a cursor opened inside of the procedure.
Maybe I  can   even improve it so you can open an empty cursor and *fill* it   like a tuple sink so to speak.  Mainly
dependson if and  how   we want to improve the capabilities of portals.
