Hello,
I am having a problem with a FUNCTION.
The function creates just fine with no errors.
However, when I call the function postgres produces an error.
Perhaps someone can enlighten me.
--I can reproduce the error by making a test function
--that is much easier to follow that the original:
CREATE OR REPLACE FUNCTION test_function(integer)
RETURNS SETOF RECORD AS
$BODY$
DECLARE croid integer;
BEGIN
--PERFORM A SMALL CALCULATION
--DOESNT SEEM TO MATTER WHAT IT IS
SELECT INTO croid 2;
--A SELECT STATEMENT OUTPUTS RECORDS (one in this case)
SELECT croid,$1;
END;
$BODY$
LANGUAGE 'plpgsql' VOLATILE
--The call looks like the following:
SELECT test_function(1);
--The resulting error reads as follows:
ERROR: query has no destination for result data
HINT: If you want to discard the results of a SELECT, use PERFORM instead.
CONTEXT: PL/pgSQL function "test_function" line 5 at SQL statement
********** Error **********
ERROR: query has no destination for result data
SQL state: 42601
