So how can emedded SQL in C to get the record type which returning from plpgsql function?
I have tested as following code:
CREATE OR REPLACE FUNCTION test4(IN a integer, OUT b int,OUT c int) AS $BODY$ declare begin b:=100; c:=200; return; END $BODY$
LANGUAGE 'plpgsql' VOLATILE
COST 100;
// imbedded SQL in C
int test(int a)
{
EXEC SQL TYPE my_type IS STRUCT
{
int b[1];
int c[1];
};
EXEC SQL BEGIN DECLARE SECTION;
my_type ppp;
EXEC SQL END DECLARE SECTION;
EXEC SQL WHENEVER sqlerror SQLPRINT;
EXEC SQL select test4(1) into :ppp;
EXEC SQL COMMIT;
return 0;
}
Running binary cause error:
SQL error: invalid input syntax for type int: "(100,200)",
My project is migrating from Oracle to postgresql,can you help me ?
