Ok, I wanted to wrap a select statement with a PL/pgsql procedure
(information hiding, etc.)
So I have:
CREATE OR REPLACE FUNCTION user_data_select_all(BIGINT)
RETURNS REFCURSOR AS '
DECLARE
-- parameters
owner_id_p ALIAS FOR $1;
-- local variables
rc REFCURSOR;
BEGIN
OPEN rc FOR SELECT *
FROM user_data
WHERE
owner_id = owner_id_p;
RETURN rc;
END;
' LANGUAGE 'plpgsql' WITH (isstrict);
Now from within psql I get the following:
=> select user_data_select_all(12);
user_data_select_all
----------------------
<unnamed cursor 15>
(1 row)
I kind of expected to see the actual rows?!?
and from JDBC I get an exception:
Bad Long <unnamed cursor 1>
at org.postgresql.jdbc2.ResultSet.toLong(ResultSet.java:1498)
at org.postgresql.jdbc2.ResultSet.getLong(ResultSet.java:257)
So the question is can I wrap a select function as return a resultset to
JDBC?
