Question
In Oracle I can declare a reference cursor...
TYPE t_spool IS REF CURSOR RETURN spool%ROWTYPE;
...and use it to pass a cursor as the return value...
FUNCTION end_spool
RETURN t_spool
AS
v_spool t_spool;
BEGIN
COMMIT;
OPEN v_spool FOR
SELECT
*
FROM
spool
WHERE
key = g_spool_key
ORDER BY
seq;
RETURN v_spool;
END end_spool;
...and then capture it as a result set using JDBC...
private Connection conn;
private CallableStatement stmt;
private OracleResultSet rset;
[...clip...]
stmt = conn.prepareCall("{ ? = call " + call + "}");
stmt.registerOutParameter(1, OracleTypes.CURSOR);
stmt.execute();
rset = (OracleResultSet)stmt.getObject(1);
What is the equivalent in Postgresql?
Solution
Maybe this will help: http://jdbc.postgresql.org/documentation/83/callproc.html#callproc-resultset-setof
I haven't really messed with that before :P
