使用JDBC時，Postgresql中的Oracle REF CURSOR等效於什么？

Question

在Oracle中，我可以聲明一個引用游標...

TYPE t_spool IS REF CURSOR RETURN spool%ROWTYPE;

...並使用它傳遞游標作為返回值...

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;

...然后使用JDBC將其捕獲為結果集...

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);

Postgresql中的等效項是什么？

也許這會有所幫助： http : //jdbc.postgresql.org/documentation/83/callproc.html#callproc-resultset-setof
