DB2 java 存储过程调用返回错误 SQLCODE=-440, SQLSTATE=42884

================ The stored procedure definition:

CREATE PROCEDURE median_result_set
-- Declare medianSalary as OUT so it can be used to return values
(OUT medianSalary DOUBLE)
RESULT SETS 2
LANGUAGE SQL
BEGIN

   DECLARE v_numRecords INT DEFAULT 1;
   DECLARE v_counter INT DEFAULT 0;

   DECLARE c1 CURSOR FOR
      SELECT salary FROM staff
       ORDER BY CAST(salary AS DOUBLE);

  -- use WITH RETURN in DECLARE CURSOR to return a result set
  DECLARE c2 CURSOR WITH RETURN FOR
   SELECT name, job, salary
   FROM staff 
   WHERE CAST(salary AS DOUBLE) > medianSalary
   ORDER BY salary;

  -- use WITH RETURN in DECLARE CURSOR to return another result set
 DECLARE c3 CURSOR WITH RETURN FOR
    SELECT name, job, salary
    FROM staff
    WHERE CAST(salary AS DOUBLE) < medianSalary
    ORDER BY SALARY DESC;

 DECLARE CONTINUE HANDLER FOR NOT FOUND
   SET medianSalary = 6666; 

 -- initialize OUT parameter
 SET medianSalary = 0;

 SELECT COUNT(*) INTO v_numRecords FROM STAFF;

 OPEN c1;

   WHILE v_counter < (v_numRecords / 2 + 1) DO
     FETCH c1 INTO medianSalary;
     SET v_counter = v_counter + 1;
  END WHILE;
  CLOSE c1;

  -- return 1st result set, do not CLOSE cursor
  OPEN c2;

  -- return 2nd result set, do not CLOSE cursor
  OPEN c3;
END @

推荐答案

基本上SQLCODE=-440, SQLSTATE=42884"表示找不到存储过程.
