MYSQL錯誤：過程不能返回在給定上下文

Question

我在mysql中是新的存儲過程的結果集

這是返回不包括週末日期差異的程序，但它返回錯誤

#1312 - PROCEDURE blog1.DayCount can't return a result set in the given context

這是程序

DROP PROCEDURE IF EXISTS daycount; 
CREATE PROCEDURE DayCount(d1 DATE, d2 DATE) 
SELECT dd.iDiff, dd.iDiff - dd.iWeekEndDays AS iWorkDays, dd.iWeekEndDays 
FROM ( 
    SELECT 
    dd.iDiff, 
    ((dd.iWeeks * 2) + 
    IF(dd.iSatDiff >= 0 AND dd.iSatDiff < dd.iDays, 1, 0) + 
    IF (dd.iSunDiff >= 0 AND dd.iSunDiff < dd.iDays, 1, 0)) AS iWeekEndDays 
    FROM ( 
    SELECT 
     dd.iDiff, 
     FLOOR(dd.iDiff/7) AS iWeeks, 
     dd.iDiff % 7 iDays, 
     5 - dd.iStartDay AS iSatDiff, 
     6 - dd.iStartDay AS iSunDiff 
    FROM ( 
     SELECT 
     1 + DATEDIFF(d2, d1) AS iDiff, 
     WEEKDAY(d1) AS iStartDay 
    ) AS dd 
) AS dd 
) AS dd ; 


CALL DayCount('2009-8-1','2009-9-15');

檢查在MySQL控制檯這個存儲過程，如果它工作正常，你應該檢查你的CA來自PHP。 我發現same problem is happen with other people。
