錯誤在存儲過程（錯誤代碼：1064）

Question

My stored procedure is like this ... 



DELIMITER $$ 

DROP PROCEDURE IF EXISTS `tds_dev`.`BlockTokenSheduler`$$ 

CREATE PROCEDURE `BlockTokenSheduler`(cdate date,shift varchar(20)) 
BEGIN 
     declare lo_SERIALNO int;

     declare lo_NEXTAPPOINTMENTTIME time;

     declare lo_ACTUALFINISHEDTIME time; 
     declare lo_SMSSTATUS varchar(20); 
     declare temp_appTime time;

      Declare btcountcur Cursor for

      declare continue handler for not found set btdone=1; 


      open btcountcur; 


      bt_loop :LOOP 

       if btdone=1 then 
        leave bt_loop; 
        end if; 

       FETCH btcountcur into bt_ADJUSTMENTTIME,bt_NEXTAPPOINTMENTTIME; 

        Declare mycur cursor for 
       select TOKENNUMBER,APPOINTMENTTIME,ADJUSTMENTTIME,CONSULTATIONTYPE,NEXTAPPOINTMENTTIME,CONSULTATIONSTATUS,SMSSTATUS from tds_tokengeneration 
       where TOKENDATE=cdate and SHIFTID=shift and blockstatus='MT'; 
          declare continue handler for not found set done=1; 
        open mycur; 
        time_loop :LOOP 
        FETCH mycur into lo_TOKENNUMBER,lo_APPOINTMENTTIME,lo_ADJUSTMENTTIME, 
           lo_CONSULTATIONTYPE,lo_NEXTAPPOINTMENTTIME,lo_CONSULTATIONSTATUS,lo_SMSSTATUS; 
        if done=1 then 
        leave time_loop; 
        end if; 

       if (lo_ADJUSTMENTTIME >= bt_ADJUSTMENTTIME and lo_APPOINTMENTTIME <= bt_NEXTAPPOINTMENTTIME) or (lo_NEXTAPPOINTMENTTIME >= bt_ADJUSTMENTTIME and lo_NEXTAPPOINTMENTTIME <= bt_NEXTAPPOINTMENTTIME)then 

       set lo_ADJUSTMENTTIME=bt_NEXTAPPOINTMENTTIME; 
       if lo_CONSULTATIONTYPE='C' then 
         set lo_NEXTAPPOINTMENTTIME = ADDTIME(lo_ADJUSTMENTTIME,'00:12:00'); 
        else 
         set lo_NEXTAPPOINTMENTTIME = ADDTIME(lo_ADJUSTMENTTIME,'00:20:00'); 
        end if; 
       update tds_tokengeneration set ADJUSTMENTTIME=lo_ADJUSTMENTTIME, 
          NEXTAPPOINTMENTTIME=lo_NEXTAPPOINTMENTTIME, 
          SMSSTATUS=lo_SMSSTATUS 
          where TOKENNUMBER=lo_TOKENNUMBER and TOKENDATE=cdate and SERIALNO=lo_SERIALNO; 
       end if; 
      end loop time_loop; 
      close mycur; 

     end loop bt_loop; 
    close btcountcur; 

    END$$ 

DELIMITER ; 

。但當我執行這個程序我得到以下錯誤

(0 row(s)affected) 
(0 ms taken) 

Error Code : 1064

Answer 1

Declarations must follow a certain order。 不允許在過程中間聲明遊標或事件處理程序。是的，錯誤信息至少可以說是誤導。您必須在BEGIN ... END塊的開頭聲明mycur光標。

您可以將第二個遊標聲明移動到您的過程的開始位置，或者在適當的位置移動nest a BEGIN ... END block。
