解決為'*********' 的游標已存在問題

出現名為'MM_CURSOR' 的游標已存在。 
一般出現這樣的問題是： 
1：游標沒有    --關閉 釋放 
如： 

--關閉游標
      CLOSE MM_CURSOR
        --釋放游標
     DEALLOCATE MM_CURSOR

2：游標已存在同名情況，此時就需要在定義游標時申明一個局部的游標 
如： 

/*檢索已經配置好的新村鎮的所有鄉級部門*/
   ---申明游標
DECLARE deptCursor CURSOR
   local FOR
   SELECT  deptname, deptsimplename,distid, deptuncode,deptqueryno,ifreport,deptsort,enable,deptfloor,deptcharacter,caseSMSFlag,deptType

   FROM t_department
   where  PARENTID=250 and deptType='2'

其實我的情況都不是這樣，只是在使用嵌套多層循環操作時把兩個游標全部放在存儲過程末后 

--關閉游標
      CLOSE MM_CURSOR
        --釋放游標
     DEALLOCATE MM_CURSOR
   --關閉游標--釋放游標
CLOSE deptCursor
   --釋放游標
DEALLOCATE deptCursor

沒有及時關閉導致問題出現！ 
正確代碼如下 

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
---drop  PROCEDURE copyDept

ALTER PROCEDURE [dbo].[copyDept]
    as
    declare @deptCode varchar(20)
    declare @deptname varchar(10)

    ---打開游標

                 INSERT INTO T_DEPARTMENT (deptcode, deptname, deptsimplename,distid, deptuncode,deptqueryno,ifreport,deptsort,enable,deptfloor,PARENTID,deptcharacter,caseSMSFlag,deptType)
                                    VALUES (@deptcode,@deptname,@deptsimplename,@distid,@deptuncode,@deptqueryno,@ifreport,@deptsort,@enable,@deptfloor,@DeNo,@deptcharacter,@caseSMSFlag,@deptType)

        end

    end

    --關閉游標
    CLOSE deptCursor
    --釋放游標
    DEALLOCATE deptCursor

此外，在剛開始調用存儲過程還遇到一個問題:程序處於正在查詢狀態，近一個小時，我想，數據還沒那么復雜，可能出現死循環或某個游標沒有移動... 
可是看了代碼，沒有出現這樣的情況， 
經同事指點： 

---申明游標
            Declare MM_CURSOR CURSOR
            local  FOR
            Select DEPTID from t_department where  ENABLE= '啟用' and DISTID = 1 and deptType=0 and deptid !=250---demo,except 250 -- and PARENTID =288--and deptid not in (243,244)--and is_convenience=@tjType jc_dreaming
            Order by DEPTCODE /**ONLY VALID DEPARTMENT */
            -- 打開游標
            open MM_CURSOR
            --循環取出游標
            FETCH NEXT FROM MM_CURSOR  INTO @DeNo
            while (@@FETCH_STATUS = 0)
                set @deptcode = convert(varchar(20),cast(@deptcode as int)+1)   //把此行代碼移至begin代碼內即可
                BEGIN

                print(@deptcode)
                 INSERT INTO T_DEPARTMENT (deptcode, deptname, deptsimplename,distid, deptuncode,deptqueryno,ifreport,deptsort,enable,deptfloor,PARENTID,deptcharacter,caseSMSFlag,deptType)
                                    VALUES (@deptcode,@deptname,@deptsimplename,@distid,@deptuncode,@deptqueryno,@ifreport,@deptsort,@enable,@deptfloor,@DeNo,@deptcharacter,@caseSMSFlag,@deptType)
                FETCH NEXT FROM MM_CURSOR INTO @DeNo
                END
            --關閉游標
          CLOSE MM_CURSOR
         --釋放游標
         DEALLOCATE MM_CURSOR
