解决为'*********' 的游标已存在问题

出现名为'MM_CURSOR' 的游标已存在。 
一般出现这样的问题是： 
1：游标没有    --关闭 释放 
如： 

--关闭游标
      CLOSE MM_CURSOR
        --释放游标
     DEALLOCATE MM_CURSOR

2：游标已存在同名情况，此时就需要在定义游标时申明一个局部的游标 
如： 

/*检索已经配置好的新村镇的所有乡级部门*/
   ---申明游标
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'

其实我的情况都不是这样，只是在使用嵌套多层循环操作时把两个游标全部放在存储过程末后 

--关闭游标
      CLOSE MM_CURSOR
        --释放游标
     DEALLOCATE MM_CURSOR
   --关闭游标--释放游标
CLOSE deptCursor
   --释放游标
DEALLOCATE deptCursor

没有及时关闭导致问题出现！ 
正确代码如下 

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)
    declare @deptsimplename varchar(100)
    declare @distid bigint
    declare @deptuncode varchar(100)
    declare @deptqueryno varchar(100)
    declare @ifreport varchar(4)
    declare @deptsort int
    declare @enable varchar(6)
    declare @deptfloor smallint
    declare @deptcharacter varchar(50)
    declare @caseSMSFlag varchar(4)
    declare @deptType varchar(1)
    declare @DeNo bigint
    set nocount on
    begin
    set  @deptcode = '2000000'
    /*检索已经配置好的新村镇的所有乡级部门*/

    where  PARENTID=250 and deptType='2'
    ---打开游标

            Order by DEPTCODE /**ONLY VALID DEPARTMENT */
            -- 打开游标
            open MM_CURSOR

            while (@@FETCH_STATUS = 0)
                BEGIN
                 set @deptcode = convert(varchar(20),cast(@deptcode as int)+1)
                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
            --关闭游标
          CLOSE MM_CURSOR
         --释放游标
         DEALLOCATE MM_CURSOR
        FETCH NEXT FROM deptCursor INTO @deptname,@deptsimplename,@distid,@deptuncode,@deptqueryno,@ifreport,@deptsort,@enable,@deptfloor,@deptcharacter,@caseSMSFlag,@deptType
                                        --@deptname,@deptsimplename,@distid,@deptuncode,@deptqueryno,@ifreport,@deptsort,@enable,@deptfloor,@deptcharacter,@caseSMSFlag,@deptType
        end

    end

    --关闭游标
    CLOSE deptCursor
    --释放游标
    DEALLOCATE deptCursor

此外，在刚开始调用存储过程还遇到一个问题:程序处于正在查询状态，近一个小时，我想，数据还没那么复杂，可能出现死循环或某个游标没有移动... 
可是看了代码，没有出现这样的情况， 
经同事指点： 

---申明游标
            Declare MM_CURSOR CURSOR
            local  FOR
            Select DEPTID from t_department where  ENABLE= '启用' 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 */
            -- 打开游标
            open MM_CURSOR
            --循环取出游标
            FETCH NEXT FROM MM_CURSOR  INTO @DeNo
            while (@@FETCH_STATUS = 0)
                set @deptcode = convert(varchar(20),cast(@deptcode as int)+1)   //把此行代码移至begin代码内即可
                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
            --关闭游标
          CLOSE MM_CURSOR
         --释放游标
         DEALLOCATE MM_CURSOR
