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 @ifreport varchar(4)
     declare @deptsort int

     FROM t_department
     where  PARENTID=250 and deptType='2'
     ---打开游标
     OPEN deptCursor
     --循环取出游标
     FETCH NEXT FROM deptCursor INTO @deptname,@deptsimplename,@distid,@deptuncode,@deptqueryno,@ifreport,@deptsort,@enable,@deptfloor,@deptcharacter,@caseSMSFlag,@deptType

             FETCH NEXT FROM MM_CURSOR  INTO @DeNo
             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
