mssql游标的问题不大，请在游标中的临时表中插入

如何解决mssql游标的问题不大，请在游标中的临时表中插入

|| 我的存储过程有点麻烦。我已经编写了一个使用游标的存储过程。一切正常，直到我将游标中的值插入到临时表的地方为止。这是错误消息156，级别15，状态1，过程ors_DailyReportMessageStatus，行36 关键字\'where \'附近的语法不正确。这是代码

ALTER PROCEDURE [dbo].[ors_DailyReportMessageStatus]
-- Add the parameters for the stored procedure here
@startDate datetime,@endDate datetime
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
DECLARE @num int;
DECLARE @stat varchar(20);
DECLARE @statusCursor CURSOR 
SET @statusCursor = CURSOR FOR
select count(ms.status) as message,ms.status from message_status ms JOIN [message] m on  m.id=ms.message_id
where (m.ADDED_ON >= @startDate AND m.ADDED_ON < @endDate) GROUP BY ms.status

SET NOCOUNT ON;
if object_id(\'tempdb..#tempdailystatus\') is not null
begin 
   drop table #tempdailystatus
end

CREATE TABLE #tempdailystatus(id int identity,total int,[status] varchar(20));
insert into #tempdailystatus ([status])
 select distinct([status]) from message_status;


 open @statusCursor 
 fetch next from @statusCursor into @num,@stat;
 while @@FETCH_STATUS = 0

    begin 
    -- this is where the error is
    insert into #tempdailystatus (total) values (@num) where id = (select id from   #tempdailystatus where [status] = @stat)
    -- this were just to see whether the cursor is ok. and it is
    --print  @stat
    --print  @num ;
    fetch next from @statusCursor into @num,@stat
 end

 close @statusCursor
 deallocate @statusCursor


 -- Insert statements for procedure here
 -- SELECT * from #tempdailystatus
 drop table #tempdailystatus
END

我可能会忽略什么吗？好像我忘记了什么。感谢您阅读本文并提出建议。不胜感激^ _ ^

解决方法

尝试更换：

insert into #tempdailystatus (total) values (@num) where id = (select id from   #tempdailystatus where [status] = @stat)

与：

If Exists(Select 1 From #tempdailystatus where [status] = @stat)
  Begin
    insert into #tempdailystatus (total) Values(@num)
  End

我对您的逻辑做了一些假设，因此您可能需要进行相应的调整。
