Question

我的存储过程遇到了一些麻烦。我写了一个存储过程，我正在使用游标。一切正常，直到我从光标到临时表插入值的地方。这是错误

Msg 156，Level 15，State 1，Procedure ors_DailyReportMessageStatus，Line 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

我可能会忽视某些事情吗？好像我忘记了什么。

尝试更换：

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

使用：

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

我对你的逻辑做了一些假设，所以你可能需要相应调整。

mssql游标的问题很小，在游标中的temp表中插入
