以下是我的尝试：

    ,@UserId AS NVARCHAR(50)
)

    ,UserId VarChar(50)
    ,ReviewDate Datetime
    ,Deleted varchar(10)
    ,Audited varchar(10)
    )

    DECLARE @Nos INT = (SELECT COUNT (*) FROM tblItemReviewItems WHERE Deleted='No' AND ReviewDate=@ReviewDate AND UserId=@UserId)
    DECLARE @Yes INT = (SELECT COUNT (*) FROM tblItemReviewItems WHERE Deleted='Yes' AND ReviewDate=@ReviewDate AND UserId=@UserId)
    DECLARE @Samplepct FLOAT =(.05*(@Nos + @Yes)) / @Nos*100

    DECLARE @Percentage AS INT = @Samplepct

    INSERT INTO @tempDashboard (ItemReviewId, UserId, ReviewDate, Deleted, Audited)
    SELECT
        TOP (@Percentage) PERCENT ItemReviewId, UserId, ReviewDate, Deleted, Audited
    FROM
        tblItemReviewItems
    WHERE

我必须为每个用户运行存储过程。通常每天大约有200个用户。所以我必须在一天内运行存储过程200次。我如何一次性实现这一目标？

以下是执行此操作的方法 - 将行选择到临时表中。如果您有主键，则只需选择主键。如果您没有主键，请选择足够的列以使组合具有唯一性。在临时表中获得所需的行后，与该临时表连接并使用您想要的值更新原始表中的那些行。如果您不想对随后选择的行执行任何操作，则可以在使用正确的where子句进行选择后实际更新行。

类似的东西：

ALTER PROC [dbo].[spPickSample] 
AS
 BEGIN
   DECLARE @Nos INT = (SELECT COUNT (*) FROM tblItemReviewItems WHERE Deleted='No' and UserId='jdoe1')
   DECLARE @Yes INT = (SELECT COUNT (*) FROM tblItemReviewItems WHERE Deleted='Yes' and UserId='jdoe1')
   DECLARE @Samplepct FLOAT =(.05*(@Nos + @Yes)) / @Nos*100
   DECLARE @Percentage AS INT = @Samplepct
   DECLARE @temptable table (ItemReviewId nvarchar(50))
   INSERT into @temptable
     SELECT
        TOP (@Percentage) PERCENT ItemReviewId
     FROM
        tblItemReviewItems
     WHERE
        Deleted='No' AND UserId='jdoe1'

    Update t set Audited="Check"
    from tblItemReviewItems t
    where ItemReviewId in (Select ItemReviewId from @temptable)

    Select * from tblItemReviewItems 
    where ItemReviewId in (Select ItemReviewId from @temptable)

 END

假设您的用户位于名为＆＃39; [users]＆＃39;的表中。然后你可以用这种方式循环游标：

DECLARE @userid nvarchar(50)
DECLARE db_cursor CURSOR FOR  
SELECT userid 
FROM [users] 

OPEN db_cursor   
FETCH NEXT FROM db_cursor INTO @userid   

WHILE @@FETCH_STATUS = 0   
BEGIN   
     exec dbo.PickSample '2017-07-01',@userid
       FETCH NEXT FROM db_cursor INTO @userid   
END
