如何在應用分頁後獲取總行數

Question

我正在使用@skip和@take參數進行分頁。分頁後我需要總行數。我怎樣才能做到這一點，作爲表現的最佳方式？

CREATE PROCEDURE Search 
    @Take  Int   = 10 
    @Skip  Int   = 0 
    @TotalRows Int Out 
AS 

    BEGIN 
    Select 
        RowNo, FirstName, LastName 
       From 
        (
         Select Row_Number()Over(Order By Id) As [RowNo], 
          FirstName, 
          LastName  
         From Users     
        ) tblTemp 
       Where RowNo > @Skip And RowNo <= @Take + @Skip 

       Set @TotalRows = ??? -- I need the number of total rows after applying paging. How can I do this? 
    END

您可以使用@@ROWCOUNT

程序

CREATE PROCEDURE Search 
    @Take  Int   = 10, 
    @Skip  Int   = 0, 
    @TotalRows Int Out 
AS 
BEGIN 
    Select 
     RowNo, 
     FirstName, 
     LastName 
    From (
     Select 
      Row_Number()Over(Order By Id) As [RowNo], 
      FirstName, 
      LastName  
     From Users     
    ) tblTemp 
    Where RowNo > @Skip And RowNo <= @Take + @Skip 

    Set @TotalRows = @@ROWCOUNT 
END 

您可以撥打PROC等;

declare @total_rows int; 
exec search 10, 0, @total_rows output 
select @total_rows
