Sum in ROW_NUMBERを計算する方法

Question

私を助けてください。ここで私は、ユーザーがアラート

ALTER PROCEDURE CustPaginantion (@PageNum int,@TotalPages int) 
AS 
BEGIN 
    SELECT ROW_NUMBER() OVER (ORDER BY CustId) AS UNIQID, 
      COUNT(*) OVER(ORDER BY CustId) AS cnt, 
      CustId, 
      CustName, 
      CustAddress 
    FROM Customer 
    ORDER BY UNIQID 
    OFFSET (@PageNum-1)*@TotalPages ROWS 
    FETCH NEXT @TotalPages ROWS ONLY 
END 

Answer 1

SELECT ROW_NUMBER() OVER (ORDER BY CustId) AS UNIQID, 
     COUNT(*) OVER(ORDER BY CustId) AS cnt, 
     CustId, 
     CustName, 
     CustAddress 
FROM Customer 
ORDER BY UNIQID 
OFFSET (@PageNum-1)*@TotalPages ROWS 
FETCH NEXT @TotalPages ROWS ONLY 

IF @@ROWCOUNT > @TotalPages 
    RAISERROR(' user enters more than the total rows',1,1) 

を通じて、その後、総行以上を入力した場合に改ページを行いたい
