Better way for Getting Total Count along with Paging in SQL Server 2012

Question

I have requirement to get the total count of records along with paging. At present I am doing it as listed below in SQL Server 2012. This needs a separate query for getting count. Is there any improved way in SQL Server 2012?

ALTER PROCEDURE dbo.tpGetPageRecords (     @OffSetRowNo INT,          @FetchRowNo INT,     @TotalCount INT OUT )  AS   SELECT CSTNO, CSTABBR  FROM DBATABC WHERE CSTABBR LIKE 'A%' ORDER BY CSTNO OFFSET ( @OffSetRowNo-1 ) * @FetchRowNo ROWS FETCH NEXT @FetchRowNo ROWS ONLY  SET @TotalCount =  (SELECT COUNT(*) FROM DBATABC WHERE CSTABBR LIKE 'A%')   GO 

Answer 1

If we're allowed to change the contract, you can have:

SELECT CSTNO, CSTABBR,COUNT(*) OVER () as TotalCount FROM DBATABC WHERE CSTABBR LIKE 'A%' ORDER BY CSTNO OFFSET ( @OffSetRowNo-1 ) * @FetchRowNo ROWS FETCH NEXT @FetchRowNo ROWS ONLY 

And now the total will be available as a separate column in the result set. Unfortunately, there's no way to assign this value to a variable in this same statement, so we can no longer provide it as an OUT parameter.

This uses the OVER clause (available since 2005) to allow an aggregate to be computed over the entire (unlimited) result set and without requiring GROUPing.

WITH Data_CTE  AS (     SELECT [name], object_id     FROM sys.all_objects     --WHERE [name] LIKE 'fn_%' ),  Count_CTE  AS  (     SELECT COUNT(*) AS TotalRows FROM Data_CTE ) SELECT * FROM Data_CTE CROSS JOIN Count_CTE ORDER BY [name] OFFSET (@PageNum - 1) * @PageSize ROWS FETCH NEXT @PageSize ROWS ONLY;
