10/2/2015·1 min read

This is old way, there's better way to do it, but kind of sampel example of how to do pagination at sql level

declare @requestMaxReturnItems int
declare @requestPageNumber int
declare @startRow int
declare @endRow int
declare @totalPageByMaxReturnNumber int
declare @totalCount int;

-- temp test

-- request from ui
-- max items return from this sql
set @requestMaxReturnItems = 10;
-- which page number to return
set @requestPageNumber = 1
--set @startRow = 1
--set @endRow = 10

select @totalCount = count(*) FROM [OrangeGrid].[dbo].[DiagnosticLog];
set @totalPageByMaxReturnNumber = @totalCount / @requestMaxReturnItems;
set @startRow = (@requestPageNumber - 1) * @requestMaxReturnItems;
set @endRow = @requestPageNumber * @requestMaxReturnItems;

print @totalPageByMaxReturnNumber

SELECT  *
FROM    ( SELECT    ROW_NUMBER() OVER ( ORDER BY YourTable.CreateDate desc ) AS RowNum, *
          FROM      YourTable
        ) AS t
WHERE   RowNum > @startRow
    AND RowNum <= @endRow
ORDER BY RowNum
