T-SQL: Paging with ROW_NUMBER()
In MSSQL 2000 we used to do paging either by dynamic sql or by some advanced techniques like the example with rowcount. In MSSQL 2005 with the introduction of ROW_NUMBER function life is a lot easier.
DECLARE @PageNum AS INT;
DECLARE @PageSize AS INT;
SET @PageNum = 2;
SET @PageSize = 10;
WITH OrdersRN AS
(
SELECT ROW_NUMBER() OVER(ORDER BY OrderDate, OrderID) AS RowNum
,OrderID
,OrderDate
,CustomerID
,EmployeeID
FROM dbo.Orders
)
SELECT *
FROM OrdersRN
WHERE RowNum BETWEEN (@PageNum - 1) * @PageSize + 1
AND @PageNum * @PageSize
ORDER BY OrderDate
,OrderID;
