How to do pagination in SQL Server 2008
You can use ROW_NUMBER():
Returns the sequential number of a row within a partition of a result set, starting at 1 for the first row in each partition.
Example:
WITH CTEResults AS
(
SELECT IDColumn, SomeField, DateField, ROW_NUMBER() OVER (ORDER BY DateField) AS RowNum
FROM MyTable
)
SELECT *
FROM CTEResults
WHERE RowNum BETWEEN 10 AND 20;
You can try something like
DECLARE @Table TABLE(
Val VARCHAR(50)
)
DECLARE @PageSize INT,
@Page INT
SELECT @PageSize = 10,
@Page = 2
;WITH PageNumbers AS(
SELECT Val,
ROW_NUMBER() OVER(ORDER BY Val) ID
FROM @Table
)
SELECT *
FROM PageNumbers
WHERE ID BETWEEN ((@Page - 1) * @PageSize + 1)
AND (@Page * @PageSize)
SQL Server 2012 provides pagination functionality (see http://www.codeproject.com/Articles/442503/New-features-for-database-developers-in-SQL-Server)
In SQL2008 you can do it this way:
declare @rowsPerPage as bigint;
declare @pageNum as bigint;
set @rowsPerPage=25;
set @pageNum=10;
With SQLPaging As (
Select Top(@rowsPerPage * @pageNum) ROW_NUMBER() OVER (ORDER BY ID asc)
as resultNum, *
FROM Employee )
select * from SQLPaging with (nolock) where resultNum > ((@pageNum - 1) * @rowsPerPage)
Prooven! It works and scales consistently.
1) CREATE DUMMY DATA
CREATE TABLE #employee (EMPID INT IDENTITY, NAME VARCHAR(20))
DECLARE @id INT = 1
WHILE @id < 200
BEGIN
INSERT INTO #employee ( NAME ) VALUES ('employee_' + CAST(@id AS VARCHAR) )
SET @id = @id + 1
END
2) NOW APPLY THE SOLUTION.
This case assumes EMPID to be unique and sorted column.
Off-course, you will apply it a different column...
DECLARE @pageSize INT = 20
SELECT * FROM (
SELECT *, PageNumber = CEILING(CAST(EMPID AS FLOAT)/@pageSize)
FROM #employee
) MyQuery
WHERE MyQuery.PageNumber = 1
