–分页存储过程示例

Alter PROCEDURE [dbo].[JH_PageDemo]

@pageSize int = 9000000000,

@pageIndex int = 1 ,

@orderBy Nvarchar(200) = ” — 不加order By

AS

SET NOCOUNT ON

–声明变量

DECLARE @select VARCHAR(3048);

DECLARE @from VARCHAR(512);

DECLARE @RowNumber VARCHAR(256);

DECLARE @condition nVARCHAR(3990);

DECLARE @groupBy varchar(50);

DECLARE @sql VARCHAR(3998);

DECLARE @RowStartIndex INT;

DECLARE @RowEndIndex INT;

BEGIN

SET NOCOUNT on

IF @orderBy <> ”

Set @orderBy = ‘ ORDER BY ‘ + @orderBy;

else

Set @orderBy = ‘ ORDER BY Userid ‘ ;

SET @select = ‘ select userid,username ,’;

–设置排序语句

SET @RowNumber =’ROW_NUMBER() OVER (‘ + @orderBy + ‘ ) as RowNumber ‘;

SET @select = @select + @RowNumber;

SET @from = ‘ FROM users ‘;

–设置条件语句@GULevel

SET @condition = ‘ WHERE 1=1 ‘;

SET @condition = @condition + ‘AND userid > 0’;

–分组语句

SET @groupBy = ‘ GROUP BY USerID ‘

SET @RowStartIndex = ( @pageIndex -1) * @pageSize + 1

SET @RowEndIndex = @pageIndex * @pageSize ;

–查询结果

SET @sql = ‘SET NOCOUNT ON;

WITH ResultTable AS ( ‘ + @select + @from + @condition +’)

SELECT * FROM ResultTable WHERE RowNumber between ‘ +

Cast(@RowStartIndex AS VARCHAR(32)) + ‘ AND ‘ + CAST(@RowEndIndex AS VARCHAR(32))

+ ‘ ; SELECT count(*) as totalcount ‘ + @from + @condition + ‘ ‘

–PRINT @sql;

EXEC(@sql);
