一个基于ROW_NUMBER()的通用分页存储过程代码

建立好如下的存储过程，以后要分页，直接调用改存储过程就可以了。
注意：数据量大、性能要求高的，请个性化处理。

ALTER PROCEDURE [dbo].[COMMON_PROCEDURE_SelectWithPage]
@Sql VARCHAR(5000),
@CurrentPageNo INT,
@PageSize INT,
@TotalNum INT OUTPUT
AS
SET NOCOUNT ON
DECLARE @SqlCmd VARCHAR(5000)
------------------------------------------ --查询数据
SET @SqlCmd = 'SELECT * FROM (' + @Sql + ') A WHERE RowIndex BETWEEN ' + CONVERT(VARCHAR,(@CurrentPageNo-1) * @PageSize + 1) + ' AND ' + CONVERT(VARCHAR,@CurrentPageNo * @PageSize)
EXEC(@SqlCmd) PRINT (@SqlCmd)
------------------------------------------ --求记录总数
IF @TotalNum = -1
BEGIN
CREATE TABLE #Temp1(num INT)
INSERT INTO #Temp1
EXEC('SELECT count(*) FROM (' + @Sql + ') A')
SELECT @TotalNum=(SELECT * FROM #Temp1)
DROP TABLE #Temp1
END

用法很简单，但必须在传入的SQL中使用ROW_NUMBER() OVER(...) AS RowIndex ：
DECLARE @Sql VARCHAR(5000)
DECLARE @CurrentPageNo INT
DECLARE @PageSize INT
DECLARE @TotalNum INT

SET @CurrentPageNo = 100
SET @PageSize = 10
SET @TotalNum = -1
SET @Sql = ' SELECT *, ROW_NUMBER() OVER (ORDER BY 排序字段) AS RowIndex FROM 表名 A WITH (NOLOCK) '

EXEC [dbo].[COMMON_PROCEDURE_SelectWithPage] @Sql,@CurrentPageNo,@PageSize,@TotalNum OUTPUT

SELECT @TotalNum
