项目中有很多小型的表(数据量不大),都需要实现分页查询,因此实现了一个通用的分页。
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。
(责任编辑:admin)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 |
