一篇好用的通用分页存储过程,可以用在任何开发上哦,只要小小的改动就好了,有需要的朋友可以参考一下本款实例。 代码如下复制代码 /*通用分页存储过程*/USE HotelManagementSystemGOIF EXISTS(SELECT * FROM sys.objects WHERE NAME='cndoup_GetPageOfRecords')DROP PROCEDURE cndoup_GetPageOfRecordsGO--创建存储过程CREATE PROCEDURE cndoup_GetPageOfRecords@pageSize int = 20, --分页大小@currentPage int , --第几页@columns varchar(1000) = '*', --需要得到的字段 @tableName varchar(100), --需要查询的表 @condition varchar(1000) = '', --查询条件, 不用加where关键字@ascColumn varchar(100) = '', --排序的字段名 (即 order by column asc/desc)@bitOrderType bit = 0, --排序的类型 (0为升序,1为降序)@pkColumn varchar(50) = '' --主键名称ASBEGIN --存储过程开始DECLARE @strTemp varchar(300)DECLARE @strSql varchar(5000) --该存储过程最后执行的语句DECLARE @strOrderType varchar(1000) --排序类型语句 (order by column asc或者order by column desc)BEGINIF @bitOrderType = 1 --降序BEGINSET @strOrderType = ' ORDER BY '+@ascColumn+' DESC'SET @strTemp = '(SELECT min'ENDELSE--升序BEGINSET @strOrderType = ' ORDER BY '+@ascColumn+' ASC'SET @strTemp = '(SELECT max'ENDIF @currentPage = 1--第一页BEGINIF @condition != ''SET @strSql = 'SELECT TOP '+STR(@pageSize)+' '+@columns+' FROM '+@tableName+' WHERE '+@condition+@strOrderTypeELSESET @strSql = 'SELECT TOP '+STR(@pageSize)+' '+@columns+' FROM '+@tableName+@strOrderTypeENDELSE-- 其他页BEGINIF @condition !=''SET @strSql = 'SELECT TOP '+STR(@pageSize)+' '+@columns+' FROM '+@tableName+' WHERE '+@condition+' AND '+@pkColumn+@strTemp+'('+@pkColumn+')'+' FROM (SELECT TOP '+STR((@currentPage-1)*@pageSize)+' '+@pkColumn+' FROM '+@tableName+'where'+@condition+@strOrderType+') AS TabTemp)'+@strOrderTypeELSESET @strSql = 'SELECT TOP '+STR(@pageSize)+' '+@columns+' FROM '+@tableName+' WHERE '+@pkColumn+@strTemp+'('+@pkColumn+')'+' FROM (SELECT TOP '+STR((@currentPage-1)*@pageSize)+' '+@pkColumn+' FROM '+@tableName+@strOrderType+') AS TabTemp)'+@strOrderTypeENDENDEXEC (@strSql)END--存储过程结束--分页得到客房信息列表测试EXEC cndoup_GetPageOfRecords 20,2,'房间号=RoomNum,房间状态=(SELECT RoomTypeDes FROM RoomType WHERE RoomTypeID=Room.RoomTypeID),房间状态=(SELECT RSDec FROM RoomStatus WHERE RoomStatusID=Room.RoomStatusID),床位数=BedNum,楼层=Floors,描述=RoomDes,备注=RoomRemark','Room','','RoomID',0,'RoomID'--根据房间号得到客房信息测试EXEC cndoup_GetPageOfRecords 1,1,'房间号=RoomNum,房间状态=(SELECT RoomTypeDes FROM RoomType WHERE RoomTypeID=Room.RoomTypeID),房间状态=(SELECT RSDec FROM RoomStatus WHERE RoomStatusID=Room.RoomStatusID),BedNum,Floors,RoomDes,RoomRemark','Room','RoomNum=304','RoomID',0,'RoomID'
