2020年3月14日 - 计算机数据

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

本代码适用于MsSql2000,对于其它数据库也可用.但没必要 –创建存储过程
CREATE PROCEDURE pagination @tblName varchar(255), — 表名 @strGetFields

排序的字段名(可包含如TABLE.FLDNAME形式) @PageSize int = 10, — 页尺寸
@PageIndex int = 1, — 页码 @doCount bit = 0, — 返回记录总数, 非 0
值则返回 @OrderType bit = 0, — 设置排序类型, 非 0 值则降序 @strWhere

varchar(5000) — 主语句 declare @strTmp varchar(110) — 临时变量 declare
@strOrder varchar(400) — 排序类型 declare @fldName_t varchar(255) —
在分页时用的排序字段名,不包含多表并列时的表名 set @fldName_t =
right(@fldName,len(@fldName)-CHARINDEX(‘.’,@fldName)) if @doCount != 0

DECLARE @strOrderType varchar(1000)        –排序类型语句 (order by
column asc或者order by column desc)
