使用存储过程实现分页查询,SQL语句如下:

USE [DatebaseName]--数据库名GO/****** Object:StoredProcedure [dbo].[Pagination]Script Date: 03/30/2019 10:36:52 ******/SET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOCreate PROCEDURE [dbo].[Pagination](@SqlTable varchar(1000),--要查询的表或视图,也可以一句sql语句@SqlPK varchar(50),--主键@SqlField varchar(1000),--查询的字段@SqlWhere varchar(1000)='', --查询条件 @SqlOrder varchar(200),--排序@PageSize int=20,--每页的记录数@PageIndex int=1, --第几页,默认第一页@IsCount bit, --是否获取记录数@RecordCount int=0 output)ASSET NOCOUNT ONDECLARE @PageLowerBound intDECLARE @PageUpperBound intDECLARE @sqlstr nvarchar(2000)--获取记录数IF @IsCount=1BEGINSET @sqlstr=N'select @sCount=count(1) FROM '+@SqlTable+' WHERE 1=1 '+@SqlWhereExec sp_executesql @sqlstr,N'@sCount int outPut',@RecordCount OUTPUTENDSET @PageLowerBound=(@PageIndex-1)*@PageSizeSET @PageUpperBound=@PageLowerBound+@PageSizeCREATE TABLE #pageindex(id int identity(1,1) not null,nid varchar(100))SET rowcount @PageUpperBound SET @sqlstr=N'insert into #pageindex(nid) select '+@SqlPK+' from '+@SqlTable+' where 1=1 '+@SqlWhere+' '+@SqlOrderExec sp_executesql @sqlstrSET @sqlstr='select '+@SqlField+' FROM '+ @SqlTable +' inner join #pageindex p on '+@SqlPK+'=p.nid and (p.id>'+STR(@PageLowerBound)+') and (p.id<='+STR(@PageUpperBound)+')' +' '+@SqlOrderExec sp_executesql @sqlstrSET NOCOUNT OFFDROP TABLE #pageindex

但是如果你有一些奇怪的需求,比如删除当前页数据之后不重新返回第一页,然后继续请求下一页,这时会出现有一下数据被跳过查询

解决方案如下:

USE [DatebaseName]GO/****** Object:StoredProcedure [dbo].[Pagination]Script Date: 03/30/2019 14:41:39 ******/SET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOCREATE PROCEDURE [dbo].[PaginationSkip](@SqlTable varchar(1000),--要查询的表或视图,也可以一句sql语句@SqlPK varchar(50),--主键@SqlField varchar(1000),--查询的字段@SqlWhere varchar(1000)='', --查询条件 @SqlOrder varchar(200),--排序@PageSize int=20,--每页的记录数@PageIndex int=1, --第几页,默认第一页@IsCount bit, --是否获取记录数@RecordCount int=0 output,@Skip int=0 --跳过记录数)ASSET NOCOUNT ONDECLARE @PageLowerBound intDECLARE @PageUpperBound intDECLARE @sqlstr nvarchar(2000)--获取记录数IF @IsCount=1BEGINSET @sqlstr=N'select @sCount=count(1) FROM '+@SqlTable+' WHERE 1=1 '+@SqlWhereExec sp_executesql @sqlstr,N'@sCount int outPut',@RecordCount OUTPUTENDSET @PageLowerBound=(@PageIndex-1)*@PageSize-@Skip--减去删除的条数,以适应需求SET @PageUpperBound=@PageLowerBound+@PageSize-@Skip CREATE TABLE #pageindex(id int identity(1,1) not null,nid varchar(100))SET rowcount @PageUpperBound SET @sqlstr=N'insert into #pageindex(nid) select '+@SqlPK+' from '+@SqlTable+' where 1=1 '+@SqlWhere+' '+@SqlOrderExec sp_executesql @sqlstrSET @sqlstr='select '+@SqlField+' FROM '+ @SqlTable +' inner join #pageindex p on '+@SqlPK+'=p.nid and (p.id>'+STR(@PageLowerBound)+') and (p.id<='+STR(@PageUpperBound)+')' +' '+@SqlOrderExec sp_executesql @sqlstrSET NOCOUNT OFFDROP TABLE #pageindexGO

添加了一个 Skip 参数,来指示需要往前推进几条数据,这个参数就是你在请求之前删除的条数
