SqlServer中使用row_number() over实现通用的分页存储过程

--通用的分页存储过程

create procedure sp_pager

(

@Sql nvarchar(4000), --要分页的sql语句

@CurrentPageNo int, --当前页面索引

@PageSize int, --每一页要显示的页数

@TotalNum int output --数据的总条数 (输出参数)

)

as

　　declare @sqlcmd varchar(8000)

　　--查询数据

　　set @sqlcmd = 'select * from (' + @Sql + ') a where RowIndex between ' + convert(nvarchar,(@CurrentPageNo-1) * @PageSize + 1) + ' and ' + convert(varchar,@CurrentPageNo * @PageSize)

　　exec(@sqlcmd)

　　print (@sqlCmd)

　　--求记录总数

create table tempTable(num int)

　　insert into tempTable exec('select count(*) from (' + @Sql + ') a')

　　select @TotalNum=(select * from tempTable)

　　drop table tempTable

go

--=========================================测试存储过程

declare @Sql varchar(5000)

declare @CurrentPageNo int

declare @PageSize int

declare @TotalNum int

set @CurrentPageNo = 2

set @PageSize = 4

set @Sql=' select products.PID,products.PName,products.MarketPrice,productDispose.ShopPrice,row_number() over (order by products.PID) as RowIndex from ProductsDisposeInfo productDispose inner join ProductsInfo products on productDispose.PID=products.PID'

exec sp_pager @Sql,@CurrentPageNo,@PageSize,@TotalNum output

print @TotalNum
