SQL?server 分页步骤小结

这里面介绍一下常用的分页方法：

1.使用top来分页

select top @pageSize * from table where id not in (select top @pageSize*(@pageIndex-1) id from table)

2.使用 ROW_NUMBER()OVER?

SELECT * FROM (SELECT ROW_NUMBER() OVER (order by T.字段名 desc )AS Row, T.*  from 表名 T  WHERE 条件 ) TT WHERE TT.Row between 起始位置  and 结束位置; StringBuilder strSql = new StringBuilder();            strSql.Append("SELECT * FROM ( ");            strSql.Append(" SELECT ROW_NUMBER() OVER (");            if (!string.IsNullOrWhiteSpace(orderby.Trim()))            {                strSql.Append("order by T." + orderby);            }            else            {                strSql.Append("order by T.ID desc");            }            strSql.Append(")AS Row, T.*  from TableName T ");            if (!string.IsNullOrWhiteSpace(strWhere.Trim()))            {                strSql.Append(" WHERE " + strWhere);            }            strSql.Append(" ) TT");            strSql.AppendFormat(" WHERE TT.Row between {0} and {1}", startIndex, endIndex);

?3.使用分页存储过程

if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[sys_Page_v2]') and OBJECTPROPERTY(id, N'IsProcedure') = 1)drop procedure [dbo].[sys_Page_v2]GOCREATE PROCEDURE [dbo].[sys_Page_v2]@PCount int output,    --总页数输出@RCount int output,    --总记录数输出@sys_Table nvarchar(100),    --查询表名@sys_Key varchar(50),        --主键@sys_Fields nvarchar(500),    --查询字段@sys_Where nvarchar(3000),    --查询条件@sys_Order nvarchar(100),    --排序字段@sys_Begin int,        --开始位置@sys_PageIndex int,        --当前页数@sys_PageSize int        --页大小ASSET NOCOUNT ONSET ANSI_WARNINGS ONIF @sys_PageSize < 0 OR @sys_PageIndex < 0BEGIN        RETURNENDDECLARE @new_where1 NVARCHAR(3000)DECLARE @new_order1 NVARCHAR(100)DECLARE @new_order2 NVARCHAR(100)DECLARE @Sql NVARCHAR(4000)DECLARE @SqlCount NVARCHAR(4000)DECLARE @Top intif(@sys_Begin <=0)    set @sys_Begin=0else    set @[email protected]_Begin-1IF ISNULL(@sys_Where,'') = ''    SET @new_where1 = ' 'ELSE    SET @new_where1 = ' WHERE ' + @sys_Where IF ISNULL(@sys_Order,'') <> '' BEGIN    SET @new_order1 = ' ORDER BY ' + Replace(@sys_Order,'desc','')    SET @new_order1 = Replace(@new_order1,'asc','desc')    SET @new_order2 = ' ORDER BY ' + @sys_OrderENDELSEBEGIN    SET @new_order1 = ' ORDER BY ID DESC'    SET @new_order2 = ' ORDER BY ID ASC'ENDSET @SqlCount = 'SELECT @RCount=COUNT(1),@PCount=CEILING((COUNT(1)+0.0)/'            + CAST(@sys_PageSize AS NVARCHAR)+') FROM ' + @sys_Table + @new_where1EXEC SP_EXECUTESQL @SqlCount,[email protected] INT OUTPUT,@PCount INT OUTPUT',               @RCount OUTPUT,@PCount OUTPUTIF @sys_PageIndex > CEILING((@RCount+0.0)[email protected]_PageSize)    --如果输入的当前页数大于实际总页数,则把实际总页数赋值给当前页数BEGIN    SET @sys_PageIndex =  CEILING((@RCount+0.0)[email protected]_PageSize)ENDset @sql = 'select '+ @sys_fields +' from ' + @sys_Table + ' w1 '    + ' where '+ @sys_Key +' in ('        +'select top '+ ltrim(str(@sys_PageSize)) +' ' + @sys_Key + ' from '        +'('            +'select top ' + ltrim(STR(@sys_PageSize * @sys_PageIndex + @sys_Begin)) + ' ' + @sys_Key + ' FROM '         + @sys_Table + @new_where1 + @new_order2         +') w ' + @new_order1    +') ' + @new_order2print(@sql)Exec(@sql)GO
