sql server2000 里面怎么实现oracle10g的 wmsys.wm_concat 的功能

-------合并表-------/****************************************************************************************************************************************************** 合并分拆表数据 整理人：中国风(Roy) 日期:2008.06.06 ******************************************************************************************************************************************************/ --> --> (Roy)生成測試數據 if not object_id('Tab') is null     drop table Tab Go Create table Tab([Col1] int,[Col2] nvarchar(1)) Insert Tab select 1,N'a' union all select 1,N'b' union all select 1,N'c' union all select 2,N'd' union all select 2,N'e' union all select 3,N'f' Go 合并表: SQL2000用函数: go if object_id('F_Str') is not null     drop function F_Str go create function F_Str(@Col1 int) returns nvarchar(100) as begin     declare @S nvarchar(100)     select @S=isnull(@S+',','')+Col2 from Tab where [email protected]     return @S end go Select distinct Col1,Col2=dbo.F_Str(Col1) from Tab go SQL2005用XML: 方法1: select     a.Col1,Col2=stuff(b.Col2.value('/R[1]','nvarchar(max)'),1,1,'') from     (select distinct COl1 from Tab) a Cross apply     (select COl2=(select N','+Col2 from Tab where Col1=a.COl1 For XML PATH(''), ROOT('R'), TYPE))b 方法2: select     a.Col1,COl2=replace(b.Col2.value('/Tab[1]','nvarchar(max)'),char(44)+char(32),char(44)) from     (select distinct COl1 from Tab) a cross apply     (select Col2=(select COl2 from Tab  where COl1=a.COl1 FOR XML AUTO, TYPE)                 .query(' <Tab>                 {for $i in /Tab[position() <last()][email protected] return concat(string($i),",")}                 {concat("",string(/Tab[last()][email protected]))}                 </Tab>')                 )b SQL05用CTE: ;with roy as(select Col1,Col2,row=row_number()over(partition by COl1 order by COl1) from Tab) ,Roy2 as (select COl1,cast(COl2 as nvarchar(100))COl2,row from Roy where row=1 union all select a.Col1,cast(b.COl2+','+a.COl2 as nvarchar(100)),a.row from Roy a join Roy2 b on a.COl1=b.COl1 and a.row=b.row+1) select Col1,Col2 from Roy2 a where row=(select max(row) from roy where Col1=a.COl1) order by Col1 option (MAXRECURSION 0) 生成结果: /* Col1        COl2 ----------- ------------ 1          a,b,c 2          d,e 3          f (3 行受影响) */
