关于SQL SERVER问题,急求?
现在我查询出某个字段可能有多条记录,我想把这些记录串联起来,用“/”分开,如何实现?
------解决方案--------------------declare @a varchar(1000) 
 select @a=coalesce(@a+ '/ ', ' ')+ltrim([Field]) from [Table] 
 select @a 
------解决方案--------------------Create Function F_GetRole(@ID Int) 
 Returns Nvarchar(2000) 
 As 
 Begin 
 Declare @S Nvarchar(2000) 
 Select @S =  ' ' 
 Select @S = @S +  '/ ' + Role From B Where ID = @ID 
 Select @S = Stuff(@S, 1, 1,  ' ') 
 Return @S 
 End 
 GO 
 Select 
 ID, 
 Name, 
 dbo.F_GetRole(ID) As Role 
 From 
 A 
 GO
------解决方案--------------------create table t(id varchar(10)) 
 insert into t 
 select  'aaa ' union all 
 select  'dddd ' union all 
 select  'cccc ' 
 select * from t 
 ---联结所有的ID 
 declare @str varchar(200) 
 select @str= ' ' 
 select @str=@str + ID +  '/ ' from t 
 select left(ltrim(@str),len(ltrim(@str))-1)   
 --drop table t
------解决方案--------------------create table # 
 ( 
 	a int, 
 	b varchar(10) 
 )   
 insert into # 
 select 1, 'aaaa ' union all 
 select 2, 'bbbb ' union all 
 select 3, 'cccc ' union all 
 select 4, 'dddd ' union all 
 select 5, 'eeee ' union all 
 select 6, 'ffff '     
 select * 
 from #   
 --进行拼接 
 declare @str varchar(100) 
 set @str= ' '   
 select @str=@str+b+ '/ ' from # 
 select  left(@str,len(@str)-1) as 结果   
 drop table #   
 运行后:
