Question

我有下表

Id     Name      member
1,2,3  Ab,Xy,Pq  member1
8,9    De,Fg     member2

我想在sql server 2008中使用如下的临时表

Id  Name  member
1   Ab    member1
2   Xy    member1
3   Pq    member1
8   De    member2
9   Fg    member1

编辑：请检查我的表有两列逗号分隔值，对于那些值，我需要在最后一个表中显示结果。 1表示Ab，2表示Xy，依此类推。

尝试以下查询

    declare @t table (id varchar(20),name varchar(20),member varchar(20))
    insert into @t (id,Name,member) values 
    ('1,2,3',  'Ab,Xy,Pq',  'member1'),
    ('8,9' ,   'De,Fg'  ,   'member2')


;with t as (select row_number() over (order by member) r, t.member,a.b.value('.','varchar(10)') n from
    (select member, cast('<t>'+ replace(id,',','</t><t>')+'</t>' as xml) as  id,cast('<t>'+ replace(name,',','</t><t>')+'</t>' as xml) as nme from @t) t
    cross apply id.nodes('/t') a(b) ),
t1 as (select row_number() over (order by member) r,a.b.value('.','varchar(10)') n1 from 
    (select member, cast('<t>'+ replace(id,',','</t><t>')+'</t>' as xml) as  id,cast('<t>'+ replace(name,',','</t><t>')+'</t>' as xml) as nme from @t) t
    cross apply nme.nodes('/t') a(b))

select t.member,t.n,t1.n1 from t inner join t1 on t.r=t1.r

将逗号分隔值拆分为sql server中的列
