--创建测试数据 create table #a(id int,name varchar(10)) insert into #a values(1,'A') insert into #a values(2,'B') insert into #a values(3,'C')
create table #b(id1 int,id2 int) insert into #b values(1,2) insert into #b values(2,1) insert into #b values(2,3)
---------------实现代码部分---------------- select t1.name as name1 ,t2.name as name2 from #b tt left join #a t1 on tt.id1 =t1.id left join #a t2 on tt.id2 =t2.id
