SQL 三张表联合查询其中表有空字段的问题

Question

table1(id1)、table2(id2,id1,no)、table3(no,name)

select t3.name from table1 t1(nolock) inner join table2 t2(nolock)
on t1.id1 = t2.id1
inner join table3 t3(nolock)
on t2.no = t3.no

第2张表里面对应的no字段有可能为空，为空的时候name就为空，这个要怎么查询才不会有冗余，请指教

Answer 1

table1(id1)、table2(id2,id1,no)、table3(no,name)

select t3.name from table1 t1(nolock) inner join table2 t2(nolock)
on t1.id1 = t2.id1
inner join table3 t3(nolock)
on t2.no = isnull(t3.no,'')
