我的查询

select * from t1 A
full outer join t2 B
on A.id=B.id

where not exists(select A.name intersect B.name);

Answer 1

您需要使用coalesce()进行过滤：

select coalesce(t.id, t1.id) as unmatched_ids
from t full outer join
     t1
     on t1.id = t.id
where (t.id is null or t1.id is null);

Answer 2

早上好，请尝试以下代码。

请注意例如[Name] = ajay，ravi，raja

SELECT A.*,
B.*
from t1 [A]
FULL JOIN t2 [B]
WHERE A.id=B.id
AND A.[Name]<>B.[Name]

希望这会有所帮助，谢谢
