在SQL Server中使用JOIN排除记录

Question

我有3张桌子，

表MEmployee

ID Name
1  Andy
2  Donny
3  Mark
4  John

餐篮

ID Name
1  Andy

表格正在运行

ID Name
2  Donny

我想从MEmployee中创建Soccer table，但不包括Basket table和Running。这样的结果

桌上足球

ID Name
3  Mark
4  John

我的查询不起作用：

SELECT * FROM MEmployee A
INNER JOIN Basket B On A.ID = B.ID
INNER JOIN Running C ON A.ID = C.ID
WHERE A.ID <> B.ID AND A.ID = C.ID

Answer 1

我们可以在此处尝试使用EXCEPT

SELECT Name FROM MEmployee
EXCEPT
SELECT Name FROM Basket
EXCEPT
SELECT Name FROM Running;

Demo

Answer 2

您可以将NOT EXISTS与CTE结合使用：

with t as (
     select id, name
     from Basket
     union all
     select id, name
     from Running
)

select e.*
from MEmployee e
where not exists (select 1 from t where t.id = e.id);
