Answer 1

MySQL 不支持 EXCEPT 运算符，但您可以执行以下操作：

SELECT * FROM TableA WHERE mohonID NOT IN(SELECT mohonID FROM TableB)

Answer 2

Here is one way of doing it

select tablea.*
from tablea a
left join tableb b
  on a.mohonID=b.mohonID and a.nama=b.nama
where b.mohonID is null

and here is another

select tablea.*
from tablea a
where not exists(
  select * 
  from tableb b 
  where a.mohonID=b.mohonID and a.nama=b.nama)
