如何合并两个选择和两个where子句？

Question

表一：

StudentId,  StudentName,  School
1           Sam            ABC

表二：

StudentCity  StudentId
Paris         1
mexico        2

答案应为“ Paris”，因为StudentId为1

select StudentCity 
from TWO
where StudentId = (select StudentId from ONE where StudentName="SAM"); 

请建议我进行SQL查询。

Answer 1

select StudentCity from TWO 
inner join ONE on ONE.StudentId = TWO.StudentId
where ONE.StudentName= "SAM"
