我该如何在SQL中获得以下输出？

Question

我有两个表Employee和Grade，想要输出像第三个表（即输出表）？  如果可能的话怎么样？

Answer 1

你可以试试这个

select e.name , g.grade 
from employeetable e, gradetable g 
where  e.salary >= g.min 
and  e.salary <= g.max 

Answer 2

试试这个

SELECT 
  E.Name
  ,(SELECT G.Grade FROM Grade G WHERE E.Salary BETWEEN G.Min AND G.Max) 
FROM  Employee E
