我應該如何在SQL中獲得以下輸出？

Question

我有兩個表Employee和Grade，想要一個像第三個表（即輸出表）的輸出嗎？ 如果它可能那麼如何？

Answer 1

你可以試試這個

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

Answer 2

試試這個

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