的MySQL连接两个talbles

Question

我讨厌要求代码，但我似乎无法做到以下 -

员工

| lastname - name - position | 
    | Henderson | John | A  | 
    | Howard | Bob  | B  | 
    | Hendry | Chris | B  | 

Max_person

| lastname - change | 
    | Henderson | John | 
    | Howard | Bob  | 
    | Hendry | Chris | 

我一直在试图加入这两个表格 - 将员工的“职位”列添加到max_person的末尾。

什么是查询在这里使用？

Answer 1

用途：

SELECT mp.*, 
     s.position 
    FROM MAX_PERSON mp 
    JOIN STAFF s ON s.name = mp.change 
       AND s.lastname = mp.lastname 

Answer 2

select mp.lastname, mp.change, s.position 
from Staff s 
inner join Max_person mp on s.lastname = mp.lastname 
    and s.name = mp.change
