如何在MYSQL中基于项目id从两个表中获取所有记录

人桌

 id project_id comp_id  people_name
    1   13         1        john
    2   16         2        rob
    3   18         1        jack
    4   18         2        lee

公司表

 id project_id comp_name
    1   21         axn
    2   13         ibm 
    3   15         anz

尝试内部连接

SELECT P.*,C.* 
FROM people_table P 
INNER JOIN company_table C ON P.project_id = C.project_id
WHERE P.project_id = $your_project_id;

您需要这个：

您应该检查SQLFIDLE:

试试下面的内容

SELECT A.*,B.* 
FROM people_table as A 
INNER JOIN company_table as B 
ON A.project_id = B.project_id

select * from people_table p,company_table c where p.projectID=c.projectID

---

这将显示两次“项目ID”列。因此，您可以使用distinct关键字来获取一个项目id列。

如果可以，请告诉我结果，如
