MYSQL內部聯接，但具有多個列

Question

SELECT * FROM people p INNER JOIN job j ON p.job_id = j.id ORDER BY j.id ASC 

以上就是如何我使用Inner Join添加j.id到p.job_id，但如果我想補充j.description到j.job_description什麼？

我已經試過

SELECT * FROM people p INNER JOIN job j ON p.job_id = j.id INNER JOIN job j ON p.job_desc = j.description ORDER BY j.id ASC 

但這不起作用。

的想法是從我的表job添加內容到表people

Answer 1

如果我理解你的權利，這必須是解決方案：

SELECT * 
FROM people p INNER JOIN job j ON p.job_id = j.id and p.job_desc = j.description 
ORDER BY j.id ASC
