MySQL查询在两个表中

Question

可以获得名称=＆＃34; A＆＃34; AND status = 1？名称在表项中，状态为表状态。

像SELECT * FROM items WHERE name = "A" AND id AS status.itemid = 1这样的东西，但这不起作用。

Db结构：

表项目：

id      name
1       A
2       A
3       B

TABLE状态：

itemid      status
1           1
2           1
3           2

Answer 1

使用内部联接

select a.name, b.status 
from  items as a 
inner join status as b  on a.id = b.itemid
where a.name ='A' and b.status =1;
