mySQL你如何做一个连接链？

Question

嗨！ 我试图找出如何在同一行代码的多个步骤中进行联接。 这是我到目前为止所得到的，但出现错误1064。

select * from jbcity
join jbsupplier on jbsupplier.city = jbcity.name where jbcity.state = "Mass"
join jbsupply on jbsupply.supplier = jbsupplier.id
join jbparts  on jbparts.id = jbsupply.part;

Answer 1

尝试这个：

select * from jbcity
join jbsupplier on jbsupplier.city = jbcity.name 
join jbsupply on jbsupply.supplier = jbsupplier.id
join jbparts  on jbparts.id = jbsupply.part where jbcity.state = 'Mass';
