mySQL你如何做一個連接鏈？

Question

嗨！我想弄清楚如何在同一行代碼中的多個步驟中進行連接。這是我得到了這麼遠，但我得到一個錯誤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

試試這個：

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';
