我是sql的新手,
之间的区别是什么select vehicle.plates, make, model
from vehicle
join registration on registration.plates = vehicle.plates
where country = 'Japan';
和
select vehicle.plates, make, model
from registration, vehicle
where registration.plates = vehicle.plates and country=’Japan’;
答案 0 :(得分:0)
第一个查询符合ANSI标准,另一个查询不符合。
但是查询应该返回相同的结果。
