select * from
(
select stu.*, ter.name
from student as stu, ter as term
where stu.t_id = ter.id
) as t
where t.id > 10
错误:
select * from
(
select stu.*, ter.*
from student as stu, ter as term
where stu.t_id = ter.id
) as t
where t.id > 10
因为student和term表中都存在id 合的表要用来查询,不充许有重复列
下面是可以的:
select stu.*, ter.*
from student as stu, ter as term
where stu.t_id = ter.id
他不作为条件,再用来查询了
