求大神指点，如何写这个SQL，要求通用，如果有高级一点的写法也可以附上，谢谢。 作者: fangty 时间: 2015-8-3 10:07
select* from sc where sno<>'s001'minus
(
select* from sc
minus
select * from sc where sno='s001'
)

Select sno,sname from student where student.sno in
(Select distinct sno from sc where sc.cno in
(Select cno from sc where sno = ‘s001’)) 作者: liudinglong 时间: 2015-8-5 00:35
