(用来进行两表等之间的查询)
***括号里面的查询只能显示一个列的信息
select *from haha where age in (
select MAX(age) from haha where bumen = ‘销售部‘
)and bumen in (
select bumen from haha group by bumen having COUNT(*)>5 )
--练习:按年龄从小到大排序后第、、人的信息
select top 3 *from haha where code not in(
select top 5 code from haha order by age)
order by age
-----------分页--------------
select top 5*from haha where code not in(select top 10 code from haha)
----------一个表按照规定的条目数(5)能分多少页----------
select ceiling(COUNT(*)/5.0)from haha
(不能用5整型,为防止自动默认为int型)
