数据库脚本给放一份，供测试使用

数据库脚本

这个有需求一点数学基础，应该初中或者高中都有讲过

1.并集 union（重复数据只显示一次）

--01.并集 union：  得到的结果集是多条slq执行的结果集的集合，重复数据只显示一次select tno from teacher where tno<1020
union
select tno from teacher where tno>1025

1.并集 union all(重复数据显示多次)

--01.并集 union all:  重复的数据只显示多次
select tno from teacher where tno<1020
union all
select tno from teacher where tno>1010

2.交集 insersect

--02.交集intersect:  取俩个结果集中的公共部分
select tno from teacher where tno<1020
intersect
select tno from teacher where tno>1010

3.补集 minus

--03.补集minus:要求第一条sql语句的查询结果数>第二条sql语句的查询结果数，并且第二个结果集都在第一个结果集中存在
select tno from teacher where tno<1025
minus
select tno from teacher where tno<1020
