如果要判断不在两者之间用not between x and y 就KO了，看个简

单的查询语句

mysql> SELECT Name, InStock, OnOrder, Reserved
    -> FROM Topic
    -> WHERE (InStock+OnOrder-Reserved) NOT BETWEEN 10 AND

20
    -> ORDER BY Name;

重要事项：不同的数据库教程对 BETWEEN...AND 操作符的处理方式是

有差异的。某些数据库会列出介于 "Adams" 和 "Carter" 之间的

人，但不包括 "Adams" 和 "Carter" ；某些数据库会列出介于

"Adams" 和 "Carter" 之间并包括 "Adams" 和 "Carter" 的人；

而另一些数据库会列出介于 "Adams" 和 "Carter" 之间的人，包

括 "Adams" ，但不包括 "Carter"
