如果要判斷不在兩者之間用not between x and y 就KO了，看個簡

單的查詢語句

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

20
    -> ORDER BY Name;

重要事項：不同的數據庫教程對 BETWEEN...AND 操作符的處理方式是

有差異的。某些數據庫會列出介於 "Adams" 和 "Carter" 之間的

人，但不包括 "Adams" 和 "Carter" ；某些數據庫會列出介於

"Adams" 和 "Carter" 之間並包括 "Adams" 和 "Carter" 的人；

而另一些數據庫會列出介於 "Adams" 和 "Carter" 之間的人，包

括 "Adams" ，但不包括 "Carter"
