chapter9 子查询
关键字in和exists如何选择？
e.g.
SELECT * FROM A WHERE cc IN (SELECT cc FROM B)
SELECT * FROM A WHERE EXIST (SELECT cc FROM B WHERE B.cc=A.cc)
实际上在查询过程中，在我们对 cc 列建立索引的情况下，还需要比较A表和B表的大小。
在这个例子中，表 A 指的是 player 表，表 B 指的是 player_socre表。如果表A比表B大，那么IN比EXISTS的查询效率高，因为B表对cc列创建了索引，那么IN子查询的效率高。
如果A表比B表小，那么使用EXISTS效率高，因为可以使用到A表中对cc列的索引，而不用从B表中进行cc列的查询。
IN表是外边和内表进行hash连接，是先执行子查询。
EXISTS是对外表进行循环，然后在内表进行查询。
因此如果外表数据量大，则用IN，如果外表数据量小，也用EXISTS。
IN有一个缺陷是不能判断NULL，因此如果字段存在NULL值，则会出现返回，因为最好使用NOT EXISTS。
#9-1 筛选最大生命值大于 6000 的英雄，按照主要定位进行分组，按照分组英雄数从高到低进行排序，并显示每个分组的英雄数量、主要定位和平均最大生命值。
