Static Nested Class 和Inner Class的不同
Static nested class(嵌套类)是将内部类声明为static.普通内部类对象隐式地保存了一个引用,指向创建它的外围类对象,不能有static数据和static字段。嵌套类意味着:1> 要创建嵌套类的对象,并不需要其外围类的对象;2>不能从嵌套类的对象中访问非静态的外围类的...

HASH JOIN ,MERGE JOIN ,NESTED LOOP用法效率比较
概述: NESTED LOOP: 对于被连接的数据子集较小的情况,嵌套循环连接是个较好的选择。在嵌套循环中,内表被外表驱动,外表返回的每一行都要在内表中检索找到与它匹配的行,因此整个查询返回的结果集不能太大(大于1 万不适合),要把返回子集较小表的作为外表(CBO 默认外表是驱动表),而且在内表的连...
