最近在学习Oracle,对测试人员而言必须掌握两种语言:第一种是DML,数据操纵语言 (Data Manipulation Language) 是SQL语言中,负责对数据库对象运行数据访问工作的指令集,以INSERT、UPDATE、DELETE三种指令为核心,分别代表插入、更新与删除。第二种是:DQL,数据查询语言 (Data Query Language) 是SQL语言中,负责进行数据查询而不会对数据本身进行修改的语句,这是最基本的SQL语句。核心指令为SELECT,以及一些辅助指令,如FROM、WHERE等,FROM:表示来源,可以搭配JOIN做链接查询; WHERE:过滤条件;GROUP BY:在使用聚合函数时用到,如SUM,COUNT,MAX,AVG;HAVING:对聚合结果进行筛选,这是和WHERE的不同点;ORDER BY:排序。
