针对actor表创建视图actor_name_view_牛客题霸

针对actor表创建视图actor_name_view，只包含first_name以及last_name两列，并对这两列重新命名，first_name为first_name_v，last_name修改为last_name_v： CREATE TABLE actor ( actor_id smallint(5) NOT NULL PRIMARY KEY, first_name varchar(45) NOT NULL, last_name varchar(45) NOT NULL, last_update datetime NOT NULL); 后台会插入2条数据: insert into actor values ('1', 'PENELOPE', 'GUINESS', '2006-02-15 12:34:33'), ('2', 'NICK', 'WAHLBERG', '2006-02-15 12:34:33'); 然后打印视图名字和插入的数据

示例1

输入

drop table if exists actor;
CREATE TABLE  actor  (
   actor_id  smallint(5)  NOT NULL PRIMARY KEY,
   first_name  varchar(45) NOT NULL,
   last_name  varchar(45) NOT NULL,
   last_update datetime NOT NULL);
insert into actor values ('1', 'PENELOPE', 'GUINESS', '2006-02-15 12:34:33'), ('2', 'NICK', 'WAHLBERG', '2006-02-15 12:34:33');

输出

['first_name_v', 'last_name_v']
PENELOPE|GUINESS
NICK|WAHLBERG
