批量插入数据，不使用replace操作_牛客题霸

题目已经先执行了如下语句: 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 ('3', 'WD', 'GUINESS', '2006-02-15 12:34:33'); 对于表actor插入如下数据,如果数据已经存在，请忽略(不支持使用replace操作) actor_id first_name last_name last_update '3' 'ED' 'CHASE' '2006-02-15 12:34:33'

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 ('3', 'WD', 'GUINESS', '2006-02-15 12:34:33');

输出

3|WD|GUINESS|2006-02-15 12:34:33
