Oracle中插入千万条测试数据

Posted 2021-01-11 Lyle_Dong

测试需求，id、姓名、邮箱、手机号不可重复

1.创建序列

create sequence id_sequence;    //创建序列id_sequence

2.创建表

create table USERINFO(
ids number(11) NOT NULL,
activity_name varchar(255) NOT NULL,
intractive_type varchar(255) DEFAULT NULL NOT NULL,
email varchar(255) NOT NULL,
mobile int NOT NULL,
userAgent varchar(255) NOT NULL,
email_title varchar(255) NOT NULL,
label varchar(255) NOT NULL,
category1 varchar(255) NOT NULL,
time date NOT NULL,
time1 date    NOT NULL,
primary key(ids)
);

 3.for循环插入数据

declare
i number;
begin
   for i in 100..130    //100..130代表循环30次，按需求修改
     loop     
insert into USERINFO values(id_sequence.nextval,\'这是名字\'||id_sequence.nextval,\'现金\',137||lpad(id_sequence.nextval,8,0)||\'@qq.com\',137||lpad(id_sequence.nextval,8,0),2,1,2,20,to_date(\'2018-09-29\',\'yyyy-mm-dd\'),to_date(\'2018-09-29\',\'yyyy-mm-dd\'));
   end loop;
   commit;
end;

插入效果如下
