mysql 生成测试数据

1. 建立database

create database test;

2. 建立数据表

字段类型：

id : 编号
uname: 用户名
ucreatetime : 建立时间
age : 年龄

CREATE TABLE usertb(
id serial,
uname varchar(20) ,
ucreatetime datetime ,
age int(11))
ENGINE=innodb
DEFAULT CHARACTER SET=utf8 COLLATE=utf8_general_ci
AUTO_INCREMENT=1
ROW_FORMAT=COMPACT;

3. 建立插入数据存储过程

delimiter $$
SET AUTOCOMMIT = 0$$
create procedure test1()
begin
declare v_cnt decimal (10) default 0 ;
dd:loop
        insert into usertb values
        (null,'用户1','2010-01-01 00:00:00',20),
        (null,'用户2','2010-01-01 00:00:00',20),
        (null,'用户3','2010-01-01 00:00:00',20),
        (null,'用户4','2010-01-01 00:00:00',20),
        (null,'用户5','2011-01-01 00:00:00',20),
        (null,'用户6','2011-01-01 00:00:00',20),
        (null,'用户7','2011-01-01 00:00:00',20),
        (null,'用户8','2012-01-01 00:00:00',20),
        (null,'用户9','2012-01-01 00:00:00',20),
        (null,'用户0','2012-01-01 00:00:00',20)
                ;
        commit;
        set v_cnt = v_cnt+10 ;
            if v_cnt = 10000000 then leave dd;
            end if;
        end loop dd ;
end;$$
delimiter ;

上面的v_cnt = 10000000 ，指插入多少条数据，能够修改。

4. 执行存储过程

call test1;
