Mysql批量新增测试数据

1、去掉主键自动递增，去掉主键

2、批量生成数据

 

insert into sys_user (select * from sys_user);
insert into '表名' (select * from '表名');

 

3、生成数据后修改主键

 

set @idl = 0;
UPDATE sys_user set duleId = (@idl := @idl + 1)
###duleId 对应修改的主键字段

 

4、设置主键，设置自动递增

 

 

 

delimiter //
DROP PROCEDURE IF EXISTS proc_batch_insert;
CREATE PROCEDURE proc_batch_insert()
BEGIN
DECLARE pre_name BIGINT;
DECLARE ageVal INT;
DECLARE i INT;
SET pre_name=187635267;
SET ageVal=100;
SET i=1;
WHILE i <= 1000000 DO
        INSERT INTO t_user(`name`,age,create_time,update_time) VALUES(CONCAT(pre_name,'@qq.com'),(ageVal+1)%30,NOW(),NOW());
SET pre_name=pre_name+100;
SET i=i+1;
END WHILE;
END //
 
delimiter ;
call proc_batch_insert();
