将要进行批量插入的sql语句:
INSERT INTO `cloud2_activity`.`c_shop_barcode_out_flow` (
`barcode`,
`shop_user_id`,
`materials_id`,
`materials_style`,
`materials_name`,
`point`,
`phone`,
`create_date`,
`province`,
`city`,
`rate`
)
VALUES
(
'0kIsLvz9YcnuQ285',
'2',
'13',
'1',
'test',
'40',
'',
'2017-01-20 17:29:28',
'局域网',
'其他地区',
'0.00'
);
python生成随机字符串:http://www.cnblogs.com/longsecond/p/6118943.html
创建mysql函数,输入为:n即字符串的长度, 输出为:长度为n的随机字符串:
CREATE FUNCTION rand_string(n INT) RETURNS VARCHAR(255)
BEGIN
DECLARE chars_str varchar(100) DEFAULT 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
DECLARE return_str varchar(255) DEFAULT '';
DECLARE i INT DEFAULT 0;
WHILE i < n DO
SET return_str = concat(return_str,substring(chars_str , FLOOR(1 + RAND()*62 ),1));
SET i = i +1;
END WHILE;
RETURN return_str;
END
创建mysql存储过程: (declare语句用法介绍: http://blog.csdn.net/superbfly/article/details/12612037)
delimiter //
create procedure kmind()
begin
declare i int; # declare语句是在复合语句中声明变量的指令
set i=1;
while i<=1000000 do
insert into `cloud2_activity`.`c_shop_barcode_out_flow`(`barcode`,
`shop_user_id`,
`materials_id`,
`materials_style`,
`materials_name`,
`point`,
`phone`,
`create_date`,
`province`,
`city`,
`rate`) values(rand_string(16), # 使用函数:rand_string(16)
'2',
'13',
'1',
'test',
'40',
'',
'2017-01-20 17:29:28',
'局域网',
'其他地区',
'0.00');
set i=i+1;
end while;
end
//
delimiter ;
CALL kmind() # call 调用存储过程
drop procedure kmind; # 删除mysql存储过程
drop function rand_string; # 删除mysql函数
