MySQL如何利用存储过程快速生成100万条数据详解

首先，创建要插入100万数据的表格

创建函数

随机产生字符串

DELIMITER $$
CREATE FUNCTION rand_string(n INT) RETURNS VARCHAR(255)
BEGIN
 DECLARE chars_str VARCHAR(100) DEFAULT 'abcdefghijklmnopqrstuvwxyzABCDEFJHIJKLMNOPQRSTUVWXYZ';
 DECLARE return_str VARCHAR(255) DEFAULT '';
 DECLARE i INT DEFAULT 0;
 WHILE i < n DO
 SET return_str =CONCAT(return_str,SUBSTRING(chars_str,FLOOR(1+RAND()*52),1));
 SET i = i + 1;
 END WHILE;
 RETURN return_str;
END $$

随机产生数字

DELIMITER $$
CREATE FUNCTION rand_num( ) 
RETURNS INT(5)
BEGIN 
 DECLARE i INT DEFAULT 0;
 SET i = FLOOR(100+RAND()*10);
RETURN i;
 END $$
 
 
#假如要删除
#drop function rand_num;

创建存储过程

并向表中插入数据

#执行存储过程，往sdb_b2c_order表添加随机数据
DELIMITER $$
CREATE PROCEDURE insert_sdb_b2c_orders(IN START INT(10),IN max_num INT(10))
BEGIN
DECLARE i INT DEFAULT 0; 
 SET autocommit = 0;
 REPEAT
 SET i = i + 1;
 INSERT INTO sdb_b2c_orders (order_id ,seller_order_id,total_amount,final_amount,source,source_name,merchant_bn ) VALUES
 (rand_string(10) ,rand_string(10),100,100,'eleme','square',(START+i));
 UNTIL i = max_num
 END REPEAT;
 COMMIT;
 END $$;
 
 
#删除
# DELIMITER ;
# drop PROCEDURE insert_emp;

调用存储过程进行插入数据

 #插入30万条数据分几次插入
 CALL insert_sdb_b2c_orders(700003,300000); 

结果
