快速生成mysql上百万条测试数据

方案：编写一个存储过程循环添加数据

1. 创建表index_test

DROP TABLE IF EXISTS index_test;

CREATE TABLE index_test(

id BIGINT(20) PRIMARY KEY NOT NULL AUTO_INCREMENT,

USER VARCHAR(16) DEFAULT NULL,

psd varchar(64) default null

/*psd mediumint DEFAULT 0 存储随机数据*/

)ENGINE=MyISAM DEFAULT CHARSET=utf8;

2.创建存储过程

DELIMITER $$
DROP PROCEDURE IF EXISTS `insert_data`$$
CREATE PROCEDURE `insert_data`(IN tableName varchar(500),IN num INT)
BEGIN
  DECLARE n INT DEFAULT 1;/*定义一个变量，存储当前执行的次数*/
    WHILE n <= num DO
        SET @sqlStr = CONCAT("INSERT INTO ",tableName,"(USER,psd) VALUES(CONCAT(",n,",'用户'),password(",n,"))");
        PREPARE stmt FROM @sqlStr;
        EXECUTE stmt;
        set n=n+1;
  end while;
END $$

3.执行存储过程插入数据：

call insert_data('index_test',1000000);
