mysql 快速生成百万条测试数据

20) NOT NULL AUTO_INCREMENT COMMENT ‘ID‘, `card_number` varchar(100) DEFAULT NULL COMMENT ‘卡号‘, PRIMARY KEY (`card_id`) ) ENGINE=MyISAM AUTO_INCREMENT=0 DEFAULT CHARSET=utf8 CHECKSUM=1 DELAY_KEY_WRITE=1 ROW_FORMAT=DYNAMIC

 

2.创建MYSQL存储过程

DROP PROCEDURE IF EXISTS proc1;
DELIMITER $$
SET AUTOCOMMIT = 0$$
CREATE  PROCEDURE proc1()
BEGIN
DECLARE v_cnt DECIMAL (10)  DEFAULT 0 ;
dd:LOOP
          INSERT  INTO card (card_number) VALUES (UUID());
                  COMMIT;
                    SET v_cnt = v_cnt+1 ;
                           IF  v_cnt = 10000000 THEN LEAVE dd;
                          END IF;
         END LOOP dd ;
END;$$
DELIMITER ;

　3.调用存储过程，生成对应的测试数据

call proc1;

4.来测试一下性能吧。

select * from card order by rand() limit 1;   //6.5秒查询完毕
select * from card where card_number like ‘%xxx%‘; //3.7秒查询完毕
