sql生成随机测试数据

利用sql语句产生随机测试数据

详细代码如下

create database test;
use test;

drop table if exists `card` ;
CREATE TABLE `card` (
   `card_id` bigint(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;

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;
                  num = 10000;
                    SET v_cnt = v_cnt+1 ;
                           IF  v_cnt = num THEN LEAVE dd;
                          END IF;
	END LOOP dd ;
END;$$
DELIMITER ;

call proc1;

num用来设置产生的数据条数。
