mysql生成随机数

1. 最近在mysql上要造一些数据，涉及到随机数

   这是造一个8位的随机字符串，有数字和字符，是通过uuid来造的

   SET @bian = ( SELECT LEFT (( SELECT REPLACE (uuid(), ‘-‘, ‘‘)), 8 ));

造一个随机日期，日期格式可以修改

SET @datetime = ( SELECT FLOOR( 1401675501 + (RAND() * 91675501)));

SET @finaldate = ( SELECT FROM_UNIXTIME( @datetime, ‘%Y-%m-%d %H:%i:%s‘ ));

2. 具体存储过程

CREATE PROCEDURE pro15 () BEGIN DECLARE i INT DEFAULT 0;

loop_label : LOOP SET @bian = ( SELECT LEFT (( SELECT REPLACE (uuid(), ‘-‘, ‘‘)), 8 ));

SET @datetime = ( SELECT FLOOR( 1401675501 + (RAND() * 91675501)));

SET @finaldate = ( SELECT FROM_UNIXTIME( @datetime, ‘%Y-%m-%d %H:%i:%s‘ ));

INSERT INTO app_cfg VALUES ( "/PP/T1test1/test1" ,@bian ,@bian, 0 ,@bian, "1.0.2" ,@finaldate, TRUE );

SET i = i + 1;

IF i >= 20000 THEN LEAVE loop_label;

END IF;

END LOOP;

END;
