Mysql快速插入测试数据

真的很好用很方便，复制到sqlyog把F9（执行sql的快捷点）往死里按吧！

INSERT INTO `sys_project` (
  `proj_name`,
  `dept_val`,
  `created`,
  `updated`
) 
VALUES
  (SUBSTRING(MD5(RAND()),1,10),
  (SELECT dval FROM sys_dept ORDER BY RAND() LIMIT 1),
  NOW(),
  NOW());

上面的sql的表结构是这样的：

[sys_dept]        [sys_project]    
 
  dval----\         proj_id
           \        proj_name
            \-------dept_val        
                    created
                    updated

(SUBSTRING(MD5(RAND()),1,10)用来产生一个长度为10的随机字符串

(SELECT dval FROM sys_dept ORDER BY RAND() LIMIT 1)用来从sys_dept表随机抽取一个dval的值作为sys_project的外键
