Replaces (MySQL) instances of space character (' ') with comments '/**_**/'
|
|
|
|
Tested against:
|
|
* MySQL 8.4.9
|
|
* MariaDB 11.8.8
|
|
* PostgreSQL 16.11
|
|
* SQLite 3.45.1
|
|
* Microsoft SQL Server 2022
|
|
* Oracle 23ai
|
|
|
|
Notes:
|
|
* Useful to bypass weak and bespoke web application firewalls
|
|
* Despite the script's name, '/**_**/' is a valid comment on every engine
|
|
listed above, not just MySQL
