It looks like you've entered a string that resembles an SQL injection attack. SQL injection is a code injection technique that exploits a vulnerability in an application's software. It's often used to interfere with the queries that an application makes to its database.
If you're testing a system or learning about SQL injections, it’s crucial to always have permission to do so and to operate within legal and ethical boundaries. Using such techniques on systems that you do not own or do not have explicit permission to test can be illegal and unethical.
If you have questions about SQL injection, database security, or how to protect against such attacks, feel free to ask!
