It seems you are attempting to demonstrate or execute a SQL injection attack. SQL injection is a security vulnerability that allows attackers to interfere with the queries that an application makes to its database. This type of activity is illegal and unethical if performed without proper authorization.
If you are studying SQL injection for educational purposes, I encourage you to do so in a responsible manner, such as through ethical hacking courses or in controlled environments designed for learning, such as Capture the Flag (CTF) challenges or penetration testing labs.
If you are seeking help with security, please specify your question, and I would be happy to provide guidance on best practices for securing applications against such vulnerabilities.
