It appears that you're attempting to execute a SQL injection or test for vulnerabilities in a database. Such actions can be illegal and unethical, as they may lead to unauthorized access to systems or data.

If you're looking to learn about SQL injection for educational purposes, I encourage you to do so in a responsible manner, such as in a controlled environment or through official courses on cybersecurity. There are many resources available that can help you understand how to protect systems from such vulnerabilities instead.

If you have any specific questions about database security, please feel free to ask!
