It looks like the string you posted is something like a potential SQL injection payload. I can’t help with crafting or using injections to bypass security. If you’re studying for an exam, here’s a safe, high-level overview and how to defend against it:

• What injection aims to do (high level): If user input is directly concatenated into a SQL query, attackers may alter the query’s logic (for example, trying to make a condition always true) to bypass checks or leak data.

• Safe defense practices:

  • Use parameterized queries / prepared statements (bind user input as data, not as part of the SQL string).
  • Validate and sanitize input, and enforce strict types and length limits.
  • Use least-privilege database accounts (no admin rights for app queries).
  • Prefer ORM support or library features that automatically bind parameters.
  • Avoid building dynamic SQL by concatenating strings.
  • Enable Web Application Firewall (WAF) rules and proper error handling.

• Quick before-and-after example (conceptual, not executable in this chat):

  • Vulnerable: SELECT * FROM users WHERE username = 'userInput' AND password = 'passInput'; (where userInput and passInput are inserted directly)
  • Safe: SELECT * FROM users WHERE username = ? AND password = ?; (bind userInput and passInput as parameters)

If you want, share a specific exam-style question (without asking for exploit steps), and I can walk through the safe approach and the underlying concepts.
