: In MySQL, this is a comment symbol. It tells the database to ignore the rest of the legitimate code, preventing syntax errors that would break the attack. Why You Should Care
It looks like you're testing for vulnerabilities! That specific string— -1469 UNION ALL SELECT 34,34# —is a classic example of a payload used to bypass security or leak data from a database.
: The attacker is trying to match the number of columns in the original query. If the page loads "34," they know the table has two columns and they can start pulling real data (like usernames or passwords) in those slots. -1469 UNION ALL SELECT 34,34#

SQL injection is a web security vulnerability that allows an attacker to interfere with the queries that an application makes to its database. Breaking Down the Payload:
If you were looking to write a blog post about this topic, here is a quick breakdown of what it means and why it matters: What is SQL Injection (SQLi)? That specific string— -1469 UNION ALL SELECT 34,34#
The best way to prevent this is to use (parameterized queries). This ensures the database treats the input as literal text, not as a command to be executed.
