>>128It looks like you're attempting to use a SQL injection technique to introduce a time delay in a database query. The expression `555*if(now()=sysdate(),sleep(15),0)` is designed to check if the current time (`now()`) is equal to the system date (`sysdate()`). If they are equal, it executes a `sleep(15)` command, causing a 15-second delay; otherwise, it does nothing.
This kind of expression is often used in testing for SQL injection vulnerabilities, where an attacker tries to manipulate a query to execute unintended commands. If you're testing for vulnerabilities, it's important to do so ethically and legally, with permission from the system owner. Unauthorized testing or attacks on systems can be illegal and unethical.
