This is the terminator . It attempts to break out of the developer's intended string literal. If the application does not sanitize input, the database engine will see this quote and assume the original command has ended, allowing the attacker to append their own logic.

The ORDER BY clause tells the database to sort results by a specific column. -5025 ORDER BY 1#

Successful use of this payload is the first step in a larger attack. Once the number of columns is known, an attacker can use a UNION SELECT statement to: Extract usernames and passwords. Bypass authentication screens. Gain administrative access to the server. This is the terminator

The string is a classic example of a SQL Injection (SQLi) payload, specifically used for database reconnaissance. The ORDER BY clause tells the database to

This is often a "false" or "null" value. By inputting a value that likely doesn't exist (like a negative ID), the attacker forces the application to return an empty result set or an error. This makes it easier to see how the database reacts when the injected code is added. ORDER BY 1 : This is the structural probe .

SQL Injection is a vulnerability where an attacker interferes with the queries an application makes to its database. The payload "-5025 ORDER BY 1#" is an "Inference" or "Error-based" probe used to determine the structure of a database table without having direct access to the source code.
