The command that you entered is part of an if statement that is reading the database to see if your friend status is confirmed. However, that appears to be only a portion of the code. I would need to see the entire statement to determine whether or not you can change "Confirmed." Based upon where I think you pulled that code snippet from, the answer would probably be no. The reason is because the code itself is reading the friends table in your database and is literally looking for the status to say "Confirmed." Changing it from "Confirmed" would fail the statement, if you understand what I mean. The only way to keep the statement valid would be to change the SQL statement that made the table's friend status say "Confirmed" to begin with. However, the SQL statement that you would need to modify is encrypted.
