i have radius billing system with mysql as DB. I want to know which user 'password' was changed in last 5 minutes So that I can fetch such user mobile number from the DB and send SMS Alert about the password change event.
Here is the table structure
DB name = radius
Table name = rm_users (where all users information is stored)
Sample:
mysql> select * from rm_users;

2 rows in set (0.00 sec)`

I think you should be doing something like this.
Compare the separate table password with rm_users password for each user
2.1 if the password is not same - changed - perform the following task.
You can even add date_time column for last password change, counter for how many times changed...extra , so the new table will act as extra meta information table.
You also need to check if any new user is added or any user is deleted.
