Updating multiple records based on process date

Question

Hello,
I need to change the value of multiple records in one table if a condition is met for each record in another table when the application is run.
I have an Employee table containing employee names that also has a status field where the values are either "Active" or "Disabled".
There is a form in the application with an employee name select list using a dynamic LOV based on the Employee table. The LOV is restricted to "Active" employees. The form inserts employee-related transactions with the current date into the Transaction table.
I want to automatically update the status of all employees in the Employee table from "Active" to "Disabled" where there have been no transactions in the Transaction table for that employee for more than 2 months. This will allow me to exclude them from the dynamic LOV based on the Employee table.
Any suggestions are greatly appreciated.
Thank you,
Matt

Hi Matt
Something like this?
UPDATE employees
SET status = 'Disabled'
WHERE status = 'Active'
AND NOT EXISTS(SELECT 'X'
                                  FROM transactions
                                  WHERE emp_id = trn_emp_id
                                 AND tran_date >= SYSDATE - INTERVAL '60' DAY);Let me know if I've misunderstood...
Cheers
Ben
