How do you auto-populate a field?

Question

Hello.
If I present the user with a LOV's on an 'Insert Form', how do I auto-poulate a value in the same form based on what the user has just selected?
e.g.
User selects 'Employee Number' from a LOV, I then want to auto-populate the 'Employee Name' underneath.
I thought a simple sql query would get me the EMP_FULL_NAME FROM EMPLOYEES where EMPNO = (whatever EMPNO user has just selected).
TIA.

Hi Tia,
You are right you should just be able to use a query as the source of your page item for name. I will base my description below on page 1 and using APEX 4.
First of all you will need to set your :P1_USER_ID select list to submit the page so the value is set in session state, if you navigate to the settings section and then set Page Action when Value Changed to submit page.
You will then need to have a query as the source of :P1_NAME and a query something like
  SELECT
    name
  FROM
    users
  WHERE
    user_id = :P1_USER_ID;One thing to not you will need to make sure you on submit processes are conditional based on a button else they will run when the user_id select lists is changed.
An alternative method to submitting the page would be to use a dynamic action providing your using APEX 4. The dynamic action could be fired when the value of :P1_USER_ID is changed and then update the value :P1_NAME dynamically.
Hope this helps
