[Solved]How to create ADF interface View

Question

Hi All,
I have a design problem that I need some help with.
In one of the pages in our application, we have two drop down boxes one with account type and another with account name (label) and account number (value).
The account types are Escrow, Credit and Misc (some other types). all three types are in three different tables.
Now the problem is, in the page when the account type is selected, the second drop down box should be filled with respective account numbers.
So my question is Can I create an interface view and implement in all three different account type views and use it for second drop down box.
Thanks in advance for your help.
Thanks
Praveen

You might do a VO with a union of the three tables - use a custom SELECT like this:
SELECT 'Escrow' account_type, account_number, balance, ... FROM escrow_accounts
UNION
SELECT 'Credit', account_number, balance, ... FROM credit_accounts
UNION
SELECT 'Misc.', account_number, balance, ... FROM misc_accountsUse NULL for any column in a table that does not have that column. I'm not sure if you can use Entity Objects (one EO per table) with such a VO to make the data updatable - it might have to be a read-only VO.
Or create a database view with this SELECT and base the VO on that view instead of a table. You can even make the view updatable with INSTEAD OF triggers and base an EO on the view.
