Creating LOV with Where clause

Question

I'm trying to create a list of values from a select statementsomething like this
select customer_name, customer_number from customer
where Region = 'WEST';
I'm able to create a list of values of all the customers and numbers, but I could not
create a lov for a specific subset of that data, such as in the where clause.
Is it possible to create a LOV with a where clause?

Answer 1

Use bind variables to accept the region parameter. Also, it is good practice to accept a null parameter value. If your parameter is null, display the entire list of values. Your query would look something like this:
select customer_name, customer_number from customer
where Region = :region_name or
:region_name is null;
