Using names instead of codes in our forms.

Question

I have two tables:
1. Table A which has next 3 fields:
Code: CHAR 2
Name: VARCHAR2 40
Code_B: CHAR 1
2. Table B which has next 2 fields:
Code: CHAR 1 Primary key
Name: VARCHAR2 40
Between the table A and the table B there is a relationship which is made through Code_b field. In this sense the field Code_b in table A must belong to table B.
Now I would like to make a form using Oracle forms 6i which allow me to actualize insert, delete, change)rows in table A. The problem is that I would like to introduce the name instead of Code_B when I run the form and this name must be chosen from a combo list (not an LOV). At the same time when the table A is updated whicth the changes I have made in the Code_b field must obviously load the code not the name.
In other words I would like that users work with names but behind that the programs work with codes.
Please give me your advice as clear as possible. I am new in Oracle world, I am sure this thing is possible (in Fox this is a very simple thing) but I have been trying to do that for several days without any success.
Thank you for your advice.

Answer 1

Create a record group using the columns from TABLE_B:
SELECT name, code
FROM table_b
Use this record group to populate the list item in the PRE-FORM or WHEN-NEW-FORM-INSTANCE triggers.
return = populate_group(<record_group_name>);
clear_list(<list_name>);
populate_list(<list_item>, <record_group_name>);
You may want to look at the forms documentation for these built-in procedures.
