Combo/PopList/or LOV on the web

Question

I am deploying a forms 5.0 application on the web.
I need to present the user with a list of possible selections
that is generated from a SQL statement. (eg. create a poplist
that is populated with values from a dictionary table)
Question 1:
Is it possible to dynamically populate a
a. poplist
b. combo box
c. LOV
If so how?
Question 2:
Is there an advantage to using any one or the other from the web?
Thanks in advance,

Answer 1

Hi Dennis
Qusetion1
b) & c) It is possible to dynamically populate the combo box and
LOV. You should create the record group on the fly to do this.
You should use
FUNCTION POPULATE_GROUP_WITH_QUERY
(recordgroup_name VARCHAR2,
query VARCHAR2);
See the following example
DECLARE
group_id RecordGroup;
query_ok NUMBER;
BEGIN
/* create the group prod_group and assign its id to the
** variable group_id */
group_id := Create_Group_From_Query ('prod_group',
'SELECT product.id, product.name,
inventory.warehouse_id, inventory.amount_in_stock
FROM product, inventory
WHERE product.id = warehouse.product_id');
/* now execute the new group's query, using the variable
** group_id to identify the group */
query_ok := Populate_Group(group_id);
/* if the query failed, abort this trigger by raising a
** predefined exception */
IF query_ok <> 0 THEN
RAISE Form_Trigger_Failure;
END IF;
END;
That is all I could help you with.
