Select lists and deactivated values

Question

Consider the following simplified test case.
1. create tables like this
create table lov_values
  lov_pk number primary key
, name varchar2(10)
, active varchar2(1) not null
insert into lov_values valeus ( 1, 'A', 'Y' );
insert into lov_values valeus ( 2, 'B', 'Y' );
insert into lov_values valeus ( 3, 'C', 'Y' );
commit;
create table trx
  trx_pk number not null primary key
, lov_fk number not null foreign key references lov_values
) ;2. Create an APEX Insert/Update form on the trx table. Define the LOV_FK item as a select list with this query
List of values definition:
  select name d, lov_pk r
  from   lov_values
  where  active = 'Y' ;
Display Extra Values: Yes3. Users use the APEX form to create records like this:
  trx( trx_pk, lov_fk ) = ( 10, 1 )   -- users sees LOV_FK value as "A"
  trx( trx_pk, lov_fk ) = ( 20, 2 )   -- users sees LOV_FK value as "B"
  trx( trx_pk, lov_fk ) = ( 30, 3 )   -- users sees LOV_FK value as "C"4. A year later an admin deactivates lov_value 2/B by setting active to 'N'.
5. When a user queries trx row 10 they still see "A".
6. When a user queries trx row 20 they now see "2".
7. When a user queries trx row 30 they still see "C".
In step 6 I'd like the user to see "B" whenever they query old data with that value but I never want them to be able to create new trx rows with 2/B or update the LOV_FK value of existing rows to be 2/B. I'd also like to avoid using a pick list with a popup window just for selecting from a list of two (could be a few) values.
Just wondering how others have dealt with this scenario in their APEX apps.

Answer 1

I actually just found a simpler way in Select list filter in a tabular form problem forum thread. In the query that defines the tabular form I added a column called HIDDEN_FK_VALUE as follows.
select
"TRX_PK",
"TRX_PK" TRX_PK_DISPLAY,
"LOV_FK",
APEX_UTIL.SAVEKEY_NUM("LOV_FK") hidden_fk_value
from "#OWNER#"."TRX"Then I modified the the Select List query to look like this.
SELECT name d, lov_pk r
FROM lov_values
WHERE (active = 'Y' OR lov_pk = APEX_UTIL.KEYVAL_NUM )Works like a charm. Thanks everyone for your input.
