Hi,
You will need to add an post delete trigger that adds the record row back in.
This is from forms 6i help:
** Built-in: ADD_GROUP_ROW
** Example: Add ten rows to a new record group and populate.
PROCEDURE Populate_My_Group IS
rg_name VARCHAR2(20) := 'My_Group';
rg_col1 VARCHAR2(20) := rg_name||'.NumCol';
rg_col2 VARCHAR2(20) := rg_name||'.CharCol';
rg_id RecordGroup;
gc_id GroupColumn;
in_words VARCHAR2(15);
BEGIN
** Check to see if Record Group already exists
rg_id := Find_Group( rg_name );
** If it does, then clear all the rows from the group and
** populate ten rows with the numbers from 1..10 along
** with the equivalent number in words.
** Row# NumCol CharCol
** 1 1 one
** 2 2 two
** 10 10 ten
IF NOT Id_Null(rg_id) THEN
Delete_Group_Row( rg_id, ALL_ROWS );
FOR i IN 1..10 LOOP
** Add the i-th Row to the end (bottom) of the
** record group, and set the values of the two cells
in_words := TO_CHAR(TO_DATE(i,'YYYY'),'year');
Add_Group_Row( rg_id, END_OF_GROUP );
Set_Group_Number_Cell( rg_col1, i, i);
Set_Group_Char_Cell( rg_col2, i, in_words);
END LOOP;
END IF;
END;
If you are unhappy about using record groups in this way, you might want to think about using a session temporary table. Do a direct insert into this table every time one gets selected and delete the record every time gets removed from your block. Your lov then simply becomes:
select mytab.*
from my_table mytab
where not exists (select 'already chosen'
from my_session_temp_table mytemp
where mytemp.primary_key = mytab.primary key)
The session temporary table need only hold the primary key vales.
You could probably so the same with a PL/SQL table but I find them hard work. Primarily because I never use them often enough to become comfortable, not because there is anything majorly wrong with them.
One last thought, you could use the base table of the block that you are selecting in the 'not exists' clause. You'd need to post the selects and deletes but it should work. Unfortunately it will post all changes not just the ones you want so it could have a knock on affect.
