An example based on Scott's EMP table (which contains the HIREDATE column (that would be your DOB column, right?)).
First of all, set the HIREDATE column to a non-database column (in its Property palette).
Then, create a PRE-QUERY trigger on the EMP block as
declare
l_hire varchar2(20);
l_where varchar2(200);
begin
if :emp.hiredate is not null then
-- convert entered date value into a character string, using the 'DD-MM' format mask
l_hire := to_char(:emp.hiredate, 'dd-mm');
-- create a WHERE clause for that block
l_where := 'to_char(e.hiredate, ''dd-mm'') = ' ||
'''' || l_hire || '''';
-- set data block's ONETIME_WHERE property
set_block_property('emp', onetime_where, l_where);
end if;
end;
Finally, you have to correctly populate HIREDATE non-database column with its value. In order to do that, use POST-QUERY trigger:select hiredate
into :emp.hiredate
from emp
where empno = :emp.empno;
For example, I entered 17-12 into the HIREDATE column. After query has been executed, the result is
