Query based on parameters

Question

Hello,
I have two forms. The first takes several values that are entered and then passes them as parameters to the second form. How can I retrieve all records (execute query) in the second form based on the passed parameters.
What I want to do is search a specific table for values that match those parameters (=), or are based on a condition(>,< ...).
Some of the fields in the first form might also be left empty if I dont want to include them in my search.
I would be grateful for any help !
Thanks

Try this in a pre-query trigger... I didnt test this for typos... But, this is the basic jist of how to do it...
declare
  v_where_clause varchar2(4000);
begin
v_where_clause := '1 = 1';
if :empno is not null then
  v_where_clause := v_where_clause || ' and empno = :empno';
end if;
if :job is not null then
  v_where_clause := v_where_clause || ' and job = :deptno';
end if;
set_block_property('myblock', default_where, v_where_clause);
end;Message was edited by:
