Attn: Oracle Form programmers - pls. help

Question

Can somebody pls. give me the syntax for writing Oracle Query Forms. I've done it before but forgotten the syntax.
The idea is to create a statement by APPENDING the search items in a program unit & substituting in the WHERE clause. This program unit will be called by a button.
This way, we don't have to write many IF statments.
For example, if user wants to query by NAME AND COUNTRY, then the statement >> Block:Name ||&|| Block:Country
Where clause: Block:Name ||&|| Block:Country
Thanks - Mave

1. that subject line of yours is just stupid. You're posting on an Oracle Forms Forum. Every single post on this forum is looking for help from Oracle Forms programmers.
Be specific.
2. I assume you're looking for something like
DECLARE
  v_default_where VARCHAR2(32767);
  v_btn NUMBER;
begin
  IF :control.name is not null then
    v_default_where := v_default_where||' AND name LIKE :control.name';
  END IF;
  IF :control.empno is not null then
    v_default_where := v_default_where||' AND empno = :control.empno';
  END IF;
  IF v_default_where IS NULL THEN
    v_btn := show_alert('NO_CRITERIA');
  ELSE
    v_default_where := SUBSTR(v_default_where,5); -- remove leading ' AND '
    set_block_property(data_block, ONETIME_WHERE, v_default_where);
    EXECUTE_QUERY;
  END IF;
END;
