PL/SQL and Oracle Forms Builder

Question

So I need to put this project together for school, but I'm ONLY allowed to use oracle forms builder.

I'm trying to do a simple query and assign values to the form objects based on what I get from the query, but my form items are coming up as undeclared. Does anyone know how I can modify form attributes like this? This user interface on this program is awful, so doing it through the wizards is something I'd really like to avoid if I can just make things happen in PL/SQL.

Here's what I have: Still trying to find a working solution.

I've modified my code a bit:

DECLARE
    pmrn patient.p_mrn%TYPE;
    var_ptuple patient%ROWTYPE;
BEGIN
    pmrn := NAME_IN('MRN_FIELD');
    SELECT * INTO var_ptuple from patient WHERE patient.p_mrn = pmrn;
    :PATIENT_BLOCK.FNAME := var_ptuple.p_fname;
    :PATIENT_BLOCK.LNAME := var_ptuple.p_lname;
END;

Using the where on the data block doesn't really suit these purposes because I would like to retrieve the data based on the user input. Ie. the user needs to input the correct user ID to see their records.

Answer 1

Form items can be referred to as bind variables in Forms PL/SQL, e.g.

pmrn := :PATIENT_BLOCK.MRN_FIELD;
:PATIENT_BLOCK.FNAME := var_ptuple.p_fname;

etc.

Be aware, however, that you most probably don't need to write all this code. Just set the block source to be the table and execute a query on it - Forms will take care of loading the records for you.
