I know that much. That is how I can generate
the form to begin with in the first place (and
the query statement, something like
SELECT FOO, MAN, CHU FROM MYTABLE, in the second
My question is what would I do after that? An answer
might be to invoke an external method passing the
column names I collected from the form. I am sure
this is a solution which will work. I just feel
there must be some other means to achieve what I
want without invoking an external method.
Let me reinstate the problem concisely. I have a
dtml method which gives a form. When user checks
or unchecks checkboxes and press submit button,
an action (which is also a dtml method) is invoked.
That action collects data (column names of a table)
dynamically. How would I do actuall database
query using this very data?
I would appreciate it if you (or anybody esle!) would
tell me what framework/means I would employ/deploy.
