Problem set parameters of PS (queries stored on a property file)

Question

I am wrinting a small jsp application and storing the queries that it will use in a property file. Some fields on the main form are optional. How I can "build" the query correctly (leaving out the conditions that weren't filled in the form)?
I know it is trivial when you have the query on the page or class, but I can't think of a solution to keep storing the "dynamic" queries on a property file.
Any ideais?

Answer 1

I wanted to store all queries on the same file.
I don't need to retrive the query, I already have it but based on the user decisions it will change. Consider a form with 3 fields: name, id and number, all of them are optional. If the user fills all fields the query will be:
"SELECT id, nm, number
FROM a_table
WHERE id = 10
AND nm = 'foo'
AND num = '843'
ORDER BY nm
If the user fills only the "name" field the query will be:
"SELECT id, nm, number
FROM a_table
AND nm = 'foo
ORDER BY nm
As I said in my first post, it is trivial to this when storing the query on a jsp page or class file, but is it possible to with a property file?
thank you.
