Runtime Query

[Kenia Nimesh]

I have around 5 comboboxes.The user has option of selecting the comboboxes in all combinations and permutations.I fire a database query with parameters that the user selects in the given comboboxes. So if the user selects values from all the comboboxes then in my select statement I will have five parameters in the where clause. If the user selects four the four parameters in the where clause. So in all it turns out to be 5* 4 * 3 * 2 * 1 combinations. How should I handle this situation.I am using Oracle as my Database Server.   thanks in Advance Nimesh Kenia
