Sorting on non database fields

Question

Hi,
I have a Master-Detail form ( query only form). The detail block has 10 DB fields and 2 NON DB fields (check boxes) . I have implemented Sorting functionality in such a way that, I have buttons on the top of each field and if the button is pressed on , let us say for Eg. Emp Name, sorting should be done on Emp Name and followed by other fields.
Order by clause after pressing Emp Name looks as follows:
Order by empname, empno, sal,......
But can we implement the sorting functionality for check boxes also ? ( Check boxes are non DB Fields )
These check boxes are populated with cursor in POST-QUERY trigger at block level ( check boxes are in Detail block.)
how to implement soring on these two check boxes?
Cheers

Thanks Every one,
We can have 2 approaches:
1. Since my block is based on the view, i have to change my view, to include
the Non- DB check box values. I can get the check box values using a function.
2. Another approach is , write a SELECT statement to select all the
coumns from the view along with the two NON-DB fields, (using function )
and use this SELECT clause in the QUERY SOURCE property of the block.
Thanks a lot for your help.
