I've set up a query page that allows users to set various criteria to filter oceanographic data - 800,000 records by 40 columns. The search works great, very fast, but the results include all 40 data columns. If the user is only interested in 6 columns, is there straightforward way to make the 'columns of interest' user selectable using checkboxes or ?? If doable, would it be easier to select columns before the search or after before exporting? Cheers.
