Crazy I know, but what is the best way to PREVENT a report portlet from running ?

Question

I know this sounds a very weird question.
On a page I have a html form (that I use as search criteria for my report) as well as an actual report published as a portlet.
On certain situations, such as when going to the page initially, I require that the report not be executed due to bind variables passed by the form not being initialised.
I know I can set default values for parameters, and use decode statements in my query etc etc, but this means the report is still actually run, but no rows are returned!
I dont want the report to even run!
Is there a faster way of stopping a report from executing.
... before displaying the page - pl/sql
Would the best way to achieve this be the throwing of an unhandled exception?
declare
myException exception;
begin
if certain criteria is not met then
raise myException;
end;
regards,
Matt.

I have about 50GB of photos on my old MBP iphoto library.
To be able to merge your libraries, your Aperture version and iPhoto version must match. For basic reading see: Aperture 3.3: Using a unified photo library with iPhoto and Aperture
and Aperture 3.3: How to use Aperture to merge iPhoto libraries
Assuming you are running the latest Aperture and iPhoto versions:
Before merging libraries ensure that your iPhoto Library has no issues. While still on your old mac run the "library first aid tools" on your iPhoto Library. Hold down the key combination ⌥⌘ and double click your iPhoto Library, then select "Repair database".
Make sure you have a backup of your current Aperture Library and iPhoto library.
Do both macs have a FireWire port? Then you could connect your macs in Target Disk Mode:
See OS X Lion: Transfer files between two computers using target disk mode
This way your new mac could see your old mac as an external disk and you could copy directly between the macs.
Otherwise copy your iPhoto library by drag-and-drop to an external disk (on your old mac) and connect that disk to your new mac. Check, if the external drive is formatted for mac (MacOS X Extended (Journaled)). Otherwise reformat it, before you copy the iPhoto library to that drive.
When your iPhoto Library has been moved to your new Mac launch Aperture and use the command "File > Import > Library" from the main menu bar. If there are duplicates in the Aperture library (if you imported earlier from iPhoto) you may be prompted if you want to "Add" or "Merge". If you have lots of duplicates, pick "Merge", otherwise "Add".
Post back, if you need more detailed instructions.
Good Luck.
