I am a beginner with PD.
I would like to know if it is possible to modelize the UNIQUE constraint in the models ?
Thanks for your help.

So, i found the solution for my problem.
to create alternative key you need to follow what described in this link infocenter.sybase.com/help/index.jsp?topic=/…
If you got in the preview Tab :
-- The preview is empty because of the setting. -- Check the generation option.
If you've just generated a script for a table, your preview pane will not show any content . So, you need to go into: • The 'Database' menu. • There go to the 'Generate database...' item. • Click on the 'Keys & Indexes' tab and make sure that in the left tree pane the 'Create alternate ' and 'outside' are check-marked. • Then save those settings by clicking 'Apply'. • Then click 'Cancel' to close the Database Generation dialog. • Next, if you do a preview on a table the content should be available again.
thanks all.
