Hi Marc,

I was looking into RFE: #1145 (Preview SQL instead of executing it.). I was thinking to start implementing this feature by:

I) Placing a "Preview SQL" button on the following pages and dialogs:
    1) Create table and Change table structure page.
    2) Insert/Edit table row(s) page.
    3) Relation view page.
    4) Add/Edit Index dialog.
II) Displaying the SQL in a jQuery dialog using Ajax.

I have attached some sample images. Please comment and correct me if I am missing something.
 
Regards,
Ashutosh Dhundhara
