...order by currency not in('USD', 'AND', 'CAD');
this condition will be avaluated as FALSE for USD, AND and CAD, and as TRUE for all other currencies. When the records are sorted the "false" are placed on the top because false<true;.

Good morning,
I have a currency table (code, description).
Example values:
ADF | Andorran Franc
... ...
ANG | NL Antillian Guilder
AON | Angolan New Kwanza
AUD | Australian Dollar
AWG | Aruban Florin
BBD | Barbados Dollar
USD | US Dollar
CAD | Canadian Dollar
Is there a way I can query to display USD AND CAD first, while other rows are ordered by Code.
For example,
CAS | Canadian Dollar
USD | US Dollar
ADF | Andorran Franc
...
Thanks a lot!
