"order by code not in ('USD', 'EUR', 'CAD') , code" is exactly what I was looking for!

Good to know how "order by not in" works and thank you very much for all your inputs!

...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!
