Hello all,

Just trying out Postgresql for the first time, coming from MySQL. In our Rails application we have a couple of locations with SQL like so:

SELECT * FROM `currency_codes` ORDER BY FIELD(code, 'GBP', 'EUR', 'BBD', 'AUD', 'CAD', 'USD') DESC, name ASC

It didn't take long to discover that this is not supported/allowed in Postgresql.

Does anyone know how to simulate this behaviour in Postgres or do we have to pull to sorting out into the code?

Thanks

Peer
