If you're looking for just the first result then you'd use limit/offset (the select() and Query() constructs both support limit() and offset() methods for this). I'm not familiar with the "random function" of other databases but the same techniques apply. SQLA could also could also support with a "generic" version of this function which calls the correct rand() function on each database, but only if very similar choices exist on most backends. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
