The DAL doesn't have anything built in that will work across database backends, but if you are using MySQL, you should be able to do: db(query).select(orderby='Field(id, %s)' % ', '.join(str(id) for id in list_of_ids)) Alternatively, if the list is not too long, you can just do the sorting in Python after selection: db(query).select().sort(lambda r: list_of_ids.index(r.id)) Anthony -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
