for output columns, we have recently added a method for this purpose as of version 0.6.3: http://www.sqlalchemy.org/docs/reference/orm/query.html#sqlalchemy.orm.query.Query.column_descriptions I'm using it successfully in a library that converts Query objects into Excel spreadsheets with xlwt. > Similarly, how can I check, for instance, that the query object is > grouping on Employee.lastName? stuff like that is semi-private but relatively stable, most are available by names like query._group_by, query._order_by, query._criterion. If you look at the top of the Query class (the source), they are all defaulted at the class level. Semi-private because I really don't want to push things like that to be first class accessors until we are super certain nothing is changing there. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
