both? the rowproxy is addressable by lots of things like strings, Column objects. if we want to add negative index support i can accept PRs. probably only for a major version like 1.1, 1.2 etc. > > If the latter, should the fix go into the BaseRowProxy (C and pure Python > version) class or into the ResultMetaData._key_fallback() method? negative integer indexes can be worked out in terms of the positive ones so not sure key_fallback is necessary. > > Thank you, > ciao, lele. > -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
