OK the answer for now is to disable this test, and I will add a requirements rule so that people stop hitting this, as the identical situation occurred in october: https://groups.google.com/forum/#!searchin/sqlalchemy/group$20by$20dialect|sort:date/sqlalchemy/r4X7ddN4rgA/c4HMI2qhBAAJ you can also see background in that thread for how to actually get the "GROUP BY ix" syntax if you wanted to do so (though not in that test). > > Also I needed to add: > ``` > @property # WTF > def broken_cx_oracle6_numerics(self): > return exclusions.closed() > ``` > and others to the requirements of my dialect to get the testsuite running at > all. Shouldn't sqlalchemy ship with sane default requirements (I mainly > followed > https://github.com/zzzeek/sqlalchemy/blob/master/README.dialects.rst )? that's also a bug, that rule should have been removed before the 1.2 release as it should no longer be necessary. > > Thanks and best regards, > Florian > > -- > SQLAlchemy - > The Python SQL Toolkit and Object Relational Mapper > > http://www.sqlalchemy.org/ > > To post example code, please provide an MCVE: Minimal, Complete, and > Verifiable Example.
