there are some "not" operators but currently they arent attached to ColumnOperators. You can get them from sqlalchemy.sql.operators and they are: notin_op(), notlike_op(), notilike_op() so like: notin_op(left, right) as far as sticking them on ColumnOperators I'm a little concerned about more than one way to do it, but I suppose the analogue is in python: "not x is y" vs. "x is not y". So sure. but id rather keep on 0.8 for this as a lot of other aspects of operators are changing. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
