[sqlalchemy] bad result when querying for null values (in pk at least)
hello friends, thank you very much for making and contributing to this great project. i have a table with a multi-field primary key, one of which allows null. when querying this table, i don't get the records with null in that field, even if i'm specifically asking them in where. but what makes the result wrong is, that one None is entering the result records list. and None is not a record. what do you think? -- alex smime.p7s Description: S/MIME Cryptographic Signature

thanks a lot mike, it's working great now. but this flag should be implied if one of the primary key fields is nullable (especially since it's not nullable by default). what would you think?

You can argue just as easily that the null primary key means the record is incomplete and should not be available. It's an application code issue. but i'm talking about nullable=True --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups sqlalchemy group.

According to http://www.sqlalchemy.org/trac/wiki/06Migration the flag will be turned on by default in 0.6 it's indeed redundant, thanks.
