How To Retrieve Objects based on Other Unique Columns

[mirzaei-mm]

Hello,

I have a table which has a candidate key named "Id", and as you know, all tables have "objectId" too.
how can I retrieve an object based on the "Id" column?
I want to use get() method like this: MyTable.Query.get(Id='xxxxxxx'), instead of MyTable.Query.get(objectId='yyyyyy')

Thanks
