Andrus Adamchik commented on CAY-1986:
--------------------------------------
the question is how to handle this in a reasonable way.
> SQLTemplate returning DataObjects fails on PK column case mismatch
> ------------------------------------------------------------------
>
> Key: CAY-1986
> URL: https://issues.apache.org/jira/browse/CAY-1986
> Project: Cayenne
> Issue Type: Bug
> Components: Core Library
> Affects Versions: 4.0.M2
> Environment: trunk
> Reporter: John Huss
> Priority: Minor
>
> If you create an SQLTemplate query that returns real DataObjects (say Artist
> objects) and use a query like "select * from Artist limit 1" and have the
> primary key column defined in the DataMap with mixed case (like artist_ID)
> that doesn't match what the database returns for the column name, the result
> will contain nulls instead of objects.
> Strangely the case of the other columns does not seem to matter, only the
> primary key column.
> You can workaround it by naming the column all upper or lower case and
> configuring the SQLTemplate to force upper or lower case column names to be
> returned. But I think it should just work without needing to do this.
