Assignee: Tore Halset (was: Andrus Adamchik)
> Add MergerToken to update database or model with PK Generation Strategy
> -----------------------------------------------------------------------
>
> Key: CAY-975
> URL: https://issues.apache.org/cayenne/browse/CAY-975
> Project: Cayenne
> Issue Type: Improvement
> Components: Cayenne Core Library
> Affects Versions: 3.0
> Reporter: Øyvind Harboe
> Assignee: Tore Halset
>
> I'm using DbMerger to update the DataMap with attributes from the database.
> This solves a raft of problems, including how to let database managers modify
> length of fields from e.g. SQL Manager(which they are comfortable with).
> My DataMap states that the pk is generated by the database, but when that is
> not the case I'll get this exception:
> Caused by: java.sql.SQLException: Cannot insert the value NULL into column
> 'user_id', table 'qpb.dbo.users'; column does not allow nulls. INSERT fails.
