Trevor Kaufman commented on CAY-1271:
-------------------------------------

Hello,

 I'd like to register my interest in this being fixed. The company I work for is evaluating the usage of Cayenne for our Java Development but currently the migrate database schema is unusable. The database is huge, but several projects just need to merge with a smaller schema which is part of the database.

> Currently merging does not allow schema selection (loadDataMapFromDb() is fired with null 'schema' argument). In such cases, when I try to migrate on Oracle, the method returns all Oracle service tables (more than 7000!) and getting columns enum from those service tables fails with ora-01424 exception.
> Cayenne should somehow allow schema selection for migration process and use datamap's "default schema" property as default
