SchemaUpdate asks for all referenced mapping documents when updating a single table
-----------------------------------------------------------------------------------

                 Key: HHH-2638
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2638
             Project: Hibernate3
          Issue Type: Improvement
    Affects Versions: 3.2.0 cr1
         Environment: myql, 
            Reporter: bhomass


I believe the idea of doing schema update is so that you can update a single table with a single property. However, as I try this feature out, hibernate continues to throw exception because this table I want to update refers to an unmapped class. I can move to the next step by adding another map file, but then more and more unmapped classes get involved, and pretty soon, I am feeding the entire collection of map files. So that's no different from updating the entire database.

I think it should be possible automatically read out the existing schema of the referenced tables from the database, so that their mapping files don't need to be supplied to SchemaUpdate, and these referenced tables do not inadvertently get updated too (with no net effect of course).
