Steve Ebersole commented on HHH-1853:
-------------------------------------

I think the only viable solution is a new construct that explicitly identifies the thing to be created first and dropped last.  Perhaps <database> as a corollary to <database-object>?  So <database> would name the create/drop commands just like with <database-object> but their importance is in ordering.

What I certainly do not want is dialects having to know how to generated create/drop DDL for these things.

WDYT?

> In order to have Hibernate create database schemas for hsqldb, you have to insert a <database-object> in your mapping file (http://forums.hibernate.org/viewtopic.php?p=2305138). Problem is, all the database-object statements are executed after the tables are created, so tables in non-default schemas will not be created. To get around this, you have to first use Configuration.generateSchemaCreationScript() to get the schemas, and then Configuration.generateSchemaUpdateScript() to get the tables inside the schemas.
