Class SchemaGenerator

java.lang.Object
  net.sf.basedb.core.hibernate.SchemaGenerator

All Implemented Interfaces:

org.hibernate.jdbc.Work

public class SchemaGenerator
extends Object
implements org.hibernate.jdbc.Work

Replaces the Hibernate SchemaExport and SchemaUpdate tools. We need this to be able to intercept and modify some of the SQL statments that Hibernate generates since they don't always work as expected. In particular, since Hibernate 3.5 they generate "not null" constraints for columns that are added to existing tables and we don't want that.

Since:

2.16
