Im using NHibernate 1.2GA and tryng to use SchemaExport like this:
new SchemaExport(new Configuration()
.Configure(@"C:\SysAguas\hibernate.cfg.xml"))
.Execute(true, true, false, true);
fabricaSessao = new Configuration().Configure().BuildSessionFactory();


so i need that if exist the tables SchemaExport dont drop my tables in DB just try create and give errors that already exist tables like JPA do.
