I'm wondering whether there's a way to obtain the details of the database fields that are mapped to the properties of an NHibernate entity.

For example, I want to find out the length of a varchar field in the database that maps to a 'name' field at runtime so that the UI of the application can dynamically determine the length of a text field to display, thereby preventing the user from entering a value that will cause a runtime exception when trying to persist the value.

I know that there are methods on the SessionFactory which allow you to obtain metadata on the registered classes, but so far I haven't been able to find the information I'm looking for.

Has anyone out here worked out how to do this?

Just re-raising this one since it's been about a week and the forums have been a bit unreliable.

Is there any way to access details of the database schema (varchar length, float precision, etc) from the NHibernate metadata?

Symon.

I've read in Hibernate.org about sessionfactory.getClassMetadata - is here in NHibernate something simmilar, too?

There is a metadata method on the session factory, but it doesn't actually contain information about the database read from the database, only information inferred through the mapping files and reflection, or so it appears.

:(
