Question

I’m getting back into NHibernate and I’ve noticed a new configuration property being used in examples: SchemaAutoAction. I cant seem to find documentation on what the various settings mean. The settings / my guesses as to what they mean are:

• Recreate — Drop and recreate the schema every time

• Create — If the schema does not exist create it

• Update — issue alter statements to make the existing schema match
  the model

• Validate — Blow up if the schema differs from the model

Is this correct?

SchemaAutoAction is the same as schema-action mapping attribute.

As per docs:

The new ‘schema-action’ is set to none, this will prevent NHibernate
from including this mapping in its schema export, it would otherwise
attempt to create a table for this view
