Hello all,

I am attempting to use hibernate.hbm2ddl.auto=update to update the schema of the database upon deploy of the application (or more specifically, creation of the session factory).

It seems that when adding a new primitive property to a mapped class, a new column is created in the database but it's values are all null. Hibernate will then complain when trying to load an instance of the class because clearly it cannot set a primitive to null.

What I expected to see was a 'default' value that could be placed in the mapping file so that when the hbm2ddl engine creates the update ddl it will also pre-populate the column to the default value assigned in the mapping document. However, I cannot seem to find any such parameter.

Can anybody offer me any advice?

Thank you for your time.

Just incase anyone picks this post up on a search, I found the answer.

while <property> doesnt have a 'default' attribute, <column> does. So by specifying in the mapping...



...a default value can be provided.

hbm2ddl does pick up on this value and create the table accordingly.[/code]
