Fluent NHibernate AutoMapping SchemaExport - Change object model and Keeping Data

Is there a way for the fluent automapping to alter a schema when the data object model changes (adding a new property to a class), currently it only drops and recreates the database schema, which would lose all the data in the database. Can it use Alter table instead of drop / create table, or am I just dreaming?

Can fluent update the database schema according to automapping without losing data?

Cheers,

Solution

  • Doh!

    Just use 

    new SchemaUpdate(config).Execute(false, true);

    instead of 

    new SchemaCreate(config).Execute(yadda yadda);
