nHibernate to single column lookup table

Question

I would like to have a simple lookup table in the database with a single numeric non-integer column. While the column is currently a primary key, nHibernate complains if I specify the type as non-integer (I need it to be a decimal). I can add a surrogate key column to this table, or is there a simple solution that I can implement with nHibernate to manage (read/insert/delete) the values in this table without needing a surrogate key column?

I guess I could use this code to select, but what about insert/delete? What's the best approach?

Answer 1

NHibernate only complains if the specified keygenerator doesn't support the type. I guess you haven' specified any generator which defaults to identity which can only handle integral types. with assigned you could provide the ids

Id(x => x.Id).GeneratedBy.Assigned();
