Fluent Nhibernate how to ignore mapping columns from an existing table

Question

Is it possible to map a class in model to a table that has more columns than the model class? I just want to map specific columns of a table using Fluent Nhibernate. For example the table has these columns:

ProductId
ProductName
BatchNumber
StoreId

but in the model class I just want: ProductId, ProductName. Is it possible not to include BatchNumber and StoreId in the model class?

You can override mapping:

public class ProductAutoMappingOverride : IAutoMappingOverride<Product> {

    public void Override(AutoMapping<Product> mapping) {
       mapping.Id(p => p.ProductId),
       mapping.Map(p => p.ProductName),
       mapping.IgnoreProperty(p => p.BatchNumber);
       mapping.IgnoreProperty(p => p.StoreId);
    }

}
