What exactly will the @pN in NHibernate logs translate to in the SQL query

I would like to know exactly what SQL expression it is that gets run when NHibernate says it's going to run the following:

INSERT
INTO
    dbo_MainTable
    (AddedDate)
VALUES
    (@p0);
@p0 = 2015-03-13 15:38:18 [Type: DateTime (0)]

What will the @p0 translate to? Can you do something to print the exact SQL instead of this NHibernate SQL translation?
