How to obtain NHibernate generated SQL in code at runtime?

Question

I know you can view the NHibernate generated SQL by hooking it up to log4net or piping it out to the console (\"show_sql\" option), but is there any way to obtain the generated

Answer 1

With NHibernate 3.2, this seems to work to get the SQL from an HQL query:

private string GetSQL(string hql)
{
    using (var iSession = ...)
    {
        var session = (NHibernate.Engine.ISessionImplementor)iSession;
        var sf = (NHibernate.Engine.ISessionFactoryImplementor)iSession.SessionFactory;

        var sql = new NHibernate.Engine.Query.HQLStringQueryPlan(hql, true, session.EnabledFilters, sf);

        return string.Join(";", sql.SqlStrings);
    }
}
