Create Database and Tables with NHibernate and FluentNHibernate?


I'm looking for any way to create database and tables with NHibernate and FluentNHibernate.

How could I do this ?

trying.

private static ISessionFactory createConnection()
{
    if (session != null)
        return session;

    //database configs
    FluentConfiguration _config = Fluently.Configure().Database(
        MySQLConfiguration.Standard.ConnectionString(
            x => x.Server(HOST).
            Username(USER).
            Password(PASSWORD).
            Database(DB)
        ))
        .Mappings(m => m.FluentMappings.AddFromAssemblyOf<PerfilMap>())
        .Mappings(m => m.FluentMappings.AddFromAssemblyOf<ModuloMap>())
        .Mappings(m => m.FluentMappings.AddFromAssemblyOf<PermissaoMap>())
        .Mappings(m => m.FluentMappings.AddFromAssemblyOf<UsuarioMap>())
        .Mappings(m => m.FluentMappings.AddFromAssemblyOf<CategoriaMap>())
        .Mappings(m => m.FluentMappings.AddFromAssemblyOf<SubcategoriaMap>    ())
        .ExposeConfiguration(cfg => new SchemaUpdate(cfg).Execute(false, true));

    session = _config.BuildSessionFactory();
    return session;
}

Solution

  • Neither NHibernate nor FNH create the database itself. You have to provide either code or a precreated database yourself. But it can create the tables for you. The class doing this is call SchemaExport. In Fluent, it looks like this:

    var sessionFactory = Fluently.Configure()
       .Database(/* ... */)
       .Mappings(/* ... */)
       .ExposeConfiguration(cfg => new SchemaExport(cfg).Execute(true, true, false))
       .BuildSessionFactory();
