Hi,

I try to use NHibernate.Tasks.Hbm2DdlTask and I get an error. Perhaps an error code from me !

I have an assembly which contain xml files for tables.
I create à new project and I code:

Code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using NHibernate;
using NHibernate.Tasks;

namespace Gensql
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            NHibernate.Tasks.Hbm2DdlTask hb = new NHibernate.Tasks.Hbm2DdlTask();
            hb.Execute();
        }
    }
}

My app.config is like that:

Code:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

  <hbm2ddl 
    
    connectionprovider="NHibernate.Connection.DriverConnectionProvider"
    dialect="NHibernate.JetDriver.JetDialect, NHibernate.JetDriver" 
    connectiondriverclass="NHibernate.JetDriver.JetDriver, NHibernate.JetDriver"
    connectionstring="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\Cardio.mdb" 
    delimiter=" GO " 
    outputtoconsole="false" 
    exportonly="true" 
    formatnice="true" 
    outputfilename="c:\\toto.sql">
    
    <assemblies>
       <include name="D:\\Développements\\CSharp\\Gensql\\RessourcesDBMS\\bin\\Release\\RessourcesDBMS.dll" />    
    </assemblies>
    
  </hbm2ddl>
  
  
</configuration>

When I run my project, I get several errors:

{"Une exception a été levée par l'initialiseur de type pour 'NAnt.Core.Types.FileSet'."}

{"Une exception a été levée par l'initialiseur de type pour 'log4net.Core.LoggerManager'."}

"Une exception a été levée par l'initialiseur de type pour 'log4net.Core.LoggerManager'."

etc.

I don't understandwhy all these errors.

Can you help me please ?

(sorry for bad english, frenchy here )

Hbm2DdlTask is an NAnt extension task and is meant to be used in an NAnt build file. It is not meant to be used directly. It seems to me you are trying to create the database schema in code. Have a look at the NHibernate.Tool.hbm2ddl.SchemaExport class instead.

Where is this class? Can it be used from comand line?

The class is in the main NHibernate.dll. Fully qualified name per above post. No, it cannot be used on the command line; unless, of course, you write a console app that invokes the class.
