SQLAdapter update and datetime

[steve-0]

Hey,

I have a case where I fill a datatable with two column wich contain datetime. Il filled them and everything seems alright in debug. Problem is that when I update with the SQLAdapter, it says that it cannot insert NULL into a datetime column, but the fact is that it is not NULL.

Here what it looks like:

SqlConnection conn = new SqlConnection(ConfigurationManager.AppSettings["BD"]);

conn.Open();



adapter.InsertCommand = new SqlCommand("Commun.SP__PeriodeEnregistrer", conn);
adapter.InsertCommand.CommandType = CommandType.StoredProcedure;
adapter.InsertCommand.Parameters.Add("@idperiode", SqlDbType.Int, 10, "IDPeriode");
adapter.InsertCommand.Parameters.Add("@nosemaine", SqlDbType.Int,10,"NoSemaine");
adapter.InsertCommand.Parameters.Add("@annee", SqlDbType.Int, 10, "Annee");
adapter.InsertCommand.Parameters.Add("@periode", SqlDbType.Int, 10, "Periode_no");
adapter.InsertCommand.Parameters.Add("@datedebut", SqlDbType.DateTime, 150, "Debut_date");
adapter.InsertCommand.Parameters.Add("@datefin", SqlDbType.DateTime, 150, "Fin_date");
adapter.Update(dtPeriode);

Thanks in advance
