Generar un nuevo registro en una BD
 

Buenas:
Quiero insertar un nuevo registro en una base de datos de la siguiente forma:

OracleConnection oc = new OracleConnection();
oc.ConnectionString = @ConfigurationSettings.AppSettings["connectionString"];
oc.Open();
NwHistAdapter = new OracleDataAdapter("select * from SUBJECT_HISTORY us where us.SUBJECT_ID =" + strParent ,oc);
histCmdBuilder = new OracleCommandBuilder(NwHistAdapter);
histDataSet = new DataSet("histDataSet");
NwHistAdapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
NwHistAdapter.Fill(histDataSet, "SUBJECT_HISTORY");
DataRow dtrNewHist = histDataSet.Tables["SUBJECT_HISTORY"].NewRow();

dtrNewHist["SUBJECT_ID"]=strParent.ToString();
dtrNewHist["HISTORY_DATE"]=DateTime.Now;
dtrNewHist["DESCRIPTION"]=txtDescription.Text;
dtrNewHist["SUB_USER_ID"]=1;
dtrNewHist["LAST_CONTACT_DAY"]=txtLast.Text;
dtrNewHist["NEXT_ACTION_DATE"]=txtNext.Text;
dtrNewHist["ACTION_ID"]=txtNext_action.Text;
dtrNewHist["EFFECT_ID"]="24";
dtrNewHist["DURATION"]=12;
dtrNewHist["SUB_CONTACT_ID"]=strId;
dtrNewHist["SERVICE_ID"]=txtService.Text;

histDataSet.Tables["SUBJECT_HISTORY"].Rows.Add(dtrNewHist);
histDataSet.AcceptChanges();
NwHistAdapter.Update(histDataSet,"SUBJECT_HISTORY" );

Pero me aparece el siguiente error:

Server Error in '/EasySales' Application.

Según lo que he leido tiene que ver con las llaves que estan contenidas en las otras tablas.

¿Me equivoco? , alguien puede ayudarme porfavor , aunque tenga que hacerlo on un INSERT INTO en vez del OracleCommandBuilder?
