Adding rows to Dataset and adding to Database

[Jawahar]

I have the following code

iAdapter = new SqlDataAdapter();
iUpdater = new SqlCommandBuilder(iAdapter);
dsROCData = new DataSet("ROC");
SetConnection("XXXXX"); --> set the connection
oCommROC = new SqlCommand();
oCommROC.Connection = oConn;
oCommROC.CommandType = CommandType.StoredProcedure;
oCommROC.CommandText = "GetROCFromIFMS";

iAdapter.SelectCommand = oCommROC;
int I = iAdapter.Fill(dsROCData, "ROCTemplatetable");
DataRow[] dr = ds.Tables["ROC"].Select();
foreach (DataRow d in dr)
{
dsROCData.Tables["ROCTemplatetable"].ImportRow(d);
}

if (dsROCData.HasChanges()
{
int j = iAdapter.Update(dsROCData,"ROCTemplatetable");
}
iAdapter.Dispose();

The problem is that I can never add the row to the databse it seems that the
DataSet has not changed even though I check the row count and I find that I
have added 100's of rows
Any Idea why?
