Insert DataTable rows to DataBaseTables using DataAdapter: leave out one column in DataTable

Question

i have DataTable named dtPurchaseProduct that has columns

• dtcolPurchaseProduct_No
• dtcolnInvoiceNo
• dtcolnProductNo
• dtcolnProductName
• dtcolnQuantity
• dtcolnPrice

these are bound to datagridview except dtcolnProductNo because only product names are required to be seen

and i have DatabaseTable Named PurchaseProduct that has columns

• PurchaseProduct_No
• InvoiceNo
• ProductNo
• Quantity
• Price

now after allowing user to add/update/delete the DataTable rows through textboxes i want to insert these rows to DataBaseTable with DataAdapter

Is it possible to do that? i don't have select command and even the columns are not exactly the same that is i don't have database column for dtlcolnProductName

Answer 1

string qry = "select * from PurchaseProduct where 0 = 1";
        sa = new SqlDataAdapter(qry, conn);
        dataSet = new DataSet();
        sa.Fill(dataSet);
        dataSet.Tables[0].Columns.Add("dtcolnPurchaseProductProductName",typeof(string));
