dataAdapter Update method columns matching problem

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
