When you are using a data adapter to update a DataSet, the first order of business is to assign the UpdateCommand, DeleteCommand, and InsertCommand properties with valid command objects (until you do so, these properties return null!). By valid command objects, I am referring to the fact that the set of command objects you plug into a data adapter will change based on the table you are attempting to update. In this example, the table in question is Inventory. Here is the modified InsertNewCar() method: private static void InsertNewCar(SqlDataAdapter dAdpater) { // Gather info about new car. ... // Format SQL Insert and plug into DataAdapter. string sql = string.Format("Insert Into Inventory" + "(CarID, Make, Color, PetName) Values" + "('{0}', '{1}', '{2}', '{3}')", newCarID, newCarMake, newCarColor, newCarPetName); dAdpater.InsertCommand = new SqlCommand(sql); dAdpater.InsertCommand.Connection = cnObj; // Update Inventory Table with new row. DataRow newCar = dsCarInventory.Tables["Inventory"].NewRow(); newCar["CarID"] = newCarID; newCar["Make"] = newCarMake; newCar["Color"] = newCarColor; newCar["PetName"] = newCarPetName; dsCarInventory.Tables["Inventory"].Rows.Add(newCar); dAdpater.Update(dsCarInventory.Tables["Inventory"]); } Once you have created your command object, you plug it into the adapter via the InsertCommand property. Next, you add a new row to the Inventory DataTable maintained by the dsCarInventory object. Once you have added this DataRow back into the DataTable, the adapter will execute the SQL found within the InsertCommand property, given that the RowState of this new row is DataRowState.Added.

Public Function SaveEmployee(Employee As cPerson) As Boolean Dim blnReturn As Boolean If m_oWorksheet Is Nothing Then GoTo Exit_Function End If m_lngNewRowNum = m_oXL.FindEmptyRow(m_oWorksheet) Set m_oEmployee = Employee SaveEmpData SaveAddressData SaveEquipmentData SaveAccessData Exit_Function: SaveEmployee = blnReturn Exit Function End Function Add the following class initialization and cleanup code: Private Sub Class_Initialize() Set m_oXL = New cExcelUtils End Sub Private Sub Class_Terminate() Set m_oXL = Nothing End Sub The Worksheet property lets us define where the data will be stored in our workbook. The SaveEmployee method does a few things for us when we pass in a cPerson object: Public Function SaveEmployee(Employee As cPerson) As Boolean It checks to see that the Worksheet property has been set so we know where to save our data: If m_oWorksheet Is Nothing Then GoTo Exit_Function End If It finds the first empty row using the cExcelUtils object: m_lngNewRowNum = m_oXL.FindEmptyRow(m_oWorksheet) Then we assign the cPerson object we passed in to the method to a private module-level cPerson object that will be used in various save functions: Set m_oEmployee = Employee

There are a handful of other pseudo-classes, all of which are covered in detail in Appendix A of this book.

The modification of the UpdateCarPetName() method is more or less identical. Simply build a new command object and plug it into the UpdateCommand property. private static void UpdateCarPetName(SqlDataAdapter dAdpater) { // Gather info about car to update. ... // Format SQL Insert and plug into DataAdapter. string sql = string.Format ("Update Inventory Set PetName = '{0}' Where CarID = '{1}'", newPetName, carToUpdate); SqlCommand cmd = new SqlCommand(sql, cnObj); dAdpater.UpdateCommand = cmd; DataRow[] carRowToUpdate = dsCarInventory.Tables["Inventory"].Select( string.Format("CarID = '{0}'", carToUpdate)); carRowToUpdate[0]["PetName"] = newPetName; dAdpater.Update(dsCarInventory.Tables["Inventory"]); } In this case, when you select a specific row (via the Select() method), the RowState value of said row is automatically set to DataRowState.Modified. The only other point of interest here is that the Select() method returns an array of DataRow objects; therefore, you must specify the exact row you wish to modify.

Last but not least, you have the following update to the DeleteCar() method: private static void DeleteCar(SqlDataAdapter dAdpater) { // Get ID of car to delete. ,,, string sql = string.Format("Delete from Inventory where CarID = '{0}'", carToDelete); SqlCommand cmd = new SqlCommand(sql, cnObj); dAdpater.DeleteCommand = cmd; DataRow[] carRowToDelete = dsCarInventory.Tables["Inventory"].Select(string.Format("CarID = '{0}'", carToDelete)); carRowToDelete[0].Delete(); dAdpater.Update(dsCarInventory.Tables["Inventory"]); } In this case, you find the row you wish to delete (again using the Select() method) and then set the RowState property to DataRowState.Deleted by calling Delete().

You might agree that working with data adapters can entail a fair amount of code, given the need to build each of the four command objects and the associated connection string (or DbConnection-derived object) To help simplify matters, each of the ADONET data providers that ships with NET 20 provides a command builder type Using this type, you are able to automatically obtain command objects that contain the correct Insert, Delete, and Update command types based on the initial Select statement The SqlCommandBuilder automatically generates the values contained within the SqlDataAdapter s InsertCommand, UpdateCommand, and DeleteCommand properties based on the initial SelectCommand Clearly, the benefit is that you have no need to build all the SqlCommand and SqlParameter types by hand An obvious question at this point is how a command builder is able to build these SQL command objects on the fly The short answer is metadata.
