So the first table that needs to be saved is the Animals table, followed by the Pets table using the key received from the Animals table, and finally the PetBelonging table thus, a topdown approach. The insert command for the Animals table, insertAnimalCommand, is shown in Listings 10-3 and 10-4. Listing 10-3. Setting Up the insertAnimalCommand in C# SqlCommand insertAnimalCommand = new SqlCommand(); insertAnimalCommand.Connection = testConnection; insertAnimalCommand = new SqlCommand("UP_ANIMALINSERT"); insertAnimalCommand.CommandType = CommandType.StoredProcedure; param = new SqlParameter("@AnimalID", SqlDbType.Int, 4, "AnimalID"); param.Direction = ParameterDirection.Output; insertAnimalCommand.Parameters.Add(param); param = new SqlParameter("@AnimalType", SqlDbType.VarChar, 50, "AnimalType"); param.Direction = ParameterDirection.Input; insertAnimalCommand.Parameters.Add(param); insertAnimalCommand.Transaction = trans; Listing 10-4. Setting Up the insertAnimalCommand in Visual Basic .NET Dim insertAnimalCommand As SqlCommand = New SqlCommand() insertAnimalCommand.Connection = testConnection insertAnimalCommand = New SqlCommand("UP_ANIMALINSERT") insertAnimalCommand.CommandType = CommandType.StoredProcedure param = New SqlParameter("@AnimalID", SqlDbType.Int, 4, "AnimalID") param.Direction = ParameterDirection.Output insertAnimalCommand.Parameters.Add(param) param = New SqlParameter("@AnimalType", SqlDbType.VarChar, 50, "AnimalType") param.Direction = ParameterDirection.Input insertAnimalCommand.Parameters.Add(param) insertAnimalCommand.Transaction = trans Curiously enough, look at the last statement in these two listings. What is effectively being done is a transaction is being set up. Even though transactions will be covered in depth in the next chapter, at this point it s sufficient to understand that the commands executed upon the three tables must lie within a transaction because if for some reason an insert on the PetBelongings table fails, you don t want to leave orphan rows in either the Pets table or the Animals table. A transaction will ensure that all the rows will either insert and be committed, or will not insert and will be rolled back together. Setting up a transaction is fairly easy and can be achieved with the following code:

Interestingly, if you browse through the code for AnimalsTableAdapter a little bit, you ll find that this command is a SqlCommand representation of the command text you specified in Figure 9-5. The code for setting up such commands can be found in the InitCommandCollection method. This can be seen in Listings 9-5 and 9-6. Listing 9-5. AnimalsTableAdapter.InitCommandCollection Method in C# private void InitCommandCollection() { this.m_commandCollection = new System.Data.SqlClient.SqlCommand[1]; this.m_commandCollection[0] = new System.Data.SqlClient.SqlCommand(); this.m_commandCollection[0].Connection = this.Connection; this.m_commandCollection[0].CommandText = "SELECT AnimalID, AnimalName FROM dbo.Animals"; this.m_commandCollection[0].CommandType = System.Data.CommandType.Text; } Listing 9-6. AnimalsTableAdapter.InitCommandCollection Method in Visual Basic .NET Private Sub InitCommandCollection() Me.m_commandCollection = New System.Data.SqlClient.SqlCommand(0) {} Me.m_commandCollection(0) = New System.Data.SqlClient.SqlCommand Me.m_commandCollection(0).Connection = Me.Connection Me.m_commandCollection(0).CommandText = _ "SELECT AnimalID, AnimalName FROM dbo.Animals" Me.m_commandCollection(0).CommandType = System.Data.CommandType.Text End Sub CommandCollection is an array because one TableAdapter can hold multiple commands. Next, look up the code for the definition of the Delete(int Original_AnimalID, string Original_AnimalName) overload. This is shown in Listings 9-7 and 9-8. Listing 9-7. AnimalsTableAdapter.Delete(int Original_AnimalID, string Original_AnimalName) Method in C# public virtual int Delete(int Original_AnimalID, string Original_AnimalName) { this.Adapter.DeleteCommand.Parameters[0].Value = ((int)(Original_AnimalID)); if ((Original_AnimalName == null)) { throw new System.ArgumentNullException("Original_AnimalName"); } else { this.Adapter.DeleteCommand.Parameters[1].Value = ((string)(Original_AnimalName)); } System.Data.ConnectionState previousConnectionState = this.Adapter.DeleteCommand.Connection.State; this.Adapter.DeleteCommand.Connection.Open(); try { return this.Adapter.DeleteCommand.ExecuteNonQuery();

finally { if ((previousConnectionState == System.Data.ConnectionState.Closed)) { this.Adapter.DeleteCommand.Connection.Close(); } } } Listing 9-8. AnimalsTableAdapter.Delete(int Original_AnimalID, string Original_AnimalName) Method in Visual Basic .NET Public Overloads Overridable Function Delete( _ ByVal Original_AnimalID As Integer, _ ByVal Original_AnimalName As String) As Integer Me.Adapter.DeleteCommand.Parameters(0).Value = _ CType(Original_AnimalID,Integer) If (Original_AnimalName Is Nothing) Then Throw New System.ArgumentNullException("Original_AnimalName") Else Me.Adapter.DeleteCommand.Parameters(1).Value = _ CType(Original_AnimalName,String) End If Dim previousConnectionState As System.Data.ConnectionState = _ Me.Adapter.DeleteCommand.Connection.State Me.Adapter.DeleteCommand.Connection.Open Try Return Me.Adapter.DeleteCommand.ExecuteNonQuery Finally If (previousConnectionState = System.Data.ConnectionState.Closed) Then Me.Adapter.DeleteCommand.Connection.Close End If End Try End Function Again, this code takes an AnimalID and AnimalName as parameters to the function, sets a parameter on a command (DeleteCommand), and simply uses the ExecuteNonQuery method to execute the command. If you look up the definition of DeleteCommand, you can find that it is the InitAdapter private method. Its definition looks like as shown in Listings 9-9 and 9-10. Listing 9-9. DeleteCommand in C# this.m adapter.DeleteCommand = new System.Data.SqlClient.SqlCommand(); this.m adapter.DeleteCommand.Connection = this.Connection; this.m adapter.DeleteCommand.CommandText = "DELETE FROM [dbo].[Animals] WHERE (([AnimalID] = @Original_AnimalID) AND ([Animal" + "Name] = @Original_AnimalName))"; this.m adapter.DeleteCommand.CommandType = System.Data.CommandType.Text; this.m adapter.DeleteCommand.Parameters.Add(

new System.Data.SqlClient.SqlParameter("@Original_AnimalID", System.Data.SqlDbType.Int, 0, System.Data.ParameterDirection.Input, 0, 0, "AnimalID", System.Data.DataRowVersion.Original, false, null, "", "", "")); this.m adapter.DeleteCommand.Parameters.Add( new System.Data.SqlClient.SqlParameter("@Original_AnimalName", System.Data.SqlDbType.VarChar, 0, System.Data.ParameterDirection.Input, 0, 0, "AnimalName", System.Data.DataRowVersion.Original, false, null, "", "", "")); Listing 9-10. DeleteCommand in Visual Basic .NET Me.m_adapter.DeleteCommand = New System.Data.SqlClient.SqlCommand Me.m_adapter.DeleteCommand.Connection = Me.Connection Me.m_adapter.DeleteCommand.CommandText = _ "DELETE FROM [dbo].[Animals] WHERE (([AnimalID] = @Original_AnimalID) " & _ " AND ([Animal" & _ "Name] = @Original_AnimalName))" Me.m_adapter.DeleteCommand.CommandType = System.Data.CommandType.Text Me.m_adapter.DeleteCommand.Parameters.Add( _ New System.Data.SqlClient.SqlParameter("@Original_AnimalID", _ System.Data.SqlDbType.Int, 0, System.Data.ParameterDirection.Input, 0, 0, _ "AnimalID", System.Data.DataRowVersion.Original, false, Nothing, "", "", "")) Me.m_adapter.DeleteCommand.Parameters.Add( _ New System.Data.SqlClient.SqlParameter("@Original_AnimalName", _ System.Data.SqlDbType.VarChar, 0, _ System.Data.ParameterDirection.Input, 0, 0, _ "AnimalName", System.Data.DataRowVersion.Original, _ false, Nothing, "", "", "")) As a matter of fact, if you look through the code of InitAdapter, the various table mappings, adapters, and commands are set up within this private method. The full code for InitAdapter is shown in Listings 9-11 and 9-12. Listing 9-11. InitAdapter in C# private void InitAdapter() { this.m_adapter = new System.Data.SqlClient.SqlDataAdapter(); System.Data.Common.DataTableMapping tableMapping = new System.Data.Common.DataTableMapping(); tableMapping.SourceTable = "Table"; tableMapping.DataSetTable = "Animals"; tableMapping.ColumnMappings.Add("AnimalID", "AnimalID"); tableMapping.ColumnMappings.Add("AnimalName", "AnimalName"); this.m_adapter.TableMappings.Add(tableMapping); this.m_adapter.DeleteCommand = new System.Data.SqlClient.SqlCommand();
