MissingMappingAction MissingMappingAction.Passthrough
MissingSchemaAction MissingSchemaAction.Add

You can change the value of any of these properties through a separate call to the property.

Example

[Visual Basic, C#, C++] The following example creates an OracleDataAdapter and sets some of its properties.

[Visual Basic] 
Public Sub CreateOracleDataAdapter()
    Dim myOracleConnection As OracleConnection = New OracleConnection("Data Source=Oracle8i;Integrated Security=yes")
    Dim custDA As OracleDataAdapter = New OracleDataAdapter
    custDA.MissingSchemaAction = MissingSchemaAction.AddWithKey    
   
    custDA.SelectCommand = New OracleCommand("SELECT DeptNo, DName FROM Dept", myOracleConnection)
    custDA.InsertCommand = New OracleCommand("INSERT INTO Dept (DeptNo, DName) " & _
                                            "VALUES (:pDeptNo, :pDName)", myOracleConnection)
    custDA.UpdateCommand = New OracleCommand("UPDATE Dept SET DeptNo = :pDeptNo, DName = :pDName " & _
                                            "WHERE DeptNo = :pDeptNo", myOracleConnection)
    custDA.DeleteCommand = New OracleCommand("DELETE FROM Dept WHERE DeptNo = :pDeptNo", myOracleConnection)

    custDA.InsertCommand.Parameters.Add("pDeptNo", OracleType.Number, 2, "DeptNo")
    custDA.InsertCommand.Parameters.Add("pDName", OracleType.VarChar, 14, "DName")
 
    custDA.UpdateCommand.Parameters.Add("pDeptNo", OracleType.Number, 2, "DeptNo")
    custDA.UpdateCommand.Parameters.Add("pDName", OracleType.VarChar, 14, "DName")
    custDA.UpdateCommand.Parameters.Add("poldDeptNo", OracleType.Number, 2, "DeptNo").SourceVersion = DataRowVersion.Original

    custDA.DeleteCommand.Parameters.Add("pDeptNo", OracleType.Number, 2, "DeptNo").SourceVersion = DataRowVersion.Original
End Sub
