Namespace:  System.Data.OracleClient
Assembly:  System.Data.OracleClient (in System.Data.OracleClient.dll)

When you create an instance of OracleDataAdapter, the following read/write properties are set to their default values, as shown in the table.

Properties

Default value

MissingMappingAction

MissingMappingAction.Passthrough

MissingSchemaAction

MissingSchemaAction.Add

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

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

[C#]

{
    OracleConnection myOracleConnection = new OracleConnection("Data Source=Oracle8i;Integrated Security=yes");

    custDA.SelectCommand = new OracleCommand("SELECT DeptNo, CompanyName FROM Dept", myOracleConnection);
    custDA.InsertCommand = new OracleCommand("INSERT INTO Dept (DeptNo, CompanyName) " +
                                            "VALUES (:pDeptNo, :pCompanyName)", myOracleConnection);
