The following example creates an OracleDataAdapter and sets some of its properties.

[Visual Basic]

Public Sub CreateOracleDataAdapter()
    Dim myConnectionText As String = "Data Source=Oracle8i;Integrated Security=yes"
    Dim mySelectText As String = "SELECT DeptNo, DName FROM Dept"
    Dim custDA As OracleDataAdapter = New OracleDataAdapter(mySelectText, myConnectionText ) 
    Dim myOracleConnection As OracleConnection = custDA.SelectCommand.Connection

    custDA.MissingSchemaAction = MissingSchemaAction.AddWithKey   
   
    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#]

public static void CreateOracleDataAdapter() 
{
    string myConnectionText = "Data Source=Oracle8i;Integrated Security=yes";

    string mySelectText = "SELECT DeptNo, DName FROM Dept";

    OracleDataAdapter custDA = new OracleDataAdapter(mySelectText, myConnectionText );
   OracleConnection myOracleConnection = custDA.SelectCommand.Connection;

    custDA.MissingSchemaAction = MissingSchemaAction.AddWithKey;
   
    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;
