특성

예제

다음 예제에서는 파생 클래스 OleDbDataAdapter 를 만들고 해당 속성 중 일부를 설정합니다.

public static OleDbDataAdapter CreateCustomerAdapter(
    OleDbConnection connection)
{
    OleDbDataAdapter dataAdapter = new OleDbDataAdapter();
    OleDbCommand command;
    OleDbParameter parameter;

    // Create the SelectCommand.
    command = new OleDbCommand("SELECT CustomerID FROM Customers " +
        "WHERE Country = ? AND City = ?", connection);

    command.Parameters.Add("Country", OleDbType.VarChar, 15);
    command.Parameters.Add("City", OleDbType.VarChar, 15);

    dataAdapter.SelectCommand = command;

    // Create the DeleteCommand.
    command = new OleDbCommand(
        "DELETE * FROM Customers WHERE CustomerID = ?",
        connection);

    parameter = command.Parameters.Add(
        "CustomerID", OleDbType.Char, 5, "CustomerID");
    parameter.SourceVersion = DataRowVersion.Original;

    dataAdapter.DeleteCommand = command;

    return dataAdapter;
}
Public Shared Function CreateCustomerAdapter( _
    connection As OleDbConnection) As OleDbDataAdapter 

    Dim dataAdapter As New OleDbDataAdapter()
    Dim command As OleDbCommand
    Dim parameter As OleDbParameter

    ' Create the SelectCommand.
    command = New OleDbCommand("SELECT CustomerID FROM Customers " & _
        "WHERE Country = ? AND City = ?", connection)

    command.Parameters.Add("Country", OleDbType.VarChar, 15)
    command.Parameters.Add("City", OleDbType.VarChar, 15)

    dataAdapter.SelectCommand = command

    ' Create the DeleteCommand.
    command = New OleDbCommand( _
        "DELETE * FROM Customers WHERE CustomerID = ?", _
        connection)

    parameter = command.Parameters.Add( _
        "CustomerID", OleDbType.Char, 5, "CustomerID")
    parameter.SourceVersion = DataRowVersion.Original

    dataAdapter.DeleteCommand = command

    Return dataAdapter
End Function

설명

중에 Update이 속성이 설정되지 않고 기본 키 정보가 에 DataSetDeleteCommand 있으면 가 자동으로 생성됩니다.
