IDbDataAdapter.InsertCommand 屬性

public:
 property System::Data::IDbCommand ^ InsertCommand { System::Data::IDbCommand ^ get(); void set(System::Data::IDbCommand ^ value); };

public System.Data.IDbCommand? InsertCommand { get; set; }

public System.Data.IDbCommand InsertCommand { get; set; }

member this.InsertCommand : System.Data.IDbCommand with get, set

Public Property InsertCommand As IDbCommand

屬性值

IDbCommand，在 Update(DataSet) 期間用來為資料集中新的資料列插入在資料來源中的資料錄。

範例

下列範例會建立繼承 OleDbDataAdapter 類別的實例，並設定 SelectCommand 和 InsertCommand 屬性。 它假設您已經建立 OleDbConnection 物件。

public static OleDbDataAdapter CreateCustomerAdapter(
    OleDbConnection connection)
{
    OleDbDataAdapter adapter = new OleDbDataAdapter();
    OleDbCommand command;

    // 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);

    adapter.SelectCommand = command;

    // Create the InsertCommand.
    command = new OleDbCommand(
        "INSERT INTO Customers (CustomerID, CompanyName) " +
        "VALUES (?, ?)", connection);

    command.Parameters.Add(
        "CustomerID", OleDbType.Char, 5, "CustomerID");
    command.Parameters.Add(
        "CompanyName", OleDbType.VarChar, 40, "CompanyName");

    adapter.InsertCommand = command;
    return adapter;
}

Public Shared Function CreateCustomerAdapter( _
    connection As OleDbConnection) As OleDbDataAdapter 
  
    Dim adapter As New OleDbDataAdapter()
    Dim command As OleDbCommand

    ' 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)

    adapter.SelectCommand = command

    ' Create the InsertCommand.
    command = New OleDbCommand( _
        "INSERT INTO Customers (CustomerID, CompanyName) " & _
        "VALUES (?, ?)", connection)

    command.Parameters.Add( _
        "CustomerID", OleDbType.Char, 5, "CustomerID")
    command.Parameters.Add( _
        "CompanyName", OleDbType.VarChar, 40, "CompanyName")

    adapter.InsertCommand = command
    Return adapter
End Function

備註

在 期間Update，如果未設定此屬性，而且主鍵資訊存在於 中DataSet，InsertCommand則如果您設定 SelectCommand .NET Framework 資料提供者的 屬性，則可以自動產生 。 然後，您未設定的任何其他命令都會由 CommandBuilder 產生。 此產生邏輯需要中 DataSet存在索引鍵數據行資訊。 如需詳細資訊，請參閱 使用 CommandBuilders 產生命令。

當 指定先前建立IDbCommand的時InsertCommand，IDbCommand不會複製 。 會 InsertCommand 維護先前建立 IDbCommand 之 對象的參考。
