InsertCommand Property

IDbDataAdapter.InsertCommand Property


Gets or sets an SQL statement used to insert new records into the data source.

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

IDbCommand InsertCommand { get; set; }

Property Value

Type: System.Data.IDbCommand

An IDbCommand used during Update to insert records in the data source for new rows in the data set.

During Update, if this property is not set and primary key information is present in the DataSet, the InsertCommand can be generated automatically if you set the SelectCommand property of a .NET Framework data provider. Then, any additional commands that you do not set are generated by the CommandBuilder. This generation logic requires key column information to be present in the DataSet. For more information see Generating Commands with CommandBuilders.

When InsertCommand is assigned to a previously created IDbCommand, the IDbCommand is not cloned. The InsertCommand maintains a reference to the previously created IDbCommand object.


If execution of this command returns rows, these rows may be added to the DataSet depending on how you set the UpdatedRowSource property of the IDbCommand object.

The following example creates an instance of the inherited OleDbDataAdapter class, and sets the SelectCommand and InsertCommand properties. It assumes you have already created an OleDbConnection object.

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);

        "CustomerID", OleDbType.Char, 5, "CustomerID");
        "CompanyName", OleDbType.VarChar, 40, "CompanyName");

    adapter.InsertCommand = command;
    return adapter;
