Property Value

An OleDbCommand that is used during Fill to select records from data source for placement in the DataSet.

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

If the SelectCommand returns no rows, no tables are added to the DataSet, and no exception is raised.

The following example creates an OleDbDataAdapter and sets the SelectCommand and InsertCommand properties. It assumes that 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 * 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;
