Assembly:

System.Data.OleDb.dll

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

Property Value

OleDbCommand

An OleDbCommand used during Update(DataSet) to insert records in the data source that correspond to new rows in the DataSet.

Examples

The following example creates an OleDbDataAdapter and sets the SelectCommand and InsertCommand properties. It assumes that you have already created an OleDbConnection object.

C#

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;
}

Remarks

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 and use the OleDbCommandBuilder. Then, any additional commands that you do not set are generated by the OleDbCommandBuilder. 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 OleDbCommand, the OleDbCommand is not cloned. The InsertCommand maintains a reference to the previously created OleDbCommand object.

Note

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 OleDbCommand object.
