关于更新？关于这一点，我提出了另一个问题。

OleDbConnection con = new OleDbConnection();
string dbProvider = "PROVIDER=Microsoft.Jet.OLEDB.4.0;";
string dbSource = "Data Source = D:/programming/sample.mdb";
con.ConnectionString = dbProvider + dbSource;
OleDbCommand cmd = new OleDbCommand();
cmd.Connection = con;
cmd.CommandText = "INSERT INTO tblBooks (Title, Price, Tag, Author) VALUES (@title, @price, @tag, @author)";
cmd.Parameters.AddWithValue("@title", "Dummy Text 1");
cmd.Parameters.AddWithValue("@price", 10);
cmd.Parameters.AddWithValue("@tag", "Dummy Text 2");
cmd.Parameters.AddWithValue("@author", "Dummy Text 3");
con.Open();

for (int i = 0; i < 100000; i++)
{
    cmd.ExecuteNonQuery();    
}

 con.Close();

INSERT INTO aTable ( aText, aNumber )
SELECT @param1 , @param2 
FROM Numbers
WHERE Numbers.Number<1000
