매개변수를 사용하여 OleDb 테이블을 효과적으로 업데이트하는 방법은 무엇입니까?

using (OleDbConnection conn = new OleDbConnection(connString))
{
    conn.Open();
    OleDbCommand cmd = conn.CreateCommand();

    // Create OleDbParameters for each field
    OleDbParameter paramMName = new OleDbParameter("@MName", customer.MName);
    OleDbParameter paramDesc = new OleDbParameter("@Desc", customer.Desc);

    // Add parameters to command object
    cmd.Parameters.Add(paramMName);
    cmd.Parameters.Add(paramDesc);

    // Construct SQL query with parameter placeholders
    cmd.CommandText = "UPDATE Master_Accounts SET M_Name=@MName, Desc=@Desc WHERE LM_code=@LM_code";

    // Execute update using parameters
    cmd.ExecuteNonQuery();
}
