示例1: MapParameters
/// <summary>
/// This function attempts to map all parameters in the collection to all statements in a Command.
/// Since named parameters may span multiple statements, this function makes sure all statements are bound
/// to the same named parameter. Unnamed parameters are bound in sequence.
/// </summary>
