Value :: toString - Convert to string value

The function returns the property value as String value. When the property is not a text property the property value is converted into a string value. Large binary fields ( BLOB ) are converted to Base64 strings.

When no instance is selected or the value cannot be converted into a numeric value, the function throws an exception.

Return value:  String value ( odaba::String & )
