操作员只能让你rt by one attribute. Often it is necessary to sort by more than one attribute. Adding the ability to sort by multiple attributes would greatly enhance this simple sorting functionality.

    According to the Sort operator info by building a sequnce of Sort operators you can achieve what you whant. I have tried it on two attributes and it works fine. You just need to carefully consider the order of the two operators to get the sort you need.

    You are right, however it clutters up your processes pretty quickly if you have to sort to three or even more attributes. Especially if you need to sort, reverse and sort again as necessary for some ETL steps. Unfortuantely the Loop operators don't help as they don't guarantee the order of attributes.

    Greetings,
