Best way to return earliest of multiple date fields in Magic ETL


I have a dataset that has five dates... I want to add a new column that contains the earliest of those five dates.  That is easy to do in a MySQL data flow... but I can't figure it out in Magic ETL (I'm just starting to use Magic ETL more as our dataset sizes are growing and Magic ETL seems to be "faster").


Any help would be appreciated.

  • I would suggest you use the collapse columns tile to "pivot" your date columns into a single column and then use the group by tile to get the min of those dates. You can even split your dataset to do these functions and then join it back to your original dataset if you need to use it with the rest of your data. Not sure what you are looking for at the end of the day, but just throwing it out there if you weren't aware you could do that.

    Interesting... I hadn't thought of that technique... I'll give that a try and see how it works.
