Minimum of date columns

Hello! Help me please!
I have date columns DATE1, DATE2 and DATE3. A need to create new column DATE4 which contains earliest date of the three ones. Missing values must be just ignored.
DATE4 = argmin(DATE1, DATE2, DATE3).
I tried to use math formula node but it supports only integer and double fields.
Thank you in advance and sorry for bad english!

Hi Goger,

You can use the Column Aggregator node for that.

Cheers,
Roland
