hellowangzhi,

I would like to ask, how to achieve join connection for more than 2 DataSets?

If all the datasets have exactly the same structure, then you can use the "set of datasets" form of JOIN (the second form here: https://hpccsystems.com/training/documentation/ecl-language-reference/html/JOIN.html).

Otherwise, you'll just need to do multiple JOINs.

HTH,
