pentaho - Pentaho Data integration: "group by" with Concatenate strings separated by ";" instead of ","

Question

I have to concatenate strings from different fields. The output should be all strings in on field seperated by semi-colons.

The "Group by" Transformation step does everything i need to do, but I can only separate them with " " or with tabs or with ",". The strings i need to concat contain "," themselves so i cant use "," to separate them?

Answer 1

The Group By step has a second operation "Concatenate strings separated by" (without the comma). Using that, you can enter the separator in the value column.
