Copy column identified in flow variable to new column



This should really be simple but I cannot seem to work out how to do it - maybe because it is the weekend. I have the name of a column in a flow variable (the actual column can change) and would like to copy the contents of that column to one with a defined name. The Math Formula node does not seem to allow dynamic access to columns so I have been trying using a Java Snippet but cannot get it to work (probably due to the fact that I am not a java programmer).


I have been trying to use getCell as in:

and keep getting a 'the method is undefined' error using like this. However, I cannot work out what getCell is a method of in the Java snippet.
I would be very grateful if someone could let meknow how I should be using this - or even if there is a better way to achieve the same thing than using a java snippet.

You can use the rule engine node to this. Simply make the variable setting in the outcome box of the rule engine node. I think you may need to append dollar signs to either end of the column name first.


Thanks for the advice. Never used that node before but it worked like a charm.



Also the Column Merger seems like it would be appropriate no?
