Sum of a Column

Hi Knimers,

would like to seek help. How do you get the total of the column after using GroupBy Node?
Attached is a photo.

I wish to add a row with the Sum of the “Total” column.

Total could be counted in Pivot node but in separate output. If you want it in one table use Concatenate node to join 2 outputs.

pivot is the best option I assume… but you can as well add a column with a fix input such as 1 and do a group by on this… not so elegant but works…:wink:

You could also add in a Math Formula node at the end, and use the COL_MEAN() function on the Total column.


Employ the statistics node and look at overall sum for row.

Hi there,

I just had the same problem. My solution was

  • to append a supportive column and
  • to use a pivot knode

In the pivot knode, you have to use the supportive column as a pivot and go on with your desired group/s and manual aggregation/s.

After that, you can insert a table manipulator knode and add an additional input port there. So you can bring together the pivot table (first output port) and the pivot totals (third output port).
