Joiner with two conditions

Hi together,
my file has two tabs, “Input” and “Periods”.

I want to attach the “Wished Resulut” field from the Periods tab to the “Input” tab.
The criterion should be

  1. The date (Date KNIME)
  2. Month 2

I expect that after the joiner node the same amount of data will be contained in the table as at the beginning. Why is this not the case?

Hi @ARock1980 ,

it’s because you are doing a inner join. The missing 5k rows have no correspondence with the right table. It happens with Month 2 = “PY”.

If you test the lenght of “PY” in the second table, it is 3 char long (see below):

After cleaning white spaces, everything seems to work as desired. You can replace the column after using function “stripEnd()”.

Have a nice day,
