[SwapnaKumari]

Hi,

I am working to create a code which can replace the value of null column with a values of another not null column by using Expression node, but facing challenge. can anyone please help to get the code for this.

Thanks in advance.

Where column1 is the possible null column and column2 is the not null column, try:

If isnull(column1) then
  Column1 = column2
