if condition

Dear all,

I have a table with two fields:

field1

field2

I try to realize the following metacode:

if field2 = null (missing value) then

field2 = field1

else

field2 = field2

endif

I tried with node column expression without success:

if

column(“field2”) = null

{

column(“field1”)

}

else

{

column(“field2”)

}

replacing column field2

Where is my fault? Knime is not happy with the compare line…

Thx for help!

BR, Heinz
