setting up if switch

Dear all,

please see attached workflow where I have two tables:

TEST with columns:

customer _id

Customer_StatGroupName

Destination / filter with columns:

key

filter

…

I have to loop for all records from table destination / Filter to set row filter conditions to table TEST.

So in run 1 I filter table TEST to Customer_StatGroupName = a; this runs ok

So in run 2 I filter table TEST to Customer_StatGroupName = b; this runs ok

I would like to except when filter condition = *

In this case no filtering is required; all records should been shown

test 7 to Knime.knwf

.

In general row filter node should only be executed when filtercondition != *.

I tried with If Switch / End Switch but unsuccessfully.

Do you have any hint for me?

Thx for help!

BR,

Heinz
