Hi All,

I have an excel file with header-1 names and header-2 names. I have used AttributeSplitter and made list for both like header-1_list and header-2_list for each record. Now I want to aggregate the values like mentioned below...

If 1 record in excel contains

header-1_list contains 0,1,2 values

header-2_list contains A,B,C,D,E values

Output should be 15 records which contains 0-A,0-B,0-C,0-D,0-E,1-A,1-B,1-C,1-D,1-E,2-A,2-B,2-C,2-D,2-E as values.

(I have attached sample excel file and my progress work bench to this message for better understanding)

Thank you in advance

Pratap

 

Hi @pratap, I would use the InlineQuerier to perform CROSS JOIN.

SQL statement:

select t1.h||'-'||t2.h as header
from t1 cross join t2

Hi @takashi,

Thank you for the reply, it suits exactly the requirement.

Is it possible to add the xlsx_row_id or unique number to each record?

There are several records as shown in excel file and I want to know which records (of target) represent for which record (of source i.e. xlsx_row_id)...

Thank you once again,

Pratap

In the second approach, the original "xlsx_row_id" attribute will be propagated to the resulting features naturally. Just expose it in the reader feature type.

 

Thanks @takashi, I got it with another approach with feature Merger.

cross join is just a unconditional featuremerge...also known as a certesian product
