convert a collection to a single table

acuriel

I'm using loop values and it generates different tables (ExampleSet) by value with the same attributes.
I need to have a single table with all.

my out is

collection

table value 23: 
                  USER_ID  ITEM_ID
                  1          23

table value 54:
              USER_ID  ITEM_ID
                  1          54
...                     

I need this

ExampleSet
 
              USER_ID  ITEM_ID
                  1          23
                  1          54
                  ...        ...

Thanks

assuming all the attributes are exactly the same (type and total number), just add the "APPEND" operator to the output of your loop and they will all be in one table
