I'm lokking for a way to select all distinct values of all the attributes in a table.
For exemple :
City / Color
-------------------
New-York / red
New-York / blue
Berlin / yellow
Chisinau / red
Chisiau / blue
and the answer would be "New-York Belin Chisinau" and "red blue yellow"... That could be writen in an excel file or txt...
It's more or less the same action than an advanced filter in excel...
Does anyone know how to do that ?
thank's in advance

A simple sampler with your attributes in the group by setting will provide your desired result.
The Sampler is a good choice as Itay mentioned.
Alternatively, the DuplicateRemover also can be used. To get distinct city names for example, specify "City" to the "Key Attributes" parameter and collect output features from UNIQUE port.
If you need to get finally a concatenated string like "New-York Berlin Chisinau", consider creating a list and concatenating elements of the list after sampling. The ListBuilder or the AttributeAccumulator creates a list, and the ListConcatenator concatenates the elements. Or, the Aggregator does both of creating list and concatenating the elements.
