Concatenation in MS Access SQL View

Hello,

I just modified a report in MS Access (2010) originally developed by another (already gone) person.

I inserted a new field to the already existing report, containing various tables. All very simple and it woks perfectly fine. However, when I wanted to concatenate the results of that field into one row I just Couldn't!!! I tried several functions and even tried the listagg function that works for Oracle 11.2g (which we have), but no luck.

Since the report  is based on Access' SQL View and not in VBA, I had to go to that view to manually try to insert a concatenating function, but none of them seem to be supported.

When I run the query this is what I get:

NAME             TRACKER
John Doe         SKS
John Doe         LHN
John Doe         JM

What I would like to see, as you probably now, is:
NAME             TRACKER
John Doe        SKS, LHN, JM

Is there a way to do it in Access by using the SQL view at all? Is there another way?
Please help!!! I am stuck here.

Thanks

Similar technique with a detailed explanation and custom aggregate function for concatenating records by group, written by matthewspatrick here:

<<Is there a way to do it in Access by using the SQL view at all? Is there another way?>>

There is no native method to do this in Access SQL, as there may be in Oracle or other database platforms, so the workaround is to use custom VBA functions and include those functions in your queries.

Hello capricorn1 and mbizup!!
Thanks for your quick answer. I apologize I didn't answered before, but work has been crazy and I hadn't had the chance to try out your solutions.

I am working on them today and I will get back to you to let you know what I did.
I have to say that these solutions look pretty awesome and just probably what I needed.

Thanks a lot again.

Wow! I tried both solutions and both worked out well for my issue.
I have to say that I am very impressed since I have never expected this could be done this way.

I like mbizup's detailed solution, but also I like capricorn1's concise solution.

Thanks a million guys!!
