Hello All! I have a rather abstract question for some genius out
there to answer. I want to integrate communication tracking, for
customer relations, into an existing Access DB. What I was going for
is this...
tblCommunicatio ns trxCommunicatio nThreads
----------------- -----------------------
CommunicationID (PK) CommID1 (FK1)(PK)
ContactID (FK from contact table) CommID2 (FK2)(PK)
Content (text)
Date
Both CommID(s) in trxCommunicatio nThreads will reference a record in
tblCommunicatio ns. The end goal is to be able to store, track, and
display entire communication threads and the contacts that the
communications are from, kind of what you would see right here in
Google except not as robust. When a contact posts a follow-up to
communication1, the follow-up communication, communication2, will be
added to tblCommunicatio ns as a new record and a relationship between
communications 1 and 2 will be recorded in trxCommunicatio nThreads.
The problem is querying these tables in such a way where it will
display all related threads. The first layer is easy of course (i.e.
the first follow-up to an original communication), but it's the
follow-ups to the follow-ups that I can't quite figure out because it
would require some sort of recursive lookup. Is there a way to write
a recursive query? I can crunch through the trx table and create
thread relationships between communications with code, of course, but
it just seems like there should be a more direct way to do this.
I hope I am not being too elusive here. Please let me know if you
need further detail; although, it's hard to put this concept into
writing using only text.
Thanks to anyone that has any ideas. I have some thoughts of my own
but I thought I'd see what the rest of the community has to say about
this sort of thing before I got heavy into building it.

Hi,
I don't think you can make a single query who will return the full thread of
messages.
Instead, I'll suggest you another approach:
Create a temporary table and populate it with all the messages.
This can be done with VBA (creating the temp table, and populate it with the
communications messages, and deleting the table when is no necessary to
display the thread). The table can be created into a external MDB, created
also "on the fly" or on a "per session" basis (to not bloat your main
database with deleted tables).
Another approach, which will allow you to get all messages from a
communication with a query will involve a different data structure.
You'll need to have a threads table (you'll add there a record for each new
communication thread started). Then for each message it will have two
foreign keys: Thread ID and ParentMessageID . Also you can assign message
order ID for each message in the thread (actually this can be a timestamp
field), and with a single query you'll be able to retrieve all messages from
a given thread.
If you need any more help on this, you can contact me back.
Regards,
Bogdan Zamfir
