Hi I usually hunt the net and sleep on things until I find the answer but the following seemingly simple problem is completely evading me.

I have 2 tables,

TBL_Incidents

IncidentID
IncidentDate
IncidentReportedBy
IncidentDescription

and TBL_Comments

CommentID
CommentFromUser
Comment

There are multiple comments per incident.

I’d like to get all information from TBL_Incidents where any of the incident’s comments come from a particular user.

All the joins I’ve tried duplicate the incidents, including the left join that I was sure would have worked, e.g.

IncidentID | IncidentDate (+ all other TBL_Incident fields) | CommentID
4 | ... | 2
4 | ... | 3
4 | ... | 5
9 | ... | 12
9 | ... | 13

It’s like I want to use a group by on the Incident ID, but then it won’t give me the rest of the info from TBL_Incidents because they’re not in the group by clause.

a) does anyone have any idea what I’m babbling on about?

b) does anyone know whether it’s possible?

Many thanks.

    I don’t see where Incidents and Comments are related. Is there an IncidentID in TBL_Comments? If so, then you would join on IncidentID and filter on CommentFromUser like so:

    SELECT *
FROM TBL_Incidents JOIN TBL_Comments ON TBL_Incidents.IncidentID = TBL_Comments.IncidentID
WHERE TBL_Comments.CommentFromUser = UserID

    If there is no IncidentID in TBL_Comments then there is not enough information available to link them together…

    Minor reading comprehension fail edit:

    Assuming you’ve got the ID and you’re just combatting duplicates, slap a DISTINCT on there:

    SELECT DISTINCT TBL_Incidents.*
    FROM TBL_Incidents JOIN TBL_Comments ON TBL_Incidents.IncidentID = TBL_Comments.IncidentID
    WHERE TBL_Comments.CommentFromUser = UserID
