Your articles are always inspiring, thank you for helping those of us trying to learn.

I have three tables, fieldnames & records simplified for brevity:

[Athletes]

ID Athlete
1 Athlete1
2 Athlete2
3 Athlete3
4 Athlete4

[Events]

ID Event
1 Event1
2 Event2
3 Event3
4 Event4

[SummaryData]

ID Event Athlete
1 1 1
2 1 2
3 2 1
4 2 3
5 3 1
6 3 3
7 3 4

I want to select one or more Events from [SummaryData] and only get Athletes that were in both Events,

eg:

Events 1 & 2 had only Athlete1
Events 2 & 3 had Athlete1 + Athlete3

Please help me in the right direction. What sort of join is simplest and most efficient in achieving this?

Thank you in advance, Peter

I have been benefiting from your blog from years and I just thought that how callous I am that never appreciated your efforts. Thus, I am writing these line to thank you for sharing all this knowledge with us.

Thanks,
Rao
