Searching for teaching material / books on advanced SQL for Access (1 Viewer)

[KirRoyale]

Apologies if this is the wrong forum ….After a few months of grappling with Access, working through books and getting help on this site (and other internet resources), I’m finding that solving query problems is my main issue.
Could somebody please recommend a good ‘Advanced SQL for Access’ book / resource?

I don't know what "advanced" mean . For me this TUTORIAL is very advanced.

Thank you, Mihail.
