The big problem is that most Access books are about Access, with a bit of
SQL chucked in. The next problem is that they move into teaching you how to
write SQL, the syntax etc.
I use O'Reilly's Transact-SQL Programming, but that flavour of SQL is
SQL-Server and Sybase specific, so probably doesn't suit.
Martin Green recommends
SQL: Access to SQL Server
Susan Sales Harkins, Martin Reid
Apress ISBN: 1893115305
but that seems more like a migration tome. It sounds that you want to have a
problem solving book that uses SQL as the tool. Maybe
SQL Queries for Mere Mortals (English)
(A Hands-On Guide to Data Manipulation in SQL - ISBN: 0201433362)
Publisher: Addison-Wesley
or
SQL Cookbook
By Anthony Molinaro
or
Access Database Design and Programming, Second Edition
By Steven Roman, Ph.D.
Those are not recommendations, I have only read the one, and I have no
vested interest in any of them.
