I've been working with an SQL database for several years. I use Microsoft Access to generate reports, often building query upon query to pull the data I need.
I'd love to have some SQL select statement training so that I can use nested select statements to generate the data. Any training courses I find are either way below my current level of understanding or way over my head. For instance, I don't need a class that explains what a relational database is, how tables are joined, etc. I need to learn the fundamentals of select statement writing.
Anyone have any ideas on where I might find such specific training sources?
