answer:There are a lot of trade magazine and user groups. For example, The Processional Association for SQL Server (PASS), which serves the Microsoft SQL Server community, is huge. and SQL Server Pro magazine/website. I’m familiar with those, I am sure there equivalents for the other particular SQLs like Oracle and MySQL. I think journals would be higher up the food chain, for people in computer science who conceive things like SQL. We users are just trying to be as clever as possible with features which were built into the software. But back to your idea – I learn a huge amount from the sources I list above, and much of it comes from people like yourself who are generous enough to share their ideas.
