Join Red Gate for a free seminar on September 20 (the day before SQL Saturday San Diego). SQL Server MVPs, Steve Jones and Grant Fritchey will present informative sessions featuring best practices for SQL Server database administration, in addition to showing Red Gate tools in action.
Some SQL problems are intriguing because, just when good methods emerge and are accepted, other alternative solutions are discovered. The fun of exploring problems such as 'Gaps and Islands' is all the greater when we have a thorough test-harness to try out the alternative solutions.
Steve Jones notes that SQL Injection is still a problem, and while it might be for some time to come, we should not be adding to the issues. Learn how to write secure code.
