Full Abstract:
This presentation is a PRACTICAL, HANDS ON way to SQL performance tuning and SQL improvement. When logically correct SQL will always return and answer, the statement might be expensive or cheap but is quite often suboptimal. This presentation will explain the ground rules to writing performing SQL and has numerous EASY-TO-FIX, REAL LIFE improvements. If you are a developer or a beginning DBA, you’ll gain an understanding to better SQL writing and tuning. If you are a more experienced DBA you’ll get a thorough refresh, learn something new and walk a way with an idea of “how to explain SQL to your developers”.
