Writing advanced SQL how, when and why
Kurt Struyff, Lone Star - Thursday 31 May - Session 2
Writing advanced SQL is, if not an art, at least a professional skill. In this class developers and database administrators will be trained to recognise different ways of coding for the same solution. They will learn how to code the same result differently and why this can be important. When do you use a certain query rather than another, what is “the best” way to code something, how do you know the difference ?
Better known constructs like sub queries are compared, analysed and explained, to inspire new, more efficient ways of coding. We will also cover more complex OLAP queries, SQL PL and much more.
Whether you are a beginner or an experienced developer, whether you are a junior database administrator or a senior system administrator, you will walk away with new ideas.
- understanding sub queries
- exploiting group by and grouping sets
- using Joins and anti-joins
- explaining nested table expressions
- recognizing relational division
- coding correlated table expressions
- working with common table expressions
- understanding recursion
- building OLAP functionality
- harnessing the power of SQL PL
- using temporal table access
- understanding locking and concurrency
- using piece-wise delete and update
