SQLUG, Local community edition med Daniel Hutmacher och Magnus Ahlkvist

Det har blivit dags för SQLUG Local community edition igen. Det var några år sen sist. Talare den här gången är Daniel Hutmacher och Magnus Ahlkvist.
Daniel och Magnus kommer att vara i Stockholm, i B3s lokaler. Som vanligt streamar vi till några andra orter också. Den här gången Göteborg, Malmö och Helsingborg.

Getting your ducks in a row – understanding ordered data flows, with Daniel Hutmacher
There’s a lot of information out there to overwhelm you when it comes to performance tuning your queries. It’s very easy to feel like you’re drinking from a fire hose when you’re reading long blog posts or listening to technical conference sessions. Operators, metrics, wait statistics, page life expectancy, parallellism and fragmentation.
But let’s take a step back and understand the one fundamental principle of querying data – ordering. This session is all about interactively and visually explaining the flow of data in terms of ordering, and how that affects the performance of your queries and server.
Once you get these basics right, tuning will feel so much easier and execution plans may even start to appear quite intuitive.

RBAR bad. Sets good, with Magnus Ahlkvist
In this session, I will go over some way too common uses of RBAR (Row by Agonizing Row) processing and show different examples of how they can be replaced with a set based approach. We will look at performance comparisons and talk about code maintainability.
Most of the examples are war stories from my 20 years working with databases. Unfortunately, many of the bad examples come from my own code. Fortunately, many of the good examples also comes from my own code, fixing the bad code.
