I want to show you how just a little neater and tighter code can also run a lot faster. These are some of the instant performance improvements that won’t change a lot of code, won’t generate weeks of testing and validation for your colleagues and can be relatively quick to implement.
But most of all, they’ll make the code prettier and easier to understand for the next person.
We’ll look at common ways that null values, implicit datatype conversions and foreign key constraints can radically affect the performance of your queries. Inspired by an actual client case, where I tuned a 20-hour query down to a few minutes, with only a minor code change.
This presentation is all-code, some execution plans, and no-powerpoint.
