Many SQL intro/fundamentals classes only teach you about the language elements and how to use them. However, not focusing on their mathematical roots or why the language elements were designed the way they were designed. This course teaches you both.


Discover how to:

  • Go beyond traditional query approaches to express set calculations more efficiently
  • Delve into ordered set functions such as rank, distribution, and offset
  • Implement hypothetical set and inverse distribution functions in standard SQL
  • Use strategies for improving sequencing, paging, filtering, and pivoting
  • Increase query speed using partitioning, ordering, and coverage indexing
  • Apply new optimization iterators such as Window Spool
  • Handle common issues such as running totals, intervals, medians, and gaps
