Window functions will always have a special place in my heart as one of the magic moments on StackExchange where I discovered something truly powerful. Many years ago I had been asked as a lowly developer to perform some sort of reasonably complex dimensional reshape on a SQL Server table. I was at a loss so I asked on DBA StackExchange for advice and I got a response providing a glorious 4 line window function that gave me exactly what I needed. It really made me excited about diving deeper into SQL and motivated me enough to become quite good at it. It’s ended up being one of the most invaluable skills to have learned during my engineering career.
