"Database Administrator" for a small Insurance Broker in England.

I use the quotes as, being a small business, although my role is called Database Administrator, you often need to be a jack of all trades for small companies. As a result I have exposure to Network Administration, Web Development, and some server maintenance (mainly the Ubuntu servers at the office); so although I'm not trained I've had to assist enough times to know what I'm looking for or at (which greatly helps when a problem isn't SQL Server based).

SQL Server enthusiast, however, little to no experience on with any other RDBMS. Linux and Windows user, with VB.Net experience, and enjoy to dabble in PoSH and Bash. I can read C#, it is a .Net language after all, but I'm hopeless at writing it; for some reason it's always escaped my grasp. I can't even blame it on the compulsory semi-colons as (one day) they'll be compulsory in T-SQL too (bring it on SQL Server 2037!).

Question of the Day

The LAGging NULL

I have this data in a SQL Server 2022 table: 

player         yearid team HR
Alex Rodriguez 2012   NYY  18
Alex Rodriguez 2013   NYY  7
Alex Rodriguez 2014   NYY  NULL
Alex Rodriguez 2015   NYY  12
Alex Rodriguez 2016   NYY  9
If I run this code, what are the results returned in the hrgrowth column? 
SELECT
  player
, yearid
, hr
, hr - LAG (hr, 1, 0) IGNORE NULLS OVER (ORDER BY yearid) AS hrgrowth
FROM dbo.playerstats;
