Building reusable table build scripts using SQL Prompt

You need a fast, general-purpose way to save the results of a query or batch or procedure into any sort of worktable, such as a temporary table or a table variable or table valued parameter. A simple SELECT…INTO isn't versatile enough for these requirements, and the alternative ways to handcraft the list of columns are slow and error prone. Phil Factor shows how to create a 'table-build generator' that will do all this, and save you a lot of time, especially if you use a lot of working tables in your code.

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;
