HOWTO: Run Singleton SELECT Queries in a Visual Basic Client

This article demonstrates how to retrieve a single record from SQL Server by using the IRow interface with a singleton SELECT. The main purpose for this technique is to avoid the overhead of creating a recordset when you are fetching a single record. Because no recordset is actually created, only one read-only ADODB.Record is returned. This is true even if the specified SELECT results in multiple records being returned if a normal ADODB.Recordset is used.

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;
