The link Steve Collins posted is interesting. Got through it, and while I don't quite agree that stored procs create a strangler pattern, I do think in the high...

Check out this video.  The speaker gives a whole laundry list of reasons, a litany of epiphanies, on why SQL Server is not well suited for transaction processing.  Instead, the...

It seems you could use COUNT in the SELECT list.  COUNT always returns an INT even if the FROM clause returns no rows

This is interesting.  Nicely done Jeff.  The AI (ChatGPT-4) was unable to make any improvements to the query marked as the solution.  It never comes up with nothing so it...

The prompt was based on minimal code

this sql code omits a 2nd column with which we could order the rows.  Could you add a date column...

Without a second column containing a date (or some ordinal data type) there's no way to ensure the row ordering is consistent.  Thanks ChatGPT for fixing the data.  You could...

No idea what's meant by the rounding.  Presumably (to get the correct output) there's a '<=' inequality.  To handle the range between 174 and 176 you could create a partial...

Here in New Jersey USA it's too nice of a day to sit behind a screen!  Spring fever in full effect here 🙂  After my 2 o'clock meeting... adios
