Denny Figuerres

I started with computers about 24 years back. First PC was a Commodore VIC 20 and my “Mass Storage” was a cassette tape deck from my stereo gear with a home made A/D converter built from a 555 timer IC. I have worked at a large ISP for several years www.inreach.com based in Stockton California, I was there with the founder John Keagy in the 95-98 time frame when it went from 2,000 subs to 30,000 subs. I ran the support desk for a while and then the IT support including the adoption of RadiusNT form IEA software that logged dialup use form the modem banks to the tune of about 6 million SQL database records per month using SQL 6.5. For the last 4 years I have been working with a Billing and Ops’ system company www.internetsupportsystems.com in florida; I also do custom stuff for different folks in the local area. I have spent many hours with many levels of engineers from Cisco and Motorola. For a while I was on the IETF “Anti Spam Working Group”. I heard a lot of ideas about spam and was able to make some good points about the problem of the internet and the way things work.

Question of the Day

How Many Can Be the Greatest

I am trying to analyze a number of columns in a large table to determine the highest value for each row. In SQL Server 2022, we have the GREATEST function, which will return the greatest value from those columns passed in. How many columns can I include in an expression like this: 

select GREATEST( col1, col2, col3, ...)
