This one goes in my “to remember” file.
I created an application to insert records into a database and one of the fields was username. The initial implementation prepended the username with the user’s domain (i.e., “DOMAIN\user”) due to the method used to obtain the username.
After a while I added new functionality to the application that added records in a different way and this time the username was added without the prepended domain name. I wanted to figure out a way to update all the old records with a single query and came up with this:
UPDATE Machines SET UserName = (SUBSTRING(UserName,CHARINDEX(‘\’, UserName) + 1, LEN(UserName) – CHARINDEX(‘\’, UserName) + 1))
WHERE Username LIKE ‘DOMAIN\%’
(Domain name changed to protect the innocent…)
As is usual in cases like this, be careful with update statements. Test well before unleashing on production data.

This past Friday I got a general physical for the first time in many years. (Usually I just find a doctor when I have a specific complaint.) The doctor told me that I have hypertension and wanted to put me on blood pressure meds. I asked him if there was another way and he said he didn’t agree with not going onto meds but he did relent and gave me a one month diet/exercise/supplement plan and said that he wouldn’t agree to no meds unless I promised to follow the plan strictly. If my numbers don’t look better at the end of the month I agreed to start the meds.
Given this background, I started thinking about doing things we know we should be doing but don’t. I know I should have been living healthier for a while but haven’t taken time and steps to make it happen. Now I will do it, but I wonder why we things have to get so bad until we take action. Maybe it doesn’t work this way for everyone…
