For a long time, I have been seeing the same SQL Server questions come up over and over again on Stack Overflow and Database Administrators. Two decades ago, I started blogging to reduce the amount of work I was doing to help guide users to the right solutions (except, back then, it wasn't Stack Exchange, it was newsgroups and mailing lista).
I took a little break from Q & A this year. When I got back into it more recently, I discovered I was once again scrambling to assemble the right (and most current) links for, say, advising people to stay away from
MERGE. So, I made some landing pages here, with simple and easy-to-remember URLs, presenting a small set of links to further reading on the topic. So far, these are the landing pages I've put together:
Personally, I use a program called Unclutter on my Mac as an effectively infinite clipboard, and have the URLs stored there permanently, even though I doubt I'll ever forget any of these ones. If you find you're searching for a URL more than once, it might be handy to use some kind of productivity app.
