A couple of weeks ago, an interesting discussion popped up on the r/sysadmin subreddit:
"Learning SQL - Yay or Nay? I'm looking into which area I should be studying next and I often see SQL mentioned on job listings. I'd love some advice if it is the correct thing for my current skill set, or If I should be focusing on different skills."
Without interjecting too much of my personal opinion, I thought the commentary was interesting and definitely interjected some considerations I hadn't made before.
While of course it's helpful to know more about nearly any technology you might encounter in your day job, what to learn has to be a matter of priority. But I've always found querying and filtering to be critical: Whether you're using SQL, regular expressions at the command line, or just some basic filters in a spreadsheet, it's essential to know how to break down big piles of data into something digestible, or just find that one thing you need.
But that's just my opinion.
SELECT `opinions`
FROM `sysadmins`
WHERE `topic` = 'querying data';
What do you think? Is learning SQL a critical skill for a sysadmin, a nice-to-have, or not even of real value?
