Migrating my Stack Overflow answers to blog posts (Sorry for the spam)

Mon, 11 Nov 2024 17:21:05 -0500

For a while, I have been thinking about using my Stack Overflow answers (and answers on other sites on the Stack Exchange Network), and storing a copy of them here, on my blog as well. All posts on the Stack Exchange network are covered under the Creative Commons BY-SA license. When Stack Overflow was created, this license was chosen to ensure that Q&A data remained an open data repository. Posts can be freely reused, re-published, etc, so long as attribution is provided (who is the post BY, and where it was published), and derivative versions are also shared under the same license (ie, Share Alike).

T-SQL Tuesday: The last ticket I closed

For this month's T-SQL Tuesday, Brent Ozar (blog|Instagram) asks us to describe the most recent ticket we closed.

“We had a pretty significant wait spike…”

The literal last ticket I closed was “please run this script in production…”, and I don’t think it would be a very interesting blog post to talk about how I copy & pasted a query into SSMS, so let’s talk about a recent ticket instead, from the last couple of weeks.
