You swear nothing has changed, but all of a sudden, out of nowhere, queries that used to be fast are suddenly slow. Even weirder, you take the slow query from the application, run it in SSMS, and it’s totally fast! What’s going on?

In this free Idera Geek Sync session on Wednesday, January 27, you’ll see live demos of the most common culprit: parameter sniffing. You’ll learn how to recognize parameter sniffing when it strikes, understand what causes it, see how to fix it short term with the lowest impact possible, and learn 7 ways to fix it long term.
