Index Scans – Good or Bad? Lots of people ask about this question and I have built a blog post on the topic – SQL SERVER – Index Scans are Not Always Bad. I got lots of good responses and feedback on this blog post. Lots of people asked me to create a video on the topic so here is the video.
So if you were wondering Index Scans – Good or Bad? – It is clear from the video that not always Index scan is bad. It may be just a required operation for the query.
