Yo, #sqlserver tuners and optimizers, I have a question: under what circumstances would a #queryplan prefer a scan of a clustered index rather than a seek of a non-clustered index with the same predicate and output fields?

I've been pouring over query plans lately, trying to reduce pressure of processes in an environment that sees thousands of processes running, with hundreds at the same time, contending for data access, CPU time, and file locks.

Hey #sqlfamily , curious how everybody is doing Ci/CD. I want to do it. I’ve checked in everything in prod into GitHub. I have access to GitHub Actions. But what do people do to get from dev to prod? If I change a table and add a permission, what scripts out the changes from my dev DB? Looks like Sqlpackage and Flyway? If I can’t have the database look like prod (because of extra audit triggers, etc), how should I handle that? Is there a Recommended Best Practice somewhere? #sqlserver
