  • Could SQL Injection be dangerous even when perfectly safe?
    Despite being one of the oldest database attack methods, SQL Injection still persists for decades at the OWASP Top Ten list of critical security risks to web applications. In fact, instead of dying out, it only seems to be getting more clever and even automated. With “hacker bots” scouring the web and automatically probing for injection vulnerabilities to exploit. But today I’m not actually going to talk about that. Today, I’m going to ask the question: When is SQL Injection dangerous, even if it’s perfectly safe?
  • New Upcoming Session – Troubleshooting Common SSDT Errors
    As a spiritual “part 4” in my ongoing series of webinars titled “CI and CD with SSDT”, I will be delivering an entirely new session called “Troubleshooting Build and Deployment of SSDT Projects for SQL Server DevOps” (or “Troubleshooting Common SSDT Errors” for short).

    One of the things that are not so clear about SSDT specifically and database versioning in general, is how should one identify which “version” of your database project was last deployed to your server? There are many ways to go about doing this. Which is the best one? In this article, I hope to review several interesting methods of achieving “database versioning”. Some are well-known and obvious, and some are less so. Either way, it should be interesting.

    Should your SQL Database project be in the same solution as the App project? Or maybe they should be in the same source control repository but separate solutions? Or maybe they should be in completely separate repositories? Read more to find out!

    A few years ago, I created a couple of T-SQL scripts that can be used for comparing instance-level and database-level properties between two HA/DR replicas. Originally, this supported comparing only two servers. But recently, following a fan request, I upgraded the script to support an unlimited number of servers that you can compare to each other.
