Due to SQL’s effectiveness with large amounts of data, you can find it utilized heavily in many attractive software engineering, data science, data engineering, and data analytics positions. SQL Server has become the most preferred tool for processing data, mainly because it can handle a large pool of data and makes it easier to implement the mechanism of a relational database management system. In this SQL Server tutorials blog, we begin with discussing what Microsoft SQL server is, its uses, and share a few but popular SQL commands. We hope this blog has helped you understand SQL Server, its functionality and core concepts more clearly and brought you an inch closer to becoming a successful SQL Developer or SQL Server DBA.
Stay tuned for the last post in this new series where I’ll share my favorite and recommended SQL Server training resources. Welcome to part 2 of my series reviewing my first year as a DBA. Maybe, just maybe, I’ll have enough knowledge internalized by exam time to pass, but I’m not going to be terribly disappointed if I don’t. This is just another step on the journey to becoming a better DBA. Since promotion day, I’ve added three more daily clients to my routine. Each new client brings another level of complexity and new experiences—including one client using replication, and another using Availability Groups.

One of the best things you can do is jump on Twitter and follow the #sqlhelp and #sqlfamily hashtags to find some of the best minds in the SQL community.

Lastly, Kevin and I sometimes have to use shared VPN login credentials (not optimal!), and we’ve learned that there can be trouble connecting to a VPN if the other user was recently connected. We’re not absolutely sure of the cause, but we suspect that it has something to do with IP addresses since we live in different locations. The VPN seems to possibly reject an IP address if the other user had been connected .
Projects are a fantastic way to showcase and improve your skills and make for a great talking point in a job interview. Next, I’ll describe a checklist of SQL topics you should expect to learn to be proficient in the language and interviews. Write a query to find how many missing values are in a table column. This course is one of the few self-contained resources that describes the performance issues you’ll run into when working on larger, more complex databases. If you’d prefer learning SQL through Oracle, the instructor for this course provides a great intro into structuring queries properly and the tools required to work with Oracle effectively. Dataquest offers a certificate for every course or path completed, but certificates issued might not be considered credible by employers.

SET and SELECT have different results, based on what you need to do. Check out Optimizing Transact-SQL Code, by Kevin Kline and Baya Pavliashvili. They show you the best way to use variables in writing cursors. A simple example, no doubt, but an adjustment to fill the initial variable with something https://remotemode.net/ meaningful and a change between the BEGIN and END markers would make this a useful bit of code. The neat thing about these variables is that are stored completely in memory. Unless, of course, the server is out of memory, and then of course the whole thing is stored in TEMPDB on the hard drive.
Inside SQL Server’s architecture — How SQL Server works
Doug Lane delivered a free course on the leading SQL Server performance tuning company “Brent Ozar Unlimited”. It is designed for junior SQL Server developers and application developers who want to improve their T-SQL skills. It covers several topics such as thinking in sets, CASE expressions, computed columns, and windowing functions. One of the biggest frustrations I’ve had in self-guided learning is discovering that there’s a ton of simply erroneous information out there related to SQL Server. I can’t tell you how many times I’ve read a blog post or article to eventually find it was just wrong.
