all of these are SQL-based database management systems, and that means that SQL skills will be needed to work efficiently with databases at almost any company. MySQL, Oracle, Microsoft SQL Server, etc.
Almost every company uses some kind of SQL-based database to store data.The full article is definitely worth reading, but in case you don’t want to click through, here’s are a few quick reasons: We’ve written a whole article on why you should learn SQL, with up-to-date jobs information from 2021. It’s really only useful for tasks that involve working with data in databases.īut that’s a good thing! Because SQL is specifically focused on working with data, there’s less for you to learn, and most of the SQL educational materials you encounter will be focused on using SQL for common data tasks. SQL isn’t going to be the language you use to do something like code a video game, or build a mobile app. What this means is that SQL isn’t a full-on programming language in the way that Python (for example) is. If you’ve got data that’s stored in a SQL-based database-and you probably do, most companies use some form of SQL-based database management system-SQL is the tool that’ll help you quickly select and work with the specific data you need. Perform calculations, analysis, and filter data to answer questions.Join elements from different data tables in your database together.Get the specific data you want from databases.When you’ve learned SQL, you’ll use it to do things such as: In the previous section, I called it a programming language, but it would be more accurate to say that SQL is a query language.Ī query language is a type of programming language that’s built for one thing: interacting with databases. To understand what it takes to learn SQL, it’s important to understand what SQL actually is. So rather than try to give you a one-size-fits-all answer, we’ve gamed out a number of different scenarios. The answer really depends on you, your goals, and your background. But how long does it take to really learn SQL? And while learning a new programming language is never a walk in the park, we’ve got some good news - it typically doesn’t take too long to get the basics of SQL down. SQL is a critical skill for pretty much anyone who works with data or databases. How long does it really take to learn SQL?
