Structured Query Language (SQL) is a coding language used by programmers to store data and manage relational databases. Computer scientists at IBM introduced SQL in the 1970s with the intention of using the language to manipulate and retrieve data stored in System R, a quasi-relational database management system IBM was using. With SQL, programmers could now access many records with a single command and no longer needed to specify how to reach a record. By the mid to late 1980s, SQL became a standard of the American National Standards Institute and the International Organization for Standardization.

SQL is one of the most popular languages used by beginners. The language has a simple and intuitive syntax, making it easier to learn than some other programming languages. Beginners also like seeing immediate results of their queries when using SQL and find the language accessible compared to others. Today, programmers and developers use SQL to create and update databases, as well as identify patterns and analyze data.

What Can You Do with SQL Training?

Back-end web developers use SQL to communicate with databases. With SQL, they can carry out commands like UPDATE, DELETE, and DROP. SQL integrates with Python and R, which is useful in areas like web development and data analysis. Professionals working in the field of data science rely on SQL to integrate data that they plan to analyze and propose data-driven decisions on.

The way you use SQL will depend on your programming or development objectives. With SQL, you can manipulate data contained within tables by changing data points or altering sections of the table. You can also build new databases, retrieve data, change data structures, and define database schema with the programming language. Data scientists, data administrators, and business intelligence developers use SQL for these purposes and others.

What Will I Learn in an SQL Class?

An SQL class will teach you the foundations of SQL through hands-on lessons and projects. Take an SQL class if you want to prepare for a career in data science, programming, or development. You can expect to learn about SQL queries, SQL Server, PostgreSQL, and data analysis in an SQL class. Projects and activities that you complete with classmates will also help you develop strong communication skills that will come in handy in your professional career.

SQL Queries

SQL queries, or SQL statements, provide instructions for relational databases. Think of them as commands that you’re sending to a database requesting the database to send you data. For example, you might run SELECT to select data from a database and SELECT DISTINCT to retrieve distinct values from a database. Most beginner-level SQL classes begin with lessons on how to use SQL to query a database. If you’re working with data, you must understand how to retrieve data. With SQL queries, SQL users can modify data, aggregate data for analysis, and connect databases to applications.

SQL Server

Microsoft SQL Server is the company’s relational database management system that performs SQL queries and commands. Specifically, SQL Server allows software applications to request data. Microsoft introduced SQL Server in 1989. Today, users can purchase a subscription to SQL Server, with options for mainstream or specialized editions available. Data scientists, system architects, and even financial analysts use SQL Server to retrieve and analyze data.

PostgreSQL

PostgreSQL, like SQL Server, is a relational database management system. With this free and open-source database, users can define custom data types and integrate the system with other database systems, like MySQL, Oracle, and SQL Server. Many professionals use PostgreSQL because it’s a cost-effective system that strongly complies with SQL standards. Enrolling in an SQL program will help you understand how and when to use PostgreSQL versus SQL Server.

Data Analysis

Data analysts use SQL to access and manage data. SQL’s simple syntax and ability to perform complex data analysis through interactions with large datasets make the language valuable to data professionals. With SQL, users can create advanced tools and dashboards; those dashboards can then help display data for ease of analysis. Users can also integrate data analytics into other frameworks. You can learn data analysis in a class or bootcamp focused on SQL for data analysis.

Communication

You need strong communication skills to excel in a lot of roles. Whether you want to become a Data Scientist, Web Developer, or Financial Analyst, you need to know how to communicate with a team, supervisors, and clients. An SQL course will help you develop strong written and oral communication skills. You’ll work on projects that will emphasize working with others, writing reports, and presenting findings—all important skills for working in a team-based environment.

How Hard is It to Learn SQL?

Many people find SQL to be a fairly easy programming language to learn. The most challenging aspects of learning SQL are understanding the concept of using a programming language and learning how to use different SQL relational database management systems.

Individuals with no prior programming experience sometimes find it difficult to understand how to work with a new, unspoken language. Taking your time to learn the basics of SQL like vocabulary and queries is an important foundation that will make learning SQL easier in the long run.

You have a lot of options when it comes to SQL relational database management systems. The difficulty for most learners is understanding the differences between them. Many of these systems have differences that users find hard to remember, like the different commands or even the difference in punctuation between commands. Starting small and learning widely used systems like SQL Server and PostgreSQL first can help you pick up other systems more easily later on.

How Long Does It Take to Learn SQL?

You can learn the basics of SQL in about two to three weeks. This includes learning basic syntax and commands, simple queries, and aggregate functions. SQL’s commands follow basic English, so most people find the language itself easy to pick up. Intermediate-level skills take around one to three months for most learners to develop. After those one to three months of training, you should know how to perform subqueries and aggregate data. If you’re aiming to learn advanced-level SQL, expect to spend about three to six months, possibly more, learning advanced-level topics such as performance optimization and database design.

Your prior experience with coding languages and your objectives in learning SQL will likely influence how long it takes you to learn. If you have no prior experience, you may need more lessons and practice than someone who has coded before. If you plan on applying your SQL skills to real-world projects, the process of developing advanced-level skills may take longer than usual expectations. However, even with no prior experience, you can learn SQL fairly quickly with enough dedicated practice and training.

Should I Learn SQL in Person or Online?

Ready to enroll in SQL training? Schools and training centers that offer SQL training typically provide a mix of in-person, live online, and asynchronous classes. Consider your schedule, your learning style, and your objectives before enrolling in any specific class type.

In-person classes held by schools and centers take place during the week, in the evenings, and on weekends. This style of class requires students to commute to a classroom or computer lab, so you should prepare yourself for commuting if you enroll in an in-person class. Most students like learning face-to-face when possible, and in-person classes provide familiarity for beginner students thanks to their traditional style. The cost of attending an in-person SQL class will vary depending on whether you’re enrolling in a short program, a bootcamp, or a certificate program, with single to week-long classes usually costing several hundred dollars, bootcamps costing several thousand, and certificate programs costing several thousand or even tens of thousands of dollars.

Demand for online learning has increased the popularity of online SQL classes. Many schools that offer in-person classes also offer online classes. You can find live online SQL classes for beginners that will walk you through beginner, intermediate, and advanced-level SQL. In a live online class, you’ll learn from a live instructor via a web conferencing platform, like Zoom. You’ll have the chance to ask questions, receive feedback, and share your screen. Students who can’t commute to an in-person class but want the experience of learning from a live instructor can do so in this style of class. Most live online programs cost the same as their in-person counterparts.

If you can’t attend a scheduled class, you can enroll in an asynchronous class. Asynchronous classes, also known as on-demand classes, don’t follow a scheduled curriculum. Instead, students will enter a virtual classroom where they’ll have access to class materials like pre-recorded video lectures and activities. Asynchronous classes usually cost significantly less than live classes because they don’t include access to an instructor. Students will instead work through the material on their own, so it’s important that if you plan on enrolling in an asynchronous class, you can motivate yourself and self-teach.

Can I Learn SQL Free Online?

The internet provides great resources for learning the basics of SQL for free. Online learning platforms like Udemy and Coursera offer short-form on-demand classes where you can learn the foundations of SQL without paying for formal training. Training centers and schools also frequently upload video lectures to YouTube, sometimes in a series format, that help beginners learn the basics of SQL. Students who turn to the internet to learn what they can about SQL for free can also depend on forums where SQL users meet to discuss topics and ask each other questions when they’re stuck on something. Formal training is usually the next step after learning the basics of SQL for free online.

What Should I Learn Alongside SQL?

Learning SQL can open you up to a world of new skills and possible career paths, including web development, data analysis, and programming. Many students learn other popular programming languages when learning SQL.

If you want to use your SQL knowledge to develop websites, consider learning back-end or full-stack web development. Back-end web developers work on the back-end, or server-side, of websites and applications, managing databases and ensuring functionality. Full-stack web developers work on the back-end of websites and applications as well as the front-end, or client-side. A Web Developer working on the back-end usually needs to know several programming languages, including SQL, Python, and Java. You can learn these other coding languages in a back-end or full-stack web development class, or you can enroll in a class focused solely on one of several coding languages.

Another useful skill to learn when learning SQL is data visualization. With SQL, users can retrieve and manipulate data that they plan to use in their visualizations. The actual data visualization process involves simplifying complex data, identifying trends, and creating visually appealing graphics that engage viewers. While you won’t use SQL to create data visualizations, it's crucial for preparing and combining data. You can then integrate SQL with data visualization tools like Power BI and Tableau to help make the visualizations.
