Whether you want to be a data scientist or an engineer, databases will come up at some point. If you want to work in data, you will need to <a href=\"https:\/\/careerkarma.com\/blog\/sql-projects\/\">learn SQL<\/a>.<\/p>\n\n\n\n<p>Structured Query Language, or SQL, gives developers a way to efficiently and securely store their data. SQL is a standard. This means that there are clear instructions on how you should write SQL. SQL powers many aspects of the technologies you use every day. When you sign up to a site like Amazon, your name and email will be stored in a database.<\/p>\n\n\n\n<p>With this in mind, it\u2019s clear that <a href=\"https:\/\/careerkarma.com\/blog\/learn-sql\/\">learning SQL<\/a> can have a major impact on your career in technology. This guide will discuss the best way to <a href=\"https:\/\/careerkarma.com\/blog\/online-sql-courses\/\">learn SQL online<\/a>. We\u2019ll give you a clear roadmap you can use to start your journey of mastering this exciting and powerful technology. Discover more about <a href=\"https:\/\/careerkarma.com\/blog\/online-sql-courses\/\">how to learn SQL<\/a> in the guide below.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-sql\">What is SQL?<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"800\" src=\"https:\/\/careerkarma.com\/blog\/wp-content\/uploads\/2020\/11\/christopher-gower-m_HRfLhgABo-unsplash-1.jpg\" alt=\"A laptop with code on a desk.\" class=\"wp-image-118513\"\/><figcaption>If you want to learn SQL, it is important to enroll in a class to get started.<\/figcaption><\/figure>\n\n\n\n<p>SQL is a technology used to create and manage databases. SQL works with a type of database called a \u201crelational database,\u201d which is a structure of data that has both columns and rows of data. In fact, it is the standard language used to manage relational databases.<\/p>\n\n\n\n<p>Each column in a table stores information about a category of data, such as a name or an email address. A row stores values for a particular entry. So, one row in a database could store a single user\u2019s name and email address.<\/p>\n\n\n\n<p>To understand exactly what SQL is, it is helpful to have a basic understanding of how databases function. If you are a database developer or database administrator, SQL offers a wide range of features that make it a useful language to learn. These include:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Adding, updating, and deleting rows<\/li><li>Creating tables to store information<\/li><li>Modifying tables to change the structure of a database<\/li><li>Retrieving rows from the database<\/li><li>Filtering entries in the database<\/li><\/ul>\n\n\n\n<p>The SQL language has been around since the 1970s and has become a standard database technology. SQL will continue to be relevant in years to come. If you learn SQL, you should be able to apply your SQL skills to various job opportunities for the foreseeable future.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-should-you-learn-sql\">Why Should You Learn SQL?<\/h2>\n\n\n\n<p>SQL is very popular, and there is a multitude of reasons why you should learn SQL. It has many applications in many contexts. Here are just a few of the fields where SQL has become an essential tool:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Finance<\/li><li>Music<\/li><li>Social media<\/li><li>Data analysis<\/li><li>Scientific computing<\/li><li>Web development<\/li><li>Game development<\/li><\/ul>\n\n\n\n<p>The list goes on and on. This language is everywhere. <a href=\"https:\/\/careerkarma.com\/blog\/who-uses-sql\/\">Companies of all sizes use SQL<\/a> for applications large and small. This includes the likes of Adobe, Facebook, LinkedIn, Microsoft, and more. Many of these companies rely on SQL for database design and expect their engineers to learn SQL for database architecture.<\/p>\n\n\n\n<p>SQL is intuitive, practical, and easy to use. Even with no background in technology, you can master the fundamentals of the language. SQL uses a syntax that is very similar to English, which means that learning SQL is a smooth process.<\/p>\n\n\n\n<p>Moreover, the demand for SQL developers is high. The TIOBE Index reports that SQL is the ninth <a href=\"https:\/\/www.tiobe.com\/tiobe-index\/\" target=\"_blank\" rel=\"noopener\" rel=\"nofollow\">most commonly searched<\/a> programming technology on the Internet. This index tracks the most popular coding technologies in the world using data from search engines.<\/p>\n\n\n\n<p>That\u2019s not all. According to the US Bureau of Labor Statistics, computer and information research jobs are expected to grow by <a href=\"https:\/\/www.bls.gov\/ooh\/computer-and-information-technology\/computer-and-information-research-scientists.htm\" target=\"_blank\" rel=\"noopener\" rel=\"nofollow\">22% by 2030<\/a>. This growth is described as \u201cmuch faster than average.\u201d As such, people skilled in SQL and other computer information technologies will have ample job opportunities.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-sql-used-for\">What is SQL Used For?<\/h2>\n\n\n\n<p>SQL is a database system used for storing data that can be retrieved using queries. It is used by programmers and data analysts for a range of purposes, from consumer behavior analysis to web application storage.<\/p>\n\n\n\n<p>Anyone whose job involves data can benefit from SQL. For instance, marketers or financiers can learn how to use SQL to derive insights from data. Overall, SQL is useful across a variety of industries. However, SQL is not just a technology used by programmers.<\/p>\n\n\n\n<p>SQL is the standard when it comes to data storage. This means you\u2019ll find it everywhere that large volumes of data are stored. For instance, a company may use an SQL database to store employee records. Alternatively, an insurance company may keep track of claims using an SQL database. Learning SQL will also allow you to use relational database management systems like MySQL.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-long-does-it-take-to-learn-sql\">How Long Does it Take to Learn SQL?<\/h2>\n\n\n\n<p>Learning the basic SQL concepts can take as short as two to three weeks. However, determining how long it takes to learn SQL depends on your commitment. You should consider how much you want to learn this language and why you are learning it when calculating how long it will take to learn SQL.<\/p>\n\n\n\n<p>For real-world applications and to really make a career out of SQL, you will need to expand your knowledge beyond the basics. Fortunately, you can start with a fundamental understanding and build SQL skills on the job.<\/p>\n\n\n\n<p>How long it takes to learn SQL depends heavily on how you\u2019re learning. A coding bootcamp may help you gain basic knowledge quickly, but you can also learn through an online SQL tutorial and other resources. Let\u2019s take a look at some ways to learn SQL.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-to-learn-sql-fast\">How to Learn SQL Fast<\/h2>\n\n\n\n<p>So far, we\u2019ve discussed the basics of SQL and why you should learn the language, even if you are not a programmer. We have established that it is a valuable language, even if you don\u2019t work in database administration. The next topic we will cover is <a href=\"https:\/\/careerkarma.com\/blog\/sql-skills\/\">how to learn SQL fast<\/a>.<\/p>\n\n\n\n<p>Let\u2019s walk through a few steps you should follow when starting to learn SQL. These steps lay out how to learn SQL fast and ensure that you won\u2019t miss any key points. If you follow these steps, you can develop background knowledge about SQL in order to create basic SQL reports and, with lots of practice, move on to advanced concepts.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-1-start-with-the-fundamentals\">Step 1: Start with the Fundamentals<\/h3>\n\n\n\n<p>While you may have big ideas about how you can use SQL, you need to start small and <a href=\"https:\/\/careerkarma.com\/blog\/sql-terminology\/\">learn SQL basics<\/a> first. Luckily, because SQL is so widely used, there is no shortage of resources you can use to gain basic SQL knowledge.<\/p>\n\n\n\n<p>Your first step should be to explore the syntax of SQL and its queries and commands. Then, once you feel comfortable with those SQL fundamentals, you\u2019ll be ready to start investigating more complex applications. Here are the main topics you should explore as you start your learning journey.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-manipulating-data\">Manipulating Data<\/h4>\n\n\n\n<p>The term \u201cmanipulating data\u201d may be confusing to those who are not familiar with database basics. In simple terms, it means learning how to add, change, and remove data in a database. The first step to mastering SQL is learning how to write an SQL statement. A statement is a simple command sent to the database. The statement instructs a database to perform a certain action.<\/p>\n\n\n\n<p>If you want to learn SQL and how it can be used for manipulating data, here are the main topics and keywords you should learn:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>MERGE statement<\/li><li><a href=\"https:\/\/careerkarma.com\/blog\/sql-update\/\">UPDATE<\/a> statement<\/li><li><a href=\"https:\/\/careerkarma.com\/blog\/sql-insert\/\">INSERT<\/a> statement<\/li><li><a href=\"https:\/\/careerkarma.com\/blog\/sql-delete-row\/\">DELETE<\/a> statement<\/li><li>Data Manipulation Language<\/li><\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-writing-queries\">Writing Queries<\/h4>\n\n\n\n<p>SQL querying skills are an important aspect of learning SQL. SQL allows you to write queries that filter out data based on a set of conditions. For instance, you may only want to search for email addresses that begin with \u201cs\u201d in a database. You should explore how to write SQL queries using the query keywords offered by SQL.<\/p>\n\n\n\n<p>Here are some topics you should explore to develop SQL querying skills:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Database management software<\/li><li>INSERT INTO statement<\/li><li>SELECT, WHERE, LIMIT, and ORDER BY clauses<\/li><li>AND, OR, IN, AND BETWEEN OPERATORS<\/li><li>UPDATE and DELETE statement<\/li><\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-aggregate-function\">Aggregate Function<\/h4>\n\n\n\n<p>As we discussed earlier, SQL is often used for data analysis. As a result, it offers a number of different functions that allow you to perform mathematical operations on the data in a database.<\/p>\n\n\n\n<p>These <a href=\"https:\/\/careerkarma.com\/blog\/sql-if-functions\/\">functions<\/a>, which allow you to retrieve insights based on the data stored in a database, are called \u201caggregate functions.\u201d Here are the five aggregate functions of SQL:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>AVG<\/li><li>MIN<\/li><li>MAX<\/li><li>COUNT<\/li><li>SUM<\/li><\/ul>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-connecting-tables\">Connecting Tables<\/h4>\n\n\n\n<p>In SQL, it is possible to work with multiple tables at the same time and run queries that reference them. In fact, this is an important part of maintaining a well-structured database. Connecting tables allows you to work with multiple sources of data contained within different tables.<\/p>\n\n\n\n<p>Here are the main topics you should learn about when you\u2019re ready to explore connecting tables:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/careerkarma.com\/blog\/sql-outer-join\/\">JOIN<\/a> operator<\/li><li>INNER JOIN<\/li><li>LEFT JOIN<\/li><li>RIGHT JOIN<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-2-work-on-an-sql-project\">Step 2: Work on an SQL Project<\/h3>\n\n\n\n<p>There is no better way to practice SQL code than to work on a real-world project. This allows you to work on SQL projects that interest you instead of projects that are listed in an online SQL course or tutorial.<\/p>\n\n\n\n<p>Once you\u2019ve mastered the fundamentals, start thinking about what you want to do that requires SQL. For example, you may want to build a database for your blog or analyze an interesting dataset you found online. There are endless simple SQL projects that you can practice with. Focusing on SQL projects for beginners will help you build foundational knowledge.<\/p>\n\n\n\n<p>Are you looking for ideas to help you get started? Here are a few that you could explore:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Inventory control management system<\/li><li>Restaurant order management system<\/li><li>Employee records storage system<\/li><li>Airline reservations system<\/li><li>Online shopping cart<\/li><\/ul>\n\n\n\n<p>Instead of building your own database, you could use tools like Kaggle to find a dataset. You can use SQL to analyze the dataset you find. Thankfully, there are a variety of SQL tools online today. Many people use these tools to learn SQL as it is a very popular language.<\/p>\n\n\n\n<p>When it comes to what project to work on, the sky is the limit. Of course, you should start small and focus on simple SQL projects. Make sure you do not take on too many tasks at once. When you feel comfortable, you can scale up your SQL projects to use more queries and more complex SQL commands.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-3-document-your-learning\">Step 3: Document Your Learning<\/h3>\n\n\n\n<p>When learning SQL, it can be tempting to write an elaborate SQL query, download its results, and call it a day. Once you\u2019ve written a query, you\u2019ll have generated the data you need. However, this approach skips one key part of the development process: documentation.<\/p>\n\n\n\n<p>Writing documentation allows you to analyze your findings and test your results. You\u2019ll learn to validate whether an outcome of a query or project was what you expected. When you\u2019re getting started, your documentation can be as simple as taking notes throughout your development process.<\/p>\n\n\n\n<p>Ask yourself questions like: \u201cWhy did I write this query using these statements?\u201d and \u201cIs there a more efficient way to accomplish this task?\u201d These questions will help you flex your learning muscles and keep track of why you have made certain decisions.<\/p>\n\n\n\n<p>WritiWriting documentation can help you reflect on your project. After you\u2019ve written a query, you can go back and read the documentation. This will help you better understand why you approached a problem in a certain way. You\u2019ll be in a good position to evaluate whether the result of your project is, in fact, what you were after.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-4-write-reports\">Step 4: Write Reports<\/h3>\n\n\n\n<p>Writing reports is a more intensive way of documenting your work, but it is an important part of working with SQL. You\u2019ll have everything you need to write an insightful report on your findings once you have written a query.<\/p>\n\n\n\n<p>Reports serve a couple of purposes. In a professional development environment, managers and data analysts prefer to work with reports after a dataset has been analyzed. This is because reports are written in a way that allows anyone with the relevant knowledge to understand their contents. You don\u2019t usually need to have SQL experience to read a report.<\/p>\n\n\n\n<p>Businesses rely on reports from their engineers and data analysts to make decisions. As such, these reports often play a crucial role in the direction a business takes. Writing reports can help you refine your thinking about a particular problem. If you want to learn SQL, you also need to put time into learning how to write effective reports.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-5-share-your-work\">Step 5: Share Your Work<\/h3>\n\n\n\n<p>Documenting your work lets you seek feedback from other people. There are a couple of ways to share your work when learning SQL. If you are using SQL on the job, you may want to seek feedback on your work from co-workers. Alternatively, you may want to write a series of blog posts to hold yourself accountable while you work on an SQL project.<\/p>\n\n\n\n<p>Blogs are a great way to share your work because anyone can read them at any time. People who are just starting to learn SQL could come across your post and use it to learn. Alternatively, an SQL expert could land on your page because they are stuck with a problem. They might reach out with a few comments on how to improve your work.<\/p>\n\n\n\n<p>Even a recruiter or a hiring manager could read your blog. They could help you break into a career in tech if you\u2019re not already in a technical position. If you\u2019re not ready to start a blog, you could also share your queries and projects in a <a href=\"https:\/\/dev.to\/t\/sql\" target=\"_blank\" rel=\"noopener\" rel=\"nofollow\">community such as Dev.to<\/a>. Or you could join an SQL-specific community and share your knowledge<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-to-learn-sql-free\">How to Learn SQL Free<\/h2>\n\n\n\n<p>If you want to <a href=\"https:\/\/careerkarma.com\/blog\/sql-contains\/\">learn SQL for free<\/a>, there are a variety of resources you can use. However, learning SQL for free may take additional effort on your part. As with learning any programming language, learning SQL will take some time and practice. Find out more about the steps you can take to learn SQL for free below.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-1-follow-interactive-tutorials\">Step 1: Follow Interactive Tutorials<\/h3>\n\n\n\n<p>One great way to learn SQL for free is to follow online tutorials that allow you to learn while also getting hands-on practice.

Thankfully, many of these organizations offer free tutorials on various subjects, including SQL.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-2-read-through-sql-community-threads\">Step 2: Read Through SQL Community Threads<\/h3>\n\n\n\n<p>Beginners can learn SQL online for free directly from experts. One way to do this is to join an online SQL community or chat room. These spaces allow beginners to ask questions and also follow along as experts discuss how they use SQL.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-3-take-an-online-class\">Step 3: Take an Online Class<\/h3>\n\n\n\n<p>Companies such as Udemy and Coursera host a variety of free online classes that learners can take advantage of. The great thing about learning SQL through a free online class is that you can do so at your own pace.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-step-4-join-a-free-bootcamp\">Step 4: Join a Free Bootcamp<\/h3>\n\n\n\n<p>Though many <a href=\"https:\/\/careerkarma.com\/subjects\/best-sql-bootcamps\/\">SQL bootcamp programs<\/a> come with steep tuition costs, there are also a variety of <a href=\"https:\/\/careerkarma.com\/blog\/best-free-coding-bootcamps\/\">free bootcamps<\/a> available.
