SQL: with practice exercises, Learn SQL Fast

Easy to learn standard SQL commands such as "Select", "Insert", "Update", "Delete", "Create", and "Drop" can be used to accomplish almost everything that you need to do with a database. This SQL tutorial will provide you with the instruction on the basics of each of these commands as well as allow you to put them to practice using the SQL Interpreter.

Once you learn the basics, you'll be able to move on to more advanced topics. In the Standard SQL Functions course, you will learn how to utilize common SQL text and numeric functions, select and implement SQL date and time functions, and work with NULLs and advanced aggregate functions. You will get to practice your skills on 211 interactive exercises, which should take you about 18 hours.

If we add up the hours needed to do the above courses, we get 56 hours. That's all it takes to learn SQL. If you did everything without stopping, it would take two and a half days. Of course, no one can sit in front of the computer for that long! You have to sleep, eat, and do other things. So, plan your study schedule well.

Lastly, learning new things is a challenge. If SQL is something completely new to you, you need to systematize. It won't happen in a few hours, or even in a few days. Just like with learning to ride a bike, drive a car, or speak a new language, you need to practice.

Until I tried the courses, I had no idea that you could learn even faster by doing than just by watching. Using an interactive course, most of which is solving practical problems and applying queries, I felt as if I already had some knowledge. I was lucky to find LearnSQL right away. I didn't have to wander around YouTube looking for practical guides. (And it's so hard to find valuable learning content!) When I was doing the SQL from A to Z track, I quickly felt comfortable using SQL. That is why I recommend interactive courses.

Try to spend every spare moment learning SQL. Even fast results take time, and if you have some empty space in your daily agenda, you can fill it with other, non-interactive learning methods. If you have a 30-minute commute to work, you have extra time you can spend on learning SQL by listening to a SQL podcast .

Before learning the SQL syntax, it's important to have a model for what a relational database actually is. A relational database represents a collection of related (two-dimensional) tables. Each of the tables are similar to an Excel spreadsheet, with a fixed number of named columns (the attributes or properties of the table) and any number of rows of data.

Since most users will be learning SQL to interact with an existing database, the lessons begin by introducing you to the various parts of an SQL query. The later lessons will then show you how toalter a table (or schema) and create new tables from scratch.

One of the best platforms to learn coding skills is Codecademy. After you create an account, you can look for beginner courses such as Learn SQL. This course will teach you how to use SQL to communicate with relational databases:

If you own a WordPress website, your data will be stored in a MySQL database. When you learn the SQL query language, you can instruct WordPress on how to deal with this data. Plus, SQL skills can also help you get high-paying jobs in data science, marketing, and development.

One way to speed up the learning process is to take an online course or attend a training program that teaches SQL. These programs can provide a structured learning experience and guide individuals through the process of learning SQL. Many of these courses also include hands-on exercises and projects that can help individuals apply what they have learned and gain practical experience with the language.

Another way to learn SQL quickly is to practice regularly. This can involve working through tutorials or exercises, or even building small projects that utilize SQL. By regularly practicing and using the language, individuals can become more familiar with its syntax and commands, and can improve their proficiency over time.

Marketers, salespeople, and many other non-tech professionals must learn some amount of SQL to take operations to the next level. And with so many free resources out there, no one should make a big monetary investment to do so.
