SQL is a fairly simple language that is used to build queries against databases such as MySQL, Oracle, Microsoft SQL Server, PostgreSQL, and others. After studying it, you will be able to easily perform various operations in the database, including fetching data, creating tables, inserting, updating and deleting data from tables, creating indexes, managing access rights, and others.

But where can you practice SQL syntax if you don't have a database handy? To do this, just install the SQL Play mobile application, which is also available as a web version. It already has a small database with a dozen tables and a set of test data.

Thus, immediately after installing the application, you have your database where you can practice your skills in SQL. To achieve this, just enter the desired request in the input field and execute it. And below is the result of the execution.

Unfortunately, unlike real database clients, SQL Play does not have syntax highlighting or prompting when typing commands. But if you make a mistake, the application will tell you where it is hidden. Or you can use the command search to find the one you need.

Learning SQL can be beneficial in a variety of ways, including:

  • Working with data. SQL allows you to efficiently work with data, including retrieving, modifying, deleting, and adding data. Because of this, SQL is used in various fields, including business intelligence, scientific research, marketing analysis, and others.
