You can use it to create tables, run queries, define relationships between tables, and organize data in your database. In this article, we’ll explore what it is and how it works. We’ll also see some examples of SQL code so you can get familiar with the language. Keep reading to learn more about this important topic for website owners!

What is SQL?

SQL stands for Structured Query Language. It’s a programming language that’s been used since the 1970s and is still widely used today. It has many uses, from creating tables to running queries to organizing data in your database. In this article, we’ll explore how it works and some examples of SQL code!

How does SQL work?

The programming language designed to extract data from a database. The language is composed of four basic operations: SELECT, INSERT, UPDATE, and DELETE.

SELECT lets you pull data from the database. For example, you could use a SELECT operation to get a list of all clients at a company.

INSERT lets you add new data to the database.

UPDATE allows you to change the values in an existing row in the database. This can be useful if, for example, you need to update someone’s phone number or email address on record with your business.

DELETE lets you remove rows from your database table entirely. You can think of it as “erasing” information from your table.

Why is it important for your website?

SQL is an important language for web developers because it lets them interact with databases.

It’s also important for website owners to know about SQL for two reasons: You can use it to get information from your database and you can use it to create tables and organize data in your database.

Without the use of SQL, you would not be able to utilize websites how you do day today.

Who uses SQL?

SQL is a crucial, structured, and object-oriented programming language. It is used by developers who need to manipulate data for websites. Developers use it to create tables, run queries, define relationships between tables, and organize data in your database.

A programmer that specializes in SQL is called a “DBA” or “database administrator.” The DBA is responsible for all the actions related to building and managing databases. The DBA is also responsible for the security of your information.

You’ll also often see SQL features in other languages like Python or PHP which I have spoken about previously in another blog article.


SQL is one of the most important skills for anyone in web development. There are many different ways to use SQL, and this article has given you some examples to get you started.

In summary, you can use SQL to extract data from your database, manipulate it in various ways, and use it again in reports or other analyses. SQL is an essential tool for anyone working in website design or development and the majority of websites would not be possible without the use of SQL.
