SQL Tutorial for Beginners: Learn How to Query Databases

In today’s data-driven world, almost every application, website, or business process involves data in some form. From your favorite e-commerce platform to your personal banking app, data is stored, managed, and retrieved using databases. To interact with these databases, we use a powerful language called SQL.

If you’re a beginner looking to learn how to query databases, you’re in the right place. This SQL tutorial will introduce you to the basics of SQL (Structured Query Language) and explain how you can use it to communicate with databases—no programming experience required.

What is SQL?

SQL stands for Structured Query Language. It’s the standard language used to store, retrieve, manage, and manipulate data in relational databases—databases that store data in tables, much like spreadsheets.

Think of a relational database as a collection of tables, where each table contains rows and columns. Each column has a specific type of data, like names, dates, or prices, and each row is a record (an entry) in the table.

Why Learn SQL?

SQL is one of the most in-demand skills for developers, data analysts, data scientists, and even marketers and business professionals. Here’s why learning SQL is a great idea:

Universal: It’s used by nearly every industry that deals with data.

Easy to Learn: SQL has a relatively simple and readable syntax.

Powerful: SQL allows you to ask complex questions and get exactly the data you need.

Great for Career Growth: SQL knowledge is a key skill in many tech and data-focused roles.

Core Concepts You Need to Know

Before jumping into actual queries, it’s helpful to understand some key concepts and terminology:

1. Tables

A table is a collection of data organized in rows and columns. For example, a Customers table might include columns like CustomerID, Name, Email, and Phone.

2. Rows

Each row in a table is a record. For example, one row in the Customers table could represent a single person.

3. Columns

Each column represents a specific attribute of the data. In our example, Email is a column that stores email addresses of customers.

4. Queries

A query is a question you ask the database. You use SQL to write queries and tell the database what information you want to retrieve.

Basic SQL Commands for Beginners

Here are the most commonly used SQL statements that beginners should become familiar with:

1. SELECT

The SELECT statement is used to read or retrieve data from a table. It’s the most commonly used SQL command.

Example (in simple English): "Show me all the data in the Customers table."

2. WHERE

The WHERE clause helps you filter results based on specific conditions.

Example: "Show me all customers whose country is Canada."

3. ORDER BY

You can sort the data using the ORDER BY clause.

Example: "Show customers sorted by their names in alphabetical order."

4. INSERT INTO

This command adds new records (rows) to a table.

Example: "Add a new customer named Alice with her email and phone number."

5. UPDATE

This modifies existing records in a table.

Example: "Change the phone number of customer with ID 10."

6. DELETE

This removes records from a table.

Example: "Delete the customer with ID 15."

A Real-Life Example: Online Store

Imagine you run an online store, and you have a table called Products. This table includes columns like ProductID, Name, Category, and Price.

With SQL, you could:

Find all products in the “Electronics” category.

List the top 5 most expensive products.

Update the price of a specific product.

Remove discontinued items.

SQL allows you to manage all of this with a few clear instructions.

How to Practice SQL

Learning SQL is best done by doing. Fortunately, there are many free and interactive tools you can use to practice writing SQL queries without needing to install anything:

Tpoint Tech (tpointtech.com/sql-tutorial)

W3Schools SQL Tutorial (w3schools.com/sql)

LeetCode SQL problems (great for more advanced practice)

Mode SQL Tutorial (mode.com/sql-tutorial)

These platforms let you write and test queries directly in your browser, often with real-world examples.

Final Thoughts

SQL is a foundational tool for anyone working with data. Whether you're a developer managing back-end systems, a data analyst exploring customer trends, or a marketer analyzing campaign results, knowing how to query databases will empower you to make smarter, data-driven decisions.

This beginner-friendly tutorial is just the first step. As you become more comfortable with SQL, you'll be able to write more complex queries, join multiple tables, and dive into advanced topics like subqueries and database design.

Does anyone believe that SQL certifications are still relevant?

Do employers actually care?

The inherent difficulties in trying to teach yourself SQL...

YouTube is not an educational platform. Yes, you can find dozens of "Learn SQL in an hour" type videos, but then what? There's no follow on, no support, no guidance.

(Most) paid courses are rubbish. They tend to be very cheap but you get what you pay for. Very few go into any proper depth, some are just printed articles albeit with some fancy diagrams. There's no support and no decent help. They take your money and you're f**ked if you have a question.

Certifications are a waste of time and money. I have been involved in maybe 100 candidate interviews and in NONE of those have I asked or been asked about certifications. Employers do not care.

Textbooks are hard work and most people give up. You can't ask a book a question. They're boring.

So what are YOU doing to learn SQL?
