# SQL Course Online (Self-Paced)

Canonical URL: <https://training-nyc.com/courses/sql-course-online>

## Overview

Turn the information in databases into useful insights by writing SQL queries. Once you understand the basics of viewing tables, columns, and rows, you’ll learn how to code queries to extract the specific information you want.

Learn how to filter the data, group it, and turn raw data into insights. Combine information from multiple tables using join statements. You’ll also learn more advanced techniques like aggregate functions, subqueries, and how to use functions with parameters.

In this hands-on course, you’ll learn PostgreSQL and the free DBeaver app to explore the database and execute SQL queries you write. The concepts you’ll learn on PostgreSQL can be applied to other flavors of SQL (such as Microsoft SQL Server, MySQL, etc.) with minor syntax differences.

#### Why Learn SQL?

With SQL, you can answer questions from information stored in a database (the ultimate system of storing data for most companies). As nearly every industry is becoming more data-driven, having this skill will give you a larger role in decision-making wherever you work.

SQL is vital to anyone in business or any job that involves working with data: business analysts, data analysts, data scientists, web developers, business people, and many others.
