SQL Bootcamp: Intensive Training for Beginners

---

Welcome to our SQL Bootcamp! Whether you’re an aspiring data analyst or someone who just simply interested in handling data, having SQL (Structured Query Language) know-how is absolutely beneficial.

What is SQL?

SQL is a special-purpose programming language designed for managing data in a relational database, and is used by a huge number of apps and organizations.

Why SQL?

With SQL, you can easily manipulate and query data stored in Relational Database Management System (RDBMS), or for stream processing in a Relational Data Stream Management System (RDSMS).

SQL Basics

Before we start our coding journey, let’s look at some essential SQL commands:

• SELECT: extracts data from a database
• UPDATE: updates data in a database
• DELETE: deletes data from a database
• INSERT INTO: inserts new data into a database
• CREATE DATABASE: creates new database
• ALTER DATABASE: modifies a database
• CREATE TABLE: creates new table
• ALTER TABLE: modifies a table
• DROP TABLE: deletes a table

Let’s Dive into Coding

Creating a Database

Firstly, let’s learn how to create a database using SQL:

Creating Tables

Next, we create a table in our newly made database:

Inserting Data

Now, we will insert some hypothetical data into our “Employees” table:

Selecting Data

Note our ‘John Doe’ record in the ‘Employees’ table? We want to select this data using the following command:

We hope this initial interaction with SQL has piqued your interest and demystified some of the complexities behind it. As with anything, practice and consistency is key. Keep practicing with these basic commands to cement your foundation, and stay tuned for our upcoming blogs about ‘Intermediate SQL Techniques’ and ‘Advanced SQL Practices’.

Happy Coding!
