SQL is a powerful and widely used language for querying and manipulating data in relational databases. However, learning SQL can be challenging, especially if you are new to programming or database concepts.
That’s why I have created these SQL short notes handwritten in PDF format, which cover the most important topics and concepts of SQL in a concise and easy-to-understand way.
Overview of the Notes
These notes are based on my personal experience and knowledge of SQL, as well as the official documentation and online resources. They are not meant to be a comprehensive guide or a substitute for a textbook, but rather a quick reference and a revision tool for anyone who wants to learn or review SQL.
The notes are divided into 10 sections, each focusing on a different aspect of SQL, such as data types, operators, functions, clauses, joins, subqueries, etc. Each section contains a brief introduction, a list of key points, and some examples of SQL queries and their outputs. The notes are written in a clear and simple language, with diagrams and tables to illustrate the concepts.
The notes are in PDF format, which means you can easily download, print, or view them on any device. The notes are also handwritten, which gives them a personal touch and makes them more engaging and memorable.
