Here are a few tips to help you get started with learning SQL:
Install a database management system (DBMS): MySQL, PostgreSQL, or MS SQL on your computer.
If you don't have an existing dataset, download a sample database, such as the Wide Word Importers database.
Install a SQL IDE to query the database.
Start with simple queries. Learn how to use SELECT statements to retrieve data from a table.
Practice using different clauses, such as WHERE, GROUP BY, and JOIN.
Experiment with creating tables, views, and stored procedures to understand the different components of a database.
