This project contains a number of SQL exercises that can be used to practice SQL skills. The exercises are divided into three levels: beginner, intermediate, and advanced.
To run the exercises, you will need to have a copy of SQL Server or MySQL installed on your computer. You can also use a cloud-based SQL database, such as Microsoft Azure SQL Database or Amazon RDS MySQL.
Once you have a SQL database, you can connect to it using a SQL client, such as Microsoft SQL Server Management Studio or MySQL Workbench.
To run an exercise, simply open the SQL script file in your SQL client and execute the queries.
The beginner exercises are designed to introduce you to the basics of SQL. They cover topics such as creating tables, inserting data, querying data, and updating data.
The intermediate exercises are designed to challenge your SQL skills. They cover topics such as joins, subqueries, and aggregation functions.
The advanced exercises are designed to test your mastery of SQL. They cover topics such as window functions, triggers, and stored procedures.
- Start with the beginner exercises. The beginner exercises are a great way to learn the basics of SQL.
- Don't be afraid to ask for help. If you get stuck on an exercise, you can always ask for help from a friend, colleague, or online forum.
- Have fun! SQL can be a challenging but rewarding language to learn.
