‍
If you wanted to convert the names in this table to lowercase, you would use the following query:

The LOWER() function is supported by most major databases, including MySQL, PostgreSQL, and SQL Server. However, the syntax may vary slightly depending on the database you are using. For more information, check out the documentation for your particular database.
