Do you have practical experience creating SQL queries for working with databases?

Yes, I have practical experience in creating SQL queries for working with databases. For example, to select users with a specific status, you can use a query:

SELECT id, name, email FROM users WHERE status = 'active';

I also know how to write JOIN queries to combine data from multiple tables, use aggregate functions (SUM, COUNT), and create and optimize complex queries for testing and data analysis.
