Have you had experience writing SQL queries for working with databases?

Yes, experience in writing SQL queries for working with databases typically includes creating queries for data retrieval (SELECT), insertion (INSERT), updating (UPDATE), and deletion (DELETE). For example, to select all users from the 'users' table with a certain condition, you can write:

SELECT * FROM users WHERE status = 'active';

It is also important to know how to use JOINs to combine data from multiple tables, as well as aggregate functions (SUM, COUNT, AVG) for data analysis.
