A query is a way to ask a database for specific information. It allows users to retrieve, update, or delete data based on certain criteria.
For example, if you want to find all employees in a company with the job title 'Manager', you would use a query to get that information from the database.
Queries can be written in different languages, with SQL being one of the most common. Understanding how to write queries is essential for working with databases effectively.
Example
SELECT * FROM employees WHERE job_title = 'Manager';
