Can you write an SQL snippet to output data from a dataset?

To output data from a dataset in SQL, you typically use a SELECT statement. For example, if you have a table called employees and you want to retrieve all employees in the Sales department, you could write:

SELECT *

FROM employees

WHERE department = 'Sales';

This query selects all columns for rows where the department column equals 'Sales'. You can also project specific columns, apply ordering, or aggregate data. For instance:

SELECT employee_id, first_name, last_name

FROM employees

WHERE hire_date >= '2023-01-01'

ORDER BY last_name;

The result set will be displayed in the client or application that executed the query. In a production environment, you might add indexes on the filtering columns to improve performance.
