To combine multiple conditions, use **AND**, **OR**, and **NOT** keywords, and also brackets **(**, **)** to set the priority.

For example, you want to select all songs' titles, that were produced between 1970 and 1990 years:

SELECT title FROM songs
WHERE year >= 1970 AND year <= 1990

Or you can select all records where singer is not Pink Floyd:

SELECT * FROM songs
WHERE NOT singer = 'Pink Floyd'

You can combine conditions for different columns, but not forget about brackets to define the priority:

SELECT * FROM songs
WHERE NOT (singer = 'Pink Floyd' AND price = 100)
