bookSQL And, Or, Not

Stryg for at vise menuen

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:


              
12

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

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


              
12

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

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


              
12

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