SQL Between

If you need to choose records with the value in some range, you can use BETWEEN command:


              12
            
SELECT id FROM songs
WHERE year BETWEEN 1970 AND 1990

The result of this query is equal to:


              12
            
SELECT id FROM songs
WHERE year >= 1970 AND year <= 1990

Note that it includes boundary values. You can use BETWEEN with NOT operator: С NOT BETWEEN A AND B, which is equal to С<A OR С>B.

SQL BETWEEN for strings

If you apply BETWEEN to string values, you'll get all records from the table between these fields. Test the next example


              12
            
SELECT title FROM songs
WHERE album BETWEEN 'Highway to Hell' AND 'If You Can Believe Your Eyes and Ears'
