MySQL's LOWER(~) function converts string inputs to lowercase.
Syntax
SELECT LOWER("string1", "string2", ...);
SELECT LOWER(string_column1, string_column2, ...)FROM table;
Sample table - Students
student_id | fname | lname | day_enrolled | age | username |
|---|---|---|---|---|---|
1 | Sky | Towner | 2015-12-03 | 17 | stowner1 |
2 | Ben | Davis | 2016-04-20 | 19 | bdavis2 |
3 | Travis | Apple | 2018-08-14 | 18 | tapple3 |
4 | Arthur | David | 2016-04-01 | 16 | adavid4 |
5 | Benjamin | Town | 2014-01-01 | 17 | btown5 |
The above sample table can be created using the code here.
Examples
If we wanted to return fname in lowercase:
SELECT LOWER(fname)FROM students;
+--------------+| LOWER(fname) |+--------------+| sky || ben || travis || arthur || benjamin |+--------------+5 rows in set (0.00 sec)
We do not necessarily have to select from a table:
SELECT LOWER('HELLO');
+----------------+| LOWER('HELLO') |+----------------+| hello |+----------------+1 row in set (0.00 sec)
