LCASE( )

This MySQL function converts a string given to all lowercase letters.

Syntax

Below is the syntax for this command. Text within square brackets (i.e, [ and ] ) are optional. Choices are separated by bars (i.e, | ). Ellipses preceded by a comma indicates a repeating pattern. Ellipses before or after syntax are used to highlight a relevant except from the larger syntax. Text displayed in italic letters represent text that should be replaced with the specific names related to the database (e.g., column with the name of the column).

LCASE(string)

Explanation

This function converts a string given to all lowercase letters. It's an alias of LOWER( ).

Examples

SELECT teacher_id,
CONCAT(LEFT(UCASE(name_last), 1),
SUBSTRING(LCASE(name_last), 2))
AS Teacher
FROM teachers;

In this example, we're using a combination of LEFT( ) paired with UCASE( ) and SUBSTRING( ) paired with LCASE( ) to ensure that the first letter of the teacher's name is displayed in uppercase and the rest of the name is in lowercase letters.
