LOWER

Converts the input string to lowercase characters. Note that Firebolt uses the POSIX locale, therefore lower only converts the ASCII characters “A” through “Z” to lowercase. Non-ASCII characters remain unchanged.

Syntax

LOWER(<expression>)

Parameters

Parameter	Description	Supported input types
`<expression>`	The string to be converted to lowercase characters.	`TEXT`

Return Type

TEXT

Example

The following example converts a game player’s username from uppercase to lowercase characters:

SELECT
	LOWER('ESIMPSON') as username

Returns: esimpson

Because Firebolt uses the POSIX locale, non-ASCII characters are not lowercased:

SELECT LOWER('MÜNCHEN')

Returns: mÜnchen
