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.

Example

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

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

SELECT LOWER('MÜNCHEN')

Returns: mÜnchen
