LOWER()

Available in: DSQL, ESQL, PSQL

Added in: 2.0

Description: Returns the lower-case equivalent of the input string. This function also correctly lowercases non-ASCII characters, even if the default (binary) collation is used. The character set must be appropriate though: with ASCII or NONE for instance, only ASCII characters are lowercased; with OCTETS, the entire string is returned unchanged.

Result type: (VAR)CHAR

Syntax:

LOWER (str)

Example:

select Sheriff from Towns
  where lower(Name) = 'cooper''s valley'
