PostgreSQL- LOWER function

  • Last Updated : 08 Oct, 2021

Syntax: LOWER(string or value or expression)

  • The LOWER function takes in value with either all uppercase or partial uppercase values or characters and convert them into lower case of the same type.
  • If the supplied argument is string-convertible, one can make use of the CAST function which converts a non-string value to a string.

SELECT LOWER(title) from film;


Example 2:

The below statement converts an upper case string to lower case:
