NLS_LOWER

SQLRF51554Syntax

SQLRF51555Purpose

NLS_LOWER returns char, with all letters lowercase.

Both char and 'nlsparam' can be any of the data types CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB. The string returned is of VARCHAR2 data type if char is a character data type and a LOB if char is a LOB data type. The return string is in the same character set as char.

The 'nlsparam' can have the same form and serve the same purpose as in the NLS_INITCAP function.
