nls_lower::=
NLS_LOWER returns char, with all letters lowercase.
Both char and 'nlsparam' can be any of the datatypes CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB. The string returned is of VARCHAR2 datatype and 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.
The following statement returns the character string 'citta'' using the XGerman linguistic sort sequence:
SELECT NLS_LOWER ('CITTA''', 'NLS_SORT = XGerman') "Lowercase" FROM DUAL; Lowerc ------ citta'
