NLS_INITCAP() Function in Oracle
In Oracle, the NLS_INITCAP() function returns its argument with the first letter of each word in uppercase, and all other letters in lowercase.
However, the actual capitalisation will depend on the collation being used. For example, it could result in more than the first letter being capitalised.
It’s similar to the INITCAP() function, except that it accepts a second argument that allows you to specify the collation. The collation handles special linguistic requirements for case conversions.
