INITCAP() implementation returns char, with the first letter of each word in uppercase, all other letters in lowercase. Words are delimited by white space or characters that are not alphanumeric. The currentl implementation supports special characters in French, German, Spanish, and Turkish.
The return value is the same data type as char. The database sets the case of the initial characters based on the binary mapping defined for the underlying character set.
Examples
The following example capitalizes each word in the string:
SELECT INITCAP('hello world')
---------
Hello World
