INITCAP function usage in Netezza

In Netezza, with in a string every first letter after space will be turned into an upper case and remaining letters will be into lowercase.
In Orcale, it'll converts the very first letter after space or any special symbol into uppercase and remaining letters into lower case.
In Teradata , we don't have this function.
