* Is there anyway to do this?

I have a table
Table "Users"
Column | Type | Modifiers
-----------+------------------------+-----------
userid | character varying(40) | not null
username | character varying(64) |
I want to get all the distinct first character of all usernames. And do
it in a way that is the most portable to MS SQL server.
Is there anyway?
Thanks

MSSQL Server does not recognize this syntax, but it does accept
select distinct substring(username, 1, 1)

Looking through the documentation on string functions would be helpful.
An example solution is:
select distinct substring(username from 1 for 1) from users;
