Is there anyway to do this?

From

Date:
I have a table 
              Table "Users" Column   |          Type          | Modifiers 
-----------+------------------------+-----------userid    | character varying(40)  | not nullusername  | 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

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

MSSQL Server does not recognize this syntax, but it does accept

select distinct substring(username, 1, 1)
