Getting the right username

Ok, thanks to all of you the update works fine. My last problem with this SP is that the store procedure does not accomondate for names that the same first intial and same last name. So for example say you have Sarah Parker and Scott Parker. When I use the SP there will be two sparker. Now in the SP the username that will be put in as a paramete will be sparker or saparker. How do I get it where the SP will look for a 2 character in the name if the previous name already exist? In the end every username HAS to be unique. Here is the query right now:

UPDATE dbo.Users
SET userstat = 'I'
FROM dbo.Users
INNER JOIN dbo.Contact ON dbo.Users.UserCntctID = dbo.Contact.CntctID
WHERE dbo.Users.UserStat = 'A' AND dbo.Users.UserDBMnkr NOT IN ('sysuser', 'RAMQ', 'RAMQ2')
AND LOWER(LEFT(dbo.Contact.CntctFrstNme, 1) + dbo.Contact.CntctLstNme) = 'gmahoney'

For the initial assignment, i.e. INSERT, of the new id, you could check for the existence of *every* possible valid combination and pick the *shortest* one.  I can provide code for that if you like.

But when doing a lookup / update, you will have to pass in the specific userid and/or the full name (full name will always work unless you have two, say, John Smith's working there).

The computer by itself can't know from userid "sparker" alone whether that relates to Sarah or Scott.

What if you  have "Sarah Parker" and "Sam Parker"?

I didn't think about that senario. So I guess I just need a better solution overall to doing this? Any ideas?

Ok, well right now and need a solution for lookup and update. Changing how data is inserted is not possible right now. What if I do something like this. Is there anyway to run some type of conditional statements (which I doubt in sql) that will allow me to say "if duplicate names exist find a unique letter to make the name unique" Usually things like this are done with CF or other languages but maybe there is something with sql that I don't know!! If not then I guess this not possible with the current setup of my system.
