Hi there,
How are new usernames actually checked? It might lead to irritations when you allow

Hi Frank,
I feel usernames should not be case-sensitive...
Not a solution, just my opinion

ok...was thinking of a solution to this on my way back to home yesterday...
how abut this...
have 2 fields that will store the total of ASCII values of small alphabetes and capital.
username LowerASCII UpperASCII
frank 530 0
jonathan 855 0
sachin 630 0
Frank 428 70
Jonathan 749 74
Sachin 515 83
franK 423 75
FranK 321 145
FrAnK 224 210
now the filter condition will be
username = ? AND smallASCII = ? AND bigASCII = ?
to say,
username = 'FrAnK' AND smallASCII = 224 AND bigASCII = 210
Not sure if the combinations will lead to any duplicate totals!!!
Hope this is of some help...

I dont think Im doing any checking. That good or bad? We use email address as the login id (though there is really an ident on the row that is the true key for those who care). Is having two Franks bad? I could enforce no duplicate names easily enough if that is good enough...?

No problem with me, as long as all post are of formal and textual quality.

Aha! So the user name (login name, screen name, full name; whatever you decide to call it) is no longer a unique identifier. It's now just a free field (Full Name in the profile form) and the email (no longer exposed in one's profile) has replaced it as the natural primary key. So I can change my Full Name to anything I like ("Frank Kalis", "Andy Warren", etc.) and that will be the tag on all my posts...
I don't think this is a good idea. Perhaps one's email (as the natural primary key) should instead be the tag on one's posts, or, if that is felt to expose too much, then one's "screen name" should be a new column that is checked as unique (and case insensitive) and not modifiable.

Perhaps. I agree we dont want 100k Franks running around - 50k maybe, but 100k would be too many. Will look at it when I can.

To much luxury is not good
Maybe this will help :
create table T_SQLServerCentralUsers(uidnr int identity(1,1) primary key,
uAlias varchar(128) COLLATE SQL_Latin1_General_CP1_CS_AS not null,
uDtMember datetime not null default getdate()

from T_SQLServerCentralUsers sT
) S
on T.uidnr = S.uidnr

then
Send a notification to the altered aliasses email-adres with justification that the oldest member kept the name and ony sequence number is added
Alter table T_SQLServerCentralUsers
drop constraint U_uAlias

-- edit post -- is not working ??
also add this at the bottom of the script :
insert into T_SQLServerCentralUsers (uAlias) values('jonathaN')
results in :
Server: Msg 2627, Level 14, State 2, Line 1
Violation of UNIQUE KEY constraint 'U_uAlias'. Cannot insert duplicate key in object 'T_SQLServerCentralUsers'.
The statement has been terminated.
