what is wrong with this sql? It does not allow me to insert a test computer, when test is not in database

if not exists (select distinct NetBIOSName from Computers)
begin
insert into Computers(NetBIOSName, IP)
values('test','111.22.33.444')
end

Unless your table is empty, select distinct NetBIOSName from Computers will always return at least one record.


[Edit]
NM you found it.
