   It seems that you have already resolved the problem, so I am not   
   digging into it. But a comment on the script:   
      
   > create table Subaccounts   
   >  (   
   >  SAUK nvarchar(4) unique,     -- arbitrary length   
   >  SAOrd int,   
   >  SAName nvarchar(40),     -- arbitrary length   
   >  SAInACUK nvarchar(4),     -- arbitrary length   
   >  foreign key (SAInACUK) references Accounts(ACUK)   
   >  )   
      
      
   I recommend that you always include an explicit NULL/NOT NULL definition.
