Re: Unique constraint and NULL values

   XPost: comp.databases.oracle.misc, comp.databases.oracle.server   
   From: REMOVE_BEFORE_REPLYING_dportas@acm.org   
      
   There is no documented method of making unique constraints ANSI-compliant in   
   MS SQL Server 7.0 or 2000. There are some workarounds but no supported   
   configuration parameter for changing the unique constraint behaviour.   
      
   I would be very surprised if there is such an undocumented feature but if   
   you know differently can you post an example or a reference?
