Primary and foreign key constraints are not inherited. This is a defect in the current system. > What can I do to solve that problem ? Create an index table to provide a unique key for the whole hierarchy. Each member of the hierarchy has a foreign key reference to it na has its own primary key on the referencing field. Use triggers to update the index table. -- Oliver Elphick [EMAIL PROTECTED] Isle of Wight http://www.lfix.co.uk/oliver GPG: 1024D/A54310EA 92C8 39E7 280E 3631 3F0E 1EC0 5664 7A2F A543 10EA ======================================== "Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine."
