Subj:   Re: Multiset with a UPI
From:   John_Wight

A Multiset table with a unique constraint (i.e. UPI or USI) will be the same as a SET table with a unique constraint - i.e. No duplicate row check. If you have a Multiset table, why would you apply a unique constraint? Maybe there is a good reason but (to date) I have not identified any - but would be humbled to know if there was!!!

For what it's worth on today's market!
