Re: Unique constraint and index-combination feature in 8.1

Are you saying you want to create a unique constraint across the indexes of 2 or more columns rather than across the columns themselves?

Hi,

Is it somehow possible to create a UNIQUE constraint that relies on non-unique
ONE-column indexes and uses index-combination feature in 8.1 ?

The alternative, which we use now, is to create a unique MULTI-column index on
the respective coulumns.

Thanks
