I have a legacy table with no primary key, just a unique index with five columns. Also some of this unique index columns are nulable

I read that one solution is create a composite id with all columns, but when some column is nulable this solution fails

Other solution is create a new column for primary key, but i can't modify table schema

Which is the correct solution in this case??

Thanks
