Hi,
I agree that the unique constraint on non-unique index is practicable
solution for the insert /*+ append */ scenario described above.
Are there some other problems, overheads etc. additional to the fact, that
the non-unique index allocates more space (additional ROWID in each index
entry) as the unique index with the same indexed columns?
thanks
