i read the follwing line in oracle 9i documentation,

Unique and primary keys can use non-unique as well as unique indexes. They can even use just the first few columns of non-unique indexes.

i am planning to use a primary key constraint enforced by the first few columns of a non-unique index.any feedback or advice or gotchas in having such a setup.

thanks
sai
