What is the behavior difference of using a non-unique
index to enforce a unique/primary key constraint when
inserting a duplicate value ?
Index range scan ?

I don't know. I made the non-unique index by mistake and noticed that the index did not drop when I was correcting the mistake.

Yes, Cherie, you can. When creating the primary key constraint

ahhh, mostly right. I found in v8.1.6 that if I use a non-unique index to enforce a unique/primary key constraint that the index does not drop when you drop the constraint.

Oracle will automatically create an index for your primary
key constraint.
I have a lot of large partitioned tables in my data warehouse.
All of my primary key indexes are non-partitioned. I would
like them to be partitioned.
When I drop the constraint and re-enable it, can I specify
at that
Hello, Cherie,
Short note first - when you drop primary key the associated index will be
dropped too.
To partition the index you will create this index first and then
alter table table name add constraint index name primary key(column
list);
