David,

Now I'm really puzzled. My question back to the OP was to suggest to him that you can't have a PK without and index (backed up by the Concepts Manual stateing "Oracle enforces all PRIMARY KEY constraints using indexes.") But after taking me to task on that, you respond back to the OP that what he wants is impossible -- exactly what I was trying to get the OP to think through and discover for himself. What am I missing? Received on Mon Jun 25 2007 - 20:33:50 CDT
