I have not tested this recently, but I believe it was true at 1 point in time on some version of Oracle. If the PK index is created at the same time as th PK constraint, then the index will be dropped when the constraint is disabled. However, if the UNIQUE index is created first & then the PK is created, when the constraint is disabled the UNIQUE index remains intact. HTH & YMMV!

Paul I had a question that if I was told by one user that they are loading some data into the DW table and disable the constraint but still getting the error about the unique Constraint. I tried to insert data into the Primary Key column and found that it is failing with Unique Constraint Error even the constraint is disabled. I tried to drop the constraint and tried to insert the data and found the same Unique constraint error which gives and idea the Primary Key related index is still not dropped even I dropped the Primary key constraint. I don't know if this is possible that If I drop the constraint using alter table drop constraint command and it is still not dropping the index. I hope this make more sense.

Your post is more likely to get a response if you show that you have tried on your own to solve your problem, and then ask a specific question rather than just announcing that you have a problem. *Paul Baumgartel* *CREDIT SUISSE* Information Technology DBA & Admin - NY, KIGA 1 One Madison Avenue New York, NY 10010 USA Phone 212.538.1143 paul.baumgartel@xxxxxxxxxxxxxxxxx www.credit-suisse.com ------------------------------ *From:* oracle-l-bounce@xxxxxxxxxxxxx [mailto: oracle-l-bounce@xxxxxxxxxxxxx] *On Behalf Of *Sanjay Mishra *Sent:* Tuesday, March 06, 2007 2:50 PM *To:* oracle-l@xxxxxxxxxxxxx *Subject:* Urgent-ORA0001 Unique COnstraint Hi I had to load some big data into the table and it has a composite Primary Key.
