RE: unique constraint violation problem

Tue, 08 Jul 2003 06:16:00 -0700

Thanks for all of you who replied the message. I apologize for not explaining the problem clearer. Actually, the error was reported at 13:35:13pm from the application. There is a column called date_created in the table that records what time the record was created. The value of date_created for the record that caused error message is the same as reported from application. That's why I said that the record was inserted into the table successfully.

I know Oracle recommends that we do not explicitly define unique indexes on tables. Why?

My explanation would be that the record was NOT inserted successfully into the table. Proof of that would be that there are no duplicate records in the table.
