Anna,
A unique constraint is a unique index and vice-versa which will explain your
error message. Also, no there will be no duplicate records because you defined the
index as unique. I would doubt your statement about the record being inserted
although the application may have updated the other fields in the record in response
to the error. Depends on who wrote the application and what they did for error
handling.

Hi,
I created a unique index on a table called REGISTRATION_K, but no unique
constraint. Last week when the application tried to insert a record into
the table, we got following error in the log file:
Oracle::st execute failed: ORA-00001: unique constraint (REGISTRATION_K)
violated
However, the record was inserted into the table successfully. There are no
duplicate records in the table. Could anyone explain why?
Any input will be highly appreciated. Thanks in advance.
Anna
