You can use the show option to see the contents of the export dump file. Then make sure all objects are dropped.

I am 100% positive . I tried this process 2-3 times using different approach but same output. I tried to create objects first using no data. I also tried to create objects as part of loading data but no difference. I enabled 10046 trace for the import process but that also didnt help, it showing err=1 at several places but I couldnt figure out why.

Avnish,

Are you absolutely sure that the target table is either gone before the
import, or empty? You should not be getting a unique constraint violation
if the table does not exists before import.

The step that Oracle import follows for importing is:
Create the table
import the data
create constraints
create triggers
apply grants.

I! f you are getting a unique constraint violation during import, then the
constraints exist before the table is being imported which leads me to
believe everthing is not as clean as you think. Either that, or the uniqe
constraint in the source database has been disabled, and you have bad data.

Make sure you drop the target table before you start the import. And look
at the source data table's constraints to make sure they are all enabled.

Good Luck!

I am trying to export a table from one database to another. Table in target
database is dropped before importing and is being created as part of import
process. During import process data Oracle is complaining Unique constraint
violated and throwing out following mes! sages. Its complaining on index
abhset1 which is on columns [asset, book, yr_end_date]. I tried to compare
data in source and target. Somehow yr_end_date for year 2003 is changing to
2002 while importing data. Table doesnt have any triggers. Indexes in both
source and target are same. Table definition is exactly same and created
during import. Tried to export 2-3 times but same result. Anybody ran into
this issue before. How should I approach to troubleshoot. Thanks
