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.

If 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 messages. 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
