when using the Toad Import Wizard to map to existing table I get the error “The current transaction has been rolled back because of a deadlock or timeout. Reason code 68.”. The occurs after I select the existing table to map to after about 30 seconds (field mapping options are not displayed). I’m trying to import ~24K records in .csv format. When I map these records to a new table no error results.
What connection are you using? Can you show us a screenshot?
