When importing data into a table using the "Import Table Data" from menu Database | Import, Toad crashes/closes if there is an error in the flat file data e.g. a value is blank for a non-null field. Toad 11.6 would prompt with an error and ask if user wants to Ignore/Cancel the import request. No prompt is appearing in Toad 12.
対策
WORKAROUND
Use Toad 11.6 for the import
STATUS
Waiting for fix in a future release of Toad for Oracle
