In Toad 10.5.1.3, I'm trying to do a 'Copy Data to Another Schema' by right clicking on a set of source tables in the Schema Browser. In this set of source tables if one of the tables in the middle is empty, Toad will throw the following error …
WORKAROUND:
Break up your data copy for your table set before an after any empty tables.
STATUS:
Waiting for fix in a future release of Toad for Oracle
