User selects the Extract DDL option for an external table which generates a Create statement with NOPARALLEL and LOGGING clauses. Running the statement with the NOLOGGING clauses generates the following error as it is not allowed:
"ORA-30657: operation not supported on external organized table"
WORKAROUND:
Remove the NOLOGGING/LOGGING clause prior to executing the statement.
STATUS:
Waiting for fix to be released in a future version of SQL Navigator for Oracle.
