Oracle Database Discussions

Hi,
i'm tring to export data with sqldeveloper but it fail with:

"No valid columns available for exports, we do not currently support clob or blob columns"

No clob/blob column in table and no dblink in query:


select carcc, carnr, carpr, carre, carnu
from my_tab_ph
where....

can depends on some configuration parameter of my developer?

Thank you.
