I have three questions:
1. Is this "lost connection" behavior in the isql-v environment normal?
2. Does this "lost connection" message mean that the transaction has
rolled-back or is the command still running?
3. Is there a bette
the above, is that
the SPARQL query executed (partially) as isql-v stopped the transaction
because the "connection with the server had been lost" (or something like
that).
Thank you once more for your time.
