Hi,
fine with me. I just need to distinguish between the "no rows" and "any
other error" cases.
Torque throws "TorqueException" for everything. Now try to do
constructive error handling here... =:-( I ended up very much with
try
{
... anything ...
}
catch(TorqueException te)
{
log.error("Torque failed" ,te);
System.exit(1); // :-)
}
when working outside Turbine...
Regards
Henning
