Re: Query "stopped" in its tracks, still "running"

Who knows what really is going on under the covers? I expect that IBM's
got the DB2 (sorry, "Db2") engine tuned to a 'T'. It's just *really*
strange that it wrote 5M records to the new table and then, JUST STOPPED.

DASD's only at 41%.

Funny thing is, this particular query is actually the CTE portion of
another query that I broke out for this test.

Since it's EOD, I'm going to kill the job and resubmit it.

I don't know if SQL does something similar, but how's your disk space
looking??

If all else fails, try just the A-B join by itself; and the B-C by itself,
and see what you get...
