In my test case I was doing an INSERT query...
yet db_cassandra would complain there was no result... ( both the log
message and return code )
This is the reason I provided the patch.
after a little more testing I have found that I get this log message :
0(23827) ERROR: <core> [db_res.c:130]: db_free_result(): invalid parameter
So far in my testing everything has performed flawlessly, just with a few
less log lines :)
in essence this patch simply makes db_cassandra act the same when there is
no result set as it does when there are now rows.
( previously it would act like no result set was a big deal )

What would be the situation when the query is like
SELECT but there is no
result. Is the behaviour as expected with the new patch?
Anyone here using cassandra having comments? From my point of view is no
problem to push the patch, but I am not using cassandra, so cannot do a
proper review.
Cheers,

If doing a query that returns no results ( Insert etc )
db_cassa_raw_query would cause these ERRORS to be logged
0(22283) ERROR: db_cassandra [dbcassa_base.cpp:739]:
db_cassa_raw_query(): The resultype rows was not set, no point trying to
parse result.
0(22283) ERROR: avpops [avpops_db.c:333]: db_query_avp(): cannot do the
query
db_cassa_raw_query would also return -1 as a failure code which caused
avpops_db to log the query failure.
my patch changes the db_cassa_raw_query log message to debug level, and
returns success from the function.
I had a quick look to see if there was an elegant way to determine if we
should expect results, so we can vary the response code based on query
type, but I was unable to find anything other than doing string comparisons
on the query, so I opted to not bother with this as it would be erroneous.
Please find attached patch.
