this PR attempts to fix issue #1119
Currently the rows count is only set to 0 in the
CommandComplete
handler, but in case of an error this handler isn't called.I changed the rows reset to be also on the query prepare handler which is called any time a query starts execution. This is in the same place where other variables are cleared (e.g. the result).
I also added a new test that checks this scenario (fails before the fix and passes once fix is applied)
