connections to the server are not supported. Therefore, when RESULTS=SERVER,
the entire query must be one that you can push to the server. If
not, this message appears in the log:
out of sync; you can't run this command now.
RESULTS=DISK lets you
run complex queries with result sets that would typically cause an
out-of-memory error. Result-set size is limited only to the free
space on the drive that is used for temporary files.
