Partitioning is available
only when you create tables. User-defined format definitions for partitioning
variables are always transferred to the server, regardless of the
FORMATEXPORT= option.
Partitioning by a variable
that does not exist in the output table is an error. Partitioning
by a variable listed in the ORDERBY= option is also an error. Partition
keys are derived based on the formatted values in the order of the
variable names in the variable-list.
Be aware that the key
construction is not hierarchical. That is, PARTITION=(A B) specifies
that any unique combination of formatted values for variables A and
B defines a partition.
