Assume emp is a partitioned table with two partitions, m and z. Table emp is partitioned using the composite method. Partition m has subpartitions sp1 and sp2, and partition z has subpartitions sp3 and sp4. As the example shows, if you export the composite partition m, then all its subpartitions (sp1 and sp2) will be exported. If you export the table and specify a subpartition (sp4), then only the specified subpartition is exported.
Parameter File Method
> exp scott PARFILE=params.dat
The params.dat file contains the following:
TABLES=(emp:m,emp:sp4) ROWS=y
Command-Line Method
> exp scott TABLES=(emp:m, emp:sp4) ROWS=y
