Question

A table has been partitioned using the RANGE_N function and includes the NO RANGE and UNKNOWN partitions. There are gaps in the ranges and the designer needs to add new partitions to fill the gaps. The data in the NO RANGE partitions must be checked against the new partitions. Which procedure should be used?

Answer
    • Create another table with the new partition definition, then submit an INSERT SELECT statement to populate the new table.

    • Create another table with the new partition definition, then extract the data from the NO RANGE and UNKNOWN partitions and import the data into the new table.

    • Submit an ALTER TABLE statement to add the new partitions, extract the data from the NO RANGE and UNKNOWN partitions, and import the data into the existing table.
