Example: Remapping an array

The following example illustrates remapping an array from a field in main table format to a multi-row array table format. Typically, you would remap a field in main table array in order to improve your query performance. Using a multi-row array table array format allows the RDBMS to directly query the array rather than having to forward the query to Service Manager for evaluation.
