Monitoring Nested Tables   

Another table type new to Oracle8 was the nested table, defined as a table called by reference in another table and whose reference value appears as a column. Refer back to the table columns report, shown in Listing 10.7_, and note the columns named “xxxx_list”(my self-imposed naming convention): each is an example of a nested table reference column. I suggest that for ease in recognizing a nested table column, you impose a similar convention. Each of these “xxxx_list” columns contains a pointer value that points to a nested table. The DBA_NESTED_TABLES view provides a convenient place to monitor nested tables. An example of a report run against the DBA_ NESTED_TABLES view is shown in Source 10.18. 

SOURCE 10.18 Example of script to monitor nested tables.
