Getting Directed Queries
You can obtain catalog information about directed queries in two ways:
Run GET DIRECTED QUERY
GET DIRECTED QUERY queries the system table V_CATALOG.DIRECTED_QUERIES on the specified input query. It returns details of all directed queries that map to the input query.
The following GET DIRECTED QUERY statement returns two directed queries that map to the same input query, findBostonCashiers_OPT and findBostonCashiers_CUSTOM:
=> GET DIRECTED QUERY SELECT employee_first_name, employee_last_name
FROM employee_dimension WHERE employee_city='Boston' AND job_title='Cashier';
-[ RECORD 1 ]---+

FROM public.employee_dimension AS employee_dimension/*+projs('public.employee_dimension')*/
WHERE (employee_dimension.employee_city = 'Boston'::varchar(6)) AND (employee_dimension.job_title = 'Cashier'::varchar(7))

annotated_query | SELECT employee_dimension.employee_first_name, employee_dimension.employee_last_name FROM public.employee_dimension/*+Projs('public.Emp_Dimension_Unseg')*/ WHERE ((employee_dimension.employee_city = 'Boston'::varchar(6)) AND (employee_dimension.job_title = 'Cashier'::varchar(7)))
Query V_CATALOG.DIRECTED_QUERIES
You can query the system table V_CATALOG.DIRECTED_QUERIES directly. For example:
=> SELECT query_name, is_active FROM V_CATALOG.DIRECTED_QUERIES WHERE query_name ILIKE '%findBostonCashiers%';
query_name | is_active
---------------------------+-----------
findBostonCashiers_CUSTOM | t
findBostonCashiers_OPT | f
(2 rows)
(2 rows)
Query results for the fields INPUT_QUERY and INPUT_QUERY are truncated after ~32K characters. You can get the full content of both fields in two ways:
- Use the statement
GET DIRECTED QUERY. - Use
EXPORT_CATALOGto export directed queries.
