You work as a DBA for a company and as a performance improvement measure, you implemented the result cache in your database. View the Exhibit named SETTING and note the result cache settings. Many users in the company state that performance has improved on the queries they use but some users complain that they have not got any performance benefit on the queries they use. You checked all the queries they use and the following is one of them:

SQL> SELECT slnoq.currval as "SLNO", prod_id, pdname, 2 cust_name FROM sales WHERE sl_date < sysdate; View the Exhibit named TEST and examine the testing performed to check this. Why is the result cache not used? (Choose all that apply.)
