    IS BEGIN
    DELETE FROM PLAYER
    WHERE ID = V_ID

    WHEN STATS_EXITS_EXCEPTION THEN
    DBMS_OUTPUT.PUT_LINE(Cannotdeletethisplayer, childrecordsexistin PLAYER_BAT_STAT table);

    2. Under which two circumstances do you design database triggers? (Choose two)

    A. To duplicate the functionality of other triggers.

    A was modified and recompiled at 9 A.M. Remote procedure B was later modified and
    recompiled at 11 A.M. The dependency mode is set to TI MESTAMP. What happens when
    procedure A is invoked at 1 P.M?

    A. There is no affect on procedure A and it runs successfully.

    4. What is a condition predicate in a DML trigger?

    A. A conditional predicate allows you to specify a WHEN-LOGGING-ON condition in the trigger body.
    B. A conditional predicate means you use the NEW and OLD qualifiers in the trigger body as a condition.
    C. A conditional predicate allows you to combine several DML triggering events into one in the trigger body.
    D. A conditional predicate allows you to specify a SHUTDOWN or STARTUP condition in the trigger body.

    5. This statement fails when executed:

    CREATE OR REPLACE TRIGGER CALC_TEAM_AVG

    D. ALTER TABLE employees DISABLE ALL TRIGGERS;

    8. You have a row level BEFORE UPDATE trigger on the EMP table. This trigger contains a SELECT statement on the EMP table to ensure that the new salary value falls within the minimum and maximum salary for a given job title. What happens when you try to update a salary value in the EMP table?
