What must you do to provide this functionality?

A. Set Close Allowed to Yes for both windows.

B. Set Hide on Exit to Yes for both windows.

C. Code a When-Window-Closed trigger for each window.

問題5

The Orders database table uses Order_id as its primary key. You have written the following code to use in the Orders block of a form:
SELECT orders_seq.NEXTVAL
INTO :orders.order_id
FROM SYS.dual;
Which statement is true about this code?

A. You should place this code in a Post_insert trigger to minimize the gaps in Order IDs.

B. If the named sequence does not exist, it is automatically created the first time the code is called.

C. You should place this code a in a database trigger to minimize the gaps in Order IDs.

D. If you place this Code in a trigger that fires when the record is inserted into the database, you will likely have more gaps in Order IDs than if you use the sequence as a default value for the item.

E. If you place this code in a trigger, you should ensure that Order_Id has its required property set to Yes.

F. You should place this code in Pre-insert trigger to minimize the gaps in Order IDs.

問題8

You put some code in a Post_Update trigger and raise the FORM_TRIGGER_FAILURE under certain conditions. Does a rollback take place if the trigger falls?

A. Yes. Although the update has been applied to the database, the old column values are retained as rollback data; so a failure of this trigger automatically reinstates the original values.

B. The value have already been applied, so you must programmatically save the old values in the global variables or PL/SQL variables if you want to reinstall the original values.

C. No. It is too late to perform a rollback at this stage because the update has already been applied.
