Oracle Database SQL Sample Questions (Q270-Q275):

NEW QUESTION # 270
The ORDERS table has a primary key constraint on the ORDER_ID column.
The ORDER_ITEMS table has a foreign key constraint on the ORDER_ID column, referencing the primary key of the ORDERS table.
The constraint is defined with on DELETE CASCADE.
There are rows in the ORDERS table with an ORDER_TOTAL less than 1000.
Which three DELETE statements execute successfully?

  • A. DELETE FROM orders;
  • B. DELETE * FROM orders WHERE order_total<1000;
  • C. DELETE FROM orders WHERE order_total<1000;
  • D. DELETE order_id FROM orders WHERE order_total<1000;
  • E. DELETE orders WHERE order_total<1000;

Answer: A,C,E

Explanation:
In Oracle 12c SQL, the DELETE statement is used to remove rows from a table based on a condition. Given the constraints and the information provided, let's evaluate the options:
* A. DELETE FROM orders WHERE order_total<1000;: This statement is correctly formatted and will delete rows from the ORDERS table where ORDER_TOTAL is less than 1000. If there is a DELETE CASCADE constraint, corresponding rows in the ORDER_ITEMS table will also be deleted.
* B. DELETE * FROM orders WHERE order_total<1000;: This syntax is incorrect. The asterisk (*) is not used in the DELETE statement.
* C. DELETE orders WHERE order_total<1000;: This statement is also correctly formatted and is a shorthand version of the DELETE statement without the FROM clause.
* D. DELETE FROM orders;: This statement will delete all rows from the ORDERS table, and with DELETE CASCADE, it will also delete all related rows in the ORDER_ITEMS table.
* E. DELETE order_id FROM orders WHERE order_total<1000;: This syntax is incorrect because you cannot specify a column after the DELETE keyword.

WHEN MATCHED THEN
UPDATE SET o.order_total = m.order_total
DELETE WHERE (m.order_total IS NULL)
WHEN NOT MATCHED THEN
INSERT VALUES (m.order_id, m.order_total);
What would be the outcome of the above statement?

  • A. The ORDERS_MASTER table would contain the ORDER_IDs 1, 2, 3 and 4.
  • B. The ORDERS_MASTER table would contain the ORDER_IDs 1, 2 and 3.
