WHERE customer_id IN
(SELECT customer_id FROM customers
WHERE cust_last_name = 'Roberts' AND credit_limit = 600); Which statement is true regarding the execution?

It would not execute because a subquery cannot be used in the WHERE clause of an UPDATE statement.

The table prefix is missing for the column names in the SELECT clause.

The NATURAL JOIN clause is missing the USING clause.

The DEPARTMENTS table is not used before the EMPLOYEES table in the FROM clause.

The EMPLOYEES and DEPARTMENTS tables have more than one column with the same column name and data type.

Examine the SQL statement:
SQL > SELECT city, last_name LNAME FROM MEMBERS ORDER BY 1, LNAME DESC;
What would be the result execution?

It displays all cities in descending order, within which the last names are further sorted in descending order.

It fails because a column alias cannot be used in the ORDER BY clause.

Question 24

View the Exhibit and examine the details of the PRODUCT_INFORMATION table.
1Z0-071 dumps exhibit

You have the requirement to display PRODUCT_NAME and LIST_PRICE from the table where the CATEGORYJD column has values 12 or 13, and the SUPPLIER_ID column has the value 102088. You executed the following SQL statement:
SELECT product_name, list_price FROM product_information
WHERE (category_id = 12 AND category_id = 13) AND supplier_id = 102088; Which statement is true regarding the execution of the query?

It would not execute because the entire WHERE clause is not enclosed within parentheses.

It would execute but would return no rows.

It would not execute because the same column has been used twice with the AND logical operator.

It would execute and return the desired.

Question 25

Evaluate the following SELECT statement and view the exhibit to examine its output:
SELECT constraint_name, constraint_type, search_condition, r_constraint_name, delete_rule, status, FROM user_constraints

CON SEARCH_CONDITION R_CONSTRAINT_NAME DELETE_RULE
STATUS ORDER_DATE_NN C
"ORDER_DATE" IS NOT NULL ENABLED ORDER_CUSTOMER_ID_NN C
