질문 # 298
View the Exhibits and examine PRODUCTSand SALES tables.
Exhibit 1

Exhibit 2

You issue the following query to display product name the number of times the product has been sold:

What happens when the above statement is executed?

A. The statement executes successfully and produces the required output.
B. The statement produces an error because ITEM_CNTcannot be displayed in the outer query.
C. The statement produces an error because a subquery in the FROMclause and outer-joins cannot be used together.
D. The statement produces an error because the GROUP BYclause cannot be used in a subquery in the FROMclause.

정답：A

질문 # 299
View the Exhibit and examine the structure of the CUSTOMERS table.

You want to generate a report showing the last names and credit limits of all customers whose last names start with A, B, or C, and credit limit is below 10,000.
Evaluate the following two queries:
SQL> SELECT cust_last_name, cust_credit_limit FROM customers
WHERE (UPPER(cust_last_name) LIKE 'A%' OR
UPPER (cust_last_name) LIKE 'B%' OR UPPER (cust_last_name) LIKE 'C%')
AND cust_credit_limit < 10000;
SQL>SELECT cust_last_name, cust_credit_limit FROM customers
WHERE UPPER (cust_last_name) BETWEEN 'A' AND 'C'
AND cust_credit_limit < 10000;
Which statement is true regarding the execution of the above queries?

A. Both execute successfully but do not give the required result
B. Only the second query gives the correct result
C. Only the first query gives the correct result
D. Both execute successfully and give the same result

정답：C

질문 # 300
You executed the following CREATE TABLE statement that resulted in an error:
SQL> CREATE TABLE employees(emp_id NUMBER(10) PRIMARY KEY, ename VARCHAR2(20), email NUMBER(3) UNIQUE, address VARCHAR2(500), phone VARCHAR2(20), resume LONG, hire_date DATE, remarks LONG, dept_id NUMBER(3) CONSTRAINT emp_dept_id_fk REFERENCES departments (dept_id), CONSTRAINT ename_nn NOY NULL(ename));
Identify two reasons for the error.

A. The FOREIGN KEY keyword is missing in the constraint definition
B. Only one LONG column can be used per table
C. The PRIMARY KEY constraint in the EMP_ID column must have a name and must be defined at the table level only
D. The NOT NULL constraint on the ENAME column must be defined as the column level
E. FOREIGN KEY defined on the DEPT_ID column must be at the table level only

정답：B,D

질문 # 301
Examine this SQL statement
DELETE FROM employees e
WHERE EXISTS
(SELECT' dummy'
FROM emp history
WHERE employee_ id= e. employee id);
Which two are true?

A. The DELETE statement executes successfully even if the subquery selects multiple rows.
B. The subquery is not a correlated subquery.
C. The subquery is executed before the DELETE statement is executed.
D. The subquery is executed for every row in the EMPLOYEES table.
E. All existing rows in the EMPLOYEES table are deleted,

정답：A,C

설명：
For the provided DELETE statement with an EXISTS clause:
* Option B: The subquery is executed before the DELETE statement is executed.
* Subqueries with EXISTS are typically executed before the outer DELETE statement to determine which rows of the outer query satisfy the condition.
* Option D: The DELETE statement executes successfully even if the subquery selects multiple rows.
* The EXISTS condition is used to check for the existence of rows returned by the subquery, regardless of how many rows there are. It returns TRUE if the subquery returns at least one row.
Options A, C, and E are incorrect because:
* Option A: This statement is incorrect; the subquery is indeed a correlated subquery because it references the employee_id from the outer query (employees).
* Option C: This is incorrect because not all existing rows in the EMPLOYEES table will be deleted, only those for which an associated record exists in the emp_history table.
* Option E: While technically the subquery may be evaluated multiple times, it is only executed for those rows in EMPLOYEES that satisfy the condition of the EXISTS clause.

질문 # 302
View the Exhibit and examine the data in EMP and DEPT tables.

In the DEPT table, DEPTNO is the PRIMARY KEY.
In the EMP table, EMPNO is the PRIMARY KEY and DEPTNO is the FOREIGN KEY referencing the DEPTNO column in the DEPT table.
What would be the outcome of the following statements executed in the given sequence?
DROP TABLE emp;
FLASHBACK TABLE emp TO BEFORE DROP;
INSERT INTO emp VALUES (2, 'SCOTT', 10);
INSERT INTO emp VALUES (3, 'KING', 55);

A. Both the INSERT statements would fail because the constraints are automatically retrieved when the table is flashed back.
B. Only the first INSERT statement would succeed because all constraints except the primary key constraint are automatically retrieved after a table is flashed back.
C. Only the SECOND INSERT statement would succeed because all the constraints except referential integrity constraints that reference other tables are retrieved automatically after the table is flashed back.
D. Both the INSERT statements would succeed because none of the constraints on the table are automatically retrieved when the table is flashed back.

정답：C
