질문 # 105
View the exhibit and examine the description of the DEPARTMENTS and EMPLOYEES tables.

You wrote this SQL statement to retrieve EMPLOYEE_ID, FIRST_NAME, and DEPARTMENT NAME, for all employees:
SELECT employee_id, first_name, department_name
FROM employees
NATURAL JOIN departments;
The desired output is not obtained after executing the above SQL statement. What could be the reason for this?

A. The table prefix is missing for the column names in the SELECT clause.
B. The NATURAL JOIN clause is missing the USING clause.
C. The DEPARTMENTS table is not used before the EMPLOYEES table in the FROM clause.
D. The EMPLOYEES and DEPARTMENTS tables have more than one column with the same column name and data type.

정답：D

설명：
Natural join needs only one column to be the same in each table. The EMPLOYEES and DEPARTMENTS tables have two columns that are the same (Department_ID and Manager_ID)

질문 # 106

CREATE TABLE alter_test (c1 VARCHAR2 (10) , c2 NUMBER (10);
INSERT INTO alter-test VALUES ('123', 123);

Which is true about modifying the columns in ALTER_TEST?

A. c1 can be changed to varchar2 (5) and c2 can be changed to number (13, 2) .
B. c1 can be changed to number (10) and c2 can he changed to vahchar2 (10) .

D. c2 can be changed to number (10) but c2 cannot be changed to varchab2 (10) .
E. c2 can be changed to varchar2 (10) but el cannot be changed to number (10).

질문 # 107
Which two are true about the NVL, NVL2, and COALESCE functions?

A. NVL must have expressions of the same data type.
B. The first expression in NVL2 is never returned.
C. NVL2 can have any number of expressions in the list.
D. COALESCE stops evaluating the list of expressions when it finds the first null value.
E. NVL can have any number of expressions in the list.
F. COALESCE stops evaluating the list of expressions when it finds the first non-null value.

정답：A,F

설명：
A . This statement is false. In NVL2, the first expression is returned if it is not null.
B . This statement is false. NVL2 takes exactly three arguments, not any number of expressions.
C . This statement is false. COALESCE stops evaluating its list of expressions as soon as it finds the first non-null value.
D . This is true. COALESCE returns the first non-null expression in its list.
E . This statement is true. NVL requires the first and second expressions to be of the same or compatible data types because it returns the first expression if it is not null, otherwise it returns the second.
F . This statement is false. NVL takes exactly two arguments, not any number.

F. When issuing a SELECT FOR UPDATE statement after a CREATE TABLE AS SELECT statement was issued in the same session

정답：C,E,F

설명：
Substitution variables in Oracle are used to replace a value dynamically during the execution of SQL statements. The behavior of these variables is well-documented:
* C. A substitution variable prefixed with & always prompts only once for a value in a session: This is true. In a session, when you use a single ampersand (&), SQL*Plus or SQL Developer will prompt for the value the first time the variable is encountered. The value for this variable will then be reused for the remainder of the session unless it is redefined.
* D. A substitution variable can be used with any clause in a SELECT statement: Substitution
* variables can be placed in any part of a SQL statement, including the SELECT, WHERE, GROUP BY, ORDER BY, etc. They are not limited to any specific clause.
References:
* Oracle SQL*Plus User's Guide and Reference, which discusses substitution variables.
