問題 #326
Examine the description of the PRODCTS table which contains data:

Which two are true?

A. The PROD_ ID column data type can be changed to VARCHAR2 (2).
B. The EXPIRY DATE column data type can be changed to TIME STAMP.
C. The EXPIRY DATE column cannot be dropped.
D. The PROD ID column can be renamed.
E. The PROD NAME column cannot have a DEFAULT clause added to it.

答案：B,D

問題 #327
Which two statements are true about views?

A. Theethi CHEcK clause prevents certalin rows from being updated or inserted in the underying table through the view.
B. Views can be updated without the need to re-grant privileges on the view.
C. The wITH CHECK clause prevents certain rows from being displayed when querying the view.
D. Tables in the defining query of a view must always exist in order to create the view.
E. Views can be indexed.

答案：B,D

解題說明：
Views in Oracle have specific properties regarding how they can be used and what limitations apply to them:
A; Oracle does not allow indexing directly on views. However, a view can display data from indexed tables.
B; The WITH CHECK OPTION clause on a view prevents DML operations that would result in rows that do not satisfy the view's filter criteria. It doesn't prevent certain rows from being updated or inserted in the underlying table through the view per se.
C; The tables (or other views) referenced in the creating query of a view must exist at the time the view is created, making this statement true.
D; Views do not require privileges to be re-granted when the view is updated; they are separate from the underlying object privileges, making this statement true.
E; The WITH CHECK OPTION clause is used to ensure that all data modifications through the view are consistent with the view's defining query, not to prevent rows from being displayed.
References:
* Oracle Database SQL Language Reference, 12c Release 1 (12.1): "CREATE VIEW"
* Oracle Database Concepts, 12c Release 1 (12.1): "Views"

D. A parent key column in the table cannot be dropped.
E. The column in a composite PRIMARY KEY with the CASCADE option can be dropped.

答案：C

問題 #329
View the Exhibit and examine the structure in the EMPLOYEES tables.
Evaluate the following SQL statement:
SELECT employee_id, department_id
FROM employees
WHERE department_id= 50 ORDER BY department_id
UNION
SELECT employee_id, department_id
FROM employees
WHERE department_id=90
UNION
SELECT employee_id, department_id
FROM employees
WHERE department_id=10;
What would be the outcome of the above SQL statement?

A. The statement would not execute because the positional notation instead of the column name should be used with the ORDER BY clause.
B. The statement would not execute because the ORDER BY clause should appear only at the end of the SQL statement, that is, in the last SELECT statement.
C. The statement would execute successfully but it will ignore the ORDER BY clause and display the rows in random order.
D. The statement would execute successfully and display all the rows in the ascending order of DEPARTMENT_ID.

答案：B

問題 #330
Which two statements will convert the string Hello world to ello wozid?

A. SELECT LOWER (SUBSTR('Hello World', 2)) FROM DUAL;
B. SELECT LOWER(TRIM('H' FROM 'Hello World')) FROM DUAL;
C. SELECT INITCAP(TRIM('H' FROM 'Hello World')) FROM DUAL;
D. SELECT SUBSTR('Hello world', 2) FROM DUAL;
E. SELECT LOWER (SUBSTR('Hello World, 2, 1)) FROM DUAL;

答案：A,D

解題說明：
To convert the string "Hello World" to "ello wozid":
* Option B: SELECT LOWER(SUBSTR('Hello World', 2)) FROM DUAL;
* This will remove the first character and convert the rest to lowercase, but it will not change the
'rld' to 'zid'.
* Option D: SELECT SUBSTR('Hello world', 2) FROM DUAL;
* This will remove the first character, but the rest of the string remains unchanged and not converted to lowercase.
Options A, C, and E are incorrect because:
* Option A: SUBSTR is incorrect here because it is only getting one character instead of the entire string minus the first character.
* Option C: While TRIM removes the 'H', LOWER converts all characters to lowercase, but it doesn't address the 'rld' to 'zid' change.
* Option E: INITCAP and TRIM will not achieve the desired conversion of 'rld' to 'zid'.

問題 #331
