NEW QUESTION # 110
Which statement is true about Enterprise Manager (EM) express in Oracle Database 12c?

A. You can create and configure pluggable databases by using EM express.
B. You can perform basic administrative tasks for pluggable databases by using the EM express interface.
C. You cannot start up or shut down a database Instance by using EM express.
D. By default, EM express is available for a database after database creation.
E. You can use EM express to manage multiple databases running on the same server.

Answer: D

Explanation:
Note:
*Oracle Enterprise Manager Database Express (EM Express) is a web-based database management tool that is built inside the Oracle Database. It supports key performance management and basic database administration functions. From an architectural perspective, EM Express has no mid-tier or middleware components, ensuring that its overhead on the database server is negligible.
Incorrect:
Not B: For one database at a time.
Not C, Not E: Enterprise Manager Database Express features can be used against non-CDBs or Oracle RAC database instances.
Not D:After the installation, your instance is started and your database is open. In the future, there will be times, perhaps for doing database maintenance or because of a power or media failure, that you shut down your database instance and later restart it.

NEW QUESTION # 111
You execute these commands:
SQL> DEFINE hiredate = '01-APR -2011';
SQL> SELECT employee_id, first_name, salary FROM employees WHERE hire date > &hiredate AND manager_id >&mgr_id; For which substitution variables will you be prompted?

A. &hiredate and &mgr_id
B. none
C. only &mgr_id
D. only &hiredate

Answer: C

Explanation:
* D. only &mgr_id: Since the hiredate variable is already defined before the SELECT statement, you will not be prompted for &hiredate again. However, &mgr_id has not been defined, so you will be prompted for this substitution variable.

NEW QUESTION # 112
Examine the data in the NEW_EMPLOYEES table:

Examine the data in the EMPLOYEES table:

You want to:
1. Update existing employee details in the EMPLOYEES table with data from the NEW EMPLOYEES table.
2. Add new employee detail from the NEW_ EMPLOYEES able to the EMPLOYEES table.
Which statement will do this:

A. MERGE INTO employees e
USING new employees ne
WHERE e.employee_id = ne.employee_ id
WHEN MATCHED THEN
UPDATE SET e.name = ne.name, e.job_id = ne.job_id,e.salary =ne. salary
WHEN NOT MATCHED THEN
INSERT VALUES (ne. employee_id,ne.name, ne.job_id,ne.salary) ;
B. MERGE INTO employees e
USING new_employees n
ON (e.employee_id = ne.employee_id)
WHEN MATCHED THEN
UPDATE SET e.name = ne.name, e.job id = ne.job_id,e.salary =ne. salary
WHEN NOT MATCHED THEN
INSERT VALUES (ne. employee_id,ne.name,ne.job_id,ne.salary);
C. MERGE INTO employees e
USING new_employees n
WHERE e.employee_id = ne.employee_id
WHEN FOUND THEN
UPDATE SET e.name=ne.name,e.job_id =ne.job_id, e.salary=ne.salary
WHEN NOT FOUND THEN
INSERT VALUES (ne.employee_ id,ne.name,ne.job id,ne.salary) ;
D. MERGE INTO employees e
USING new employees ne
ON (e.employee_id = ne.employee_id)
WHEN FOUND THEN
UPDATE SET e.name =ne.name, e.job_id=ne.job_id, e.salary =ne.salary
WHEN NOT FOUND THEN
INSERT VALUES (ne.employee_id,ne.name,ne.job_id,ne.salary) ;

Answer: B

Explanation:
The correct answer to perform the specified update and insert operations is to use the MERGE statement, which is designed to facilitate such "upsert" operations (update or insert).
A . The syntax is incorrect; the WHERE clause is not used with MERGE.
B . This is the correct syntax and use of the MERGE statement. It uses the ON clause to specify the join condition, and it provides actions for WHEN MATCHED and WHEN NOT MATCHED situations.
C . The keywords FOUND and NOT FOUND are not valid in the context of the MERGE statement in Oracle SQL.
D . Similar to option A, the syntax is incorrect because MERGE uses an ON clause, not a WHERE clause, and the keywords FOUND and NOT FOUND are incorrect.
The correct syntax of a MERGE statement includes defining a condition using the ON clause to determine how rows from the source and target tables are matched, then specifying the actions for when rows match (WHEN MATCHED) and when they do not match (WHEN NOT MATCHED).
