2. The statement below was used to create a cursor named CSR1:
DECLARE csr1 DYNAMIC SCROLL CURSOR FOR
SELECT * FROM employee;
After fetching all of the rows in the result set associated with cursor CSR1, which two statements can be
used to fetch the data starting at the end of the result set? (Choose two.)

3. Click the Exhibit button.
CREATE TABLE store(sid INTEGER, info XML);
INSERT INTO store VALUES (1,
'<storeinfo sid="1">
<name>Grocery A</name>
<items>
<fruit><name>Mango</name><price>1.20</price></fruit>
<fruit><name>Apple</name><price>0.50</price></fruit>
<dessert><name>Ice Cream</name><price>6.00</price></dessert>
</items>
</storeinfo>');
Given the statements shown in the exhibit, a user executes the query shown below:
XQUERY for $store in db2-fn:xmlcolumn('STORE.INFO')/storeinfo
let $items := $store/items/fruit, $count := fn:count($items)
return <itemcount>$count</itemcount>
What is the output?
A. 2
B. <itemcount>2</itemcount>
C. <itemcount>1</itemcount>
D. <itemcount>$count</itemcount>
Answer: D
4. You have created a stored procedure (MULTIRESULTS()) on the server which will return multiple result
sets. While developing a PHP application using the IBM_DB2 extension, you want to call the stored
procedure. The code shown below will execute the stored procedure:
$stmt = db2_exec($conn, 'CALL multiResults()');
How can you fetch all of the result sets from $stmt?
A. Call db2_fetch_object($stmt) for the first result set; call db2_next_result($stmt) for more result sets.
B. Call db2_next_result($stmt) for each result set.
C. Call db2_fetch_object($stmt) for each result set.
D. Call db2_next_result($stmt) for each result set; call db2_fetch_object($stmt) for each row in the result
set.
Answer: A
5. An existing table has the definition shown below:
CREATE TABLE hr.employees (
empid INTEGER NOT NULL PRIMARY KEY,
deptno INTEGER,
authid VARCHAR(255),
salary DECIMAL (10,2),
commission DECIMAL (5,3) DEFAULT 0,
benefits XML )
Only members of the HR_ADMIN group have privilege to SELECT, INSERT, UPDATE, or DELETE from
the HR.EMPLOYEES table. A Web-based application is under development that connects to the
database with a user's AUTHID and enables a user to see their record. No other records are visible.
Which type of database object can be created by a member of the HR_ADMIN that provides the
necessary information without changing the privileges on the HR.EMPLOYEES table?
A. trigger
B. view
C. alias
D. index
