An application contains the statements shown below:
DECLARE csr1 CURSOR WITH HOLD FOR SELECT * FROM employee;
OPEN csr1;
FETCH csr1;
DECLARE csr2 CURSOR FOR SELECT * FROM employee;
OPEN csr2;
COMMIT;
CLOSE csr1;
When will cursor CSR1 lose position?

INSERT INTO table1 VALUES(1,11);
INSERT INTO table1 VALUES(2,11);
SAVEPOINT sp1 ON ROLLBACK RETAIN CURSORS;
INSERT INTO table1 VALUES(3,11);
INSERT INTO table1 VALUES(4,11);
INSERT INTO table1 VALUES(5,11);
SAVEPOINT sp2 ON ROLLBACK RETAIN CURSORS;
INSERT INTO table1 VALUES(6,11);
INSERT INTO table1 VALUES(7,11);
ROLLBACK TO SAVEPOINT sp2;
INSERT INTO table1 VALUES(8,11);
SAVEPOINT sp3 ON ROLLBACK RETAIN CURSORS;
INSERT INTO table1 VALUES(9,11);
ROLLBACK;
Application1 executes the SQL statements shown in the exhibit against table TABLE1 in manual
commit mode. How many rows will be inserted in TABLE1?

CREATE TABLE store(sid INTEGER, info XML);
INSERT INTO store VALUES (1,
'<storeinfo sid="1">
<name>ABCDEF</name>
</storeinfo>');
INSERT INTO store VALUES (2,
'<storeinfo sid="2">
<name>FEDCBA</name>
</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 $name := fn:substring($store/name, 1, 3),
$lcase := fn:lower-case($name)
return $lcase
What is the output?

GRANT CONNECT, IMPLICIT_SCHEMA ON DATABASE TO user1;
GRANT INSERT ON TABLE s1.t1 TO user1;
GRANT CONTROL ON s1.v1 TO user1;
