I have come across some scenario based on the example given below:
TAB1
COL1 COL2
----- -----
A 10
B 20
C 30
D 40
E 50

DECLARE c1 CURSOR WITH HOLD FOR
SELECT * FROM tab1 ORDER BY col_1;
OPEN c1;
FETCH c1;
FETCH c1;
FETCH c1;
COMMIT;
FETCH c1;
CLOSE c1;
FETCH c1;
What would be the last value obtained for COL2?
40 OR 50. Pls give some explanation as well !

interview question?

progam will not precompile: col_1 is an undefined name.
and if you meant COL1 :

the last value obtained for col2 is 40
the last error received is -501

No explanation should be needed by anyone with basic SQL knowledge.
