Records not returned

Question

hi! i've some codes:
For i in 1..4 loop
gp:='pollquestion_rec.Option'||i;
htp.p(gp);

pls advise.

Answer 1

For i in 1..4 loop
gp:='pollquestion_rec.Option'||i;
htp.p(gp);
htp.p('<BR>');
end loop;
in the above piece of code,pollquestion_rec is a cursor and option is the resultset.
and i takes values of the loop counter..ie...1,2,3,4.
since a quote is given ' pollquestion_rec.option'||i
you will get an output
as
pollquestion_rec.option1
pollquestion_rec.option2
pollquestion_rec.option3
pollquestion_rec.option4
if you remove the quotes, then you will get the actual value from database.
the following example may help you.
/* with quote */
