query has no destination for result data

Hi,

I'm a beginner in postgresql. I get the below error. Could you help me
to fix this one?

ERROR:  query has no destination for result data
HINT:  If you want to discard the results of a SELECT, use PERFORM instead.

open c1;
Loop
fetch c1 into query_rec;

raise notice 'Record %', query_rec.field1;
end;
End loop;
Return 'ok';
end;
