It seems reasonable that Fetch would be expensive, and probably is. But for a few thousand records it's hardly noticeable.

It just so happens that I wrote a program today tat uses Fetch over a file with > 1500 records. Finished in the blink of an eye. And, since I had no idea how many records there would be in the table, it wasn't optimized for a set number of rows.

The following embedded SQL is going to return only one record in the result set. Do I need to use CURSOR logic (declare , open, fetch, close) to get the values into my variables as shown. Or, is there another way (VALUES INTO, etc.). I ask because it seems that using the CURSOR logic is very expensive. I need to execute this code several thousand times. Thanks.

exec sql
declare c3 cursor for
SELECT office, chart,
sum(value(dec((dec((substr(undata,4,7)),7,0)) / 100),7,2))
FROM NHISxx
WHERE rectyp = 'PA' and office = :svOffice and chart = :svChart
and idate(crtdat,'*YMD') between :pStrDate and :pEndDate
GROUP BY office, chart;

exec sql
open c3;

exec sql
fetch next from c3
into :hsOffice,
:hsChart,
:hsPmtAmt;

exec sql
close c3;
