Re: Embedded SQL

Jerry, I was more concerned with the OPEN and CLOSE cursors. Thanks.

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;
