Обсуждение: Is this possible / slow performance?

Hi every one,


Why does this take forever (each query is sub second when done seperately)?
Is it because I cannot open two cursors in the same transaction?

begin;

declare SQL_CUR01 cursor for
SELECT A.ordernummer, B.klantnummer FROM "orders" A LEFT OUTER JOIN "klt_alg" B ON A.Klantnummer=B.Klantnummer ORDER BY
A.klantnummer;
fetch 100 in SQL_CUR01;

declare SQL_CUR02 cursor for
SELECT A.ordernummer, B.klantnummer FROM "orders" A LEFT OUTER JOIN "klt_alg" B ON A.Klantnummer=B.Klantnummer ORDER BY
A.klantnummerdesc; 
fetch 100 in SQL_CUR02;

commit;


TIA
