OdbcDataReader.Read

Hallo,

ich habe eine bestehende Datenbank-Applikation zu unterhalten, welche jedoch
Probleme bereitet.

Die DB-Anfrage dauert eine Ewigkeit, und sehr oft schlaegt die Abfrage auch
fehl.

Eine generelle Frage, wird beim Aufruf von:

functionxy(selectWorklogCmd.ExecuteReader(), dest); das Select-Statement
schon ausgefuehrt? Oder erst in functionxy an der Stelle:

while (reader.Read) ?

Genau an dieser dauert es naemlich ewig lange, wenn die Abfrage ueberhaupt
erfolgreich ist..

vielen dank fuer die hilfe.

gruss
