CommandTable Cystal Fehler melden

Question

Ich habe einen Crystal Report, der mit einem komplexen SQL geschrieben wurde, und ich versuche, das mit der Crystal Report Java API aufzurufen. Diesem Bericht ist ein Command-Objekt zugeordnet.

1. Ich lade den Bericht und stelle die Verbindungsparameter ein.
2. Dann versuche ich die Verbindungsinformationen auf das aktuelle JDBC-Profil einzustellen. Bedeutung Testumgebung Anmeldeinformationen.

Ich bekomme eine Ausnahme. Ich habe versucht mit Version 11. Version 12 beide. Keiner von ihnen scheint zu arbeiten.

Ich bekomme die Ausnahme, wenn ich den folgenden Code aufrufen. Dieses Stück Code funktioniert gut mit Berichten ohne "Befehl" sqls.

try{ 
    clientDoc.getDatabaseController().setTableLocation(
    origTable, newTable); 
}catch(Exception ex){ 
    ex.printStackTrace(); 
} 

Siehe unten für den gesamten Code. Bitte antworten Sie, wenn jemand weiß, wie dies zu umgehen ist.

Answer 1

hinzufügen nach dieser Zeile von Ihnen

connectionInfo.setPassword(DB_PASSWORD); 
newTable.setConnectionInfo(connectionInfo); 
//This will add connection parameters to the new table 

Statt

clientDoc.getDatabaseController().setTableLocation(origTable, newTable); 

diese ersetzen mit

clientDoc.getDatabaseController().setTableLocation (newTable, tables.getTable(i));
