Ich habe ein Paket namens as_xlsx gesehen von Anton Scheffer, Erstellen Sie eine Excel-Datei mit PL/SQL und es hat mein Problem behoben. Ich habe es auch ein wenig modifiziert, um Arbeitsblattnamen einzufügen und SYS_REFCURSOR zuzulassen als Parameter anstelle eines VARCHAR2 wie in meinem vorherigen Beitrag (Rückgabe der SQL-Anweisung eines expliziten Cursors) erforderlich.
Ich habe dies in der Paketspezifikation für das Überladen von Prozeduren hinzugefügt:
procedure query2sheet
( p_cur IN OUT SYS_REFCURSOR
, p_column_headers boolean := true
, p_directory varchar2 := null
, p_filename varchar2 := null
, p_sheet pls_integer := null
, p_sheetname varchar2 := null
);
Ich habe dies im Paketkörper für das Überladen von Prozeduren hinzugefügt (Anmerkung:Die Zeilenkommentare waren Zeilen, die ich geändert habe):
procedure query2sheet
( p_cur IN OUT SYS_REFCURSOR
, p_column_headers boolean := true
, p_directory varchar2 := null
, p_filename varchar2 := null
, p_sheet pls_integer := null
, p_sheetname varchar2 := null
)

t_col_cnt integer;

Hoffe das hilft jemandem! :)
