J'ai vu un package appelé as_xlsx par Anton Scheffer, Créez un fichier Excel avec PL/SQL et cela a résolu mon problème. Je l'ai également modifié un peu pour mettre les noms de feuille de calcul et pour autoriser SYS_REFCURSOR comme Paramètre au lieu d'un VARCHAR2 comme requis dans mon article précédent (Renvoyer l'instruction SQL d'un curseur explicite).
J'ai ajouté ceci dans la spécification de package pour la surcharge de procédure :
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
);
J'ai ajouté ceci dans le corps du package pour la surcharge de procédure (remarque :les commentaires de ligne étaient des lignes que j'ai modifiées) :
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
)
is
t_sheet pls_integer;
t_c integer;
t_col_cnt integer;
t_desc_tab2 dbms_sql.desc_tab2;
t_desc_tab dbms_sql.desc_tab;
d_tab dbms_sql.date_table;
n_tab dbms_sql.number_table;
v_tab dbms_sql.varchar2_table;
t_bulk_size pls_integer := 200;
t_r integer;
t_cur_row pls_integer;
t_d number;

Ceci est un exemple de bloc dans ma demande simultanée qui crée le fichier :
Procedure EMP_ROSTER_REPORT (p_empno per_all_people_f.employee_number%type

, p_email_add per_all_people_f.email_address%type)
is

l_directory VARCHAR2(30) := 'EXT_TAB_DATA';
l_filename VARCHAR2(100);
emp_cur SYS_REFCURSOR;
l_message varchar2(100);
g_stage varchar2(100);
g_zipped_blob blob;
cursor p_payroll_cur is
select payroll_id
, payroll_name
, business_group_id
from pay_all_payrolls_f
where business_group_id = p_bg_id;

as_xlsx.query2sheet( p_cur => emp_cur -- Uses Sys_RefCursor Instead of Dynamic SQL (Varchar2)

as_xlsx.freeze_pane( 1,1 ); -- Freeze the topmost and rightmost pane in the Excel Sheet
end loop;

J'espère que cela aide quelqu'un! :)
