Merge and XMLTYPE

Hello,

I try to merge a XML file in a table

Here is the query :

DECLARE
 v_xml XMLTYPE;
 BEGIN

v_XML := XMLTYPE(bfilename('FICHIER_IN_FB', 'events.xml'), nls_charset_id('AL32UTF8'));

MERGE INTO EVT_EVENTS t
USING 
(
  SELECT x.*
  FROM XMLTABLE
  ( 
   'events'
  passing v_xml
   columns EV_ID VARCHAR2(32) PATH '@id',  
  EV_TITLE VARCHAR(30) PATH 'title',
  EV_SUBTITLE VARCHAR2(30) PATH 'subTitle',
  EV_SHORT_DESCRIPTION VARCHAR2(1000) PATH 'shortDescription',
  EV_IS_WITHOUT_SESSION varchar2(30) PATH 'isWithoutSession',
  EV_IS_TICKET_MANDATORY varchar2(50) PATH 'isTicketHolderMandatory',
  EV_IS_CLIENT_INFORMATION varchar2(50) PATH 'isClientInformationMandatory',
  EV_STATUS varchar2(5) PATH 'status',
  EV_CREATION_DATE varchar2(30) PATH 'creationDate',
  EV_MODIFICATION_DATE varchar2(30) PATH 'modificationDate',
  EV_ORGANIZATION varchar2(30) PATH 'organization',
  EV_MIN_PRICE varchar2(30) PATH 'minPrice',
  EV_MAX_PRIZE varchar2(30) PATH 'maxPrice',
  EV_PLACE_ID varchar2(30) PATH 'place/@id'
  )x
) src
ON (t.EV_ID = src.EV_ID)

WHEN MATCHED THEN
  UPDATE SET 
  t.EV_TITLE = src.EV_TITLE,
  t.EV_SUBTITLE = src.EV_SUBTITLE ,
  t.EV_SHORT_DESCRIPTION = src.EV_SHORT_DESCRIPTION,
  t.EV_IS_WITHOUT_SESSION = src.EV_IS_WITHOUT_SESSION,
  t.EV_IS_TICKET_MANDATORY = src.EV_IS_TICKET_MANDATORY,
  t.EV_IS_CLIENT_INFORMATION = src.EV_IS_CLIENT_INFORMATION,
  t.EV_STATUS = src.EV_STATUS,
  t.EV_CREATION_DATE = src.EV_CREATION_DATE,
  t.EV_MODIFICATION_DATE = src.EV_MODIFICATION_DATE,
  t.EV_ORGANIZATION = src.EV_ORGANIZATION,
  t.EV_MIN_PRICE = src.EV_MIN_PRICE ,
  t.EV_MAX_PRIZE = src.EV_MAX_PRIZE,
  t.EV_PLACE_ID = src.EV_PLACE_ID,
  t.ev_current_date = sysdate

WHEN NOT MATCHED THEN
  INSERT (t.EV_TITLE,
  t.EV_SUBTITLE,
  t.EV_SHORT_DESCRIPTION,
  t.EV_IS_WITHOUT_SESSION,
  t.EV_IS_TICKET_MANDATORY,
  t.EV_IS_CLIENT_INFORMATION,
  t.EV_STATUS,
  t.EV_CREATION_DATE,
  t.EV_MODIFICATION_DATE,
  t.EV_ORGANIZATION,
  t.EV_MIN_PRICE,
  t.EV_MAX_PRIZE,
  t.EV_PLACE_ID,
  t.ev_current_date)
  VALUES (src.EV_TITLE,
  src.EV_SUBTITLE, 
  src.EV_SHORT_DESCRIPTION,
  src.EV_IS_WITHOUT_SESSION,
  src.EV_IS_TICKET_MANDATORY,
  src.EV_IS_CLIENT_INFORMATION,
  src.EV_STATUS,
  src.EV_CREATION_DATE,
  src.EV_MODIFICATION_DATE,
  src.EV_ORGANIZATION,
  src.EV_MIN_PRICE,
  src.EV_MAX_PRIZE,
  src.EV_PLACE_ID,
  sysdate
   );
end;

Can you explain me what I'm doing wrong ?

Thanks

Cheers
