Hi All, a while back I was helped on here with an XML query. The Query works but I am having trouble querying out a new object (signature URL)


The query returns all the required information, except not on the URL in signatureURL.


This is the Query.
SELECT DISTINCT 
       c.taxid,
       CASE WHEN c.taxid != '0' OR LENGTH(c.id) = 5 THEN c.taxid ELSE REGEXP_SUBSTR(c.id, '^[^- ]+') END chain,
       CASE WHEN LENGTH(c.id) = 5 THEN c.id ELSE REGEXP_SUBSTR(c.id, '[^- ]+$') END customer,
       CASE WHEN c.taxid is null then '0' else c.taxid end as taxid,
       c.mtime,
       o.owner,
       o.signature,
       o.sku,
       o.qty
  FROM xml_data_tab t,
       XMLTABLE(
           '//customer'
           PASSING t.xml_data
           COLUMNS cust_seq FOR ORDINALITY,
                   id VARCHAR2(50) PATH '/customer/id',
                   taxid VARCHAR2(50) PATH '/customer/taxID',
                   mtime VARCHAR2(50) PATH '/customer/billTo/mtime'
       ) c,
       XMLTABLE(
           '//lines'
           PASSING t.xml_data
           COLUMNS line_seq FOR ORDINALITY, node XMLTYPE PATH '.'
       ) l,
       XMLTABLE(
           '//object'
           PASSING l.node
           COLUMNS 
                   signature VARCHAR2(100) PATH '/object/signatureURL',
                   owner VARCHAR2(50) PATH '/object/owner',
                   sku VARCHAR2(50) PATH '/object/sku',
                   qty VARCHAR2(50) PATH '/object/qty'
       ) o
 WHERE  l.line_seq = c.cust_seq

Your objects aren't children of the l.node, they are at the parent, so you need to pass in the whole document

change
     PASSING l.node
to
     PASSING t.xml_data

alternatively, remove the "o" xmltable, and combine with the customer extractions

   SELECT DISTINCT
          c.taxid,
          CASE
              WHEN c.taxid != '0' OR LENGTH(c.id) = 5 THEN c.taxid
              ELSE REGEXP_SUBSTR(c.id, '^[^- ]+')
          END
              chain,
          CASE WHEN LENGTH(c.id) = 5 THEN c.id ELSE REGEXP_SUBSTR(c.id, '[^- ]+$') END customer,
          CASE WHEN c.taxid IS NULL THEN '0' ELSE c.taxid END AS taxid,
          c.mtime,
          c.owner,
          c.signature,
          c.sku,
          c.qty
     FROM xml_data_tab t,
          XMLTABLE(
              '/object'
              PASSING t.xml_data
              COLUMNS cust_seq FOR ORDINALITY,
                      id VARCHAR2(50) PATH '/object/customer/id',
                      taxid VARCHAR2(50) PATH '/object/customer/taxID',
