  I want the extract the ids from the table where pmt contains the child node (asset) contains .zip
for example http://download.p4c.abc.com/files/4/46pfl8008s_12/46pfl8008s_12_qsg_deu.zip
Then, I tried like this...
  select r.* from
   (SELECT xmltype(pmt) object_value
                 FROM PRODUCT_TR_PMT
                 XMLTABLE
                                 'for $Product  in $TEST/Products/Product/Assets/Asset
                                     return <RESULT>
                                               $Product                     
                                            </RESULT>'
                                 passing OBJECT_VALUE as "TEST"   
                                 columns Asset path 'Asset' 
                             ) r;
ORA-02263: need to specify the datatype for this column
  Could you kindly help.
Thanks

Answer 1

Blob storage we (db folks) dont have any control its from application standard design.
If necessary, i can create function blob to clob.
Kindly help me in extracting child node which contains zip.
   select r.* from
   (SELECT xmltype(pmt) object_value
                 FROM PRODUCT_TR_PMT
                 XMLTABLE
                                 'for $Product  in $TEST/Products/Product/Assets/Asset
                                     return <RESULT>
                                               $Product                     
                                            </RESULT>'
                                 passing OBJECT_VALUE as "TEST"   
                                 columns Asset varchar2(255) path 'Asset' 
                             ) r;
ORA-06553: PLS-306: wrong number or types of arguments in call to 'XMLTYPE'Thanks
