end;As there is change in requirement now I need to read the multiple supplier sites at the header level. Current this is my structure please give an idea how to read the mulitple sites as one record, probably i can increase the supplier site columns at table level so as to capture second site level information.
But if in case if i receive that time it should not fail please provide some good solution for this issue.
Thanks in advance for your help.

Answer 1

Hi odie,
Thanks for your response. But here my supplier site will always be maxiumum 2 times and minimum 1 time. My thinking is to fit this one in the existing code by repeating the supplier site only like this
          supp_site_id                       NUMBER         path    'HEADER/SUPPLIER/SITES/SITE/ID',
          supp_site_name                     VARCHAR2(140)  path    'HEADER/SUPPLIER/SITES/SITE/NAME',

          supp_site_country_code             VARCHAR2(2 )   path    'HEADER/SUPPLIER/SITES/SITE/COUNTRY_CODE',
          supp_site_province                 VARCHAR2(25 )  path    'HEADER/SUPPLIER/SITES/SITE/PROVINCE',
          supp_site_state                    VARCHAR2(25 )  path    'HEADER/SUPPLIER/SITES/SITE/STATE',
          supp_site_city                     VARCHAR2(25 )  path    'HEADER/SUPPLIER/SITES/SITE/CITY',
          supp_site_area_code                VARCHAR2(10 )  path    'HEADER/SUPPLIER/SITES/SITE/AREA_CODE',
          supp_site_zip                      VARCHAR2(20 )  path    'HEADER/SUPPLIER/SITES/SITE/ZIP',
          supp_site_region_code              VARCHAR2(3 )   path    'HEADER/SUPPLIER/SITES/SITE/REGION_CODE',
          supp_site_id2                       NUMBER         path    'HEADER/SUPPLIER/SITES/SITE/ID',
          supp_site_name2                     VARCHAR2(140)  path    'HEADER/SUPPLIER/SITES/SITE/NAME',
          supp_site_phone2                    VARCHAR2(23)   path    'HEADER/SUPPLIER/SITES/SITE/PHONE',
          supp_sit_phone_ext2                 VARCHAR2(4 )   path    'HEADER/SUPPLIER/SITES/SITE/PHONE_EXTENSION',
          supp_site_fax2                      VARCHAR2(23 )  path    'HEADER/SUPPLIER/SITES/SITE/FAX',
          supp_site_email2                    VARCHAR2(100 ) path    'HEADER/SUPPLIER/SITES/SITE/EMAIL',
          supp_site_add_line1_2                VARCHAR2(254 ) path    'HEADER/SUPPLIER/SITES/SITE/ADDRESS_LINE1',
          supp_site_add_line2_2                VARCHAR2(35 )  path    'HEADER/SUPPLIER/SITES/SITE/ADDRESS_LINE2',
          supp_site_add_line3_2                VARCHAR2(35 )  path    'HEADER/SUPPLIER/SITES/SITE/ADDRESS_LINE3',

          supp_site_province_2                 VARCHAR2(25 )  path    'HEADER/SUPPLIER/SITES/SITE/PROVINCE',
          supp_site_state_2                    VARCHAR2(25 )  path    'HEADER/SUPPLIER/SITES/SITE/STATE',
          supp_site_city_2                     VARCHAR2(25 )  path    'HEADER/SUPPLIER/SITES/SITE/CITY',
          supp_site_area_code_2                VARCHAR2(10 )  path    'HEADER/SUPPLIER/SITES/SITE/AREA_CODE',
          supp_site_zip_2                      VARCHAR2(20 )  path    'HEADER/SUPPLIER/SITES/SITE/ZIP',
          supp_site_region_code_2              VARCHAR2(3 )   path    'HEADER/SUPPLIER/SITES/SITE/REGION_CODE',As this table I am being used in many areas, it will be problem for me if try to go for different levels of tables. Or else can it be possible to read only once
I mean only the first in the xml tags and leave the second xml. As there is not much significant for the second one.
I appreciate your ideas on this, as the structure we are following is to rigid so I don't have much options to explore, please provide me your inputs in this context.
Thanks for your help.
Regards
Nagendra
