Hi
Please help, I have been asked why XML string functions do this, which is why does the second statement below return no rows. No matter what is on the select statement, they can select as many columns as they want but the XML function breaks it as soon as it is added.
1) select aud_id,act_typ,right(act_typ::text,1),fpp_cde,obo_aud_id,obo_aud_id||sku_cde as "Key" from sku_tran join audit using (aud_id) join action_typ using (act_typ) join branch using (br_cde) join sku using (sku_cde) where obo_aud_id=5252005 and audit.fpp_cde between '201408' and '201412' and (right(act_typ::text,1) = '5') and act_typ between 76000 and 76999;
aud_id | act_typ | right | fpp_cde | obo_aud_id | Key
2585912 | 76005 | 5 | 201408 | 5252005 | 525200510053486
(1 row)
2) select aud_id,act_typ,right(act_typ::text,1),fpp_cde,obo_aud_id,(unnest(xpath('.//checksumBr/text()', aud_xml::xml)))::text||obo_aud_id||sku_cde as "Key" from sku_tran join audit using (aud_id) join action_typ using (act_typ) join branch using (br_cde) join sku using (sku_cde) where obo_aud_id=5252005 and audit.fpp_cde between '201408' and '201412' and (right(act_typ::text,1) = '5') and act_typ between 76000 and 76999;
aud_id | act_typ | right | fpp_cde | obo_aud_id | Key
(0 rows)
