Hi,
I have below query used in Oracle but while migrating to Postgres this code is not supported in Postgres.
Could you please tell me how to resolve this?
SELECT p.id_po, p.line_number, replace(replace(replace(RTRIM(XMLAGG(XMLELEMENT(name C, regexp_replace(p.protocol_number,'([[:cntrl:]])','', 'g'))ORDER BY 1), ',' ) ,'</C><C>','/'),'<C>',''),'</C>','') AS protocol_number
,replace(replace(replace(RTRIM(XMLAGG(XMLELEMENT(name C, regexp_replace(p.protocol_status,'([[:cntrl:]])','', 'g'))ORDER BY 1), ',' ) ,'</C><C>','/'),'<C>',''),'</C>','') AS protocol_status
,replace(replace(replace(RTRIM(XMLAGG(XMLELEMENT(name C, regexp_replace(p.protocol_approver,'([[:cntrl:]])','', 'g'))ORDER BY 1), ',' ) ,'</C><C>','/'),'<C>',''),'</C>','') AS protocol_approver
,max(p.protocol_date) AS protocol_date
,replace(replace(replace(RTRIM(XMLAGG(XMLELEMENT(name C, regexp_replace(p.protocol_nota,'([[:cntrl:]])','', 'g'))ORDER BY 1), ',' ) ,'</C><C>','/'),'<C>',''),'</C>','') AS protocol_nota
,sum(coalesce(p.protocol_value,0)) protocol_value
FROM podl_extended_protocol p
where upper(p.protocol_status) not in ('REJEITADO','ELIMINADO')
group by p.id_po, p.line_number
Thanks,
Bimal
