從列中提取xml值並將其插入到另一個數據庫中

Question

我有一個數據庫，其中的Blob列包含XML文件。 我想在此數據庫中檢索存儲在Blob中的XML標簽的值，以在另一個數據庫的它們各自的列中詳細說明它們。

因此，如何獲取x標記的值（ 如下面的SQL查詢所示 ）並將其插入到其他數據庫的x列中？

SELECT id,

EXTRACTVALUE(Value(p), 'activites/categorieProjet/text()') As categorieProjet,
EXTRACTVALUE(Value(p), 'activites/coutParBeneficiaire/text()') As coutParBeneficiaire,
EXTRACTVALUE(Value(p), 'activites/etat/text()') As etat,
EXTRACTVALUE(Value(p), 'activites/idActivite/text()') As IdActivite,
EXTRACTVALUE(Value(p), 'activites/nbreDeBeneficiaires/text()') As nbreDeBeneficiaires,
EXTRACTVALUE(Value(p), 'activites/nbsession/text()') As nbsession,
EXTRACTVALUE(Value(p), 'activites/nom/text()') As nom,
EXTRACTVALUE(Value(p), 'activites/objectifSpecifique/text()') As objectifSpecifique,
EXTRACTVALUE(Value(p), 'activites/participation/text()') As participation,
EXTRACTVALUE(Value(p), 'activites/publicConcerne/text()') As publicConcerne,
EXTRACTVALUE(Value(p), 'activites/thematique/text()') As thematique,
EXTRACTVALUE(Value(p), 'activites/typeActivite/text()') As typeActivite,
EXTRACTVALUE(Value(p), 'activites/zoneGeographiques[1]') As zoneGeographiques,
EXTRACTVALUE(Value(p), 'activites/zoneGeographiques[2]') As zoneGeographiques,
EXTRACTVALUE(Value(p), 'activites/zoneGeographiques[3]') As zoneGeographiques,
EXTRACTVALUE(Value(p), 'activites/zoneGeographiques[4]') As zoneGeographiques,
EXTRACTVALUE(Value(p), 'activites/zoneGeographiques[5]') As zoneGeographiques,
EXTRACTVALUE(Value(p), 'activites/zoneGeographiques[6]') As zoneGeographiques,
EXTRACTVALUE(Value(p), 'activites/zoneGeographiques[7]') As zoneGeographiques
FROM
artpiece x,
TABLE(XMLSEQUENCE(
EXTRACT(XMLTYPE(blob2clob(x.blob_piece)),'/instructionAC/activites')
))p
   where rf_pieg  = 'PIEG0034';

大家好，我發現我的問題的解決方案是否可以幫助某人：
