从列中提取xml值并将其插入到另一个数据库中

Question

我有一个数据库，其中的Blob列包含XML文件。 我想在此数据库中检索存储在Blob中的XML标签的值，以在另一个数据库的它们各自的列中详细说明它们。

因此，如何获取x标记的值（ 如下面的SQL查询所示 ）并将其插入到其他数据库的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[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，我发现我的问题的解决方案是否可以帮助某人：
