从列中提取 xml 值并将它们插入另一个数据库

Question

我有一个包含 XML 文件的 Blob 列的数据库。 我想在这个数据库中检索存储在 Blob 中的 XML 标记的值，以便在另一个数据库中的各自列中详细说明它们。

那么，我如何获取x 标签的值（如下面的 SQL 查询所示）并将其插入到我的另一个数据库的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[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，如果可以帮助某人，我找到了解决问题的方法：

> ** creation of new table
------------------------
create table TestSipac(
  categorieProjet          varchar2(100),
  coutParBeneficiaire      varchar2(100),
  etat                     varchar2(100),
