나는 내가 XMLType을 변수에로드 XML 파일을 가지고 내가 다른 속성 값을 여러 .../ExtendedData/SchemaData/SimpleData 노드에서 다른 값을 추출 할 및 .../Polygon/outerBoundaryIs/LinearRing/coordinates 노드는이 테이블에 삽입하기 :XML에서 값을 추출하여 테이블에 삽입하려면 어떻게해야합니까?

CREATE TABLE LIE_GEOF 
(
IDE_GEO VARCHAR2(24) NOT NULL, 
COD_COM VARCHAR2(3) , 
COD_VIL VARCHAR2(5) , 
NOM_COM VARCHAR2(50) , 
ALT_MOY NUMBER(4,0) , 
SUP_HEC NUMBER(12,0) , 
NBR_POP NUMBER(10,0) , 
COD_ARR VARCHAR2(1) , 
COD_DEP VARCHAR2(2) , 
NOM_DEP VARCHAR2(30) , 
COD_REG VARCHAR2(2) NOT NULL, 
NOM_REG VARCHAR2(35) NOT NULL, 
TXT_POL CLOB , 
CONSTRAINT LIE_GEOF_PK PRIMARY KEY (IDE_GEO) USING INDEX 
);

삽입이 규칙을 따라야합니다 : 특정 속성 값으로 /Document/Folder/Placemark/ExtendedData/SchemaData/SimpleData 노드의

  • 값이 테이블의 11 개 첫째 필드로 이동합니다.
  • 노드 /Document/Folder/Placemark/Polygon/outerBoundaryIs/LinearRing/coordinates의 값은 테이블의 마지막 필드로 이동합니다 (TXT_POL, 이는 CLOB입니다).

예. 삽입 :

  • COMMUNE00000000000000001 COD_COM
  • 에
  • 216 ID_GEOFLA에 ...
  • 0.523147623541907,43.45799199978569 0.523016926446493,43.458214941462735을 ... TXT_POL

지금까지 시도한 것은 ID_GEOFLA과 일치하는 노드 값을 추출하는 것입니다. 하지만이 작동하지 않았다 :

CREATE OR REPLACE PROCEDURE load_xml (p_dir  IN VARCHAR2, 
            p_filename IN VARCHAR2) AS 
l_bfile BFILE := BFILENAME(p_dir, p_filename); 
l_clob CLOB; 
xml_data xmltype; 
ID_GEOFLA varchar2(255); 

BEGIN 

DBMS_LOB.createtemporary (l_clob, TRUE); 
DBMS_LOB.fileopen(l_bfile, DBMS_LOB.file_readonly); 
DBMS_LOB.loadfromfile(l_clob, l_bfile, DBMS_LOB.getlength(l_bfile)); 
DBMS_LOB.fileclose(l_bfile); 

xml_data :=XMLTYPE.createXML(l_clob); 

for x in (

select a.ID 
from 
    XMLTABLE('/Document/Folder/Placemark/ExtendedData/SchemaData' 
      PASSING xml_data 
      COLUMNS ID VARCHAR2(100) PATH '//SimpleData/text()' 

     ) a) loop 
     dbms_output.put_line(x.ID); 

     end loop; 

    DBMS_LOB.freetemporary (l_clob); 

    END; 
/

내 테이블에 XML 데이터를 가져올 수 있습니까?

XMLTable XPath를 참조해야하는 위치 표시가 여러 개 있습니다. 다음 열 경로는 어디 관련 속성을 지정하여 각 노드를 참조하십시오 :

    '/kml/Document/Folder/Placemark' 
    passing xmltype(l_clob)

    cod_com varchar2(3) path 'ExtendedData/SchemaData/SimpleData[@name="CODE_COM"]', 
    cod_vil varchar2(5) path 'ExtendedData/SchemaData/SimpleData[@name="INSEE_COM"]', 
    nom_com varchar2(50) path 'ExtendedData/SchemaData/SimpleData[@name="NOM_COM"]', 
    alt_moy number(4,0) path 'ExtendedData/SchemaData/SimpleData[@name="Z_MOYEN"]',

는 또한 /kml 루트 노드를 포함하고 기본 네임 스페이스의 선언을 확인할 수 있습니다.

감사합니다. Alex! 문제는 현재 내 실제 파일이 119 메가 바이트이고 스크립트가 3 시간 이상 실행되었으며 실제로 프로덕션 환경에서 사용하는 것이 현명하지 않다고 생각합니다. – ITE

아마도 데이터 양은 로드 및 구문 분석 자주? 삽입을하지 않고 루프에서 쿼리 부분을 실행할 수도 (어딘가 다른 곳에서), 우리가 XML에 얼마나 많은 시간을 소비했는지, 그리고 얼마나 많은 부분을 삽입했는지 확인할 수 있습니다. DBA는 병목 현상에 대해 조언 할 수 있습니다. 또 다른 옵션은 XML을 CSV로 분할 한 다음 외부 테이블 또는 SQL \ * Loader를 통해로드하는 것일 수 있습니다. 그러나 마지막 CLOB 열은 실제로 4k 이상일 수 있다고 가정하면 까다로울 수 있습니다. –
