xmltype.getClobVal : ORA-06502 : PL/SQL : 숫자 또는 값 오류

Question

내 목표는 Oracle 10g를 통해 XML 파일을 작성하는 것입니다.이를 위해 dbms_xmldom 라이브러리를 사용합니다.

감사 : 나는 getClobVal 기능을 통해 XMLType을에서 만든 CLOB를 검색 할 때 , 서버는 ORA-06502: PL/SQL: numeric or value error.

내 프로그램을 표시합니다.

Answer 1

l_xmltype.getClobVal ()

프로그래밍, 당신은 무료로 명시해야합니다)와 같은 임시 CLOB 값을 getClobVal을 (호출하면

이 완료 될 때 (I이 충분히 될 것이라고 확신하지 않는다) 그것. PL/SQL 메소드 DBMS_LOB.freeTemporary()를 호출하여이 작업을 수행 할 수 있습니다.
