엑셀 시트에서 데이터베이스로 데이터를 업로드해야합니다."java.sql.SQLException : setObject, Exception = 입력 문자열 :"Pr ""

이 기능을 구현하기 위해 Apache POI 개념을 사용했습니다.

엑셀 시트의 데이터를 직원 데이터 배열 목록에로드합니다.

호출 가능한 명령문을 통해 데이터를 전달하기 위해 sqlData를 구현하는 EmployeeObj가 작성되는 Java 클래스가 하나 있습니다.

PL/SQL에서 EmployeeData 생성 유형은 다음과 같습니다

create or replace type EMP_OBJ_DT_ARR as table of EMP_DATA_OBJ; 

    create or replace TYPE EMP_DATA_OBJ AS OBJECT 
    (
    EMP_NO   VARCHAR2(10), 
    EMP_ID   NUMBER,  
    LAST_NM  VARCHAR2(100), 
    FIRST_NM  VARCHAR2(100), 
    DOJ   VARCHAR2(100),   
    GENDER   VARCHAR2(50), 
    STATUS   VARCHAR2(100), 
    REPORTING_MGR NUMBER,   
    LEVEL_2_MGR  NUMBER,   
    EMAIL_ID  VARCHAR2(200), 
    STREAM_ID  VARCHAR2(100),  
    DESIGN_ID  VARCHAR2(100), 
    EMP_LOCATION VARCHAR2(100), 
    GEO_CODE  VARCHAR2(100), 
    TENTATIVE_LAST_DAY CHAR(8));

숫자 인 데이터베이스 필드에 숫자가 아닌 문자열을 채우려 고 시도합니다. 너는 그렇게 할 수 없다. –

First_nm은 varchar2 필드입니다. – 5extremers

그리고'pstmt.registerOutParameter (1, Types.BIGINT);는 의도 된 것입니까? –

저는 왜 numberFormatException이 발생하는지 거의 이해하지 못했습니다.

저는 SqlData를 구현하는 java 클래스를 개발했습니다.

readSQL(SQLInput stream, String typeName) 
writeSQL(SQLOutput stream)

여기 writeSQL가 스트림으로서 데이터를 취할 것이다

SQLDATA 클래스에서 구현 될 필요가있는 2 가지 방법이있다. 그래서 내가 무엇을 건지면, 그것은 물결에 덧붙여 질 것이다. 내가 자바

id  name age 
    1  xyz 26

으로 데이터 유형을 데이터를 전달하고 가정합니다

PL/SQL 데이터 형식에서

id - Integer 
    name - String 
    age - Integer

는

id -number 
name -varchar2 
age -number

내가 순서대로 데이터를 검색하려고 할 경우 이름, 아이디 및 나이 (예 : xyz 1 26) 다음 그것은 sqlException을 사용하여 numberFormatException을 던집니다. 그래서 우리가 가지고있는 것과 같은 순서로 전달해야합니다.
