我在这个例外上经历了很多帖子，但没有得到任何明确的想法。

我开发了一个应用程序，它从excelsheet中获取数据并将其插入数据库。

为实现这一目标，我使用了POI Apache概念。 我已经从excelsheet（HSSFCell）对象获取数据到Object []。 我开发了实现SQLdata和Serializable的类。

public class EmployeeObj implements SQLData,Serializable {
public long EMP_ID;               
public String FIRST_NM;    
public String MIDDLE_NM; 
public String DOJ;          
public String GENDER;   
public String STATUS;   
public long REPORTING_MGR;     
public String LAST_NM;
public String EMAIL_ID;
public String STREAM_ID;   
public String DESIGN_ID;   
public String EMP_LOCATION; 
public String GEO_CODE;   
public String EMP_NO; 
public long LEVEL_2_MGR;  
public String TENTATIVE_LAST_DAY;
private String sql_type="EMP_DATA_OBJ";
static int count=0;
public EmployeeObj() {
    super();
}
public EmployeeObj(String sql_type,Object[] empObj)
{
    this.sql_type = sql_type;
    count=count+1;
    this.EMP_ID=Long.parseLong(empObj[0].toString());               
    this.FIRST_NM=empObj[1].toString();    
    this.MIDDLE_NM=empObj[2].toString(); 
    this.DOJ=empObj[3].toString();          
    this.GENDER=empObj[4].toString();   
    this.STATUS=empObj[5].toString();   
    this.REPORTING_MGR=Long.parseLong(empObj[6].toString());     
    this.LAST_NM=empObj[7].toString();
    this.EMAIL_ID=empObj[8].toString();
    this.STREAM_ID=empObj[9].toString();   
    this.DESIGN_ID=empObj[10].toString();   
    this.EMP_LOCATION=empObj[11].toString(); 
    this.GEO_CODE=empObj[12].toString();   
    this.EMP_NO=empObj[13].toString(); 
    this.LEVEL_2_MGR=Long.parseLong(empObj[14].toString());  
    this.TENTATIVE_LAST_DAY=empObj[15].toString();
}

@Override
public String getSQLTypeName() throws SQLException {
    // TODO Implement this method
    return sql_type;
}

@Override
public void readSQL(SQLInput stream, String typeName) throws SQLException {
    // TODO Implement this method
    sql_type=typeName;
    this.EMP_ID=stream.readLong();               
    this.FIRST_NM=stream.readString();    
    this.MIDDLE_NM=stream.readString();
    this.DOJ=stream.readString();  
    this.GENDER=stream.readString();  
    this.STATUS=stream.readString();   
    this.REPORTING_MGR=stream.readLong();       
    this.LAST_NM=stream.readString();
    this.EMAIL_ID=stream.readString();
    this.STREAM_ID=stream.readString();
    this.DESIGN_ID=stream.readString();  
    this.EMP_LOCATION=stream.readString();
    this.GEO_CODE=stream.readString();
    this.EMP_NO=stream.readString();
    this.LEVEL_2_MGR=stream.readLong();    
    this.TENTATIVE_LAST_DAY=stream.readString();
    }


@Override
public void writeSQL(SQLOutput stream) throws SQLException {
    // TODO Implement this method
    stream.writeLong(EMP_ID);
    stream.writeString(FIRST_NM);
    stream.writeString(MIDDLE_NM);
    stream.writeString(DOJ);
    stream.writeString(GENDER);
    stream.writeString(STATUS);
    stream.writeString(LAST_NM);
    stream.writeString(EMAIL_ID);
    stream.writeString(STREAM_ID);
    stream.writeString(DESIGN_ID);
    stream.writeString(EMP_LOCATION);
    stream.writeString(GEO_CODE);
    stream.writeString(EMP_NO);
    stream.writeString(TENTATIVE_LAST_DAY);
    stream.writeLong(REPORTING_MGR);
    stream.writeLong(LEVEL_2_MGR);
}
}

我创建了一个可调用的语句对象来从java调用pl / sql过程。

       CallableStatement pstmt =
           getDBTransaction().createCallableStatement("begin ?:= employee_dml.Main(?,EMP_OBJ_DT_ARR(?),?) end;",
                                                      0);
       EmployeeObj eob=null;
       Object[] obj = EmployeeD.toArray(new Object[EmployeeD.size()]);
       for(int i=0;i<EmployeeD.size();i++)
       {
           obj[i]=EmployeeD.get(i).toString();
       }
       eob=new EmployeeObj("EMP_DATA_OBJ",obj);
       pstmt.setInt(1,row_id);
       pstmt.setObject(2, (Object) eob);
       pstmt.setString(3,user);
       pstmt.registerOutParameter(1, Types.BIGINT);

       try
       {
       pstmt.executeUpdate();
       }
       catch(SQLException e1)
       {
               e1.printStackTrace();
           }
       dbTransaction.commit();

pl / sql程序是：

  END INSERT_EMPDATA;
  END employee_dml;

运行代码后，我会得到

   java.sql.SQLException: Missing IN or OUT parameter at index:: 4

我只传递了3个参数和1个结果参数。所以我无法理解为什么它要求索引4的参数。请建议我。

1 个答案:

答案 0 :(得分：1)

函数的输出参数位于索引1.输入参数从索引2开始直到4。

eob=new EmployeeObj("EMP_DATA_OBJ",obj);
pstmt.registerOutParameter(1, Types.BIGINT);
pstmt.setInt(2,row_id);
pstmt.setObject(3, (Object) eob)
pstmt.setString(4,user);
