SELECT DESCRIPTION,DETAILED_DESCRIPTION,PRIORITY,RISK_LEVE FROM Table_Name

该DETAILED_DESCRIPTION列具有值CLOB

下面是用于获取数据的代码:但是我在读取"DETAILED_DESCRIPTION"字段时收到错误"错误:读取错误"

Statement statement;

ResultSet resultSet;

oracleCon.setAutoCommit(false);

statement = oracleCon.createStatement();

String chdet[] = new String[8];
String query="SELECT DESCRIPTION,DETAILED_DESCRIPTION,PRIORITY,RISK_LEVEL FROM Table_Name"; 

                    resultSet = statement.executeQuery(query);
                    ArrayList<String> record=new ArrayList<String>();               

                    while (resultSet.next())
                    {
                    record.add(resultSet.getString("DESCRIPTION"));                 
                    record.add(resultSet.getString("DETAILED_DESCRIPTION"));
                    record.add(resultSet.getString("PRIORITY"));
                    record.add(resultSet.getString("RISK_LEVEL"));              
                    }                   
                    if(record.size()>0)             
                    {
                        chdet[0] = record.get(0);
                        chdet[1] = record.get(1);
                        chdet[2] = record.get(2);
                        chdet[3] = record.get(3);
                        break;                          
                    }                               
                }
            return chdet;
