derby正在引发代码为42802的异常。看来，这段特殊的代码是源代码的麻烦，但我不明白为什么。

if(!resultSet.next())
        {
            statement=connection.prepareStatement("CREATE TABLE "+TABLE_NAME+"("+
                    "ID varchar(100) primary key,\n"+
                    "TITLE varchar(100),\n"+
                    "AUTHOR varchar(100),\n"+
                    "ISBN varchar(100),\n"+
                    "PUBLISHER varchar(100),\n"+
                    "PUBLISHED_YEAR varchar(100))"
            );
        }
        else
        {
             statement = connection.prepareStatement(INSERT INTO BOOKS VALUES ('A', 'A', 'A', 'A', 'A', 'A'));
             statement.execute();
        }
