查询数据返回结果集内没有值

[望仔737]

在鸿蒙OS中，我想基于Stage模型，利用关系型数据库的基础代码 与本地的SQLite数据库相连，但是数据库连接没有问题 查询时结果集没有值，球球各位大佬解惑，可能问题很简单 ，我会女里成长的！！

  query(device_id: string, callback: Function, isAll: boolean = true) {
    let predicates = new data_rdb.RdbPredicates(CommonConstants.TH_STATE_TABLE.tableName);
    if (!isAll) {
      predicates.equalTo('device_id', device_id);
    }
    this.th_state.query(predicates, function (resultSet) {
      let count = resultSet.rowCount;
      if (count === 0 || typeof count === 'string') {
        console.log(`${CommonConstants.TABLE_TAG}` + 'Query no results!');
        callback([]);
      } else {
        resultSet.goToFirstRow();
        const result = [];
        for (let i = 0; i < count; i++) {
          let tmp: th_state = { _id: 0, device_id: '', SW: '', state: '', time: '' };
          tmp._id = resultSet.getDouble(resultSet.getColumnIndex('_id'));
          tmp.device_id = resultSet.getString(resultSet.getColumnIndex('device_id'));
          tmp.SW = resultSet.getString(resultSet.getColumnIndex('SW'));
          tmp.state = resultSet.getString(resultSet.getColumnIndex('state'));
          tmp.time = resultSet.getString(resultSet.getColumnIndex('time'));
          result[i] = tmp;
          resultSet.goToNextRow();
        }
        console.log("111111f");
        callback(result);
      }
    });
  }

报错结果是这样：
