HarmonyOS 如何在for循环中调用await

可通过async/await语法实现，参考示例：

async queryData(){
  {
    if (this.rdbStore == null) {
      console.error(Create Store1.db failed! store1 is null);
      return;
    }
  }
  try {
    let predicates: relationalStore.RdbPredicates = new relationalStore.RdbPredicates(“EMPLOYEE”);
    let resultSet = await this.rdbStore.query(predicates); // 查询所有数据
    console.info(Query data successfully! row count:${resultSet.rowCount});
    while (resultSet.goToNextRow()) {
      const id = resultSet.getLong(resultSet.getColumnIndex(“ID”));
      const name = resultSet.getString(resultSet.getColumnIndex(“NAME”));
      const age = resultSet.getLong(resultSet.getColumnIndex(“AGE”));
      const salary = resultSet.getDouble(resultSet.getColumnIndex(“SALARY”));
      console.info(id=${id}, name=${name}, age=${age}, salary=${salary});
      const tmp = new ItemBean(name, age.toString(), salary.toString());
      this.dbSet.push(tmp);
    }
    resultSet.close();
  } catch (err) {
    console.error(Query data failed! err code:${err.code}, err message:${err.message})
  }
}
