Dao.update介绍

[英]Update all rows in the table according to the prepared statement parameter. To use this, the UpdateBuilder must have set-columns applied to it using the UpdateBuilder#updateColumnValue(String,Object) or UpdateBuilder#updateColumnExpression(String,String) methods.
[中]根据prepared statement参数更新表中的所有行。要使用此方法，UpdateBuilder必须使用UpdateBuilder#updateColumnValue（String，Object）或UpdateBuilder#updateColumnExpression（String，String）方法对其应用set列。

  6.     //先删除旧数据
  7.     DeleteBuilder<WeatherForecast, Long> forecastDeleteBuilder = forecastDaoOperation.deleteBuilder();
  8.     forecastDeleteBuilder.where().eq(WeatherForecast.CITY_ID_FIELD_NAME, weather.getCityId());
  9.     PreparedDelete<WeatherForecast> forecastPrepared = forecastDeleteBuilder.prepare();
  10.     forecastDaoOperation.delete(forecastPrepared);
  11.     //再插入新数据
  12.     for (WeatherForecast weatherForecast : weather.getWeatherForecasts()) {
  13.       forecastDaoOperation.create(weatherForecast);
