给定一个 Weather 表，编写一个 SQL 查询，来查找与之前（昨天的）日期相比温度更高的所有日期的 Id。 +---------+------------------+------------------+ | Id(INT) | RecordDate(DATE) | Temperature(INT) | +---------+------------------+------------------+ | 1 | 2015-01-01 | 10 | | 2 | 2015-01-02 | 25 | | 3 | 2015-01-03 | 20 | | 4 | 2015-01-04 | 30 | +---------+------------------+------------------+ 例如，根据上述给定的 Weather 表格，返回如下 Id: +----+ | Id | +----+ | 2 | | 4 | +----+ 来源：力扣（LeetCode） 子查询 SELECT Id FROM Weather as a where Temperature > (select Temperature from Weather as w where DATEDIFF(a.RecordDate, w.RecordDate) = 1 AND a.Temperature > w

I need to display the location and city name when a user enters a ZIP Code. How do I get the corresponding location names? I would use a website like http://www.zipinfo.com/search/zipcode.htm and just send the zipcode to that, retrieve the input, parse for the city name, easy as that. Try the USPS zipcode API - http://www.usps.com/webtools/welcome.htm You can use the PlaceFinder geocoding web service to make REST based requests using the postal code you want to resolve to a name. The service supports both XML and JSON response formats . Here is a listing of the response elements returned by

I have questions on the behavior I am seeing with applying Kalman Filter (KF) to the following forecast problem. I have included a simple code sample. Goal: I would like to know if KF is suitable for improving forecast/simulation result for a day ahead (at t+24 hours), using the measurement result obtained now (at t). The goal is to get the forecast as close to measurement as possible Assumption: We assume the measurement is perfect (ie. if we can get the forecast matches the measurement perfectly, we are happy). We have a single measurement variable (z, real wind speed), and a single

What I have: Latitude and Longitude. What I want: Get weather update for these coordinates. If you want to use the Google Weather API, you'll have to pass it either a City, State or a Zip code. To do this, you'll need to GeoCode your lat/long to get this info. Here's the URL to the Google Weather API: http://www.google.com/ig/api?weather=Seattle,WA Here's a sample code to take lat/long and convert to zip: Geocoder geocoder = new Geocoder(this, Locale.ENGLISH); List<Address> addresses = null; try { addresses = geocoder.getFromLocation(latitude, longitude, 3); } catch (IOException ex) { //Handle

I'd like to know if the AccuWeather API is free for commercial use. If not, how I can use it for commercial purposes? Is there a totally free weather API that I can use for my app? mattexx Accuweather data is not free. They will quote you for a custom service if you call their sales support. At one of my previous companies (circa 2007), we were able to get a contract with them for national hourly weather across their station network very cheap, but still not free. If you are looking for free weather APIs, Please have a look at weather underground . sakher I have looked in many weather data

To give a little background, we have an application which stays open in the browser and updates some information on the map every few minutes. We let the users open the weather layer on the map, but the weather only loads once, when the layer is created. After a while, it gets outdated and we'd like it to stay current. I've tried everything from recreating the layer and setting the map to null, then back to the current map, but temperatures never

Something of the form import akka.stream.OverflowStrategy.fail import akka.stream.scaladsl.Source case class Weather(zip : String, temp : Double, raining : Boolean) val weatherSource = Source.actorRef[Weather](Int.MaxValue, fail) val sunnySource = weatherSource.filter(!_.raining) ... My question is: how do I send data to my ActorRef based Source object ? I assumed sending messages to the Source was something of the form //does not compile
