Only show filled attributes in leaflet popups (and not “null”-attributes)

问题 My leaflet map shows polygons from a GeoJSON file. This file has several attributes (attribute_1, attribute_2, etc.). However, some are filled with text and some are empty. How can I only show the attributes which are filled with text in my popup and not the empty ones? Using my code beneath every attribute is shown and if it's empty "null" is shown in the popup: // Integrate GeoJSON and style polygons $.getJSON("klimagutachten_2001.geojson",function(klimagutachten){ L.geoJson( klimagutachten

SQL Server parameterized query with a WHERE clause with Nulls

由 允我心安 提交于 2019-12-11 23:47:14
问题 VB.NET 2012, ADO.NET, SQL Server 2014 I setup a parameterized query that works well. I essentially read records from a DataTable that comes from a different source than my SQL Server. It's small enough that I elected to read record by record and build a query and hit the SQL Server for a match. However I am having trouble getting a match when one of my fields is supposed to be matched for a null. I know a record exist because I can look at it in SQL Server directly and see it. With my

DATE in sql and relation Algebra is NULL?

由 别等时光非礼了梦想. 提交于 2019-12-11 20:35:17
问题 I have a questions is it possible to set a date in tables NULL(in my case that a shipdate does not exist)? E.g I have this following tables: Customer{cid,name} Product{prodno,name} Order{orderid, shipdate, cid} Ordered{orderid, prodno, quantity} And now I wanto to get all Products which were never ordered. So I create this in RA(Relational Algebra): πP.name,P.prodno(σO.cid = C.cid AND Order.shipdate is NULL(Order)))⋈Customer) I am sure that it looks in SQL query: SELECT P.Name, P.Prodno FROM

问题 i know this question has been asked several times, but i think my problem differs a bit from the others: String resourcePath = "/Path/To/Resource.jar"; File newFile = new File(resourcePath); InputStream in1 = this.getClass().getResourceAsStream(resourcePath); InputStream in2 = this.getClass().getClassLoader().getResourceAsStream(resourcePath); The File-Object newFile is completely fine (the .jar file has been found and you can get its meta-data like newFile.length() etc) On the other hand the

问题 I'm developing a simple web service and client. See my snippet of service: @webService public Car carData(int id) { try { return carDAO.getCars(id); } catch (NullPointerException e) { System.out.println("Error: "+e.getLocalizedMessage()); } return null; } Is is ok to returning null to client, and then the client should take care of null OR is it better that web service take care of null and throws exception? UPDATE: How can I return nullpointerexception instead of returning null? What would
