[14:25:26] short SPARQL https://w.wiki/4NmN having different than expected result. Please help. [14:36:03] when you use GROUP_CONCAT or other complex expressions in the SELECT, then you need to tell the label service explicitly which labels you want: https://w.wiki/4NmV [14:36:16] (see lines 14 and 15) [14:43:36] Thank's a lot. Now reading into it. [15:16:29] [Q] Anyone have any idea why this query doesn't return anything? I'm trying to list all continents whose English label start with "a" (case insensitive), but it returns nothing: https://w.wiki/4Nm$ [15:19:34] because ?aLabel doesn’t exist by the time you’re filtering on it [15:19:41] the label service only adds it at a very late stage in query execution [15:20:11] https://w.wiki/4Nn9 [15:33:07] Lucas_WMDE: Thanks!
