SPARQL查询出错

Question

我的SPARQL查询出错但无法找到它：

询问

PREFIX owl: <http://www.w3.org/2002/07/owl#> 
PREFIX xsd: <http://www.w3.org/2001/XMLSchema#>

SELECT DISTINCT ?lat, ?long { 
:Taj_Mahal dbpedia2:latitude ?lat . 
:Taj_Mahal dbpedia2:longitude ?long }

错误

Encountered " "," ", "" at line 9, column 21.
Was expecting one of:
     ...
     ...
    "from" ...
    "where" ...
    "(" ...
    "{" ...

有什么建议??

Answer 1

你不应该在?lat和?long之间加一个逗号

SELECT DISTINCT ?lat ?long { 
    :Taj_Mahal dbpedia2:latitude ?lat . 
    :Taj_Mahal dbpedia2:longitude ?long 
}

run query
