Error in SPARQL Query

问题:

I'm getting an error with my SPARQL query but can't find it out:

Query

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

Error

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

Any suggestion??

回答1:

you should not put a comma between ?lat and ?long

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

run query
