SPARQL Parse Error: unexpected terminal

Question

I've been using gruff to create and execute some simple SPARQL queries, but have run into some trouble. The following query works (prefixes have been left out):

SELECT ?k
WHERE
{ ?k  rdf:type  uw:pcservice . }

However, when I introduce the COUNT function, as seen below, I get the following error in gruff:

Error: Parse error: unexpected terminal ( (value: :|(|). Expected terminals: (* varname reduced distinct). [condition type: sparql-parse-error-unexpected-terminal]

SELECT (COUNT(?k) AS ?count)
WHERE
{ ?k  rdf:type  uw:pcservice . }

Not sure what is causing this. Any clues would be appreciated. Thanks.

Answer 1

Given the error it sounds like this tool doesn't support SPARQL 1.1. It's expecting a vanilla SELECT [*|varname|reduced|distinct], excluding aggregates and assignment.
