Hi all, I was hoping to make this to work with Fuseki 2.3.0:

PREFIX ex: <http://www.example.com/data#>
CONSTRUCT {
  ?id ex:has-name ?name; ex:has-surname ?mySurname
}
WHERE
{
  OPTIONAL { BIND ( ?surname AS ?mySurname ).  FILTER ( ?surname != '' ) }
  #BIND ( ?surname AS ?mySurname )

  VALUES (?id ?name ?surname)
  {
    ( ex:1 "John" "Smith" )
    ( ex:2 "Zak" "Mc Kracken" )
    ( ex:3 "Ben" "" )
    ( ex:4 "Alice" "Wonderland" )
    ( ex:5 "Mickey" "" )
  }
}
i.e., I've a list of rows to build some RDF from, where certain field values are empty or should be ignored. The result should produce triples with name+surname, when surname is valid, only name, when it is invalid. I always get back triples with name only, even when I use the non-optional binding. So, how can I get this result, when using VALUES?

The longer story is that the problem have arisen from tests I was doing with the very nice tool TARQL (https://github.com/tarql/tarql, https://github.com/tarql/tarql/issues/55)

Thanks in advance,
Marco
