Regression in Stardog 3.1.4 with SPARQL UPDATE + WITH and USING keywords

[bouffard....@ireq.ca]

Here is a minimal working example that worked as expected in Stardog 2.2.3 but does not work anymore in Stardog 3.1.4:

* Create a new DB with the following quad:

<http://1> <http://1> <http://1> <http://1>.

* The following query should insert a quad but does not in Stardog 3.1.4:

with <http://1>
insert
{
  <http://2> <http://2> <http://2>
}
using <http://1>
where
{
  <http://1> <http://1> <http://1>
}

Thanks,
Alexandre

As far as I can tell, this is caused by incorrect scoping of the BGP when it's parsed [1].

We created issue #2489 for this and we'll fix this in an upcoming release.

As a workaround, if you use `using named` instead, you'll get the expected result.  I realize that alters the intent of the query, but depending on your use case, it may work out.

Cheers,

Mike
