We're migrating from [tenforce/virtuoso](https://hub.docker.com/r/tenforce/virtuoso) to the official image [openlink/virtuoso-opensource-7](https://hub.docker.com/r/openlink/virtuoso-opensource-7/). With `tenforce/virtuoso` we used to run this query:

```sparql
DELETE FROM <http://languages-skos> { ?entity ?field ?value. } WHERE { ?entity ?field ?value . FILTER(str(?value) = "Multilingual Code") }
```

...against http://dba:dba@virtuoso:8890/sparql endpoint and worked well for years. 

Switching to `openlink/virtuoso-opensource-7` image, I'm getting:

```
Virtuoso RDF02 Error SR619: SPARUL DELETE access denied: database user 107 (SPARQL) has no write permission on graph http://languages-skos

SPARQL query:
define sql:big-data-const 0
DELETE FROM <http://languages-skos> { ?entity ?field ?value. } WHERE { ?entity ?field ?value . FILTER(str(?value) = "Multilingual Code") }
```

I've already ran `GRANT SPARQL_UPDATE TO "SPARQL";`

The legacy image Virtuoso version was:

```
$ virtuoso-t -v
Virtuoso Open Source Edition (Column Store) (multi threaded)
