Hi,

I know that it’s possible to do safe queries with Jena using a QuerySolution 
for both update queries and select queries.

Ex.

UpdateExecutionFactory

create<https://jena.apache.org/documentation/javadoc/arq/org/apache/jena/update/UpdateExecutionFactory.html#create-org.apache.jena.update.Update-org.apache.jena.query.Dataset-org.apache.jena.query.QuerySolution->(Update<https://jena.apache.org/documentation/javadoc/arq/org/apache/jena/update/Update.html>
 update, 
Dataset<https://jena.apache.org/documentation/javadoc/arq/org/apache/jena/query/Dataset.html>
 
dataset,QuerySolution<https://jena.apache.org/documentation/javadoc/arq/org/apache/jena/query/QuerySolution.html>
 inputBinding)

Is it possible to do something similar when running these queries against 
Fuseki over HTTP?

My scenario at the moment: Create a user with a username and email provided by 
the user. To be safe, for SQL, I would use a prepared statement. In Jena I 
would normally use a QuerySolution.
