why can't you use a single INSERT query? An INSERT query allows a WHERE part

As mentioned in replies to your your previous mails, look at your data model as a graph, then convert it to triple patterns which make the SPARQL query.

Dear all,

In the given RDF model:
https://github.com/iliriani/Test/blob/main/Notebook.rdf

I am trying to find a way on how to insert with SPARQL a <weight>5</weight> node within an <Association> node 
where the <class1> is "Notebook" and <class2> is "Evaluation".
Same also, I want to add <weight>2</weight> in the <Association> where <class1> is "Student" and 
<class2> is "Evaluation" (<class1> and <class2> may be interchangeable) and so the process can continue for all 
classes.

The problem is:
1. How to specify exactly the <Association> where <class1> is "X" and <class2> is 
"Y", and
2. insert within the exact <Association> the node <weight> int </weight>

Since I am using Java I need the insert query for one insert then I can loop 
for all class1 and class2 and add weights.
Thanks a lot.
