Probably one old_subj / old_rel / old_obj isn't the right format. e.g
if old_obj is a string, is it quoted correctly? Does it contain a " and
need escaping?
Printout 'query' to check it got assembled as expected.

The parser expected more characters.

Hello,
If you could please help with the following. I am running a DELETE query, which
works through the Apache Jena Fuseki interface fine:
PREFIX dbo:<http://dbpedia.org/ontology/>
PREFIX rdf:<http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX asc:<http://asc.com/ontology/ <http://audiosinc.com/ontology/>>
DELETE DATA
{dbo:wikiPageID:13311 rdf:label asc:Entity:Content}
But when I run it through the Python SPARQLWrapper as follows:
query = '''PREFIX dbo:<http://dbpedia.org/ontology/>
PREFIX rdf:<http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX asc:<http://asc.com/ontology/ <http://audiosinc.com/ontology/>>
That's mangled. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
DELETE DATA
{ ''' + old_subj + " " + old_rel + " " + old_obj + " }"
I get an error. I tried different variants of the above, but all of them give
errors. This particular one gives the following error:
[2020-07-10 11:37:04] Fuseki INFO [81] 400 Encountered "<EOF>" at line 5,
column 86.
Was expecting one of:
"graph" ...
"}" ...
";" ...
"," ...
"." ...
Thanks,
