Ah, your query works!
I had just missed a '}' character in the end.
Thanks Andy, but why did my query not work. It was:
SELECT ?subject ?predicate ?object
WHERE {
?subject ?predicate ?object
}
LIMIT 25
Please note that I can't see your screen so I can't see what the output
to the general query was.
But I guess it has the G column set. Named graph not default graph.

The list does not pass attachments through.
How are you runnign the server exactly?
Ask this query:
SELECT * { { ?s ?p ?o } UNION { GRAPH ?g {?s ?p ?o } } }
and don't forget to press the "query" button (it caches results otherwise).

Andy,
I used a simple ulo.ttl file (owl file converted to ttl format) to
upload on dataset /ds (Fuseki 2.4.0) and ran a simple query to get all
triples. The file uploaded correctly but generated no result in query
results portion of the Fuseki v2.4.0 web UI, although there are 11
triples in ulo.ttl
The ttl file is attached. There was no result from the execution of query, nor
a message of success/failure.
Please can you suggest something so that I could get some output from the query?
Regards
Mahmood

Note what it says at the top of the page:
"""
This page covers Fuseki v1. As of Jena 2.13.0, there is also a new
version, Fuseki v2. See Fuseki2 documentation. Both Fuseki v1 and
Fuseki
v2 are currently active and maintained.
"""
You are looking at Fuseki1 documentation.

It is looking for a file called tdb.ttl which is not found.
--desc is for a assembler file - you have to provide that, the
documentation is out of date.
If all you eant is some small data for experimentation:
fuseki-server --file <YourData.ttl> /ds
will work
If you have a TDB database,
fuseki-server --loc <YourDB> /ds

Hi,
[I am using Apache Jena Fuseki 2.4.0 on a Windows 10 machine]
Can anyone please point me to the tdb.ttl for running a few practice
SPARQL queries? The Apache Jena says that TDB is a part of Apache
Jena
3.1.0 on the following page:
http://jena.apache.org/documentation/tdb/index.html
I have installed Fuseki 2.4.0 and I am looking to run the Fuseki
Server with tdb.ttl using the command:
fuseki-server --desc tdb.ttl /ds
as given on the page:
https://jena.apache.org/documentation/serving_data/
The error I get is as follows:
