RDF triples Storage in VOS

Hi,
I used the function Quad Store Upload from the conductor (version 07.20.3229) to upload some triples (turtle file). The upload is done and when I query data with SPARQL, I found them. However, when I query the RDF_QUAD I cannot find the triples. The number of rows in this table is the same as before the import.
My question: where the data is stored?

Thanks.

Why are you querying the RDF_QUAD table directly, as this is generally not recommended ?

What is the SPARQL query that is running successfully compared to the query against the RDF_QUAD table that does not return results ?

Thank you it was resolved.
