Hi,
I am operating over the RDF_QUAD table directly and I find myself in

Is there any stored procedure I can use for this matter?
A quick glance at "sparql.sql" did not he
Pierre,
In order to access to SQL data via SPARQL you should create RDF Views
first, then query mapped data as if they're usual RDF quads. There's no
other way. Probably, we will never add an ability of calling SQL from
SPARQL because that will cause problems similar to inlining of assembler
fragm
OK, so it's possible to invoke SQL from SPARQL. Great.
But how to get the result back to SPARQL?
For example, I want to fetch the list of registered namespaces (SELECT *
from RDF_PREFIX).
How can I get this list back to a SPARQL endpoint? Thanks beforehand.

Well, I can give you a different exam
Hi,
It seems possible to call SQL from SPARQL as referenced in doc 'Calling SQL
from SPARQL' (§15.2.5).
Have you some examples? Is it possible to call statements
like backup_online('backup_#', 1); from a SPARQL endpoint?
Thanks beforehand. Your great support is really appreciated.
Pierre
