Trying to perform federated SPARQL queries on OpenLink Virtuoso but throwing error

Question

I am trying to perform federated searches using my locally installed Virtuoso (7.2.2.). I try to use the following 2 commands :

 grant select on "DB.DBA.SPARQL_SINV_2" to “SPARQL”;

 grant execute on "DB.DBA.SPARQL_SINV_IMP" to "SPARQL”;

but I get the following error:

Error 42000: [Virtuoso Driver][Virtuoso Server]SR137: Bad user name in GRANT/REVOKE.

Any suggestions on tackling this error?

Answer 1

I believe @Joshua Taylor got it mostly right in the comments.

Try copying and pasting these --

GRANT SELECT ON "DB"."DBA"."SPARQL_SINV_2" TO "SPARQL";

GRANT EXECUTE ON "DB"."DBA"."SPARQL_SINV_IMP" TO "SPARQL";

Virtuoso-specific assistance often comes faster through the Virtuoso Users mailing list , the public OpenLink Support forums , or a confidential OpenLink Support Case . ObDisclaimer: I work for OpenLink Software , makers of Virtuoso .
