Exception | Condition |

SparqlUpdateException | Thrown if an error occurs in making the update. |
This method will first attempt to parse the update into a SparqlUpdateCommandSet object. If this succeeds then each command in the command set will be issued to Virtuoso.
If the parsing fails then the update will be executed anyway using Virtuoso's SPASQL (SPARQL + SQL) syntax. Parsing can fail because Virtuoso supports various SPARQL extensions which the library does not support and primarily supports SPARUL updates (the precusor to SPARQL 1.1 Update).
