Dear Hugh,
Thanks a lot for the help. I tried to profile using profile but I am
getting the following errors:
SQL> profile('sparql select ?a?b?c where{?a ?b ?c}');
*** Error 42001: [Virtuoso Driver][Virtuoso Server]SR185: Undefined
procedure DB.DBA.profile.
at line 9 of Top-Level:
profile('sparql select ?a?b?c where{?a ?b ?c}')
SQL> sparql profile('select ?a?b?c where{?a ?b ?c}');
*** Error 37000: [Virtuoso Driver][Virtuoso Server]SQ074: Line 1: SP030:
SPARQL compiler, line 1: syntax error at 'profile' before '('
at line 10 of Top-Level:
sparql profile('select ?a?b?c where{?a ?b ?c}')
