Hi Lorena,
Hi!
I'm trying this sample query, from
http://www.openlinksw.com/dataspace/dav/wiki/Main/VirtTipsAndTricksSPARQL11FeaturesExamplesCollection,
on my local Virtuoso Version: 06.01.3127.
SELECT MD5 ('test')
WHERE
{
?s ?p ?o
}
LIMIT 10
And I get the following error
Virtuoso 37000 Error SP030: SPARQL compiler, line 3: syntax error at
'MD5' before '('
SPARQL query:
define sql:big-data-const 0
#output-format:text/html
SELECT MD5 (?s)
WHERE
{
?s ?p ?o
}
LIMIT 10
Am I missing some prefix or is that this function is not supported on
Virtuoso Version: 06.01.3127 ?
It depends where you executed the query re. using prefix.
If it is from the SPARQL endpoint i.e. http://host:port/sparql then no
"sparql" infront, i.e.:
SELECT MD5 ('test') WHERE { ?s ?p ?o } LIMIT 10
If you executed it from iSQL tool or from Conductor (
http://host:port/conductor -> Database -> Interactive SQL ) then you should
use sparql placed infront of the query:
i.e.:
iSQL:
SQL > SPARQL SELECT MD5 ('test') WHERE { ?s ?p ?o } LIMIT 10
or from Conductor:
SPARQL SELECT MD5 ('test') WHERE { ?s ?p ?o } LIMIT 10
However I noticed your query from above is missing one white space after
('test').
What if you try the query like this: SELECT MD5 ('test') WHERE { ?s ?p ?o }
LIMIT 10
Please let us know if that worked for you.
Best Regards,
Rumi
thanks in advance
Lorena
