thanks Hugh for your prompt reply
this query results in an error SP031: SPARQL compiler: Function name
"bif:normalize-space" contains invalid characters; this may be an
attempt of bypassing security restrictions
prefix rdfh: <http://lod2.eu/schemas/rdfh#>
SELECT bif:normalize-space(?s_city)
FROM <http://lod2.eu/schemas/rdfh-inst#ssb1_ttl_qb>
WHERE{
?supplier a rdfh:supplier.
?supplier rdfh:s_city ?s_city.
}
and this one also gives an error
prefix rdfh: <http://lod2.eu/schemas/rdfh#>
SELECT bif:contains(?s_city, '4')
FROM <http://lod2.eu/schemas/rdfh-inst#ssb1_ttl_qb>
WHERE{
?supplier a rdfh:supplier.
?supplier rdfh:s_city ?s_city.
}
Virtuoso 22023 Error SR468: contains() can not be called as plain built-in
function, it's a macro handled by SQL compiler
Maybe the bif: prefix is badly defined?

Hi Lorena,
What is the actual query you are executing using the “bif:” prefix
that is resulting in the "SP031: SPARQL compiler: Function name
"bif:normalize-space" contains invalid characters; this may be an
attempt of bypassing security restrictions” error ?
Best Regards

Hi
I'd like to use this function
http://www.w3.org/TR/xpath-functions/#func-normalize-space in a SPARQL
query in Virtuoso 7.
Is it available?
If I declare the prefix fn as
prefix fn: <http://www.w3.org/2005/xpath-functions>
and then use the function as
fn:normalize-space(str(?s))
I retrieve the following error
Virtuoso 42001 Error SR185: Undefined procedure
DB.DBA.http://www.w3.org/2005/xpath-functionsnormalize-space.
I've also found a function with the same name and behavior in Virtuoso
documentation
(http://docs.openlinksw.com/virtuoso/xpf_normalize_space.html).
Is it possible to use this function in a SPARQL query?
I've tried to use it with the prefix bif, but I also get an error
Virtuoso 37000 Error SP031: SPARQL compiler: Function name
"bif:normalize-space" contains invalid characters; this may be an
attempt of bypassing security restrictions
best regards,
Lorena
