[Virtuoso-users] regex flags

[Sergio Fernández]

Hi,

I've a triple like:

<#bar> rdfs:label "Bar"

Obviously this query will return results:

SELECT DISTINCT ?uri
WHERE {
  ?uri rdfs:label ?label . 
  FILTER REGEX(?label, "Bar")
}

But according the specification [1] I also expected to get result with
this one:

SELECT DISTINCT ?uri
WHERE {
  ?uri rdfs:label ?label . 
  FILTER REGEX(?label, "bar", "i")
}

But the latest query doesn't return any tuple. Is there any better way
to do this string comparisons? I remember that there also exists a
built-in function to compare strings in Virtuoso instead regex, but now
I don't remember its name/reference...

Cheers,
