Hi Jindřich,
Can you please provide a test case (data & query) to demonstrate the issue ?

Hello Jindřich,
how do you apply both FILTERs? Obviously the filter on the length needs
to be evaluated first, and I'm wondering how this would be evaluated if
somebody uses FILTER(cond1 && cond2) as && should be commutative.
Does it work if you use a sub-SELECT to filter by length first?

Unfortunately, using STRDT(?literal, xsd:string) doesn't make difference
and the error is still thrown. ?literal is already a string.

I've had similar problems lately working with strings.
SPARQL snippets unctions that worked on other products and produced this
kind of errors in Virtuoso.
Try using:
STRDT(?literal, xsd:string)
as input to the substr() function,
and it should work.

Hi,
I have a query that first filters literals of given length:
FILTER (STRLEN(?literal) = 8)
And then it extracts a substring via SUBSTR():
SUBSTR(?literal, 8, 1)
However, Virtuoso throws Virtuoso 22011 Error SR026: SPARQL substr: Bad
string subrange: from=8, len=1.
How is that possible?
