Hi Hugh,
Why the expected result contains *three* triples of <suject> <predicate>
string ?
SQL> sparql select * from <teste_datatype> where {?s ?p ?o};
> s
> p
> o
> VARCHAR

Taking into consideration, the SPARQL 1.0 spec, I would expected just
*one*triple <suject> <predicate> string.
----------
11.4.7 datatype
IRI datatype (typed literal typedLit)
IRI datatype (simple literal simpleLit)
Returns the datatype IRI of typedLit; returns *xsd:string *if the parameter
is a *simple literal.*
----------
Best Regards,
Percy
