Hi

I have a sparql query a filter on the length of labels. In fact i want to
select just label with length less than 256.

FILTER(regex(str(?label), "^.{1,256}$") )

this filter works properly in the vistuoso conductor, but i have to run my
query on ISQL, in isql an error returns which related to the $ or ".
#error:sq074

Can you please let me know your suggestion for solving that?

Thanks

Best Regards
