Hi,
I got the following problem. If I use the search field of the main page
searching for "Brian O'Nolan" I get a result.
But if I use the following piece of code in the query service no result
shows up.
SELECT ?_Geburtsdatum WHERE {
?s ?label "Brian O'Nolan".
OPTIONAL { ?s wdt:P569 ?_Geburtsdatum. }
}
What I'm doing wrong? Is it a problem of coding the apostrophe?
If yes, how do I have to code it?
Best regards
Detlef
