TASK DESCRIPTION
#Law & Order episodes
# All Law & Order episodes on Wikidata.
# According to enwp, “[a] total of 456 original episodes… aired before
cancellation” (https://en.wikipedia.org/wiki/List_of_Law_%26_Order_episodes).
# As of this writing, the query returns 451 results, so some episodes are
missing (either without item or lacking the necessary statements to match this
query).
SELECT (SAMPLE(?seasonNumber) AS ?seasonNumber) (SAMPLE(?episodeNumber) AS
?episodeNumber) (SAMPLE(?title) AS ?title) (MIN(?pubDate) AS ?pubDate) ?episode
{
# All episodes should be instance of episode with series Law & Order.
?episode wdt:P31 wd:Q21191270;
wdt:P179 wd:Q321423.
# Many of them also have the season as series, so we can get episode and
season number from qualifiers there.
OPTIONAL {
?episode p:P179 [
# the season also has series Law & Order
ps:P179/p:P179 [
ps:P179 wd:Q321423;
pq:P1545 ?seasonNumber
] ;
pq:P1545 ?episodeNumber
]
}
OPTIONAL { ?episode wdt:P1476 ?title. }
OPTIONAL { ?episode wdt:P577 ?pubDate. }
}
GROUP BY ?episode # make sure we return each episode only once – a few have
multiple publication dates, for example
ORDER BY IF(BOUND(?seasonNumber), xsd:integer(?seasonNumber), 1000)
xsd:integer(?episodeNumber) ?title
