wdt: 用于指代简单的三元组。要访问限定词，您需要使用前缀 p: 和 pq:。
在您的情况下，查询如下：
SELECT ?date ?place
WHERE {
wd:Q152316 p:P26 [
pq:P580 ?date;
pq:P2842 ?place
] .
}
查看此资源以深入了解这个主题。
额外信息：您可以在专门的项目中找到有关这个婚姻的更多数据（即 Q43890449，通过 P805 限定词可访问）。
因此，另一种查询如下：
SELECT ?date ?place
WHERE {
wd:Q152316 p:P26/pq:P805 ?marriage .
?marriage wdt:P585 ?date ;
wdt:P276 ?place .
}
英文:
wdt: is used for referring to simple triples. You need prefixes p: and pq: to access a qualifier.
In your case, the query is the following one:
SELECT ?date ?place
WHERE {
wd:Q152316 p:P26 [
pq:P580 ?date;
pq:P2842 ?place
] .
}
Take a look at this resource for deepening the topic.
Extra info: you can find more data about this marriage in a dedicated item (i.e., Q43890449, which is accessible through the P805 qualifier).
Hence an alternative query is the following one:
SELECT ?date ?place
WHERE {
wd:Q152316 p:P26/pq:P805 ?marriage .
?marriage wdt:P585 ?date ;
wdt:P276 ?place .
}
