Jump to navigation Jump to search

This page is parsed by the web interface of the query service to fill the query example dialog. Many of the examples also work in {{Wikidata list}} template calls parsed by the ListeriaBot, which however requires the ?item field variable to be selected.

Consider adding a comment in the query noting what it illustrates, when and by whom it was written and which are its limitations given the current data and use of properties at Wikidata.

Some queries did not fit here because of technical restrictions:

Simple queries

These basic queries help to understand SPARQL and the Wikibase RDF format.

Cats

This query looks at all items whose value of instance of (P31) is house cat (Q146). It uses the service wikibase:label to return the labels in your default language or in English.

SELECT ?item ?itemLabel
WHERE
{
  ?item wdt:P31 wd:Q146. # Must be a cat
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],mul,en". } # Helps get the label in your language, if not, then default for all languages, then en language
}
Try it!

Horses (showing some info about them)

This query looks at items whose value of instance of (P31) is horse (Q726) or any subclass of (subclass of (P279)) horse (Q726). It displays the value of mother (P25), father (P22), and sex or gender (P21) and computes the birth year using date of birth (P569) and the death year using date of death (P570). Items are ordered using the horses' qid.

#Illustrates optional fields, instances of subclasses, language fallback on label service, date to year conversion
#title: Horses on Wikidata
SELECT DISTINCT ?horse ?horseLabel ?mother ?motherLabel ?father ?fatherLabel (year(?birthdate) as ?birthyear) (year(?deathdate) as ?deathyear) ?genderLabel

Cats, with pictures

This query looks at all items with value of instance of (P31) equals to house cat (Q146) with a image (P18). The results are displayed as a gallery with the option '#defaultView:ImageGrid'.

#title: Cats, with pictures
#defaultView:ImageGrid
SELECT ?item ?itemLabel ?pic WHERE {
  ?item wdt:P31 wd:Q146;
    wdt:P18 ?pic.
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],mul,en". }

Map of hospitals

The query displays all items whose value of instance of (P31) is hospital (Q16917) or any subclass of (P279) of hospital (Q16917) with coordinate location (P625). The results are displayed on a map using 'defaultView:Map'.

#added 2017-08
#defaultView:Map
SELECT DISTINCT * WHERE {
  ?item wdt:P31/wdt:P279* wd:Q16917;
        wdt:P625 ?geo .

Try it!

Map of hackerspaces

The query displays on a map ("defaultView:Map") all items whose value of instance of (P31) is hackspace (Q1032372) and with values for property coordinate location (P625).

Warnings:

Number of humans in Wikidata

This query takes all items whose value of instance of (P31) is human (Q5) and count the total number of items using COUNT function.

#title: Number of humans in Wikidata
SELECT (COUNT(*) AS ?count)
WHERE {
  ?item wdt:P31 wd:Q5 .

Humans without children

Only truthy values

In the simplest form (using only truthy values):

#Demonstrates "no value" handling
#title: Humans without children (only truthy values)
SELECT ?human ?humanLabel
WHERE
{
  ?human wdt:P31 wd:Q5 .       #find humans
  ?human rdf:type wdno:P40 .   #with at least one truthy P40 (child) statement defined to be "no value"
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],mul,en" }
}
Humans without children (only truthy values)

Including non-truthy values

A similar query which also considers non-truthy (for example, values with deprecated rank) "no value" statements:

#title: Humans without children (including non-truthy values)
SELECT ?human ?humanLabel
WHERE
{
  ?human wdt:P31 wd:Q5 .         #find humans
  ?human p:P40 ?childStatement . #with at least one P40 (child) statement
  ?childStatement rdf:type wdno:P40 .   #where the P40 (child) statement is defined to be "no value"
  SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],mul,en" . }
}

Humans born in New York City

This example highlights the correct way to use the place of birth (P19) property, and by extension the place of death (P20) property. place of birth (P19) is the most specific known place of birth. For example, it is known that Donald Trump (Donald Trump (Q22686)) was born in the Jamaica Hospital (Jamaica Hospital Medical Center (Q23497866)) in New York City. Therefore, he wouldn't show up in direct query for humans born in New York City.

#title: Humans born in New York City
SELECT DISTINCT ?item ?itemLabel ?itemDescription ?sitelinks
WHERE {
    ?item wdt:P31 wd:Q5;            # Any instance of a human
          wdt:P19/wdt:P131* wd:Q60; # Who was born in any value (eg. a hospital)
# that has the property of 'administrative area of' New York City or New York City itself.

# Note that using wdt:P19 wd:Q60;  # Who was born in New York City.
# Doesn't include humans with the birth place listed as a hospital
# or an administrative area or other location of New York City.

Metabolite-metabolite interactions (mostly conversions) and their pKa change (federated query)

Federated query using the WikiPathways SPARQL endpoint to retrieve interaction information. The dimensions plot show the pKa changes during metabolite-metabolite interaction. It must be noted here that many very basic or very acidic are reported in pathways as the uncharged structure, whereas in normal biological pathways these compounds are charged and then have quite different pKa charges.
