This page describes the WDQS interface and helps you to understand the various possibilities to display results on SPARQL query service. The query example page contains many good examples you can try!
Open the WDQS interface and then:
- select your language in
of the upper tool bar.
- write a valid SPARQL code in the text area.
- check your script by hovering the elements with your mouse; tooltips appear and should be consistent with what you intend to do. They adopt the language you have selected (default to english).
- then click on blue button Execute query of the sidebar to launch the request. Red square is lit in the sidebar while the command executes.
- after running a query, you can choose in the "Display" formats which result view you want to display. Depending on your query and the data type, some of the views will not be available.

# Recent events
SELECT ?event ?eventLabel ?date
WHERE
{
# find events
?event wdt:P31/wdt:P279* wd:Q1190554.
# with a point in time or start date
OPTIONAL { ?event wdt:P585 ?date. }
OPTIONAL { ?event wdt:P580 ?date. }
# but at least one of those
FILTER(BOUND(?date) && DATATYPE(?date) = xsd:dateTime).
# not in the future, and not more than 31 days ago
BIND(NOW() - ?date AS ?distance).
FILTER(0 <= ?distance && ?distance < 31).
# and get a label as well
OPTIONAL {
?event rdfs:label ?eventLabel.
FILTER(LANG(?eventLabel) = "en").
}
}
# limit to 10 results so we don't timeout
LIMIT 10

Note: You can also run directly a hardcoded request via the TryIt links of this page. When it brings you directly to the result display you can always return to the source script unsing the link at the bottom of the interface.
Table (default)
[edit]Shows the result data as a table. It is the default view for results and can display every data type.
Will map every variable from the SPARQL select clause to a formatted table column.

Table Result

Table Result on small screens with flipped columns
Image Grid
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/b/b1/WDQS_-_Image_Grid_Result_View.png/220px-WDQS_-_Image_Grid_Result_View.png)
Shows the result data as a grid with images.
Every grid item has a big picture and opens the gallery when clicking on it.
Contents an item is the formatted row data.
Variable | Data Type | Mapping | Description |
---|---|---|---|
* | Commons Media | Grid Item | Image columns will create a grid item. |
Rows containing no image will be ignored.
It’s nonetheless possible to include no image rows in the result by modifying the sparql by including a default image in case the image variable is not bound:
optional {
?item wdt:P18 ?img_ .
}
bind (if(bound(?img_),
?img_,
<http://commons.wikimedia.org/wiki/Special:FilePath/File:Profile_avatar_placeholder_large.png>) as ?image) # [[:commons:File:Profile_avatar_placeholder_large.png]] as a placeholder
Here the file commons:File:Profile avatar placeholder large.png is used as a placeholder, you can use your own.
See a complete query example using this technique.
Options
[edit]Option name | Type | Description |
---|---|---|
hide
|
One or more variable names (strings, starting with ? ), single value or array
|
Don’t show these variables in the result. |
Map
[edit]Shows the result data as map with OpenStreetMap data.
Variable | Data Type | Mapping | Description |

?layer | Map Marker Layer | Creates a colored map layer that allows filtering. | |
?rgb | Color | Color Map Marker | Example 000000 for black color. |
Technically, any well-known text literal can be displayed, not just a point coordinate.
Non-point geometry values are never stored on Wikidata, but they can be constructed in SPARQL using functions like CONCAT()
and STRDT()
–
see this map of Czech railway lines for an example of LINESTRING()
geometry.
Options
[edit]specify using e.g. #defaultView:Map{"hide":["?foo", "?bar"],"layer":"?bar"}

[edit]Result views are made to work on different devices and resolutions. Their appearance may change depending on the space they can use.
Embed Mode
[edit]Result views can be linked or embedded via iframes. You can get the regarding link or code by clicking Link in the above menu. See the difference: link to a query and link to a result or the embed code:
<iframe style="width:80vw; height:50vh;" scrolling="yes" frameborder="0" src="http://tinyurl.com/zwf4k2w">
Download results
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/8/84/WDQS_download_results_button_screenshot.png/220px-WDQS_download_results_button_screenshot.png)
There are several ways to export the results of a query.
JSON, TSV and CSV are three different open-standard formats to download the data, offered under the Download tab. To get results in XML format, click on Link > SPARQL endpoint.
You can also download some of the graphic views as a SVG file: this feature works with all the views except table, image grid, timeline, graph builder, map, and graph.
Default View
[edit]The default view can be change for each SPARQL query by using a comment:
#defaultView:[NAME]
For example:
#defaultView:ImageGrid
Result view options
[edit]Result views can be configured with various options, which are specified in JSON (Q2063) format, either following the defaultView
comment (see previous section) or following a separate view
comment.
#defaultView:Map{"layer": "?typeLabel"}
#view:ImageGrid{"hide": "?coords"}
Title
[edit]Result views can show a title. The title can be set via a title
comment.
#title:A title of your choice

Auto language
[edit]When using the magic keyword [AUTO_LANGUAGE]
it is replaced by the users language when submitting the query. This allows writing a query with where the result is displayed in the users language.
Example:
#Use language of the user for display labels and fallback to english as default
SERVICE wikibase:label {
bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" .
}
Auto coordinates
[edit]When using the magic keyword [AUTO_COORDINATES]
it is replaced by the users location when submitting the query (with clients accepting the geolocalization). This allows writing a query with the users' location.
Example:
#defaultView:Map
SELECT ?place ?coordinate_location ?dist {
SERVICE wikibase:around {
?place wdt:P625 ?coordinate_location.
bd:serviceParam wikibase:center "[AUTO_COORDINATES]".
bd:serviceParam wikibase:radius "1".
bd:serviceParam wikibase:distance ?dist.
}
}
