This help page describes how to '''query for information about [[Help:Inline queries|inline queries]]'''. This is possible since [[Semantic MediaWiki 1.8.0]] which introduced a mechanism to the parser functions [[Help:Parser function ask|<code>#ask</code>]], [[Help:Parser function show|<code>#show</code>]] followed by [[Help:Parser function concept|<code>#concept</code>]][[CiteRef::gh:smw:1719]] in [[Semantic MediaWiki 2.5.0]] that automatically stores information for the page they are used on as a [[Help:Adding subobjects|subobject]]. This information includes the [[Help:Special property Query depth‎|depth]], the [[Help:Special property Query format|format]], the [[Help:Special property Query size|size]] and the [[Help:Special property Query string|string]] of the respective query. Starting with with [[Semantic MediaWiki 1.9.0]] the [[Help:Special property Query duration|duration]][[CiteRef::gh:smw:30]] was added and [[Semantic MediaWiki 2.5.0]] brought information about it's [[Help:Special property Query parameters|parameters]][[CiteRef::gh:smw:2270]].

This data can be queried as usual, e.g., to find out how many queries on the wiki use a particular format, or what are the largest queries.

== Examples ==

; The total number of queries
<pre>
{{#ask:
[[Query size::+]]
|format=count
}}
</pre>

'''Result:'''
{{#ask:
[[Query size::+]]
|format=count
}}


; The total number of pages containing queries
<pre>
{{#ask:
[[Has query::+]]
|format=count
}}
</pre>

'''Result:'''
{{#ask:
[[Has query::+]]
|format=count
}}


; The number of queries that use the format "count"
<pre>
{{#ask:
[[Query format::count]]
|format=count
}}
</pre>

'''Result:'''
{{#ask:
[[Query format::count]]
|format=count
}}


; The number of pages that use queries that use the format "list"
<pre>
{{#ask:
[[Has query.Query format::list]]
|format=count
}}
</pre>

'''Result:'''
{{#ask:
[[Has query.Query format::list]]
|format=count
}}


; Pages that have a query with format "ul" and one with format "table"
<pre>
{{#ask:
[[Has query.Query format::ul]]
[[Has query.Query format::table]]
|format=ul
|limit=10
}}
</pre>

'''Result:'''
{{#ask:
[[Has query.Query format::ul]]
[[Has query.Query format::table]]
|format=ul
|limit=10
}}

; The 10 largest queries used on the wiki with their size and duration
<pre>
{{#ask:
[[Has query::+]]
|?Query size
|?Query duration
|sort=Query duration
|order=desc
|limit=10
}}
</pre>

'''Result:'''

''Querying for the query duration is not enabled for this wiki.''


; The 10 largest queries used on the wiki with their size and query string
<pre>
{{#ask:
[[Query string::+]]
|?Query size
|?Query string
|sort=Query size
|order=desc
|limit=10
}}
</pre>

'''Result:'''
{{#ask:
[[Query string::+]]
|?Query size
|?Query string
|sort=Query size
|order=desc
|limit=10
}}
