Querying for queries

Template:Interlanguagelink: en

This help page describes how to query for information about inline queries. This is possible since Semantic MediaWiki 1.8.0 which introduced a mechanism to the parser functions #ask, #show followed by #concept1 in Semantic MediaWiki 2.5.0 that automatically stores information for the page they are used on as a subobject. This information includes the depth, the format, the size and the string of the respective query. Starting with with Semantic MediaWiki 1.9.0 the duration2 was added and Semantic MediaWiki 2.5.0 brought information about it's parameters3.

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

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

Result: 7088

The total number of pages containing queries

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

Result: 1243

The number of queries that use the format "count"

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

Result: 822

The number of pages that use queries that use the format "list"

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

Result: 309

Pages that have a query with format "ul" and one with format "table"

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

Result:

The 10 largest queries used on the wiki with their size and duration

{{#ask:
[[Has query::+]]
|?Query size
|?Query duration
|sort=Query duration
|order=desc
|limit=10
}}

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

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

Result:

	Query size"Query size" is a predefined property that collects the number of conditions used in a query and is provided by Semantic MediaWiki.	Query string"Query string" is a predefined property that describes the conditions of the query as a string and is provided by Semantic MediaWiki.

Property "Namespace" has a restricted application area and cannot be used as annotation property by a user.Property "Docinfo editor" (as page type) with input value "User:>MWJames" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.
