Querying unknown entity pages

{{#ask: [[Category:Deployments]][[~*Unknown_Deployment*]]

 |format=broadtable
 |limit=50
 |offset=0
 |link=subject
 |sort=
 |order=asc
 |headers=show
 |searchlabel=... further results
 |class=sortable wikitable smwtable
}}

Unknown Deployments 0000
Unknown Deployments 0001
Unknown Deployments 0002
Unknown Deployments 0003
Unknown Deployments 0004
Unknown Deployments 0005

last Unknown_Deployment

{{#ask:[[Category:Deployments]][[~*Unknown_Deployment*]]|format=plainlist|limit=1|offset=0|link=none|sort=|order=desc|sep=, |searchlabel=}}

Unknown Deployments 0005

Parse the last Unknown_Deployment string

• Start from the string: "Unknown Deployments 0001"
• extract the last 4 characters of strings: use parser function:
  • function:

    {{#sub:{{#ask:[[Category:Deployments]][[~*Unknown_Deployment*]]|format=plainlist|limit=1|offset=0|link=none|sort=|order=desc|sep=, |searchlabel=}}|-4}}

  • output: 0005
• add 1 to int Extension:ParserFunctions##expr

  • {{#expr: 1 + {{#sub:{{#ask:[[Category:Deployments]][[~*Unknown_Deployment*]]|format=plainlist|limit=1|offset=0|link=none|sort=|order=desc|sep=, |searchlabel=}}|-4}} }}

  • output: 6
• pad with zeros: Magic_words#Formatting padleft

  • {{padleft:{{#expr: 1 + {{#sub:{{#ask:[[Category:Deployments]][[~*Unknown_Deployment*]]|format=plainlist|limit=1|offset=0|link=none|sort=|order=desc|sep=, |searchlabel=}}|-4}}}}|4|0}}

  • output: 0006

Create Page & last unknown entity
