| Issue [https://sandbox.semantic-mediawiki.org/wiki/Issue/4965 4988]
| |
| | |
| == Description ==
| |
| Setting subobjects <code>cityN</code> with the property '''Has page''' to various cities and '''Has text''' to ''Unique''. Then, again "duplicating" the subobjects by creating <code>city10N</code> with the property '''Has page''' set to the same cities.
| |
| | |
| Afterwards, querying for the subobjects and showing the cities and their area/population/location using property chains.
| |
| | |
| In some cases, depending on how the parameters <code>sort</code> and <code>order</code> are used, the query does '''not''' return some property chain values from "duplicate" cities.
| |
| | |
| == Property declaration ==
| |
| <pre>{{#subobject:city1
| |
| | Has page = Athens
| |
| | Has text = Unique
| |
| }}
| |
| ...
| |
| {{#subobject:city101
| |
| | Has page = Athens
| |
| }}
| |
| ...
| |

| | |
| == Query ==
| |
| === Query 1 ===
| |
| <pre>
| |
| {{#ask: [[-Has subobject::Utilisateur:SMW user/Sandbox2]]|?Has page|?Has page.Has area|?Has page.Has population|?Has page.Located in}}
| |
| </pre> | |
| {{#ask: [[-Has subobject::Utilisateur:SMW user/Sandbox2]]|?Has page|?Has page.Has area|?Has page.Has population|?Has page.Located in}} | |
| Here no sort is used, i.e. the results are sorted by their subobject name. The problem is that some of the property chain values are '''not''' displayed at all.
| |
| <pre>
| |
| {{#ask: [[-Has subobject::Utilisateur:SMW user/Sandbox2]] [[Has page::Bangalore]]|?Has page|?Has page.Has area|?Has page.Has population|?Has page.Located in}}
| |
| </pre>
| |
| {{#ask: [[-Has subobject::Utilisateur:SMW user/Sandbox2]] [[Has page::Bangalore]]|?Has page|?Has page.Has area|?Has page.Has population|?Has page.Located in}}
| |
| Querying for the city directly shows all property chain values.

| {{#ask: [[-Has subobject::Utilisateur:SMW user/Sandbox2]][[Has text::Unique]]|?Has page|?Has page.Has area|?Has page.Has population|?Has page.Located in}} | |
| Here querying for the "unique" subobject, i.e. no duplicate properties, everything is displayed properly.

| |
| {{#ask: [[-Has subobject::Utilisateur:SMW user/Sandbox2]]|?Has page|?Has page.Has area|?Has page.Has population|?Has page.Located in|sort=Has page}}
| |
| Here <code>sort=Has page</code> is used, in contradiction to the previous query, all property values are displayed.

| |
| {{#ask: [[-Has subobject::Utilisateur:SMW user/Sandbox2]]|?Has page|?Has page.Has area|?Has page.Has population|?Has page.Located in|sort=Has page|order=rand}}
| |
| Here <code>sort=Has page</code> and <code>order = rand</code> is used, again, some property values are missing.

| Offtopic, here trying to use <code>sort=Has page.Located in</code>. While the property chain values are displayed correctly, the sorting doesn't work at all. Something else takes precedence, ruining the intended sort, turning it internally into <code>sort=<!-- subobject name -->,Has page.Located in</code>, <code>sort=Has page,Has page.Located in</code> or <code>sort=Has page</code>. Not sure about this, but something is fishy here. I know that up to SMW 3.1.6 the sort <code>sort = <property1>.<property2>,<property></code> is turned internally into <code>sort = <property>,<property1>.<property2></code>, ordering the property chains by length first; but here that it somehow ignores the second property chain part is very wierd.
