Handbuch:templatelinks-Tabelle

| MediaWiki Version: | ≥ 1.6 |
The templatelinks table contains for each current transclusion the id of the host page, the namespace number of the included page, and its title without namespace.
The target page may or may not exist, and due to renames and deletions may refer to different page records as time goes by.
Despite the name, transclusions are not limited to templates, nor to the MediaWiki parser's transclusion mechanism; various extensions use this table to mark that they have incorporated content from another page.
(E.g. Scribunto's {{#invoke:...}} and TemplateStyles's <templatestyles src="..." /> both record the target page in the templatelinks table.)
