Manual:Pagelinks table/zh

pagelinks标签囊括所有wiki内部标签 Each entry contains the source page's ID and namespace (number), and the article name (in text) and namespace (number) that is being linked to from within that source page. There may be many instances of the source page's ID, as many as the internal links within it, but there can be only one entry per internal link for any page ID (or MySQL will yell out a fatal error).

Note that the target page may or may not exist, and due to renames and deletions may refer to different page records as time goes by.

此功能只在版本1.5适用. It is the result of merging the table and the  table of version 1.4. Regenerating the pagelinks table is always possible using the maintenance script.

pl_from
Key to the of the page containing the link.

pl_from_namespace
of the page containing the link.

pl_namespace
Key to page_namespace of the target page. The target page may or may not exist, and due to renames and deletions may refer to different page records as time goes by.

pl_title
Key to of the target page. The target page may or may not exist, and due to renames and deletions may refer to different page records as time goes by. Spaces are converted to underscores, and the first letter is automatically capitalized. So for example, a link to foo bar would have a pl_title of "Foo_bar".
