links表

MediaWiki版本：

1.1 – 1.3

links和brokenlinks表已合并为pagelinks 表，它记录目标链接的名字空间+标题密钥对，而不是页面ID或带前缀的标题。 请参阅[1]

The links table stored all the links to existing articles. This was good for a variety of functions, from link caching in the output functions to the "what links here" page. It was the "good twin" of the brokenlinks table.

从MediaWiki 1.5版本开始，该表不再使用，并可以安全删除。 内容已在更新期间合并至pagelinks 。 Regenerating the pagelinks table always is possible using the rebuildall maintenance script.

Fields

l_from

l_from is the cur_id of the article that contains the link. (This is a change from 1.2, wherein the title of the article was stored. This was not very wise, and has now been fixed.)

l_to

l_to is the cur_id of the "target" article.
