Question

I am working on exiting project. I want to join two tables in SQL query.

$this->chapterPages = Doctrine_Query::create()
                     ->from( 'Page' )
                     ->leftJoin('PageAnchor pa ON pa.page_id = Page.sortorder')
                     ->where( 'Page.chapter_id = ?', $this->chapterId )
                     ->execute();

$this->chapterPages = $this->chapterPages->toArray();

But I am getting following error:

“PageAnchor” with an alias of “pa” in your query does not reference
the parent component it is related to., referer: example.com/abc/abc

Any idea ?

Try this:

$this->chapterPages = Doctrine_Query::create()
                 ->from( 'Page p' )
                 ->leftJoin('p.PageAnchor pa ON pa.page_id = Page.sortorder')
                 ->where( 'Page.chapter_id = ?', $this->chapterId )
                 ->execute();
