Topic on Talk:Quarry

Full article text is not available in the Wiki Replica databases. Use the Action API or Dumps instead to get article content.

Can someone help me to write a query which gives the article content from Wikipedia articles in Telugu language

It is not possible to extract content from articles via Quarry (relevant tables are not publicly available).

But you can use the Special:Export page on your local wiki to get an w:XML version of the content of the pages.
