Question

I think I can do this using Joins? How? Xampp doesn’t respond when I use this one. It doesn’t even show errors, just doesn’t do anything. Works with other queries.

SELECT * 
FROM acw_papers_web
WHERE id_paper_web IN (SELECT id_paper_web FROM acw_papers_web_autores 
WHERE nombre_autor_pw LIKE '%$autor%')

Answer 1

You can use JOIN like this:

SELECT web.* FROM acw_papers_web web
INNER JOIN acw_papers_web_autores aut
ON web.id_paper_web = aut.id_paper_web
WHERE aut.nombre_autor_pw LIKE '%$autor%'
