I'm fairly new to PHP/MySql and using queries in general. I was just wondering if there's any benefit to using "AS" in a query other than trying to make it look cleaner? Does it speed up the query at all? I probably could have figured this out by a google search but I wanted to ask my first question and see how this works. I WILL select an answer (unlike some people...)
with:
SELECT
news.id as id
news.name as name
FROM news
without:
SELECT
news.id
news.name
FROM news
A more complex example from a many-to-many relationship tutorial I found:
SELECT
c.name,
cf.title
FROM celebrities AS c
JOIN (
SELECT
icf.c_id,
icf.f_id,
f.title
FROM int_cf AS icf
JOIN films AS f
ON icf.f_id = f.f_id
) AS cf
ON c.c_id = cf.c_id
ORDER BY c.c_id ASC
