mysql joining two table without in common - mysql

Question

i have this script.. first i run query 1 and store into array then query 2,
using a foreach, i combine them and create a list of urls..but this takes time.. is there a way i can do this just in mysql by combining the table even do they have no common column?
query 1
SELECT
c.id,
c.city_name,
r.region_name,
cr.country_name
FROM city AS c, region AS r, country AS cr
WHERE r.id = c.id_region
AND cr.id = c.id_country
AND cr.id IN
(SELECT id FROM country WHERE used = 1)
query 2
SELECT id, title FROM param WHERE active = 1
loop
foreach ($arrayCity as $city) {
foreach ($arrayParam as $param ) {
$paramTitle = str_replace(' ', '+', $param['title']);
$url = 'http://url/city/'. $city['id'] .'/paramId/'. $param['id'] .'/'.
$paramTitle .'/'. $city['region_name'] .'/'. $city['city_name'];
}
}

Answer 1

You don't have to join on a condition. Not doing so is called a CROSS JOIN. The CROSS keyword is optional. In fact, you are already doing this because , is a synonym.
FROM city AS c, region AS r, country AS cr, param

Answer 2

How about
Select 'http://url/city/' + c.id + '/paramId/' + p.id + '/' +
Replace(title, ' ', '+') + '/' + r.region_Name + '/' + c.city_Name
From city c
Join region r On r.id = c.id_region
Join country n On n.id = c.id_country
cross join param p
Where n.Uused = 1
And p.active = 1

Answer 3

Something like this. You can select a concatenated string with results from your base table.
SELECT
c.id,
c.city_name,
r.region_name,
cr.country_name,
('http://url/city/' + c.city_name + '/' + p.param + '/' + c.id) AS URL
FROM city AS c, region AS r, country AS cr
JOIN param p ON c.id = p.id
WHERE r.id = c.id_region AND cr.id = c.id_country AND cr.id IN (SELECT id FROM country WHERE used = 1)
My experience is in TSQL, but it'll be close in my SQL
Edit: Sorry, forgot the join
