Is it possible to do something like this? Essentially I want to cast a int into a string and used the string on a join. Pay attention to the %t1.id%
select t2.*
from t1
join t2 on t2.url='site.com/path/%t1.id%/more'
where t1.id > 9000

You can do this:
select t2.*
from t1
join t2 on t2.url = 'site.com/path/' + CAST(t1.id AS VARCHAR(10)) + '/more'
where t1.id > 9000
Pay attention to CAST(t1.id AS VARCHAR(10))
.
Try it using CONCAT
CONCAT('site.com/path/','%', CAST(t1.id AS CHAR(25)), '%','/more')
select t2.*
from t1 join t2 on t2.url='site.com/path/%' + cast(t1.id as varchar) + '%/more'
where t1.id > 9000
Using concat like suggested is even better though
You could use CONCAT, and the numeric argument of it is converted to its equivalent binary string form.
select t2.*
from t1 join t2
on t2.url=CONCAT('site.com/path/%', t1.id, '%/more') where t1.id > 9000
If you have a column called "col1" which is int, you cast it to String like this:
CONVERT(col1,char)
e.g. this allows you to check an int value is containing another value (here 9) like this:
CONVERT(col1,char) LIKE '%9%'
