Try this

Select sum(weight) from(
select ID, content_ID, 3 as 'weight'
from tblPage
where keywords LIKE '%test%'
union
select ID, content_ID, 2
from tblPage
where title LIKE '%test%'
) T

hi,

I'm building a simple search engine functionality for a client searching the
keyword and title and content of a page:

----
select ID, content_ID, 3 as 'weight'
from tblPage
where keywords LIKE '%test%'

union

select ID, content_ID, 2
from tblPage
where title LIKE '%test%'
-----

this results in a nice resultset, but now I want to sum the 'weight' values
so I can order by 'weight'....

Anyone any idea?

from tblPage
where title LIKE '%test%') as r

ah great,
I changed it to the following code, and it works:

----
Select ID, content_ID, sum(weight) weight
from
(
select ID, content_ID, 3 as 'weight'
from tblPage
where keywords LIKE '%test%'

union

select ID, content_ID, 2 as 'weight'
from tblPage
where title LIKE '%test%'
)
faketablename
group by ID, content_ID
order by weight desc
