Struggling with a query

Hello,
I am struggling with a query. And wondering if someone could help.

I have a table of tags (service request tickets)
and a table of serial numbers

From my tags I am doing this

Code:

Select * from tag 
where
tag.created
BETWEEN '2012-9-01'
AND '2012-12-29' 
and
tag.tagtype <> 'service'

Now,
i would like to join with serialnumber (table) where
(not sure inner/outer or just join)

tag.serialnumberid is in serialnumber.id
and serialnumber .modelid = 80

I am thinking it should be easy.
Any help would be appreciated

assuming you just want the data that there's an entry for in both tables, it should be something like this:

Quote:

Select * from tag
join serialnumber on tag.serialnumberid = serialnumber.id and and serialnumber.modelid = 80
where
tag.created BETWEEN '2012-09-01' AND '2012-12-29'
and tag.tagtype <> 'service'

if you also want the tags that have no matching serialnumber, you would use Left Join.
If you also want the serial numbers that have no corresponding tags, you would use Right Join
