Return 0 if null

Hi all,
I have got a query that returns values based on a date range and grouped by
week. I need to return a value of 0 if there are no entries for that week. At
the moment it just skips that week all together.
Any ideas?
Thanks
Without more details, I'd suggest lookign into IsNull( variable, 0 ) or a
left outer join if you're using multiple tables and a lack of entries for
that week table is eliminating the week row. But to give a specific answer,
we'd need more details.

|||Hi Paul,
My current query is as follows.
SELECT Format([Counting Type_QRY].Date,'ww') AS Expr1, [Counting
Type_QRY].Branch, [Counting Type_QRY].Type, Sum([Counting
Type_QRY].CountOfType) AS SumOfCountOfType
FROM (Branch INNER JOIN Type ON Branch.ID = Type.ID) INNER JOIN [Counting
Type_QRY] ON Branch.ID = [Counting Type_QRY].Branch
GROUP BY Format([Counting Type_QRY].Date,'ww'), [Counting Type_QRY].Branch,
[Counting Type_QRY].Type;
This works great counting my entries and putting then grouping by week.
Trouble is if there is no info for a week it skipps that week.
34 = 4
35 = 2
37 = 7
I need it to return
34 = 4
35 = 2
36 = 0
37 = 7
I am fairly new to this so please excuse the query if it is not great. Just
trying to grow my skills in the real world.
Thanks

Sounds like you need an OUTER JOIN. I don't know your data, so use an
outer join against the table that may not have a foreign key
relationship. If you wanted all Accounts from the accounts table even if
some of the accounts didn't have a comment in the comments table, you
would:
From Accounts Outer Join Comments on Accounts.id = Comments.id

My problem is that I am querying a date range but there may not be entries
for all dates within that range in the table. I still need to return all
dates even if there is no data. Hence my previous
This works great counting my entries and putting then grouping by[vbcol=seagreen]
I really appreciate your input. Have been stuck for a bit and need to get
out of this hole!
Thanks.

Hi Andrew,
Looks like you need a calendar table.
