Limit report detail to date range

(Yes, the naming conventions on the tables and everything suck... I haven't worked in Access in, like, 15 years so this is my test database to get used to the updated UI, etc.  I'll redo it once I get proof of concept worked out)

I have a simple database with two tables:
1- Project List
2- Comments

Every project may have multiple comments.  Foreign-key between [Project List].ID and Comments.[Project ID]

Relevant field names are:
Project List.ID
Comments.Project ID
Comments.ID
Comments.Comment Date

Open in new window


My current report lists all projects (for a given Resource) and all comments.  I want my report to show all projects (for a given Resource), but only comments that are less than 2 weeks old (some projects will not have any comments in the relevant time frame).

Here is the current SQL View:
SELECT *
FROM [Project List] INNER JOIN Comments ON [Project List].ID = Comments.[Project ID]
WHERE [Project List].Resource=[ResourceFilter];

Thanks!

(1)   Change your INNER JOIN to a LEFT JOIN, which returns all rows from the left [Project List] table, and only matching values in Comments table.

(2)  WHERE DATEADD(d, -14, GETDATE()) > {whatever date column you're using}

Try this:

SELECT *
FROM [Project List] INNER JOIN Comments ON [Project List].ID = Comments.[Project ID]
WHERE [Project List].Resource=[ResourceFilter] AND Comments.[Comment Date] > DateAdd("d",-14, date())

Disregard my (2) comment, which was the SQL Server answer.  Miriam has the correct Access answer in the above comment.

@mbiz - close, but that's only returning projects that have comments within the specified date range

SELECT *
FROM [Project List] INNER JOIN Comments ON [Project List].ID = Comments.[Project ID]
WHERE [Project List].Resource=[ResourceFilter]
AND Comments.[Comment Date] > DateAdd("d",-14, date());

Open in new window


I need *all* projects but only comments from the last 2 weeks.
I've tried left joins, outer joins, inner joins, etc.

Super simplified example report.  In this example, Project 2 does not have any comments (status updates) within the past 2 weeks.

Project 1
	Comment from 4-JAN-2013
	Comment from 24-DEC-2012

Project 2

Project 3
	Comment from 27-DEC-2012

Just verifying... you tried Jim's LEFT JOIN suggestion?

SELECT *
FROM [Project List] LEFT JOIN Comments ON [Project List].ID = Comments.[Project ID]
WHERE [Project List].Resource=[ResourceFilter]
AND Comments.[Comment Date] > DateAdd("d",-14, date());

If that doesn't work, try Jim's LEFT JOIN, accounting for nulls like this:


SELECT *
FROM [Project List] LEFT JOIN Comments ON [Project List].ID = Comments.[Project ID]
WHERE [Project List].Resource=[ResourceFilter]
AND (Comments.[Comment Date] > DateAdd("d",-14, date()) OR Comments.[Comment Date] IS NULL)

Yes - that returns me only 8 records (which are the number of comments from the past 2 weeks)
I have 27 projects with 33 total comments.

So my report should return between 27 and 33 rows (at least one for every project, projects that have multiple comments in the time frame would appear twice)

Will try the "NULLS" now... one sec

Still only 8 records (those that have comments from the past 2 weeks).

In case it would be helpful to play inside the database.

The query I am adjusting is "qry-Project List Query w/ Comments"
It is used for the report "Report- Projects for Resource"

When it prompts you for a Resource, enter my name "Jason Dahlin"

Backing up a bit and removing the Date criteria...

Do you see the records you want to select when you run this query?

SELECT *
FROM [Project List] LEFT JOIN Comments ON [Project List].ID = Comments.[Project ID]
WHERE [Project List].Resource=[ResourceFilter]

Open in new window


What do you see in the Comments.CommentDate field for a representative set of the records that we are not picking up?

__

Edit:  I'll take a look at the db,

Ah - I follow what you're trying to do now.

You need a subquery to select the comment records in the date range.  That will get the limited set of comments you want.

If you then join the projects table on that subquery, you'll get all projects with any comments that fall into that date range.  The ResourceFilter creteria gets applied to the outer query:

SELECT *
FROM [Project List] LEFT JOIN 
(SELECT  * FROM Comments WHERE Comments.[Comment Date] > DateAdd("d",-14, date())) q
ON [Project List].ID=q.[Project ID]
WHERE ((([Project List].Resource)=[ResourceFilter]));

Is it something simple like your dates are wrong?  Change the line DateAdd("d",-14, date() to -7 or -21 and see what happens.

Perfect thanks!
"sub query" was the keyword I was missing.
