I don't know if this is possible in Access - I can do it in Crystal but
haven't been able to figure out how in Access.

I have two tables - one shows the number of a response card sent back to us
(Survey_tbl). The other shows a range of response card numbers for a
particular region (Kits_tbl). There is one field in the Survey_tbl with the
response card number[KitNumber]. There are two fields in the Kits_tbl with
the response card numbers assigned to a region [KitStartNumber] and
[KitEndNumber]. I would like to be able to create a query joining the
Survey_tbl to the Kits_tbl. In Crystal, i am able to create joins that link
the [KitNumber] in the Survey_tbl to both the [KitStartNumber] and
[KitEndNumber] in the Kits_tbl, with a >= and <= join type. Is there any way
to do the same sort of thing in Access?

I'm not sure what you're asking about yet. You mention a ">= and <= join
type", but don't describe what they do. I don't know if Access can do that
because I don't know what "that" is...

More info, please...

yes. What you are looking for is a non-equi join. Unfortunately, you cannot
create or view this type of query in the query design grid.

If you know SQL well enough to type the SQL, go to the SQL view and create
just create the query. It would look something like:

SELECT S.*, K.*
FROM Survey_tbl as S
INNER JOIN Kits_tbl as K
ON S.KitNumber >= K.KitStartNumber
AND S.KitNumber <= K.KitEndNumber

If you are not comfortable with writing the query directly in SQL, then
create the query in the design grid as though you were doing equality joins.
Then, once you have the query created, switch to design view and change the =
signs to >= or <= as appropriate.
 
I am very rusty, here to scrape some off. My first thought was WHERE ....
BETWEEN ... Am I completely off target?

No. Some people prefer to avoid BETWEEN if there is a possibility that they
will need to port their code to a database that does not support that
keyword, which is simply syntactic "sugar" that makes writing the " ...<=
.... and ... >= ... " statement a bit easier.
Jet and SQL Server both support the use of that keyword.

I know MS SQL supports the Between ... and ... construct, BUT it is a bit
different from the way Access does it. In MS SQL (up to 2005 the latest
version I have) you must have the values in order lowest to highest or you
will get zero records returned. I assume that is because the SQL interpreter
changes X Between 20 and 1 to the equivalent of
x>=20 and x<=1

Access handles the statement a bit differently and effectively changes X
Between 2 and 1 to the equivalent of
X>=1 and X<=20

You're right, I forgot about that ... basically because it would never
occur to me to write the from...to values in reverse order :-)

Thank you guys - I was able to get this to work with the values in reverse
order. I had tried writing it myself prior to posting my question, and didn't
know about the reverse order thing. Works perfectly now.
