jbeck2010,
You have to understand basic syntax and the difference between field
names
with or without spaces. These two are not the same "Customer ID" and
"CustomerID". More experienced programmers never create field, table, or
object names with spaces. Those that use spaces must place []s around the
field names like [Customer ID].
By (returns one record) means that when you display the results of the
query
(you stated you had two that worked), you only see one record.

Duane,
On the 1 issue with the CustomerID, there is a space between Customer
and
ID
in the table. When I type it as it is in the table it gives a syntax
error
message about the SQL statement and when I type it as CustomerID it
gives
the
result I mentioned before. It doesn't work for me somehow. I must be
doing
something else wrong.
In Regards to the 2 queries, please clarify what you mean by (one
record).
Query 1 has 4 fields; Customer ID, Name, "Amount Purchased", Product
Type
Sum Active
And returns the value of the "Sum of Amount Purchased" by an Individual
from
many records.
Query 2 has 2 fields; Amount Purchased, Product Type
Sum Active
And returns the value of the "Sum of Amount Purchased" by everyone from
many
records.
Are you saying, if the queries are pulling information from more than
one
record you cannot combine the two queries or that if the query produces
one
total as the result of the query, it is one record, and you can combine
the
one total result fom each query in another query.
Duane, I am very appreciative of your patients with me on this subject
and
understand if you think I should seek other help. It seems as though
this
should be very simple, but for some reason I'm just not getting it.
Thanks for all your efforts on my behalf,

If you have two queries where one returns only one record, you can
create
another query with both queries as the source and then use fields from
both
source queries.

Duane,
Just one of my thoughts...It seems as though we kind of got off the
subject.
As I mentioned earlier, I have already setup the 2 queries that give
me
the
totals I need. The problem is combining those 2 totals in 1 query
and
producing a percentage based on those 2 totals.
The resulting query should look something like this;
Customer ID, Customer Name, Amount Puchased, Percentage of Total
Sold
1 John Smith 3200
32%
Thanks for your time and consideration,
jbeck2010
:
Make sure my table and field names match your table and field
names.
Then
begin creating a new query and select any table. From the query
design
view,
select to view the SQL view. The replace the existing SQL with:
SELECT Sum((CustomerID=1) * [Amount Purchased])/Sum([Amount
Purchased])
as
PctByCust1
FROM [table 2]
WHERE [Product Type]="Active";

Duane,
Thank You for your timely response. I'm sorry I have not got back
to
you
sooner with my progress. I've been tied up for a couple of days
in
meetings
on other projects.
Your expert guidance on the solution to my problem seems to be
the
answer,
but the real problem is that I don't know the proceedure to use
in
setting
up
Queries 1 & 3.
Is there a way for a simple minded guy like me to add the fields
in
the
design grid of a Select Query and then inter specific criteria to
obtain
the
needed results. If so, please explain the proceedure and specific
criteria
and where to indicate it.
Duane, I know the above might sound a little dense to someone
such
as
your
self, but any further help you can give me would greatly
appreciated.
I remain your greatlful student,
jbeck2010
:
Consider a query like:
SELECT Sum((CustomerID=1) * [Amount Purchased])/Sum([Amount
Purchased])
as
PctByCust1
FROM [table 2]
WHERE [Product Type]="Active";
If you need this for each customer, create a query
"qtotActiveSum"
like
SELECT Sum([Amount Purchased]) As TotalPurchased
FROM [Table 2]
WHERE [Product Type]="Active";
Then create another query
SELECT CustomerID, Sum([Amount Purchased])/TotalPurchased as
PctOfTotal
FROM [Table 2], qtotActiveSum
WHERE [Product Type]="Active"
GROUP BY CustomerID;

Duane,
*I hope this information will help you determine the correct
solution
for
my
problem.
You probably have already given it to me, but I don't quite
understand
how
to do it.
So, here goes... The Table Structures
Table 1 Table 2
Customer Personal Information Product Purchase
Information
CustomerID (Primary Key) CustomerID (Foreign Key)
Name Product (Unique
Number
for
each Purchase)
Address Product Type
(Active,
Canceled, Void
City Date
Purchased
State Price
Zip Code Amount Purchased
Home Phone
Work Phone
The above is the basic structure of the 2 tables. They are in
a
one
to
many
Relationship with table 2 being the many side.
What I'm trying to do seems very simple, but somehow I'm just
not
getting
it.
As far as the records you requested, I think I can make it
very
simple.
As
you look at the above tables a record consists of the
information
from
both
tables. The Basic difference in the individual records is who
purchased
and
on what date and the amount. The wildcard values are in the
Product
Type.
(See Table2)
*What I am try to do is setup a query that will calculate the
percentage
between the total amount of product an individual has
purchased
and
the
total
amount of product that has been purchased by everyone.
Query1 Example: CustomerID (1) John Smith 3200 Active
Query2 Example: Customers 10000
The result that I am looking for is CustomerID (1) John Smith
3200
32%
Active
Then I will use the query to generate a report on all
individual
customers.
Note* As customers purchase more product their percentage will
automatically
update.
Duane, I hope this is helpful to you in making your
evaluation.
As I've said before, I really appreciate your time and advise.
Best Regards,
jbeck2010

I don't know why you need to create two new tables where you
can
create a
totals/group by query to derive the recordset.
Maybe you need to provide your table structures, a few sample
records,
and
what you expect for results.

Duane,
Thank you for your helpful and timely response to my
question.
I'm trying to think through your suggestion and see if your
idea
about
a
unique ProductID will work.
For the moment, my problem is that I don't know how to
assign
a
unique
ProductID to the 2 different queries. There is only 1
Product,
but 3
different statuses
of that Product. (Active, Canceled or Void)
The database that I have designed is basically very simple.
It
has 2
main
tables;
1. Customer Personal Information (A very large table)
2. Product Puchase Information (Product,Type,Date etc.)
They are joined in a one to many relationship using the
customerID
as
the
Primary Key. The Product purchase information is the many
side.
All of the data input is done on 2 pages of 1 single form.
All
of
the
queries,forms and reports are based on those 2 tables.
Reports
are
automatically updated and self generated as the
information
is
input
on
those 2 pages of that 1 single form.
All I have to do is Print them.
Duane, after thinking through the above information that I
have
just
written
you maybe the answer is to create 2 other tables with a
unique
ProductID
as
you suggested and link them to the main tables somehow.
1. Total Product sold to one individual
2. Total Product sold to everyone
Do you think I'm on the right track or do you have another
suggestion.
Thanks again for sharing your expertise to an "Old Dog"
that
tryin'
to
learn
some new tricks.
God Bless and have a Great Day,
jbeck2010
:
Can't you create two totals queries where the ProductID is
unique
in
each
query. One query contains only orders from a single
customer
while
the
other
contains orders from all customers? Then join the two
queries
together
by
the ProductID?

Duane,
It was great to hear from you and thanks again for your
help
earlier
this
month.
I don't quite understand what you meant by SELECT
query1.*,
query2.*
FROM query1, query2; I assume it is code or an
expression
to
be
written
some
place or is it a proceedure?
Let me try to be a little more specific about what I am
trying
to
do.
The 2 queries are setup as follows;
1. Customer ID, Customer Name, Product, Product
Type=Total
Individual
Purchased
Sum
Not
Canceled
and
Not Void
2. Product, Product Type=Total Product Sold to Everyone
Sum Sold
*What I am trying to do is show the percentage one
Cusomer
has
purchased
in
relationship to the total Product sold.
Duane, I would like to thank you in advance for your
time
and
expert
advise
in solving my dilemma.
Best Regards,
jbeck2010
:
If each query returns only one record, you can combine
them
in
another
query.
SELECT query1.*, query2.*
FROM query1, query2;

I have setup 2 separate queries to get specific
totals.
It
is
impossible
to
combine them into 1, as they both use 1 key field
with
different
criteria
to
get the correct total.
Is there any way to calculate and display, in a query
or
report,
a
percentage as it relates to those 2 totals.
Example: Total bought 3,200 Total available 10,000
=
3,200/10,000=32%
All I Need is the percentage to show with the
appropriate
record,
not
the
calculation.
Please Help,
