Send an e-mail to one person who has multiple products

Hey Experts!!
I have asked this question before, but I am still having issues with writing this query.

What I have is a database with 5 or 6 tables that are all related via a couple of keys. When the query is ran, you get a list of results composed of the following fields:

Client Table
"      Client name
"      Address
"      City
"      State
"      Zip
"      Etc
"      Client Key

Product Table
"      Serial
"      Primary Key
"      Client Key
"      Model Key
"      Etc

Contact table
"      First name
"      Last name
"      Phone numbers
"      E-mails
"      Etc.

The problem is that one customer could have 80 products and with the current SQL would receive 80 e-mails.  Is there a way to include all of their products in 1 shot without sending them 80 e-mails.  

My SQL:
SELECT DISTINCT (AED_Master.ACT_no) AS Expr1, Client.ACT_no, *
FROM (((Contacts RIGHT JOIN Client ON Contacts.ACT_No=Client.ACT_no)  
LEFT JOIN AED_master ON Client.ACT_no=AED_master.ACT_No)  
LEFT JOIN Models ON AED_master.Model_ID=Models.Model_ID)
LEFT JOIN Cat_Sub ON Client.CatSub_id = Cat_Sub.CatSub_id
WHERE (((Client.ACT_no)=?));

With the above SQL, I am still getting duplicate results.  I need to tame this so it is one contact/multiple products.
I can upload the Database if that would help, just let me know.  I am hoping this can be solved via a simple SQL variation, or if someone can write it for me and let me know why/what we did that?

Hi

You need to group by the ACT_no, and ergo, the other fields you want to extract. So, remove  the distinct, replace  * with the actual fields you want, and add a group by at the end listing all extracted fields.

The main problem with that is that I am not sure which fields the end-user will ultimately need.  Can I leave the *? Or would I have to list each field from each table??

SELECT Client.ACT_no, Client.Client, Client.Address, Client.Address2, Client.City, Client.State, Client.Zipplus, Client.County, Client.Area_Phone, Client.CatSub_ID, Client.Contact_no,
AED_Master.AED_no, AED_Master.ACT_no, AED_Master.Serial_Code, AED_Master.Model_ID, AED_Master.Adult_pads, AED_Master.Battery, AED_Master.Ped_Pads, AED_Master.Spare_Adult_Pads, AED_Master.Spare_Battery, AED_Master.Spare_Ped_Pads, AED_Master.Placement,
Models.Model_ID, Models.Model,
Cat_Sub.CatSub_ID, Cat_Sub.Category, Cat_Sub.Subgroup,
Contacts.ACT_no, Contacts.contact_salutation, Contacts.contact_first,  Contacts.contact_last,  Contacts.contact_position,  Contacts.contact_county,  Contacts.contact_phone1,  Contacts.contact_phone1_ext,  Contacts.contact_phone2,  Contacts.contact_phone2_ext,  Contacts.contact_fax,  Contacts.contact_email1,  Contacts.contact_email2
FROM (((CLIENT LEFT JOIN AED_MASTER ON AED_MASTER.ACT_NO=CLIENT.ACT_NO)
LEFT JOIN MODELS ON AED_MASTER.MODEL_ID=MODELS.MODEL_ID)
INNER JOIN CAT_SUB ON CLIENT.CATSUB_ID=CAT_SUB.CATSUB_ID)
LEFT JOIN Contacts ON Client.ACT_no=Contacts.ACT_no
WHERE ((Client.ACT_no) = 5132);

Hi

Yes, you are still getting the same results because you don't have a group statement. I understand you don't know which fields the customer wants to see, but your original request is to only get a unique email for each customer that has products. give them the option to click a button to see the full details. (Guessing which fields you need to group by)

SELECT Client.ACT_no, Client.Client, Client.Address, Client.Address2, Client.City, Client.State, Client.Zipplus, Client.County, Client.Area_Phone, Client.CatSub_ID, Client.Contact_no,
Cat_Sub.Category, Contacts.contact_email1,  Contacts.contact_email2
FROM (((CLIENT LEFT JOIN AED_MASTER ON AED_MASTER.ACT_NO=CLIENT.ACT_NO)
LEFT JOIN MODELS ON AED_MASTER.MODEL_ID=MODELS.MODEL_ID)
INNER JOIN CAT_SUB ON CLIENT.CATSUB_ID=CAT_SUB.CATSUB_ID)
LEFT JOIN Contacts ON Client.ACT_no=Contacts.ACT_no
WHERE ((Client.ACT_no) = 5132)
GROUP BY Client.ACT_no, Client.Client, Client.Address, Client.Address2, Client.City, Client.State, Client.Zipplus, Client.County, Client.Area_Phone, Client.CatSub_ID, Client.Contact_no,
Cat_Sub.Category, Contacts.contact_email1,  Contacts.contact_email2;

Thank you paisleym.  I do appreciate your patience and help with this issue.  I will be implementing the group by tonight.  I will post my results once I have finished implementing this code.

I am still getting multiple results for one single client.  Maybe the entire SQL needs to be rewritten for me to get the results I'm after.  I have this SQL from a different page that gives me exactly the results I'm after.
SELECT DISTINCT (AED_Master.ACT_no) AS Expr1, Client.ACT_no, * FROM (((Contacts RIGHT JOIN Client ON Contacts.ACT_No=Client.ACT_no)  LEFT JOIN AED_master ON Client.ACT_no=AED_master.ACT_No)   LEFT JOIN Models ON AED_master.Model_ID=Models.Model_ID) LEFT JOIN Cat_Sub ON Client.CatSub_id = Cat_Sub.CatSub_id WHERE (((Client.ACT_no)=?))
I know I have the distinct in there, but i'm wondering if that's what I am needing in order to get the results I'm after.
Your suggested SQL is below.  

SELECT Client.ACT_no, Client.Client, Client.Address, Client.Address2, Client.City, Client.State, Client.Zipplus, Client.County, Client.Area_Phone, Client.CatSub_ID, Client.Contact_no,
Cat_Sub.Category, Contacts.contact_email1,  Contacts.contact_email2,
AED_Master.ACT_no, AED_Master.Serial_Code, AED_Master.Model_ID, AED_Master.Adult_pads, AED_Master.Battery, AED_Master.Ped_Pads, AED_Master.Spare_Adult_Pads, AED_Master.Spare_Battery, AED_Master.Spare_Ped_Pads, AED_Master.Placement, 
Models.Model_ID, Models.Model
FROM (((CLIENT LEFT JOIN AED_MASTER ON AED_MASTER.ACT_NO=CLIENT.ACT_NO)
LEFT JOIN MODELS ON AED_MASTER.MODEL_ID=MODELS.MODEL_ID)
INNER JOIN CAT_SUB ON CLIENT.CATSUB_ID=CAT_SUB.CATSUB_ID)
LEFT JOIN Contacts ON Client.ACT_no=Contacts.ACT_no
WHERE ((Client.ACT_no) = 5132)
GROUP BY Client.ACT_no, Client.Client, Client.Address, Client.Address2, Client.City, Client.State, Client.Zipplus, Client.County, Client.Area_Phone, Client.CatSub_ID, Client.Contact_no,
Cat_Sub.Category, Contacts.contact_email1,  Contacts.contact_email2, AED_Master.ACT_no, AED_Master.Serial_Code, AED_Master.Model_ID, AED_Master.Adult_pads, AED_Master.Battery, AED_Master.Ped_Pads, AED_Master.Spare_Adult_Pads, AED_Master.Spare_Battery, AED_Master.Spare_Ped_Pads, AED_Master.Placement, 
Models.Model_ID, Models.Model;

Hi LZ1.

You may have solved this already. If you are getting too many results, then some of the select and group by fields need to be dropped. Without a whole lot of guessing about which fields are on which tables, it is difficult to advise which ones, maybe start with Models.Model and Models.Model_Id, etc.

I do see what your saying.  I will have to use a minimalist approach when writing this.  I will start with just the bare basics and go from there.  When I start getting more than what I need, I'll know where the problem lies.  
Thanks again fro all your help paisleym.
