I have 2 tables:
Table 1 Customers with column CustomerId
Table 2 Purchases with columns PurchaseId and CustomerId
I want to select all customers who have made just 1 purchase, what would be the sql for that? I know I can join the tables to get the customers with purchases, but I don't know how to limit it to those with just 1 purchase (and exclude all the other customers).
I've searched high and low for info on how to do this... If anyone has an idea, I'd really appreciate it.
I have three tables: PEOPLE, PROJECTS, COMMENTS. I want users from the PEOPLE table to retrieve a list of PROJECTS and be able to add/edit COMMENTS on those projects.
The tables look like:
PEOPLE
people_id (primary key)
first_name
last_name
PROJECTS
projects_id (primary key)
project_title
project_summary
COMMENTS
comments_id (primary key)
projects_id (foreign key)
people_id (foreign key)
comment_detail
I'd like to be able to output something like what I have below, but I don't know how to loop over the comments/people within the select statement for the projects.
DESIRED OUTPUT
Project #1
Comment #1 by Person #1
Comment #2 by Person #3
Comment #3 by Person #8
Project #2
Comment #1 by Person #2
Comment #2 by Person #3
Comment #3 by Person #6
Etc...
I've done it before by just listing the projects and then providing a detail page with all the comments, but it's much less confusing to access all the comments from the same page, grouped by project.
Thanks in advance.

I'm using SQL server 200
Table A has columns CompressedProduct, Tool, Operation
Table B in a differnt database has columns ID, Product, Tool Operation
I cannot edit table A. I can select records from A and insert into B. And I can select only the records that are in both tables.
But I want to be able to select any records that are in table A but not in Table B.
ie. I want to select records from A where the combination of Product, Tool and Operaton does not appear in Table B, even if all 3 on their own do appear.
This code return all the records from A. I need to filter out the records found in Table B.

SELECT ID, CompressedProduct, oq.Tool, oq.Operation FROM OPENQUERY (Lisa_Link,

JOIN tblOperation o ON ts.OperationID = o.OperationID
WHERE ts.ToolID=66
') oq
LEFT JOIN Family f on oq.CompressedProduct = f.Product and oq.Tool = f.Tool and oq.Operation = f.Operation
I have a large table of customers. I would like to add a column that contains an integer, unique to that customer. The trick is that this file contains many duplicate customers, so I want the duplicates to all have the same number between them.the numbers dont have to be sequential or anything, just like customers having the same one.

Hi,
Here is a basic example of the issue I am having:
Table 1 columns - name, address, zipcode, favorite food
For table 2 I want to find how many zipcodes exists and also take 20% of the count
Table 2 columns - based off Table 1 contains zipcode, count(zipcode) as ct, count(zipcode) * .20 as perc_ct
For example:
zipcode ct perc_ct
83746 10 2
93847 20 4
I want to run a query that will pull any 2 records for 83746 and any 4 records for 93847 from Table 1.
Is this possible?
Why is it my number of records are different from my view. this are the following code that that i used in my code and in my view.
my code in my program: this code show all the records i know
If iConn.State = ConnectionState.Open Then iConn.Close()
iConn.Open()
Dim rsBills As New Data.DataSet
rsBills = New DataSet

Wondering if there is a way to do this...
I want to select the DISTINCT user name from each record in a table, and then have another field tell me how many records it found..
is there any way to do this with SQL?
SELECT DISTINCT user_Name FROM table ORDER BY user_Name
is what I have now....
need something that will return:
user_Name numRecs
bob 3
fred 6
sam 1
linda 2
I have a resultset that looks something like this:
Anzahl users_statdata_hobbies
---------------------
499 Andere
266 Essen
60 Essen,Andere
127 Essen,Musik
10 Essen,Musik,Party,Andere
30 Essen,Party
4 Essen,Party,Andere
51 Kunst
4 Kunst,Andere
13 Kunst,Essen
4 Kunst,Essen,Andere
I get this with this query which might be altered somehow:
SELECT COUNT(*) AS Anzahl, users_statdata_hobbies
FROM vgetAuswertung2
GROUP BY users_statdata_hobbies
ORDER BY users_statdata_hobbies
Of course this is not normalized but I can't change this.
Nevertheless I need to get the full number of each Hobby and not only the combination of them.
So instead or in addition to the existing recordset I need e.g
357 Essen which ist the sum of all records containing 'Essen' in the above example
The list of individual hobbies is defined therefor I could loop through the list manually and search for 'WHERE Hobbies LIKE '%ESSEN%' and count but since it's quiet a big resultset and there are several other similar tasks already I'm looking for a more performant way and I'm sure it could be done in SQL directly.
Any ideas someone?
