I have two tables
Email Contact History
Place of Service
that share a primarymembercustomerid. The Email Contact History has three fields:
Campaigncode
Primarymembercustomerid
maildate
and the Place of Service table has three fields
primarymembercustomerid
servicedate
serviceshortDesc
primarymembercustomerids are selected for E-mail campaigns, then if they walk into one of our branch offices and receive services, they show up in the Place of Service table. I want to count the number of primarymembercustomer ids that are mailed, and right next to it I want to have a count of primarymembercustomerids that showed up to a branch office.
What I have so far:
select
ch.campaigncode,
pos.serviceshortdesc,
count(ch.primarymembercustomerid),
count(pos.primarymembercustomerid)
from mktprodvm.cdmv_prmmbr_contacthist_email ch
right outer join mktprodvm.cdmv_pos pos on ch.primarymembercustomerid = pos.primarymembercustomerid
where ch.campaigncode = 'EDT_ALLACMO'
and pos.servicedate between '2017-02-01' and '2017-02-28'
group by 1,2
What I'm ending up with is a count of primarymembercustomerids that walk into a branch for that time period, but I'm not getting the total count of primarymembercustomerids that were E-mailed. I thought that by doing a right outer join I would get the total number of primarymembercustomerids that were mailed, but it's not working for me. I feel like I need to do some kind of subquery or correlated subquery, but I've ready about how to use them and I don't think that's right. I've never used them before and to be quite honest I'm not that great of a SQL coder either. Thanks for any help!
Because my low reputation on this site I can't comment, so I'm writing this as an answer.
I think that you are using the wrong type of join (or writing the tables in the wrong order). If you don't want to lose rows of your main table, the Email Contact History, you have to do a LEFT JOIN not a RIGHT JOIN.
Also, I don't know if it's possible, but I'm guessing that a primarymembercustomerid can have more than one service and since you are selecting the serviceshortdesc, a single Email might count in different rows of your anwerset and the total won't be accurate. According to what you said you want, I don't see a reason for including the service description in the SELECT.

I would like to create an SQL query for a "Role Call" which would show me the people who are inside the building only. Each person has his own access card and has to go in or out of the building using 1 of 4 turnstiles. So far I managed to retrieve the 4 turnstiles (in and out) data for todays date. I need to filter the list to only show people who had an "in" entry but did not leave yet. People can come and go as they please and use any of the 4 turnstiles and have multiple "ins" and "outs" per day.
I am bit stuck here how to do this.
I am joining 2 tables which have the device information (turnstiles) and the log of all swiped cards. I am filtering for the turnstiles data only and todays date.
SELECT [dbo].[lACLog].[LogID],[dbo].[lACLog].[LogDate],[dbo].[lACLog].[DeviceAddress],[dbo].[pPeriphery].[Name],[dbo].[pPeriphery].[PeripheryUID],
[dbo].[lACLog].[CardNr],[dbo].[lACLog].[Name],[dbo].[lACLog].[PersonalNr],[dbo].[lACLog].[PersID]
FROM [dbo].[lACLog]
LEFT JOIN [dbo].[pPeriphery]
ON [dbo].[lACLog].[DeviceAddress]=[dbo].[pPeriphery].[DeviceAddress]
WHERE [dbo].[lACLog].[LogDate]>=CAST(GETDATE()AS Date) AND [dbo].[pPeriphery].[PeripheryUID]
IN ('2130B72E-D8E9-4269-B6B0-68BEC95CB483',
'9229D4B6-5CD7-43E6-B7C7-BF9779333521',

So my basic goal is to create a database for a shopsystem, which is my task to do for my IT course. I tried to create a UPDATE-Query, that collects all the Sale Positions ("tblPosition.PositionAnzahl") ordered with a SELECT-Query and groups it by the products ordered, to have an overview about how often each product has been sold.
I want to do this to keep track of how many items are still left in the inventory.
The Query was supposed to update 1 field ("tblArtikel.ArtikelVerkauft") in my table "tblArtikel", in which all my articles and their information is stored.
However, i just found out that you cannot run UPDATE-Queries, that use SELECT-Query data, as i get a error, that says "Operation must use an updateable query".
This is the code i used for the query:
UPDATE tblArtikel as a JOIN
(SELECT p.PositionArtikelID, Sum(p.PositionAnzahl) AS SumOfPositionAnzahl
FROM tblPositionen as p
GROUP BY p.PositionArtikelID
) p
ON a.ArtikelID = p.PositionArtikelID
SET ArtikelVerkauft = p.SumOfPositionAnzahl;
Is there another way to keep track of all the Items left in my inventory, apart from doing what i did?
Here are screenshots of the 2 tables (the depending fields are circled red):
tblPositionen with field PositionAnzahl
tblArtikel with field ArtikelVerkauft
I have not worked with SQL before and only learned about it during 45 min, so ther emight be an easy way for this, but i would still appreciate every answer from you guys.
I'm in the process of building a database to keep track of loaning equipment. I'm trying to build a query that will display the latest record of each machines location.
Relevant table is:
Movements:
Movement ID (PK)
EntryDate (Automatically generated on record entry)
Serial (FK from a table called stock, with (Make, Model etc)
Location (Where the machine is)
Status (Things like: Available, Testing, Sold etc)
Current query is:
SELECT Movements.Serial, Max(Movements.EntryDateMovements) AS MaxOfEntryDateMovements
FROM Movements
GROUP BY Movements.Serial;
Which spits out the latest date of a record, and the serial associated with it.
What I need is the status to be shown in the results, but it still be grouped by the serial.
My issue is that when I try and add that, it either comes back with an error with about the expression not being part of the aggregate function, or I get more results than expected, as it no longer just keeps the results unique to the serial.
I'm pretty new Access, and have so far been able to muddle through guides, and books, and this site, to get everything else working, but i'm stuck at this hurdle.
Any help would be much appreciated.
Select top 1 *
from Movements
order by EntryDateMovements desc
This will give you everything for the newest record. This is TSQL but I think it carries over to Access.
Try this
Select t.serial,t.EntryDateMovements ,t.location, t.status
From movements as t
Inner join (SELECT Movements.Serial, Max(Movements.EntryDateMovements) AS MaxOfEntryDateMovements
FROM Movements
GROUP BY Movements.Serial) as MaxMovements on t.serial= MaxMovements.serial and t.EntryDateMovements=MaxMovements.MaxOfEntryDateMovements
I have a table 'ACCOUNTS', with fields ACCTNO and ACPARENT. One account can be the parent of another. One account can have many children.
It's been discovered that certain external processes are using the 'first child' in certain reports and outputs - but there's no actual 'reason' for any particular child to be 'first', just an unintended bug in the code.
First step in untangling this - I need a query, that can be re-run (but not often, so optimisation is not really a factor) that will identify, for all accounts that are parents, what their 'first child' is.
Problem - the 'first child' isn't necessarily anything to do with record ID. If I run the following query, for example:
SELECT ACCTNO FROM ACCOUNTS WHERE ACPARENT = '80005217';
I get a result of:
ACCTNO
______
80007325
80007310
80007315
80007298
I can absolutely, 100% confirm that for this particular example, account 80007325 is the account ID being used as the 'first child'.
On the flipside, if I run a naive query of:
SELECT A1.ACCTNO, A2.ACCTNO AS CHILDACCOUNT FROM ACCOUNTS A1
INNER JOIN ACCOUNTS A2 ON A1.ACCTNO = A2.ACPARENT
WHERE A1.ACCTNO IN
(SELECT ACPARENT FROM ACCOUNTS);
then if I scroll down to where 80005217 is the parent account, I see the following list:
CHILDACCOUNT
______
80007298
80007310
80007315
80007325
It's sorted, even though it's exactly not what I want.
Is there a query that will get me a list of what I want in a single query? A list of all parent accounts, and their 'first child' as returned by SQL unsorted?
To guarantee records coming in a fixed order we must provide the database with sort criteria in the ORDER BY clause. If there is no attribute which defines "first-ness" then no guarantee is possible. Without an ORDER BY clause the records are essentially in an uncontrolled order, although because of
database internals they often fall into some kind of pattern.
So, what makes account 80007325 the first child WHERE ACPARENT = '80005217'? Clearly not numerical order. Is there some other criterion? Date created? A flag column? Seems like you need to talk to your users. Do they really care which records come first? All the time or just in some specific report?
If your users cannot specify the criteria there's not much you can do...
...although I might be tempted to sort CHILDACCOUNT numerically by ACCTNO whenever it is displayed. At least that would provide consistency, and the users will get used to it.
So, basically, I have two tables called "dadoscatalogo" and "palavras_chave", with a common field, "patrimonio" which is the primary key of "dadoscatalogo".
I'm using a servlet to connect to the database with these tables, and passing a query to search for entries based on some search criteria that's defined by the user.
Now, since the user can search for entries based on information present in both tables, I need to do an INNER JOIN, and then use WHERE to search for that info. I'm also using LIKE, because the user may pass just part of the information, and not all of it.
So, to test it all out, I tried passing it a few parameters to work with, and see how it went. After some debugging, I found out that there was some mistake in the query. But I can't seem to be able to point out exactly what it is.
Here's the test query:
SELECT dadoscatalogo.patrimonio
FROM dadoscatalogo
INNER JOIN palavras_chave
ON dadoscatalogo.patrimonio=palavras_chave.patrimonio
WHERE dadoscatalogo.patrimonio LIKE '%'
AND dadoscatalogo.titulo LIKE '%tons%'
OR palavras_chave.palchave LIKE '%programming%';
So, basically, what I'm trying to do with this query is, get all the primary keys from "dadoscatalogo" that are linked to a record with a "titulo" containing "tons", or a "palchave" containing "programming".
PS. Sorry for the names not being in English, hopefully it won't be too much of a distraction.
EDIT: Right now, the tables don't have much:
This is the dadoscatalogo table:
http://gyazo.com/fdc848da7496cea4ea2bcb6fbe81cb25
And this is the palavras_chave table:
http://gyazo.com/6bb82f844caebe819f380e515b1f504e
When they join, I'm expecting it to have 4 records, and it would get the one with patrimonio=2 in dadoscatalogo (which has "tons" in titulo), and the one with palchave=programming (which would have patrimonio=1)
As per my understanding run below query:
SELECT dadoscatalogo.patrimonio
FROM dadoscatalogo
INNER JOIN palavras_chave
ON dadoscatalogo.patrimonio=palavras_chave.patrimonio
WHERE dadoscatalogo.titulo LIKE '%tons%'
OR palavras_chave.palchave LIKE '%programming%';
