Trying To Replace DSums By Subquery
Oct 25, 2007
Hi there,
THE GIVENS:
The following query works fine:
SELECT tblProjectSteps.ProjectID, tblProjectSteps.StepID,...,
NZ(DSum("Total","tblPayments","ProjectID=" & [ProjectID] & " AND StepID =" & [StepID],0)+
NZ(DSum("Total","tblReceivables","ProjectID=" & [ProjectID] & " AND StepID =" & [StepID],0)+
NZ(DSum("Total","tblBankPayments","ProjectID=" & [ProjectID] & " AND StepID =" & [StepID],0) AS TotalCosts
FROM tblProjectSteps INNER JOIN tblSteps ON tblProjectSteps.StepID = tblSteps.StepID;
The 3 summed tables (tblPayments,tblReceivables,tblBankPayments) do all of course have a foreign key for ProjectID (from tblProjects) and StepID (from tblSteps) and the output would be something like
STEPID.....ROJECTID....TOTALCOSTS
1.............100.............1100
2.............100.............1200
3.............100...............900
4.............100.............1300
1.............200...............700
2.............200.............1400
and so on...
THE PROBLEM:
For performance issues I would want to eliminate the DSum part, i.e get me a TotalCosts field by other means . I tried several constructions with multiple queries and also subqueries but to no avail. Any suggestions from the query Cracks her would be greatly appreciated.
Thanks
Jaime,

We are developing a complaints tool. Each completed complaint needs to be signed off by 3 leads and I'm hoping to display the progress of this in a form. Obtaining the first is simple and I was able to do that relatively quickly. The subsequence ones are now giving me a headache as it doesn't seem I can reference the initial subquery field in the others.Here's what I have so far:
Code:
SELECT COMPLAINT_TBL.COMPLAINTID, COMPLAINT_TBL.CASENUMBER, COMPLAINT_TBL.COMPLAINTANTFORENAME, COMPLAINT_TBL.COMPLAINTANTSURNAME, BUSINESSUNIT_TBL.BUSINESSUNIT, COMPLAINT_TBL.FINALRESPONSEDATE,
(SELECT TOP 1 [SIGNOFF_TBL].[SIGNOFFDATE] FROM [SIGNOFF_TBL]
WHERE [SIGNOFF_TBL].[COMPLAINTID] = COMPLAINT_TBL.COMPLAINTID
ORDER BY [SIGNOFF_TBL].[SIGNOFFDATE] DESC) AS FIRSTSIGNOFF,
[code]....

I have this working query:
Code:
INSERT INTO TB_SISTEMAS ( LOGIN, SISTEMA, PERFIL, DATA )
SELECT Left([dbo_BACKUP_ACESSOS.LOGIN],255) AS LOGIN, dbo_BACKUP_ACESSOS.SISTEMA, Left([dbo_BACKUP_ACESSOS.PERFIL],255) AS PERFIL, dbo_BACKUP_ACESSOS.DATA
FROM dbo_BACKUP_ACESSOS
WHERE (((dbo_BACKUP_ACESSOS.SISTEMA)<>"ACTIVE DIRECTORY") AND ((dbo_BACKUP_ACESSOS.DATA)="2014-03-23"));
But Iwant to be able to use a set of data to be used in the Replace Statement, so I create a table to add each string I would like to have replaced by "nothing", and trying to make the replace query to look there in order to find what to replace.I also created a table where I will list the systems that I dont want in the select, so I removed the "ACTIVE DIRECTORY" and replaced by the colum that have the list of system I dont want listed.This is the result:
Code:
INSERT INTO TB_SISTEMAS ( LOGIN, SISTEMA, PERFIL, DATA )
SELECT Replace((Left([dbo_BACKUP_ACESSOS.LOGIN],255)),[PREFIXOS_E_SUFIXOS]![Valor],"") AS LOGIN, dbo_BACKUP_ACESSOS.SISTEMA, Left([dbo_BACKUP_ACESSOS.PERFIL],255) AS PERFIL, dbo_BACKUP_ACESSOS.DATA
FROM dbo_BACKUP_ACESSOS
WHERE (((dbo_BACKUP_ACESSOS.SISTEMA)<>[SISTEMAS_EXCLUIDOS]![Sistema]) AND ((dbo_BACKUP_ACESSOS.DATA)="2014-03-23"));
The thin is that this keeps asking me to enter the parameter value for "PREFIXOS_E_SUFIXOS!Valor" and for "SISTEMAS_EXCLUIDOS!Sistema"

Can anyone tell me what is wrong with this complex query? It works fine without the highlighted subquery. The subquery works fine on its own. But they don't work together.
I think that I might not be able to call multiple results from a subquery but I'm not sure about that. Does any one know???
Any help will be much appreciated!
Thanks!

Hello
I have had a bit of a stumbling block with a subquery for a Daily production report and I was hoping someone could advise me.
An initial query presents the information as the table below.
Date ProdNoFirstOfSerialNoLastOfSerialNo Qty
13/11/2006004006P064600254P06460028128
13/11/2006004006P064600282P06460030019
13/11/2006004105P064600301P0646003033
13/11/2006004006P064600304P06460031714
13/11/2006004006P064600318P06460034427
However what I need to have is the table actually look like this,
Date ProdNoFirstOfSerialNoLastOfSerialNo Qty
13/11/2006004006P064600254P06460030047
13/11/2006004105P064600301P0646003033
13/11/2006004006P064600304P06460034441
I had thought to try and make another query identify the change of product number to then set the first and last serialNo's but I have no idea on how to write the statments necessary.
If anyone could offer some advice it would be very much appreciated.
Regards
Henson

Hi Chaps,
I haven't used subqueries before, so I am not 100% on the best way to approach this.
The Scenario:
I have tables;
tblJobDetails
tblMissingKit
tblSiteDeficiencies
JobID is the primary key for tblJobDetails. tblMissingKit and tblSiteDeficiencies are both tables containing (funnily enough) Missing Kit and Site Deficiences on the Job's (JobIDs) in tblJobDetails. The problem is, there can be more than 1 amount of missing Kit per JobID and more than 1 site deficiency per JobID.
In an ideal world, when I run this query, I would only get 1 record per JobID, but in a 'MissingKit' field, there would be a list of the missing kit for that site (new lines, comma seperated - doesn't matter) and then the same with Site Deficiencies.
Not sure if this is even doable, but thought I'd ask the people who know.
Thanks in advance,
Taz

Hello,
I've got two questions:
1) Can you use a parameter in a subquery?
2) Can the parameter value be the value from another field in the query?
In a nutshell, I want to write a query that returns these fields about some marbles:
Color of Marble
Marble Stat1
Marble Stat2
Marble Stat3
Number of Marbles of this Color
i.e. desired query results
Blue Stat1 Stat2 Stat3 24
Red Stat1 Stat2 Stat3 12
Green Stat1 Stat2 Stat3 38
The query is fine except for the last field, Number of Marbles of this Color. This field is a subquery with a parameter that is the color of the marble. So if I run the subquery on its own and pass 'blue' as the parameter, it returns 24.
Here is the SQL for the subquery, qry_Count_Marbles:
SELECT Count([Marble_ID]) AS [Count]
FROM tbl_Marble_Info
WHERE (((tbl_Marble_Info.COLOR)=[Marble_Color]));
Marble_Color is a parameter, and If I enter 'blue' it returns 24.
In my main query, I am trying to pass the parameter for the subquery as the result of the first field. It's not working, but here is my SQL:
SELECT tbl_Marble_Guidelines.COLOR, tbl_Marble_Guidelines.LOW, tbl_Marble_Guidelines.HIGH, tbl_Marble_Guidelines.FUND, qry_Count_Marbles.Count(tbl_Marble_Guidelines.COLO R)
FROM tbl_Marble_Guidelines, qry_Count_Marbles
I'd like the main query to not prompt the user for the parameter, but simply grab the parameter value from the value of the first field. Is what I'm trying to do possible? Is there a way to pass a SQL parameter within the SQL itself, and not prompt the user?
Any ideas?
Thanks,
Scott

Hi,
I am trying modify my forms so that I can display data like a tree view. I have a mainform and a subform. The source of the subform is a datasheet view of a query which has children linked to it. I have attached a snapshot view to this post.
How do I access a field in the child in the subform (it is not a subsub form - it is a subquery within a subform)? (Field need to be accessed highlighted in black in th snapshot)
Thanks

Ok at the moment, my sql statement works. However the return results is not arranged according to the earliest time. I've set DATATYPE for my Time as TEXT instead of DATE/TIME. This is because of other limitations in my forms.
Ok, that aside. This is how my SQL looks like:
Code:Select DISTINCT Time from Sample where Lot_No = 'BB55555' AND Product_Code='1234567'
Is there any way where by I can include Sample_id so that I can sort the Results using Order by Sample_id ASC?
i tried this but the DISTINCT doesnt work anymore.
Code:Select DISTINCT Time, Sample_id from Sample where Lot_No = 'BB55555' AND Product_Code='1234567' ORDER BY Sample_id ASC

Hi,
I have written a subquery that works fine alone, but it returns -1 when with query.
The subquery is supposed to return a total of type currency.
Any help/suggestions will be very much appreciated.
SELECT tblSite.Name, tblPhase.Phase_No, tblVariation_Order.Customer_No, Exists (SELECT Sum(tblVariation_Order.VO_Price)
FROM tblCustomer INNER JOIN tblVariation_Order ON tblCustomer.Customer_No=tblVariation_Order.Custome r_No
GROUP BY tblCustomer.Customer_No;) AS Expr1
FROM (tblCustomer INNER JOIN tblVariation_Order ON tblCustomer.Customer_No = tblVariation_Order.Customer_No) INNER JOIN (tblSite INNER JOIN (tblPhase INNER JOIN tblHouse ON tblPhase.Phase_No = tblHouse.Phase_No) ON tblSite.Site_No = tblPhase.Site_No) ON tblCustomer.Customer_No = tblHouse.Customer_No
WHERE (((Exists (SELECT Sum(tblVariation_Order.VO_Price)
FROM tblCustomer INNER JOIN tblVariation_Order ON tblCustomer.Customer_No=tblVariation_Order.Custome r_No

well here's my problem, i've been working on this homework for about 3 days i got most of my queries work except for the 2 that use nested or subqueries,
i have 2 tables
http://img251.imageshack.us/img251/4623/untitledko5.png
everytime i run the query i get this
http://img251.imageshack.us/img251/7645/untitled2rq0.png
i want the query to show me the costumers that have not made any orders, basically it should show me ID #6 no order,
when i use
SELECT Costumer.ID, Costumer.fname, Costumer.lname
FROM Costumer INNER JOIN [Order] ON Costumer.ID = Order.tblCostumer_ID
WHERE (((Costumer.ID) Not In ([Order].[ID])));
it returns the above pic of a blank query
this is what my POS book says i should type:
SELECT Costumer.ID, Costumer.fname, Costumer.lname
FROM Costumer
WHERE ID NOT IN (SELECT ID FROM Order);
but everytime i try that i get a syntax error after the NOT IN.
i don't know what else to try if anyone could help me out it would be greatly appriciated.

hi all,
i normally just go into design view in my query to change the format type, but some of my subqueries are quite large, so i'm getting 'the expression exceeds the 1,024 character limit for the query design grid.
i figured i could just multiply the subquery by 100, but the results are still calculated out to about ten decimal places.
so... how do i format a subquery directly in sql to be a percentage with two decimal places?
thank you,
mj

hi,
i have this "team" table with the following fields:
teamid, teamname
------------------
1, team1
2, team2
"game" table:
gameid, gamename
------------------
1, game1
2, game2
and "winlose" table:
id, gameid, teamid, winlose
---------------------------------
1, 1, 1, win
2, 1, 2, lose
3, 2, 1, win
4, 2, 2, lose
i want to generate a report in asp where each team have a total of win, total of lose and points calculated by : (totalwin*2)+(totallose*1)
teamid, Name, totalwin, totallose, pts
1, Team1, 2, 0, 4
etc...
the following query works pretty much well:
SELECT teamid, teamname,
(select count(winlose) from winlose where team.teamid=winlose.teamid and winlose='win') as win,
(select count(winlose) from winlose where team.teamid=winlose.teamid and winlose='lose') as lose,
(win*2)+(lose*1) as pts
FROM team
ORDER BY teamname
but the problem arises when i want to sort the report based on the "pts" which is the result of calculated two subqueries ("win" and "lose"), because i can't use the "ORDER BY pts" as access cannot order records by alias. can anybody find another sql solution to this?
theoritically i can just put all the records in an array and sort it by pts field, but sorting multidimensional with numerical and text array in asp kinda flakey at best, so i hope i can find the solution in the sql. thank you all in advance.

I have created this sub query:
Code:
(SELECT SUM(Cash)
FROM qryAccountSetup AS T2
WHERE T2.ClientID = [qryAccountSetup].ClientID
AND T2.MonthlyDate < [qryAccountSetup].MonthlyDate) AS PriorCash,
How do you change this to allow multiple values. I looked up subqueries online and it said to nest a second sub for the where clause....
Code:
(SELECT (Cash)
FROM qryAccountSetup AS T2
WHERE
(Select (SELECT MAX(T3.MonthlyDate)
FROM qryAccountSetup AS T3
WHERE T3.ClientID = qryAccountSetup.ClientID
AND T3.MonthlyDate < qryAccountSetup.MonthlyDate)) AS PriorCash,
But i keep getting error.
What i am trying to do is get the previous cash value.... For now, a good indicator is MonthlyDate, as only one date per client will exist. Something can only happen once in a day....IE.
ClientID..MonthlyDAte
1...........03/01/2013
1...........31/01/2013
1...........01/02/2013
1...........and so on.
There can be multiple dates, however the clientID would not match then.... Does this make sense? There is also a PositionID... This is an autonumber field in its respective table.. I have that so i can use it for domain purposes in the future.

Hello,
This db I'm working on tracks the latest revisions of drawings. Multiple drawings fall under a work package, and multiple revisions of a drawing are present (listed 1, 2, 3, ...). I want to pull information about the latest revision of a drawing, including the drawing number, the tracking ID from the tbl_wkpkg_dwg_rev table, and the corresponding dwgTitle from tbl_dwg. The tables are joined through the field wkpkg.
I have my select statement partially working; it works on one table. This is what it returns:
dwg1 3 id1
dwg2 1 id2
dwg3 5 id3
Here is the statement:
SELECT r.dwg, r.revision, r.trackingID
FROM tbl_wkpkg_dwg_rev r, (SELECT MAX(revision) as maxrev, dwg FROM tbl_wkpkg_dwg_rev GROUP BY dwg) MaxResults
WHERE r.dwg = MaxResults.dwg
AND r.revision = MaxResults.maxrev;
So I would like to join it to tbl_dwg and get:
dwg1 3 id1 DrawingTitle1 wkpkg1
dwg2 1 id2 DrawingTitle2 wkpkg1
dwg3 5 id3 DrawingTitle3 wkpkg2
However, when I try and join it with tbl_dwg to get the other information, it returns this:
dwg1 3 id1 DrawingTitle1 wkpkg1
dwg1 3 id1 DrawingTitle1 wkpkg1
dwg1 3 id1 DrawingTitle1 wkpkg1
dwg1 3 id1 DrawingTitle1 wkpkg1
dwg2 1 id2 DrawingTitle2 wkpkg1
dwg2 1 id2 DrawingTitle2 wkpkg1
dwg2 1 id2 DrawingTitle2 wkpkg1
dwg2 1 id2 DrawingTitle2 wkpkg1
dwg3 5 id3 DrawingTitle3 wkpkg2
dwg3 5 id3 DrawingTitle3 wkpkg2
dwg3 5 id3 DrawingTitle3 wkpkg2
dwg3 5 id3 DrawingTitle3 wkpkg2
dwg3 5 id3 DrawingTitle3 wkpkg2
I tried using SELECT DISTINCT, with no luck. I'm out of ideas, so any help would be appreciated! :confused:
Thank you!

Extended Cost] and salestran.[Extended Price] for each salestran.[SKU Code/Number], Count the number of unique customers, salestran.[Customer Code/Number], per SKU for any transactions equal to or after salestran.[Transaction Date] 11/1/2014.
Problem is, doing a regular count on the Customer field returns an incorrect value. It counts the number of times the sku appears within the given date range, ie 6 transactions with 2 customers, my count says 6. I need a distinct count on the customer, for the above example I want to see 2. Here is the code I have so far which yields an error of "At most one record can be returned.." distinct count in my Select statement along with the other fields I want to see, ie Summary data and SKU.
SELECT Salestran.[SKU Code/Number], (SELECT COUNT(cd.[Customer Code/Number]) AS Count FROM (SELECT Distinct [SKU Code/Number], [Customer Code/Number] FROM Salestran) as cd GROUP BY cd.[SKU Code/Number]) AS [Number of Customers]
FROM Salestran

I need to select a record with the latest (max) date along with associated values that go along with that record. However, some records have the same date. Initial query sorts by Asset_ID and Date (Desc)...A second query against the initial query then groups by Asset_ID, taking the Max Date and First Switch and Port...Results show the latest date but with a different Switch and Port
Asset_ID | Date | Switch | Port
123 23/05/2013 WAR01 GI01
123 23/05/2013 SAM01 GI02
123 20/05/2013 ROC01 GI03
123 21/05/2013 CHR01 GI04
e.g I get 23/05/2013 with ROC01 | GI03...I have tried doing this as a nested query but get similar results.

Does access have WITH subquery, For example creating a variable that stores a whole subquery such as:
Code:
WITH variableTEST (a, b, c, d, e) as
(SELECT a1, a2, a3, max(ab), count(*) as nbids
FROM A x natural join B y
WHERE x.something > y.something
GROUP by a1, a2, a3)
WITH variableTWO (f, g, h, i, j, k, j) as
(SELECT A.bidder, W.a, W.b, W.c, W.d, W.e, A.something
FROM variableTEST W natural join B A
WHERE W.sprice = B.bidprice)
SELECT h FROM variableTWO WHERE now - j <7
Can it do something like this, if not what alternative do they have to do something similar? Using WITH and subquery and variable, and storing variables and then later use it again in another subquery, can it do something like this in access SQL?

I'm doing a subquery to select the top 5 of products for each supplier. The selection needs to be done randomly on the products for each supplier. For this I have made the following query (based on Allen Browne's example):
SELECT tblProducts_temp.SupplierID, tblProducts_temp.GTIN
FROM tblProducts_temp
GROUP BY tblProducts_temp.SupplierID, tblProducts_temp.GTIN
HAVING (((tblProducts_temp.GTIN) In (SELECT TOP 5 Dupe.GTIN
FROM tblProducts_temp AS Dupe
WHERE Dupe.SupplierID = tblProducts_temp.SupplierID
ORDER BY RND(Dupe.GTIN) DESC)))
ORDER BY tblProducts_temp.SupplierID, tblProducts_temp.GTIN;
The query returns a random number of products, but not a top 5. So for supplier X one time 3 products and the next time for supplier X 7 products.The query without the RND function, so just the top 5 works fine:
SELECT tblProducts_temp.SupplierID, tblProducts_temp.GTIN
FROM tblProducts_temp
GROUP BY tblProducts_temp.SupplierID, tblProducts_temp.GTIN
HAVING (((tblProducts_temp.GTIN) In (SELECT TOP 5 Dupe.GTIN
FROM tblProducts_temp AS Dupe
WHERE Dupe.SupplierID = tblProducts_temp.SupplierID
ORDER BY Dupe.GTIN DESC)))
ORDER BY tblProducts_temp.SupplierID, tblProducts_temp.GTIN;

There are 2 mainforms and both of them share a subform. This subform is an add subform and I want the mainform to be refreshed after the data entry.Prior to the sharing, I had it coded it the way below and it works fine
Code:
Forms!frmMainformnoproc!frmActiveTasks.Requery
How would I recode this requery when it shared between 2 forms. frmMainformnoproc is the name of one of the main forms.The code above was present after an update was completed in the subform. Maybe I should be doing it after I close the subform and refresh the mainform. Based on that line of thinking I tried to add the code in the Activate event / Got Focus event of the mainform but the form did not get refreshed.

I have a one-to-many query which I would like to add a subquery to eliminate all but the TOP 1 of a field.
Here is the SQL:
Code:
SELECT QrySitesBatteries.SiteKey, QrySitesBatteries.SITEID, QrySitesBatteries.Battery
FROM QrySitesBatteries
WHERE (((QrySitesBatteries.Battery)=[Forms]![FMHome]![Battery])) OR ((([Forms]![FMHome]![Battery]) Is Null))
ORDER BY QrySitesBatteries.SITEID;
And I would like to only show the TOP 1 of the SiteKey field.
So, I think I have to add the subquery before the ORDER BY, but how to do it?

I have a subquery on a table which got the previous and next rows from a table. This worked fine, until I started replacing my table with real data instead of dummy-data. I now receive the "at most one record can be returned by subquery" error every time I run it. I checked that I do not have any identical rows.
My query:
Code:
SELECT z.DateFrom, z.DateTo, z.ArticleID, z.retailerID, z.Actuals, z.Statistical, (SELECT y.Actuals FROM tblActuals AS y WHERE (y.retailerID=z.retailerID) AND (y.ArticleID=z.ArticleID) AND ((DatePart("ww",z.DateFrom,2,3)-1)=DatePart("ww",y.DateFrom,2,3))) AS ActualsMin1 FROM tblActuals AS z;
I append new rows via a VBA-script from another table.

I have a strange 'bug'.
I wrote a query to return the TOP 32 items for a key. Works fine:-
SELECT TOP 32 [my Disks Coefficients sub].[thier Disk ID] FROM [my Disks Coefficients] AS [my Disks Coefficients sub] WHERE [my Disks Coefficients sub].[my Disk ID]=1 GROUP BY [my Disks Coefficients sub].[thier Disk ID], [my Disks Coefficients sub].coefficient ORDER BY [my Disks Coefficients sub].coefficient;
I then plugged this into a query in the WHERE clause using In (Select Top .....;); [changing the =1 condition to pick up the correct id from the emcompassing query]:-
SELECT [my Disks Coefficients].[my Disk ID], [my Disks Coefficients].[thier Disk ID], [my Disks Coefficients].coefficient FROM [my Disks Coefficients] WHERE [my Disks Coefficients].[thier Disk ID] In (SELECT TOP 32 [my Disks Coefficients sub].[thier Disk ID] FROM [my Disks Coefficients] AS [my Disks Coefficients sub] WHERE [my Disks Coefficients sub].[my Disk ID]=[my Disks Coefficients].[my Disk ID] GROUP BY [my Disks Coefficients sub].[thier Disk ID], [my Disks Coefficients sub].coefficient ORDER BY [my Disks Coefficients sub].coefficient;);
This runs fine but the the number of items returned is for each key is less than if I run the Top query by itself for each key seperately? So when I run it stand-alone for ID 1 I get 127 rows (there are many equal coefficients); when I run it as a sub-query I get only 121 rows for ID 1!
Anyone any ideas?
