Difficult Duplicates Query
Apr 15, 2008
Hi all,
I have 2 tables, namely: Projects and WeekUren
Where [WeekUren] contains multiple references to unique records in [Projects].
[WeekUren] has the following collums which are important:
-ProjID
-Week
-Persoon
Where these three always form an unique combination. For instance:
1 | 1 | 1
1 | 2 | 1
1 | 3 | 1
1 | 1 | 2
1 | 2 | 2
2 | 1 | 2
Saying: Person1 will work week 1 till 3 on Project1, Person2 will work week 1 and 2 on Project1 and week1 on Project2.
Weeks are here relative to the project start date (a value of [Projects]) and always start with and increment with 1. So week1 of Project 1 and 2 don't neccesarily fall on the same dates, hence Person2 is still able to work both Projects.
Bear with me here.....
Now I need to select all duplicate records (where people are assigned to two (or more) projects in the same real week.
Real week is defined by:
Code:DatePart("ww",((WeekUren.Week-1)*7+(SELECT Projects.Start FROM Projects WHERE Projects.Id=WeekUren.ProjId)))
And the Query to convert [WeekUren] in to the relative form is:
Code:SELECT WeekUren.Id, DatePart("ww",((WeekUren.Week-1)*7+(SELECT Projects.Start FROM Projects WHERE Projects.Id=WeekUren.ProjId))), WeekUren.Uren, WeekUren.Persoon, WeekUren.ProjIdFROM WeekUren;
The query to print out duplicates is ofcourse:
Code:SELECT *FROM WeekUrenWHERE (((WeekUren.Week) In (SELECT [Week] FROM [WeekUren] As Tmp GROUP BY [Week],[Persoon] HAVING Count(*)>1 And [Persoon] = [WeekUren].[Persoon])))ORDER BY WeekUren.Week, WeekUren.Persoon;
Sofar so good, combination of the two however give me a syntax error. Hence my question here how to construct such a diabolical Query. Thanks!
Regards,
Jacco

I have Two fields with DateWorked and EmployeeNumber. All I want to do is count the number of employees that worked on a specific date. In the employee numbers I have 4 dummy numbers that I don't want to count in my query (00001-00004), but will have entries almost each day. The rest are 5 digit numbers.
Some employee will work some days, but not others.
So I set up my query with:
EmployeeNumber
Table
Total: Count
Criteria: >4
I did that think that it would count all employee numbers great than four, but all it seems to do is give me the count of days that more than 4 employees worked.
What am I doing wrong? I feel like this is simple, but after some of the more complex things I've done over the past week, this seemingly "easy" thing has me stumped.

I think i'm making this more difficult than it is.
I have an 2 excel spreadsheets with sales numbers like this -
Zip CustomerType Sec Hes Fol
10001S0303.230
10002C-373461.391531.8
10577S-71.25287.560
11211C0702.220
11803L14365.27-45
12401S0280.990
12524W0178.320
One file is numbers I averaged over the past 3 months. The other file is actual numbers. Not all zip codes are in each file. I need to figure out the difference between the 2 and add the difference to this months numbers. So I created a query and found there were 94 records that matched based on zip cod and customer type. Then I found the difference in sales amounts. Now I'm stuck at figuring out which zip code and customer type don't match in the 2 files. So if zip code 10001 with customer type S isn't in the actual data for this month I need to add the zip code and customer type and have it be -303.23.

Hey,
I’ve posted on here a few times lately, as I’m creating a database at work. It is going to be used to keep various information about new persons applying for jobs, and I want it be viewed/sorted by either 'Job Grade' or 'Job Title' I keep doing a lot, and then getting stuck on certain things. I’m stuck again, but I think it’s a little more difficult this time…
What I would like to happen is have the database open up, and a screen appears with two choices – ‘View by Job Title’ and ‘View by Job Grade’. When you click one, a new screen appears and a list of some sort appears with all of the job grades / job titles (depending on which button is pressed) on that are currently in the database.
From here, you can choose a job grade / title and it will bring up the form I have created – but only with the records that have the chosen job grade / title.
So for example, there could be 20 records in the table. 5 with job title ‘Manager’, 5 with job title ‘Assistant’. Then there could be 5 jobs with grade ’1’ and 5 jobs with grade ‘2’. When you clicked on ‘View by Job Title’ and then choose ‘Manager’, the 5 records with the job title ‘Manager’ would come up.
I hope I’m making sense so far.
The data would all be stored in one main table, and I already have the form created, so it would be good if I could use this.
Is there any way to do all of the above?
If anyone could help at all, it would be very much appreciated.
Cheers
Dan

I have a solution for my problem, I just want to see if there is an easier way. Here is my predicement:
From...........To..............c
0...............100............5
100............500............10
500...........1000...........15
1000.........3000............25
3000.........5000............30
5000........10000...........40
10000.......30000...........50
30000.......50000...........60
(This means: Between the amount of 0 and 100, the eventual amount equals to 5. Between 100 and 500, the evebtual amount is 10. etc. etc.)
Over the amount of 50,000 for every 5,000 the amount goes up, the eventual amount (column c) goes up 10, with the condition the eventual amount (column c) should not be over 500.
My current If-statement: Eventual Amount:
IIf([Amount]<100,5,IIf([Amount],500,10,IIf([Amount]<100,15 etc. etc.)))
Is there an easier way to do this... It's going to take mighty long to do it like I am currently doing it.
Thanks a lot

I have a database for my company which I am making.
The products are hydraulic cranes and come in numerous models (or sizes), in turn these models come in numerous versions, 5 different ones in all, lets call them for simpleness 1-5. However, some cranes come in versions 1-3 only, others 4-5 only, some all versions and no-doubt some a random mix!
At present I have a table with the fields "Model" (Text), and seperate fields for each "Version" (ie. 1, 2, 3 etc), these are Yes/No tick boxes. Ticking a given box for any given model, means that only these options are available on a form. Ie When you select a "400" crane, you can for example only select Version numbers 1, 2 and 3 - those that are checked in this table.
What I need to do is when selecting each individual model on a particular order is to display 2 figures hydraulic oil flow-rate and also hydraulic pressure required from a reference table I assume. These figures are different for every given model/version combination.
The difficult part as I see is relating the yes/no check box from the table above to version number on the reference table.
Does this make any sense? My head hurts.
Any Help would be super!

Hi Everybody. I've been nosing around here because I have this difficult problem with a database design. I modelled my program in UML so I have a class diagram. Now I want to create an access database out of it, but this is too hard for me.
It's about a school project for flowers. Every year, they make a cross plan. This cross plan contains crossings. Many crossings. And every crossing exist from 2 genotypes. A mother and a father. With this crossing several new genotypes are created. How on earth do I realize that in a database? A plant is male as well as female so you don't need to indicate which sex it is.
Further more I want a genotype to be judged on his characteristics by a user as much as he wants to.
Well...I hope someone can help and if you have questions about it don't hesitate to ask.
Thanks in advance!

Hi all
I have a financial database that gets downloaded transactions off the internet from our accounts. The problem is that the transaction payer/payee is not always unique and needs to be classified. This is easy done using If statements but I really want to enter parts of the string into a table and have a query return a category for this payer/payee. Example:
I want this: AUTO ONE CLARKSON CLARKSON WA AU006495
to be recognised as: car parts
or with this tranaction:
CLARKSON MINI MART CLARKSON553908
look for "mini mart" and return supermarket
This step will make classifying transactions a lot simpler and user friendly.
thanks

Alright, so my pride and joy and departmental savior database has been fully implemented and people are so pleased with it that they *all* want to use it at the same time. Initially, I made it custom for three peoples' UI preferences, but since it's such an intuitive design, other staff now feel comfortable using it instead of passing the work down the line to the one person who knows how to use that "newfangled thing".
A couple years ago, I used FMPro and allowing for multiple users at once was an annoyingly complicated process dealing with permissions and rights and accounts and passwords and yadda yadda. Is it any easier to set up in Access? Does anything special even need to be done to allow for multiple simultaneous users?

Hi,
This is a toughie (i think so anyway!). I'll attempt to explain!!!
I start with a CONTINUOUS form in my DB that shows all readings for a single given customer's connections. E.g. Customer A has 5 connections and each connection has say 3 readings. Thus this query which uses joins between the Customers, Connections, and Readings tables, would return a list of all readings for each connection, so in the above example: 1*5*3 = 15 records.
Not too tricky so far, but then what I want is for each connection to have just one line showing the latest reading (easily achieved by use of SQL Aggregate Max function on the date field coming from the readings table) TOGETHER WITH the last-but-one (next most recent) reading. So back to the example taking Customer A's connection 1, the row would be as follows:
Cust Conn CurReading PrevReading
A 1 750 500
Where the CurReading value (750) comes from a different record than PrevReading (500).
I've tried all sorts of ways (subqueries etc.) to achieve this without success. The main problem being that any sub query would require parameters from the current record's fields, which seems not to be possible. Can anyone help or is this simply not possible in MSAccess Forms. If it isn't possible anyone have any suggestions as to an alternative way?
Thanks
Darren

Hi this is my first post... so hi all :)
ok what i have is a table with contact details 900k plus
there are about 90k of which are duplicates.
this is the basic feilds that are important in this case.
Id, data_source, data_recived, data_code,
what i want is to have a table with unique records (no dups in data_code)
this table will look like this...
Id, data_code, Num_dups, dup1_source, dup1_date, daysbtw_Dup1_dup2, dup2_source, dup2_date, daysbtw_Dup2_dup3 ,dup3_source, dup3_date, daysbtw_Dup3_dup4 ,dup4_source, dup4_date,
I know there is no more than 4 dups of each record.
what i want from this is a table that will give me a record of how many dups for each record then all the dates that they were added and the date between each record entry.
if anyone can help it would be great .

Hey, all! Thanks for helping, here is my situation.
I have a table with about 70,000 records that have duplicate Address field values. The rest of the field values for those records are different. When I do a find duplicate querry I get the result that 17,000 records have the same address. However, when I do the append qurrey as instructed here: http://support.microsoft.com/?kbid=209183 I get a total of only 600 records in the new table. I have tried deleting all of the indexes for both the new and old table, with no luck.
I'm using Access 2000 on XP Pro.
If anyone could help with this I would greatly appreciate it!
Thanks

I have a table in a healthcare patient database that stores Admitting Number, Scan Number, Last Name, and some other fields detailing the scan. Each patient can have multiple scans and I'm trying to design a query that lists how many scans each patient has had by finding all the duplicate admitting numbers. I'm using this SQL statement:
SELECT MultScans.Admitting_Number, Count(MultScans.Admitting_Number) AS Num_Of_Scans
FROM MultScans
GROUP BY MultScans.Admitting_Number
HAVING (((Count(MultScans.Admitting_Number))>1));
which works fine but I can't figure out how to also print out the last name, scan number and the other fields in this query. If I add the field to the select part it says I can't because the expression is not part of the aggregate function and if I add the expression to the 'group by' the query runs but displays all the duplicates. Thanks for any help.

Please help. I am having difficulty understanding why a subform is showing duplicates despite using SELECT DISTINCT for its query. I have looked all over the forum but am still quite confused.
I think my database is normalised but this may be the problem and can attach it if necessary.
My query is as follows
SELECT DISTINCT StudentAndCourse.ClassID, StudentAndCourse.LevelID, StudentAndCourse.StudentID
FROM [Level] INNER JOIN (Class INNER JOIN StudentAndCourse ON Class.ClassID=StudentAndCourse.ClassID) ON Level.LevelID=StudentAndCourse.LevelID;
Any help would be most appreciated as I cannot understand what is going wrong.

Hello,
I am just wondering whether there is any way I could run a simple query that would pull all the data I need and inform me of the duplicates if there is any.
Thanks!

Hi everyone.
I have a query linking 2 tables. The idea of the query was to show our longest serving customers. The one table contains CustNo, Address details, etc and the second table contains AccNo, CurrBal, AccType, CustNo, etc etc. (note the bold fields are the primary keys). However this is bringing back results on account level rather than customer level, i.e CustNo 3 might Have AccNo xxxxxx, AccNo xxxxx1, AccNo xxxxxx2. How do I get it to show the 'oldest' account for each customer. So it will only show each customer once and that customers oldest account. Heres the SQL for the query. Hope someone can help. Thanks
SELECT DBSINV97.DateOpen, DBSINV97.AccNo, DBSINV97.CustNo, DBSINV97.PostalName, DBSINV97.CurBal, DBSINV97.AccType, DBSINV97.DateClose, DBSCUS01A.Title, DBSCUS01A.Initial, DBSCUS01A.Surname, DBSCUS01A.Street, DBSCUS01A.District, DBSCUS01A.Town, DBSCUS01A.County, DBSCUS01A.Postcode
FROM DBSINV97 INNER JOIN DBSCUS01A ON DBSINV97.CustNo = DBSCUS01A.CustNo
WHERE (((DBSINV97.DateOpen)<"2002-01-01") AND ((DBSINV97.DateClose)="1800-01-01"));

I've been researching and reading about how to eliminate duplicates in my Query, but all the suggestions don't seem to work. Here is my problem:
I want to create a Query with information from 2 Tables. Ultimately, I want my Query to be a malining list that I will be sending requests to. But, I want only the names, addesses, etc. of the people who fit certain criteria (info. stored in several different fields of the two tables). So, if a person matches two of my specified criteria, they appear twice in my query. Or if they fit all the criteria, they might appear 5 or 6 times. I want each name and address to show up once, even though the person may fit into several criteria. Does this makes sense?
I've tried typing "DISTINCT" after "SELECT" in SQL, but that didn't do anything. I've also tried changing the "Unique Values" to YES, but that didn't work either.
Sorry if it's unclear, but I am very new to Access! :(

Hello
I've created a query that finds duplicate records in a table. I've also made a form based on that query that shows some fields of the duplicate recoeds found. In that form there's also a textbox that counts the records found (using the count([field]) function). Everything works perfectly when there are duplicate records. However, when there are no duplicates , I'd like the textbox value to be 0 (it shows nothing now obviously because the query returns no records), as long as some other actions to be performed. How can I check (in the vb code or somehow else) if the query returns no records as a result ? Thanks in advance

Friends,
I have a table with 3 fields:
NAME
AMOUNT1
AMOUNT2
Field AMOUNT1 and AMOUNT 2 can have the same data and I need to run a query which will return records with similar data in both fields. Both fields are text (5 characters) and the match has to be done on the first four characters.
Please note that I have tried with a Find Duplicates query but does not seem to return all the records with showing the same data probably to the fact the the last character is different.
Any help? Thank you.

I am running a query to return records from a table. I want to eliminate records from the query if the values contained in one field are duplicated. I have tried using the DISTINCT keyword but it only works if the entire record is unique or if I was retieving just one field
Any suggestions appreciated

I am using a combo box to assign gun numbers on an employee form (frmemployees). I also have a query listing only the gun numbers that have been assigned. When I select a gun from my combo box, I what to evaluate if it is already on the gun assignment query. That way I cannot assign the same gun to two different people. I am using the before_update event to do this. The code that I am using is as follows:
Private Sub intgunNumber_BeforeUpdate(Cancel As Integer)
If DLookup([intgunNumber], "qrygunassignmentcurrent", Me.intgunNumber) = Me.intgunNumber Then
MsgBox "Item # is already listed.", vbOK, "DUPLICATE FOUND"
Cancel = True
End If
"me" represents my frmemployees form. The problem is that it's causing an event even for the numbers that aren't listed on the query. I am trying to get the evaluation correct but am having difficulties. All the fields are numeric fields. :( :mad:

I have a Duplicates Query that extract the following information from my Table
Name Surname DOB Joined
The query then extracts info such as...
Bill Smith 25:12:70 1999
Bill Smith 25:12:70 2005
Most of the time the 'Joined' field has the same year. But I need to find the ones where the year differs but the rest of the information is exactly the same. Because there is 15000 odd records to check, I thought that there would be a quicker way to check.
Could someone please assist me with this query if it is possible?
Thank you in advance.

I have the following two querys which are supposed to return only the latest Note for a Prospect.
QRYNotes
SELECT TBLNotes.ProspectID AS Expr1, Max(TBLNotes.NoteDate) AS MaxOfNoteDate
FROM TBLNotes
GROUP BY TBLNotes.ProspectID;
QRYNotes2
SELECT DISTINCT TBLProspects.CompanyName, TBLNotes.NoteID, TBLNotes.Note, TBLNotes.NoteDate
FROM (TBLProspects INNER JOIN TBLNotes ON TBLProspects.ProspectID=TBLNotes.ProspectID) INNER JOIN QRYNotes ON TBLNotes.NoteDate=QRYNotes.MaxOfNoteDate;
When I run the QRYNotes2, I get more than one record per Prospect instead of just the newest NoteDate.
What is wrong?

Hi All.
I have a db, with, amongst others, one form that I enter job details, and another form that I enter the materials for the job. These forms are linked by the ID_Number. This all works fine
I have a query that links both these forms together, so when the query is run, it shows the ID_Number of all jobs that have been done completed between dates, whether they have materials assigned to them or not.
This all works fine, but if for example, there are 10 jobs in one month and one of those jobs have more than one material booked against them, then that job number will show twice.
What I would like to do is "Hide Duplicates" on the query.
Can someone help?
Many thanks.
Frank.
