Duplicates Query

Nov 24, 2004

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

Find Duplicates Different Than Duplicates Deleted

Dec 8, 2005

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

Will

Query Help, Duplicates

Aug 23, 2005

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 With This Query On Duplicates

Apr 4, 2006

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.

Duplicates In Query

Mar 25, 2008

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"));

Duplicates In Query

Mar 26, 2008

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! :(

Duplicates Query

Jan 9, 2006

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

Duplicates In Table/Query

Aug 1, 2007

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:

Sorting Further From A Duplicates Query

May 13, 2005

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.

Query Creating Duplicates

Nov 25, 2005

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?

Hide Duplicates Within Query

Jul 31, 2006

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.

Query To Show Non-duplicates

Apr 4, 2007

I have a query that includes the following fields

Year
EventNumber
CorrectiveActionNumber
ResponsibleGroup
Committment

Each event will have multiple corrective actions. For each corrective action assigned to a group, the "committment" is also assigned to them, but I also have to assigned a committment to our group (SRG). So this makes the query results show two records for each corrective action, one with the group assigned committment and one for my groups committment. I need a query that will show corrective actions that have the group committment assigned but not a corresponding SRG committment assigned. However since my query results in two separate records, I am unsure how to do this.

Any suggestions?

Thanks,
Jim

Query To Find Duplicates

Jun 15, 2007

Hi,

Our Contacts database has around 4000 individual contacts (and growing), which have been pulled together from four or five seperately maintained databases. As such there are bound to be duplicate records.

What would be a good way of querying the database to find duplicate entries (i.e. entries where the first name and surname are the same)? Short of putting everything in alphabetical order and manually scanning them to see if there are two names the same next to each other I don't know of a way to do it. Also, the manually-scanning method won't work if the names are spelled a little differently (Davies and Davis).

Any ideas?

Update Query - Getting Rid Of Duplicates.

Nov 4, 2007

Hey All

I have 2 tables - A and B

I am assigning trade ID from A to B, where they have several common fields.
Two conditions are needed.
a) Only update records where B doesn't have trade ID yet. (done)
b) Do not update records with a Trade ID , if such id is in a a Table B.

not sure how to do the second one; would making Trade ID - primary key help ?

here is the text --

UPDATE tbl_eblotter_feed INNER JOIN tbl_broker_1 ON (tbl_eblotter_feed.nm_brokers = tbl_broker_1.Broker_ID) AND (tbl_eblotter_feed.CUSIP = tbl_broker_1.CUSIP) AND (tbl_eblotter_feed.SPN = tbl_broker_1.spn_cparty) AND (tbl_eblotter_feed.dt_mat = tbl_broker_1.dt_mat) AND (tbl_eblotter_feed.amt_notional = tbl_broker_1.amt_notional) SET tbl_broker_1.M3_ID = [tbl_eblotter_Feed].[M3_Id], tbl_broker_1.Desk = [tbl_eblotter_Feed].[Desk]
WHERE (((tbl_broker_1.M3_ID) Is Null));

Find Duplicates Query

Jan 4, 2008

I know I have duplicate records in a table and therefore I used the "Find duplicates Query Wizard" to identify the duplicates.

I am positive - there are duplicates and the query does not perform the way it should be.

Any suggestion will be appreciated.

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

Query Three Tables Causes Duplicates

Jan 7, 2015

I have a report to run that gathers info from three tables. If I make individual queries to get the information I need the three queries gather the correct information. If I make one query it makes duplicates. If I combine the three queries that work the main query mixes up the information and duplicates it. How do you make a query that gets information from three tables and not have it be garbled?

Duplicates In A Form But Not The Query

Apr 9, 2013

I have a form that is pulling data from a previous days transactions but most (not all) transactions are duplicated.

I created this form a couple of years ago and have not modified it for about 3 months and nobody else has made any changes. When I look at the query that the form is pulling nothing is duplicated. When the Recordset type is Dynaset (Inconsistent Updates) I get 94 records, when I change it to Dynaset, then I get the correct count of records of 80.

Deleting Duplicates Query.. With A Twist

Jun 17, 2005

Hi,

Been reading the forums for a while now. Thanks to all you knowledgable people out there! Been a huge help in learning this program.

Here's a question that stumped me...

I have a table that is about 90,600 entries long with 4 fields per record.

Now here's the issue:

Approximately 25,000 of these entries are duplicates - based upon TWO of the fields.

SO we have:

Field1 Field2 Field3 EntryDateField

if Field1 and Field2 Match, I want to delete the record that has the OLDER entry date.

any ideas how I might accomplish this?

Thanks!!!
