Queries :: Append Query With Unique Duplicates

Sep 11, 2013

I'm attempting to create an append query that will add new records only if there isn't an equivalent record already existing. Typically I would add the existing table to the query, and only add new records if the same do not exist. In this case, the table is maintaining records over time (start date and end date).

I have 4 tables:

[t_employees]
employee_ID
employee_name

[t_cities]
city_ID
citiy_name

[t_city_assignment]
city_assignment_ID
start_date
end_date
employee_ID
city_ID

[t_temp_employees]
effective_date
employee_ID
city_ID

I'm checking if [t_temp_employees].[effective_date] <> [t_city_assignment].[start_date]. However, if the employee has historical entries it will still add a record (in fact, it'll add multiple records).

How can I append a new record only if one for the same time period does not exist?

Queries :: Unique Query Is Giving Duplicates

Aug 4, 2015

I have a unique query which lists all the films that we are screening over the next 3 months. I have added a COUNT field so that I can see how many of each films we are screening.

The problem is that i get duplicates of some films - and this may be because we may hold several copies of some films. I have attached two images which might explain this better!

What I could do with is knowing how to make it so that i get a list of films booked and how many of each, regardless of which copy of the film is used.

The SQL is:

Code:
SELECT DISTINCTROW dbo_Films.[film name], Count(dbo_Films.[film name]) AS [CountOffilm name]
FROM ((dbo_Films INNER JOIN dbo_filmCopies ON dbo_Films.ID = dbo_filmCopies.tblFilms_ID) INNER JOIN dbo_EventsFlicks ON dbo_filmCopies.ID = dbo_EventsFlicks.filmCopyID) INNER JOIN dbo_Venues ON dbo_EventsFlicks.venueID = dbo_Venues.ID
WHERE (((dbo_EventsFlicks.datefield)>=#8/1/2015# And (dbo_EventsFlicks.datefield)<#1/1/2016#))
GROUP BY dbo_Films.[film name], dbo_Venues.southhub, dbo_Venues.northhub, dbo_Films.Specilaised
ORDER BY dbo_Films.[film name];

Queries :: Using Append Query But Not Adding Duplicates?

Jul 30, 2013

I would like to use an append query that appends data from a union query into a table, but doesn't add duplicates based on a certain field.

I have been trying to use this code, but it doesnt seem to work.

INSERT INTO [Cotton13/14]
SELECT DISTINCT [Contracted Farmers].*
FROM [Contracted Farmers]
WHERE NOT (SELECT * FROM [Cotton13/14] FROM [Cotton13/14] AS [Cotton13/14] WHERE [Cotton13/14].[OF Codec] = [Contracted Farmers].[OF Codec])

Cotton13/14 is the table I want to append to and Contracted Farmers is the union query. However the code is giving me an error.

Queries :: Append Query - Unique Records To Create Relationship

Mar 22, 2015

I have created a linked Excel table in Access 2010 called 'tblExcelLinked' and I have a form called 'ASB Log Form' for the purposes of presenting the data in a more readable manner that is easier to view, plus link other fields of data that are not directly related to the 'tblExcelLinked'.

Because there is no unique ID in the 'tblExcelLinked' to create a relationship, I have created a table called 'tblASB', which allows me to add other table data linked from same d/b.

I now want to update the 'tblASB' with data from the 'tblExcelLinked', but only append new records from 'tblExcelLinked', but my inadequate append query is duplicating the records each time I run it, rather than just adding the new ones.

Once sorted my next challenge is a macro so that this runs automatically rather than being manually triggered.

Queries :: Delete Duplicates Retain Unique Records

Aug 13, 2013

I have a table that has multiple records (count >1). I used the find duplicate records and then made it a delete query, however, this resulted in deleting all the records that had count >1. I need to retain distinct record, and delete the extra records. Using select distinct.. I do not want to use VBA to achieve this, but at the same time be able to incorporate the steps in a module that would execute the queries in a sequential order and achieve the same results.

Queries :: Prevent Duplicates With Unique Field Of Joined Fields

Nov 2, 2014

I have a client database that has recently had multiple duplicate entries. I need to reduce or negate this erroneous activity. I have a client table where I record amongst others, the following;

key
[christian_name]
[family_name]
[dob]
......

I believe that to prevent duplicate entrie via form I have created an additional field called "unique" given it as a unique index which I want to have populated with the joined fields first_name & last_name & dob (IE johndoe01/01/90), and then as user enters a new client it wont allow a duplicate.

However I need to fill all the existing customers (3600+) with the relevant joined existing data. If I create an expression I can cajoin the fields in a select query but when I try to make an update query the same syntax comes up with empty fields.

select query sql that worked to show field ...

SELECT divers.christian_name, divers.family_name, divers.dob, [christian_name] & [family_name] & [dob] AS Expr1
FROM divers;

update query that was empty ..

UPDATE divers SET divers.[unique] = [christian_name] & [family_name] & [dob];

How To Avoid Duplicates In Append Query

Jun 13, 2005

Hi all,
I have an append query that I run daily and want to append only records with
different OrderID.
------------------------------------------------------------------------

Counting Unique ID's Without Duplicates

Jun 29, 2006

Hi,

I have a problem with getting the right result with a query.

To this topic I attached a part of my database including 2 queries. The queries are almost the same, except the first field. In query 1 is the total 'Group By' and in query 2 'Count'.The other fields are parameters, which are the same in both queries.

My problem:
If I run query 1 then the result is 31 rows with unique ID's. When I run query 2 the result is 35, because the query counts 4 duplicates.

The correct result I want is 31. That means count the unique ID's. I am able to show the ID's with query 1, but I am not able to count them correctly. I tried to add 'DISTINCT' in SQL view but that didn't help.
Also other solutions written in this forum didn't work.

Thank you if someone (with more query/SQL experience) is able to help me... :o

Unique Identifier - Append Primary Key Record

Dec 9, 2014

I have a database in Excel that contains farmers who can be identified by a Unique identifier: MZ-01-0001. The registration details for these farmers are not always up to date. Now when I try to append the data for the farmer with MZ-01-0001; with the primary key set on the Unique identifier, Access does not want to do it since there is already a record in the system. When I remove the primary key it doubles the record, which is also not what I want. So I am wondering what I need to do to append the record while keeping the primary key intact.

Modules & VBA :: Append Data From One Table To Another - Skipping Duplicates

Mar 12, 2015

I have two tables, tblCandidate and tblNewHire. I am trying to transfer candidates to tblNewHire based on the date they are hired. However, I would like the database to skip any records that are already in tblNewHire, just in case someone inadvertently puts in the wrong date when running the query.

I created an append query (SQL below) but this enters the data regardless of duplication. I need to be able to check both SSN and LastName against the new table and can't set either one to be unique values as it's possible there could be two candidates with the same last name.

Any way to do this by creating a recordset and looping through to check for dupes.

INSERT INTO tblNewHire ( SSN, FirstName, MiddleName, LastName, Phone, Email, EOD, HiringMechanism )
SELECT tblCandidate.SSN, tblCandidate.FirstName, tblCandidate.MiddleName, tblCandidate.LastName, tblCandidate.Phone, tblCandidate.Email, tblCandidateTracking.ActionDate, tblCandidateTracking.HireMechanism
FROM tblCandidate INNER JOIN tblCandidateTracking ON tblCandidate.SSN = tblCandidateTracking.SSN
WHERE (((tblCandidateTracking.ActionDate)=[forms]![frmNewHireMain]![txtEODDate]) AND ((tblCandidateTracking.LastAction)="EOD"));

Queries :: Hide Duplicates From Query?

Queries :: Amend SQL For Find Duplicates Query

Oct 23, 2014

I have a find duplicates query with the following SQL:

Code:
SELECT tblData.Vendor, tblData.[Loccurramount EUE], tblData.Last4, tblData.ID, tblData.Line, tblData.CoCd, tblData.[Document record number], tblData.PurchDoc, tblData.Reference, tblData.Curr, tblData.[Entry dte], tblData.Status, tblData.Version, tblData.Outcome
FROM tblData
WHERE (((tblData.Vendor) In (SELECT [Vendor] FROM [tblData] As Tmp GROUP BY [Vendor],[Loccurramount EUE],[Last4] HAVING Count(*)>1 And [Loccurramount EUE] = [tblData].[Loccurramount EUE] And [Last4] = [tblData].[Last4])))
ORDER BY tblData.Vendor, tblData.[Loccurramount EUE], tblData.Last4;

This works fine however I want to add another clause to the WHERE and I'm not sure how. At the moment the query highlights duplicates where the Vendor, Loccurramount EUE and Last4 match. I want to further restrict it so that it only finds duplicates where the Vendor, Loccurramount EUE and Last4 match BUT the number shown in version Does Not Match

So if two records have the same details for Vendor, Loccurramount EUE and Last4 and also have the same Version number then they don't show in the result.

Queries :: Unique Record Table Query

Oct 22, 2013

I am using a software drawing program that intelligently link information from a drawing to a database and vice versa. I have many tables and queries that I have created over time that enable auto populating of tables, creation of tables and so on. All of which enable me with tabular documents for ordering purposes.

The problem I currently have is: - I want to create a table that looks at an existing table, analysis various fields for duplicate information and then adds one record to a new table. This is to enable me to create a spares list based on the entire list.

I have a full valve list with various items, some duplicates some not. I am required to produce a spares list that considers only one of each type.

Queries :: Wizard To Create A Find Duplicates Query

May 29, 2014

I used the wizard to create a find duplicates query. I know for a fact that 15 records are duplicates. I'm getting over 300 records. When I dumped the data into Excel and did a pivot table to count the number of records by account number only 15 had a total count of 2. All others only had 1. Why are the ones with no duplicates showing? I just want to see the 15.

Queries :: Select Query With Joins Returning Duplicates

Sep 18, 2014

I am building a select query which is grabbing data from multiple tables with items being linked by a unique field "Certificate_ID".

I have created joins between table A and Table B, and Table A and Table C, linking both by Certificate_ID

All have the join property set to select all Records from table A, but only those from Table B and Table C where the joined fields are equal.

Table A has 5000 records. Am I correct to assume that my query should only return a max of 5000 records as well? When I select Certificate_ID from A and another column from B it only gives me the 5000 unique records. When I add in a column from Table C it is however returning something like 7500 records, with several being duplicates with the same data in every column.

Why it is choosing to duplicate records and give me more than I want. I am sure I am overlooking something simple.

Queries :: Access 2007 / Query Count Of Unique IDs

Jan 16, 2014

I have a basic query off a currency table :

Quote:

SELECT tblCurrencies.CcyID, tblCurrencies.Ccy
FROM tblCurrencies
ORDER BY tblCurrencies.Ccy;

Now - I have a separate table of balances, which is linked to the currency table by the same CcyID, and which also has identifiers to link it to other tables (e.g. AccountID)

As part of the above query, I want to return the count of unique AccountID's in the balance table for each currency. So in other words, I want to know, for each currency, how many unique accounts exist?

Each AccountID could appear one or more times in the balance table (one-to-many relationship), so I only want to count the number of unique ID's.

So I started with the following :

Quote:

SELECT tblCurrencies.CcyID, tblCurrencies.Ccy, Count(tblBalances.AccountID) AS NoOfAccounts
FROM tblCurrencies INNER JOIN tblBalances ON tblCurrencies.CcyID = tblBalances.CcyID
GROUP BY tblCurrencies.CcyID, tblCurrencies.Ccy
ORDER BY tblCurrencies.Ccy;

But this just gives the number of AccountID's per currency (regardless of duplication within them)

I found this article which informs me that a Count(Distinct) query won't work in Access and to use subqueries instead.

Queries :: Manifest - Query A List And Then Show Only Unique Values

Oct 1, 2013

One Manifest can have many line items. One line item can only have 1 designation. Each manifest may have many line item with same designations.

For example:
Manifest #0001
Line Item 1: N
Line Item 2: H
Line Item 3: U
Line Item 4: N
Line Item 5: P
Line Item 6: H

Table set-up
CurrentCY
CurrentCYIDPK
WasteCategoryIDFK
LineItemInformation [Line Item 1, Line Item 2, etc]
ManifestDataIDFK

ManifestData
ManifestDataIDPK
ManifestNumber [0001]

WasteCategory
WasteCategoryIDPK
WasteCategory [H, N, U, etc]

I'd like to query the line items for each manifest so the end result has the manifest number (Manifest #0001) in a field and the designations (N, H, P, U) in fields on a report.

Queries :: Opening Design View Of Append Query Without Timing Out Source Query

Mar 4, 2015

In some cases I create pass-through queries and use these in an Append or Make-table query to bring data locally.

All is well and fine until source data changes and the pass-through query runs too long and times out.

If needed, I can extend the timeout value in the Parameters of the pass-through query no problem, but when I try to open the Append or Make-table query in Design view to do the same, the pass-through query is first triggered and then throws the timeout, and I cannot access the Design view of the Append or Make-table

Is there a way to open an Append or Make-table query in Design view without invoking the source query?

Queries :: Find A Way For Access To Find Unique Dates And Unique Names?

Aug 1, 2014

I have been working on a simple data base for some time now (beginner level) and am still trying to improve it. I would like to do something but before that I would like to have your opinion to know if it is even possible?I have a query QryMainReport:

Start Date/Time
End Date/Time
Employee

At the moment this is what the format of my report looks like (I removed other unnecessary fields):

StartTime----------EndTime---------------Employee
12/06/2014 01:00--12/06/2014 03:00------John Smith
12/06/2014 04:00--12/06/2014 06:00------Jane Doe
13/06/2014 02:00--13/06/2014 05:00------John Smith
13/06/2014 08:00--13/06/2014 08:00------Jane Doe

I would like to do as a report. (Dates would always be from Sunday to Saturday). I am not sure it is possible to do that. I suppose first it would mean:I would have to do a query to separate the times from the dates?I would have to find a way for Access to find the unique dates and unique names?Does it mean I have to use cross tab queries?

Queries :: Key Violations With Append Query

Feb 14, 2014

I am having fun with key violations and cant seem to find out why?

I basically am deleting a Job but when i delete it i want to archive it hence the 'Archive' query and the History Tables.

It seems to be pasting everything in fine apart from the 'EmpJobHistory' Table?

I am getting the usual message "Key violations"?

I think i need the intermediate 'EmpJobHistory' Table because there will be Employees that are related to many Jobs and vice versa.

Queries :: Append Query Where A Condition Has To Be Met

Feb 26, 2014

I am trying to copy notes from one table to another table where a condition has to be met and I can't figure out how to do that in an APPEND query.

Each record has a unique number that comes into my Initial Table in my Access database from a construction program I download. In this particular table both the [DNJTNo] and [DNVersionNmbr] fields can have duplicate numbers. However, when I run the query I want it to add a record to the second table only after the query checks that the [DNJTNo] in combination with the [DNVersionNmbr], is not already in the table. If it is, I do NOT want it appended to the second table. (I have attached a picture of the query in APPEND design stage).
