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.

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?

Hi all,
I have an append query that I run daily and want to append only records with
different OrderID.
------------------------------------------------------------------------
INSERT INTO tblConfirmSchedule ( OrderID, JobCode, JobDate, Status, [Home#],
[Work #], Ext, [Other#], Ext2 )
SELECT Orders.OrderID, [Schedule Info].JobCode, JobSchedule.JobDate,
JobSchedule.Status, CustNew.[Home#], CustNew.[Work #], CustNew.Ext,
CustNew.[Other#], CustNew.Ext2
FROM (CustNew INNER JOIN Orders ON CustNew.CustomerID=Orders.CustomerID)
INNER JOIN ([Schedule Info] INNER JOIN JobSchedule ON [Schedule
Info].JobCode=JobSchedule.Scheduled) ON Orders.OrderID=[Schedule Info].OrderID
WHERE (((JobSchedule.JobDate)>Now()+3) And
((JobSchedule.Status)="Scheduled"));
--------------------------------------------------------------------------
Any ideas?
Thanks in advance,
Emilio

I have a form which allows the user to add new records to a table. After the user had entered all the information into the form, they click a command button to add the record. In addition to adding the new record, my command button runs an query which is supposed to generate a random number between 1 & 1,000,000,000 and update the record ID field with that number.
Here is the formula I have been using in the "update To" now of my query: Int((1000000000-1+1)*Rnd()+1)
My problem is that I keep getting duplicates. You would think that the chances of getting a duplicate number would be pretty small with this large of a range, but I get a duplicate almost every time.
I have tried indexing (No duplicates) the field in the table, but that did not work. When my query generated a duplicate number, the record was just not added to the table.
I also tried a two step approach:
1-Make a table of all in use record ID numbers from my table (tblIdNo)
2-Update new record with a random number that is not in tblIdNo
This was a no-go too
How to build an update query that will update each new record added to the table with a random number between 1 & 1,000,000,000 without any duplicates? This seems like it should be so simple, and I am starting to get really frustrated.
I would prefer to accomplish this through a query/queries (if possible) rather than with 100 lines of code. This database is not for me, it's for another group, and the individuals in this group are totally freaked out by code.

I have an append query that everytime it runs it will simply duplicate the records. ex.. sample table has 11 records if you run it again the tableB will now have 22 records. I need it to only update the records, so if someone makes in change / new record in tableA it will only update the records in TableB.
I have the Primary Key set to Yes no duplicates.
TableA Primary Key is ID
TableB Primary Key is CustomerID
Thank you,
Chuck

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"));

I have a query showing duplicates, I want to hide the duplicates that have a null value in one of the rows..
Trunc_Name M_UNDERLYIN MaturityDate Duration SumOfSumOfM_VEGA Volatility

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.

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];

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.

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.

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?

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.

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).

I am trying to add calculations to queries based on columns in the query... it seems to randomly expect 'Expression' or 'Group by' as column types, and Im having to create 3 sets of queries following on from each other to de-dupe data and allow filters on calculated values.
Also I've got a function which turns a date into a quarterly cohort, e.g. Oct 2013 -> 20134. I use ot on a lot of dates. I created a VBA function, CohortQ used as follows in queries:
Cohort: IIf Year([InputDate]) < 1990 or Year([InputDate]) > 2020, 0 CohortQ([InputDate]))
In the VBA, InputDate is defined as a date
Code:
Function CohortQ(InputDate As Date) As Integer
If InputDate = 0 Then
CohortQ = 0
Exit Function
End If
[Code] .....
But when I run it on a date field, it gives me a data mismatch error. I can't step through as it's working on 600K rows.
If I put the function into the query,
Cohort: IIf Year([InputDate]) < 1990 or Year([InputDate]) > 2020, 0 Year([InputDate])*10+DatePart("q",[InputDate]))
it works.

I am looking to make an invoicing database.
I create 30 invoices a month. each client gets billed the same amount each month (for example Customer A gets billed $100 every month, Customer B gets charged $200 each month). Only two things get changed on the invoice-'Description' (for example the description would be 'services rendered for July 2014' for July invoice) and 'Invoice Date'.
Now please see the image attached, I have an append query that combines information and creates invoices for all 30 clients.
The problem is, the 'Invoice No' field in the invoice table stays empty, because I do not know how to start numbering at a specific point (for example invoice numbering should start at 14150001) and I want it to add the number (+1) automatically when this append query adds data to the invoice table.

I receive the data from engineering team lets name it as MAster database( in DB2 database - Read only ) and then i want to assign the data to each member and staus will be updated by them.So my Idea is upload the data from Engineering team (MAster database) to my (Local database), i think of using Append query if there is any changes in engineeiring data after i append the data then i can use the Update query to modify the data.
But once i assign the job to every member from my Localdatabase, i want it to stored in a data base with their name because it is a huge volume data and it will go for years.The bottleneck is If i use the Append query here, the changes from Masterdatabase to Locadatabase will not reflect in Team members database? is any solution for this or i have to use the Update query in Localdatabase and also in Team memers database?

I am trying to create a query to append new records from my NEW database into my old excel database.....
The old DB has 4-5 extra tabs that the NEW database does not have so when I append, in those extra columns the new database will just have blank records since the column doesn't exist.
Usually I do a append query in design view. but sometimes it gets funny because it creates duplicates...
How would I go about it, so its quicker and persistent like creating a macro excel.

I am creating a database for users that no nothing about access nor do they want to learn. So the database needs to be as simple as possible.
This being the case I would like to avoid users from creating/editing querys.
I would like to have a form that would run the append query. The query would have a date column and a status column that the query would filter.
The query would have a criteria for status that would equal to "BACKED OUT" and the date would need to link to the two text fields on the form. My problem is writing the VBA code to make the query append in the background.
For sake of argument:
Query = qryappend
Form = frmappend
Table = tblappend

I want an append query to create a new record in a table and populate that record with fields from a form. Some of these fields are free text, others are from combo boxes.The append query adds vastly too many records (albeit all populated with precisely the same information) - and the number it adds seems to depend on which combo box options I choose.
I have a similar append query which pulls information from earlier records in the table, and combines that with free text and combo boxes on a near-identical form, which works fine and always just adds one row.

I am trying to create a table from a form. The form has several fields but I need to take the value from 4 separate combo boxes ([cr] +[br] +[tr] and add them, then add the value from one more combo box [inc] to be my beginning value in a table.
I then need to add the last value [inc] to the total and that become the next line in the table. I would the like to add this value [inc] an infinite number of times until it reaches a max number.
The scenario would be something like this
cr=3 br=2 tr=3 inc=1.5
So the first total would be 9.5. Then every row after that would be plus 1.5
11
12.5
14
15.5
17
and so on.
This would be a temp table that I would run a query on to let an operator know lengths they can choose from in a combo box. I don't know if this is even possible.
