Queries :: Updating First Row Of Duplicate Records
Jan 30, 2014
I have two tables -say Table A and Table B.
Table A Table B
ID userno ticketno Status userno ticketno Status
1 1211 YAB 1211 YAB LIVE
2 1211 YAB 1232 ACE LIVE
3 1232 ACE 1232 AAT INVALID
4 1232 ACE
5 1232 ACE
6 1232 AAT
I am trying to write an update query in MS Access that will update only the first record of any custno with the status so that my final table A looks like this:
Table A
ID userno ticketno Status
1 1211 YAB LIVE
2 1211 YAB
3 1232 ACE LIVE
4 1232 ACE
5 1232 ACE
6 1232 AAT INVALID
How to write the query.

In my simple database (attached), I need to mass duplicate Tasks and their Notes.
I have three tables: tbTasks (PK: Task_ID), tbNotes (PK: Note_ID), jtbTaskNotes (FKs: Task_ID and Note_ID). jtbTaskNotes is my many-to-many junction table that ties Tasks to Notes.
The main form (fmTasks), bound to tbTasks, has a subform (sbfm_TaskNotes) that displays notes associated with each Task. On themain form,you select which Tasks you want duplicated via a checkbox. The append query (quCopyTasks) will duplicate all tasks that have the checkbox checked. All good there. However, I can't figure out how to also duplicate each task's Notes.
I found Allen Browne's solution [URL] ....., but that only handles duplication of one record at a time, whereas I need to duplicate many records at a time (sometimes 10+ records). How do I go about duplicating multiple Tasks and their associated Notes?
Before you ask "why are you duplicating records?": There are times when tasks need to be re-accomplished and therefore need to have a new record. It's easier to duplicate records than it is to hand-jam everything again.

I thought I had just about finished my DB but now Ive printed out and checked my reports I notice I have several records in different types of reports showing duplicate records. Iv'e gone back over the queries and there are one or two duplicates in several of my queries that I did not notice before because there are are only the odd one or two. No matter what I do I can't stop this happening. I think it must be something to do with the dates in my payment table. PaymentID is key field - foreign key is MemberID. One member can have several paymentID's a new one every year when membership renewed. The problem seems to be when the member has two payment dates in the same year. This shouldn't be anyway but the database has not been used properly with entry dates missing, written over of wrong dates etc. Ive tried to correct this but do not want to tamper with past payment date records. I already have 'select distinct' in my queries and have tried 'distinct row' which seems to return even more duplicate records. Im pulling my hair out over this there must be a way to return the records from members showing just 1 only of their very latest payment record/date. Im using this expression in the query.
LastPaid: (SELECT MAX(PaymentDate) FROM S_Payments_Table WHERE S_Payments_Table.MemberID =S_Members_Table.MemberID)

I'm having a problem removing duplicate records from a table. It should be easy but I can't suss it.This is an example of the data in my table:
Code:
RefDateStatus
113007111/06/2015Do Not Pay
114454306/07/2015Do Not Pay
115760714/05/2015Do Not Pay
116520705/05/2015Do Not Pay
117670108/05/2015Do Not Pay
118036218/05/2015Do Not Pay
118517015/05/2015Do Not Pay
178734020/07/2015Do Not Pay
182809915/07/2015Do Not Pay
184226010/07/2015Payment Due
184226022/07/2015Payment Query
As you can see, there are 11 records here but the last two records have the same reference number. I need my query to show the first 9 records + the record from the bottom two with the latest date (22/07/2015).

I have a table and there are so called duplicate records (not entirely duplicate because there is field with the date of creation and other differences in a few fields, but from my point of view they are duplicates.). I d like to make a query which shows me only the newest record in case of duplicity.

when running the attached report I am getting duplicate records. If using the protocol specified tc02026 there should be 8 records total. When running the report it pulls from both queries which have select criteria. How do I limit the report to only give me the 8 records and eliminate the duplicates? When I run each query it only gives me the 8 records I am looking for. Each Sample# in the report is a unique number(to help see the replicates).
Thanks

Im trying to write a query that shows all the container movements. Yet when I run the query qryFullHistory I get a duplicate value for container Off Island. Ive tried adding some criteria that says that the DateRequested has to be between the ImportDate and ExportDate but that doesnt seem to work. There are duplicate entries for container Off Island in tblContainerDetails as the same container has arrived and left and then returned on another voyage. Yet there is no entry for the second voyage in the tblMEMRContainer.
A brief description of the tables is:
tblMEMR Movement requests details
tblMEMRContainers the containers that were moved on the movement request. There can be more than 1 container for each request.
tblContainerDetails details and dates for the container when it arrived and when it left
There are other tables but these are the 3 that are used in the query.

Why I am getting duplicate results for some of my records in a query. I have unique values set to Yes. I have also validated that the tables I am using don't have duplicate data. SQL is below.
SELECT DISTINCT [tbl_Rewards Activity Report - By Member Number].[Member Number],
[tbl_Rewards Activity Report - By Member Number].[Last Four],
[tbl_Rewards Activity Report - By Member Number].[BAL ID],
[tbl_Rewards Activity Report - By Member Number].[Primary Name],

I have this small database, I would like to have your support to setup this query "QryResults" in order to remove the duplicate records, I can't find a way to get shown only true records, for some reason I'm getting duplicate rows and fake values, the query is calculating operations from two different queries and a table.

I'm trying to duplicate the records in a subform to a new form but keep getting a too few parameters error.
Code:
strSql = "INSERT INTO [OrderDetailT] ( OrderID, ProductID, Quantity, DiscountPercentage ) " & _
"SELECT " & lngID & " As NewOrderID, ProductID, Quantity, DiscountPercentage " & _
"FROM [OrderDetailT] WHERE OrderNumber = " & Me.OrderNumber & ";"
The debug.print comes out as below:
INSERT INTO [OrderDetailT] ( OrderID, ProductID, Quantity, DiscountPercentage ) SELECT 49 As NewOrderID, ProductID, Quantity, DiscountPercentage FROM [OrderDetailT] WHERE OrderT!OrderNumber = 11;

I have 10 tables linked in one query. 9 tables are linked to one main table (one to many relationship).I want to get rid of duplicate records that show different data in multiple columns. I want only one record of this but retain with different data under different columns to be separated by commas. For example: I want this...

I am using two tables to find the data (main - "employee tbl" and "courses tbl")I have been trying to follow Allen Browne`s method, but I`m unsuccessful. This is the code I've put in SQL of this query:
Quote:
SELECT [Employee #], ConcatRelated("[Courses]", "[Courses tbl]", "[Employee #] =" & [Employee #]) from [Employee Tbl]
SELECT [Employee #], ConcatRelated("[Start Date]", "[Courses tbl]", "[Employee #] =" & [Employee #]) from [Employee Tbl]
SELECT [Employee #], ConcatRelated("[Completion Date]", "[Courses tbl]", "[Employee #] =" & [Employee #]) from [Employee Tbl];
However, I am prompt with "Syntax error in query expression".It also prompts another expression to be in error when I include the above but it runs okay when I don't do the above:
Quote:
WHERE (([Employee Tbl].[Employee #]) Like [Enter Employee ID or leave blank for ALL employees] & "*")
I placed the following in VBA module:
Code:
Public Function ConcatRelated(strField As String, _
strTable As String, _
Optional strWhere As String, _
Optional strOrderBy As String, _

I have a table with more than 60 fields and need to update it with records from another Access file with a table with an identical data structure.
Is it better to run an update query or an append query (i would have to delete the original records in the target table first) or a union query?
If I run an update query I will have to manually add each field to the query.
The update query will not add 'new' records. If I run an append it is quicker because I can use the * to match all fields, but i will have to delete the 'old' records first, as both tables use autonumber for the PK so the PK ID will be the same in each table (will get a key violation error).
If I import the 'new' table and run a union query it will match the fields and add the new records, but then i will have to create new table from that query.

I have a database with an import process which normalises incoming data and appends to various tables. No issues with that. I also have a function within that process which counts the number of new entries for a summary popup when the process has completed.This works by querying the staging table, prior to the append, into a recordset and using the .RecordCount to increment the count (multiple files can be imported at once so this effectively provides a running count, per file, to give a total for the whole import)
I thought it was working fine but this morning I noticed that the count which appeared on the popup was 1 greater than the number of actual new records. I checked the source files and noticed that, for whatever reason, there was a duplicate entry in there. So I presume that's why the count was out by 1.
There's no integrity issue in the main tables as the composite primary keys ensure that duplication shouldn't be a problem. Indeed, the record in question, duplicated in the source, appears only once in the main table post-import. So not too worried about that.
However, I need the count in the popup to be accurate (it tells the users how many new entries require further investugation). And what's puzzling me is that I use DISTINCT in the query, which I would have thought should eliminate any potential dupes in the recordset and thus provide the correct count. It seems it doesn't?
Code:
Public lngNewBalancesTBI As Long ' Defined in a separate module...
-------
Dim dbs As Database
Dim rst As Recordset
Dim strSQL As String
[code]....
Why the dupe, which is still present in the staging table, also makes it over to the recordset, even though I'm using DISTINCT?

I have a table with duplicate records (which is ok) and I want to return distinct data for each client.
It works fine when there is only two fields returned however, when I add a third field to the query it no longer returns only the Distinct records - I am getting Duplicates returned.
I.E
SELECT DISTINCT tblClient.ClientNo, tblClient.Name
FROM tblClient
Works fine with only the Distinct records for each client returned
However
SELECT DISTINCT tblClient.ClientNo, tblClient.Name, tblClient.Address, tblClient.OrderValue
FROM tblClient
Now returns Duplicates!
Is there a limit to the number of fields to be returned using DISTINCT or what else could be the problem? Should I be doing this some other way?

I'll first of all explain the purpose of the query. I've built a database to record the admission details of patients admitted to hospital. Amongst other things, the database captures date/time of admission and date/time of discharge.
The query I am building needs to show patients with multiple admissions, and in particular, the number of days that have elapsed since they were last discharged. Within my query is the following subquery that I had written to show this aspect of it:
(SELECT TOP 1 Dupe.[Discharge Date]
FROM [Inpatient Database] AS Dupe
WHERE Dupe.[CHI Number] = [Inpatient Database].[CHI Number]
AND Dupe.[Discharge Date] <= [Inpatient Database].[Admission Date]) AS [Previous Discharge],
Note: "CHI Number" is a unique reference number assigned to every patient.
I then display in a column [Admission Date] - [Previous Discharge].
This works fine where a patient only has one previous admission. However, where a patient has multiple admission, the subquery always returns that patient's first discharge date instead of their most recent discharge date (because I have used the "TOP 1" predicate). It seems that it should be straightforward enough, however I can't seem to work around it. Anything I try results in errors, and so I keep defaulting back to my "TOP 1" solution.
i.e. What I want it to show is:
Name.......Admission Date...Discharge Date.... Previous Discharge... Days Between Admissions
Joe Bloggs ..01/01/2014 .......10/01/2014
Joe Bloggs ..15/01/2014 .......20/01/2014 .......10/01/2014 ..............5
Joe Bloggs ..27/01/2014 .......01/02/2014 ........20/01/2014 .............7
However, what it actually shows is:
Name ......Admission Date ...Discharge Date ...Previous Discharge ...Days Between Admissions
Joe Bloggs ..01/01/2014 ......10/01/2014
Joe Bloggs ..15/01/2014 ......20/01/2014 ........10/01/2014 .............5
Joe Bloggs ..27/01/2014 ......01/02/2014 ........10/01/2014 .............17

Good morning to you all.
I have a problem that I thought would be quite simple......
But 3 days later I am still trying.
I have a form which populates a table by one set of users (Simple enough) they can only add records.
I also have another set of users who want to access that table through a similar form but with a couple of added fields.
They will not be able to change anything only add their comments to what they see in the new fields supplied. Once this has been done it cannot be edited ever.
So I made a "Make Table Query" and added 2 new fields to that, so when I clicked on the query it came me the last update from the previous table. Problem was everything that was added in the extra fields were deleted!!!!
I would like to update the 2nd table with items that have been newly added to the first table, leaving all the items on the second table the way they were!!!!!!!
Anyone got any ideas please

I'm running an update query that's based on a select query (that runs some calculations). The update query is updating ALL the rows that should be updated with the information in the select query with data from the final row in the select query, and not on a per ID basis as I think I have it set-up to do. The data looks correct in the update query, but again it's not coming out right.
Here's the SQL for what I've written so far:
UPDATE [Customer_Data Query], Customer_Data INNER JOIN Baseline ON Customer_Data.ID = Baseline.ID SET Baseline.[Unit Hours] = [Customer_Data]![Dur_Days]*[Customer_Data]![Dur_Hours]*[Customer_Data]![Number_Units], Baseline.Availability = [Customer_Data]![Perceived_Avail], Baseline.[Hours Available] = [Customer_Data]![Dur_Days]*[Customer_Data]![Dur_Hours]*[Customer_Data]![Number_Units]*[Customer_Data]![Perceived_Avail],
[Code] ....
I've also tried to force the update to the proper row by adding a criteria based on ID.
Select query, here it is:
SELECT Customer_Data.ID, Customer_Data.Data_Set_Version, Customer_Data.Number_Units, Customer_Data.Perceived_Avail, Customer_Data.MTTR_MTBF, Customer_Data.MT_TR_OR_BF_Hours, Customer_Data.Utilization, Customer_Data.Percent_Scheduled, Customer_Data.Sched_Percent_of_PM, Customer_Data.Sched_PM_Duration, Customer_Data.Sched_CBM_Duration, Customer_Data.Sched_CBM_From_PM, Customer_Data.React_Detect, Customer_Data.React_Rework, Customer_Data.React_False_Alarms,
[Code] ....

I'm trying to determine the SQL to return only those records in a table which have duplicate values in each of two fields, but different values in a third field. Here's an example:
Code:
AcctNum FoodType FoodClass
------- -------- ---------
A123 Apple Fruit
A123 Apple Fruit
A123 Grape Fruit
A456 Potato Vegetable
A456 Potato Perishable
A789 Carrot Vegetable
A001 Banana Fruit
For the above table, I'm trying to return records which have multiple entries for AcctNum + FoodType, but DIFFERENT values for FoodClass. So for the above table, the query would return:
Code:
AcctNum FoodType FoodClass
------- -------- ---------
A456 Potato Vegetable
A456 Potato Perishable
It returns these two records because there is more than one record with for the AcctNum + FoodType (i.e. 'A456' + 'Potato'), but DIFFERENT values for FoodClass (i.e. one record has 'Vegetable' while the other has 'Perishable').

I'm using an UPDATE query to update records in one table (tblMain) from another table (tblTemp)
Here is my SQL :
Quote:
UPDATE [tblMain]
INNER JOIN [tblTemp] ON [tblMain].[MainField1] = [tblTemp].[TempField1]
SET [tblMain].[MainField2] = [tblTemp].[TempField2];
I only want to update the records in tblMain which have a corresponding record in tblTemp (linked by MainField1 / TempField1)
If any record doesn't appear in tblTemp, I want tblMain to retain the existing value for that record.
However, it appears that in such situations, the record in tblMain has it's MainField2 value set to null / ZLS.
I've tried using LEFT JOIN and RIGHT JOIN and also tried WHERE clauses but the result is the same every time.

I have an Access 2007 application that has a Parts Table that contains a list of automotive parts.I have attached a screen shot (parts.jpg) showing the structure.I have another table called Web_Parts that has exactly the same structure as Parts. The Web_Parts table gets its data from a CSV import that I do that is data extracted from an MySQL database used by an eCommerce website.
You will notice that there is a field called "Web_Product_Id" (number). This is the unique ID for each of the products that I have exported from the Web shop system. I need to regularly (probably every couple of weeks), export out of the web shop system and import into the Access environment.
Due to the fact that the data in the web shop system may change (pricing, description, add new items, delete new items etc), I need to find a way that I can simply update any existing records in the Parts table with any new information contained in the Web_Parts table......

I have built a qry that initially shows the correct information. For example.
tblContent has 289 records with a Type = Class.
I built a Query to select from tblContent Type = Class and I get 289 records. I add additional criteria of Progress <>"Not Scheduled", I then get 206 records. I then add additional criteria Last Name <>"Demo" And <>"Care" And <>"Support". This brings up 200 records, but the query appears to duplicate each record 3 times. I do not have 3 of the same types of records.
The SQL Statement is below
SELECT tblProfile.LoginName, tblProfile.FirstName, tblProfile.LastName, tblProfile.Organization, tblProfile.CostCenter, tblContent.Title, tblContent.Type, tblContent.Code, tblContent.[Date Assigned], tblContent.[Date Started], tblContent.[Last Accessed], tblContent.Progress, tblContent.[Date Completed]
FROM tblProfile INNER JOIN tblContent ON tblProfile.LoginName = tblContent.LoginName
WHERE (((tblProfile.LastName)<>"Demo" And (tblProfile.LastName)<>"Care" And (tblProfile.LastName)<>"Support") AND ((tblContent.Type)="Class") AND ((tblContent.Progress)<>"Not Scheduled"));
The qry is named qryPhysical Class. I have provided the link to view the database. Can you help me?
