Find ONLY Latest Entry For Records By Type And Position
Jul 4, 2013
I have a database I want to load tire and brake measurements into. I have created a table which I enter records into, including the date, measurement, the wheel position and the item (tires or brakes) being measured.
On the form I have a picture of a tire and a brake at each wheel position and I would like to be able to display in the control by each item the latest measurement in the main table that matches that wheel position and item.

Is there a way, aside from using auto number, to find a records postion. I am using a list and want to be able to double click an entry and have it open a form and go to that record. However I can't use auto number because I allow for the deleting of records, and once deleted the auto number no longer corrilates to the records position.
If anyone knows of a different sytem that renumbers after deleting a record that would be great if you could share it with me. Or if there is a way to open a form and use goto record but instead of using record postion use where statement.
If anyone has any other ideas on this please share. Thanks.

Hi, I have a cross-ref table (called MFC_CIBC_XREF) which links a bank account to a fund number and a general ledger number. It should be a unique relationship, wherein (the "=" means corresponds/links to)
Bank Account # "=" Fund #
For each bank account, there are sometimes multiple currencies being used, so each currency then links to a general ledger account, such that
Bank Account #.Currency = Fund #.General Ledger #
Sorry, if that's kinda cryptic, but here's an example:
Bank Account - ABCD123
Currencies operated in - CAD, USD
Fund # - F30
Based on the above, ABCD123 "=" F30, and including the general ledger numbers, ABCD123.CAD "=" F30.100, ABCD123.USD "=" F30.8121.
Basically, it's a way to keep track of not just the transactions for a particular bank account, but for the transactions in a particular currency.
Anyway, as I said, it's supposed to be a 1-to-1 relationship: each BankAccount.Currency should correspond to 1 and only 1 Fund.GeneralLedger. However, there are some entries in the table which have each BankAccount.Currency corresponding to multiple General Ledger numbers. Using my example above, ABCD123.CAD has two records in the table, one corresponding to F30.100, and another corresponding to F30.8101. This was probably because F30.8101 used to be linked to a different bank account, that got merged (ie, it might have been linked to ABCD124.CAD that then got merged into ABCD123.CAD).
Now I want to run a query on MFC_CIBC_XREF and find all the records where for each BankAccount.Currency, there is more than one Fund.GeneralLedger. I don't really know that much SQL, and even in Design View, I'm not sure of the statements to use. Any help is much appreciated.

I'm fairly new to SQL and have a problem finding the latest record.
Lets say I have a development project that has many disbursal payments to be sent. I want to find the latest disbursal record created for that one project instead of having all of the disbursal records show on the query.
I'm trying to work out how to do this in a query but haven't got a clue where to start.
Please, if anyone can help I'd be very grateful!:D

I am working on a jobs database where employees enter information where the job is being handed off to. I want to create a table showing the latest job entry by date. The jobs are listed by "Job Number" and when I try to create a table and remove the duplicate "Job Number" it does not always remove the oldest entries.
Any help would be appreciated.

Two of the fields in my query are for Progress Note and Progress Note Date. Each client has several progress notes. How can I have the query show only the Progress Note with the latest date?

I am trying to customize one of my query table, so that it shows the latest review date of an employee (with multiple entries). I have gotten the SQL statement to work so that it shows the latest employee review date which is greater than the current date. But if the employee has 2 records after the current date and I want it to show the latest entry of the 2. I don't know to put add a sub-Select statement or whether to add another criteria in the Where criteria.
e.g. Current Date = May 25, 2005If Employee A's next review date is set for June 1, 2005 but has already been reviewed (the next review date is May 31, 2006). The query will show the June 1, 2005 and not the latest entry of May 31, 2006.
Because there are 2 review dates that are after the current date. What should I do to make only the latest entry appear?
Below is the my VBA code so far, which produces the above result.
SELECT tblEmp.fname, tblEmp.lname, tblEmpWorkHistory.[current store], tblEmp.position, tblEmpSalaryHistory.salary, tblEmpSalaryHistory.next_review_date
FROM (tblEmp INNER JOIN tblEmpSalaryHistory ON tblEmp.ssn=tblEmpSalaryHistory.ssn) LEFT JOIN tblEmpWorkHistory ON tblEmp.ssn=tblEmpWorkHistory.ssn
WHERE (((tblEmpSalaryHistory.next_review_date)>Now() And (tblEmpSalaryHistory.next_review_date)<=[Please enter the Next Review Date]))
ORDER BY tblEmpSalaryHistory.next_review_date;
My brain is stuck and can't figure it out. I hope any fresh mind could help me out. Thanks in advance.

If I have four date Fields in a query, Astart, Bstart, Cstart, and Dstart and want to have a calculated field to find the latest date for each record how would I do that? I have tried things like:
LatestDate: MAX(Astart, Bstart, Cstart, Dstart).

I am trying to find the latest date in a table where the dates are in 2 separate columns and multiple rows. (there are business reasons why there are 2 dates per row they represent different but comparable activities)
I have a table "Assessment tracker" with the following structure
Name Type
Candidate short text
Unit short text
EV1 Date Date
EV2 Date Date
My Data:
Candidate Unit EV1Date EV2 Date
TH1 10 07/05/2015 25/05/15
TH1 10 07/05/2015 07/06/15
I have a query "Candidate AC Dates" that compares the 2 dates EV1 and EV2 and outputs a 3rd column with the latest date.
Query:
PARAMETERS [Candidate Name] Value;
SELECT [Assessment Tracker].Candidate, [Assessment Tracker].Unit, [Assessment Tracker].[EV1 Date], [Assessment Tracker].[EV2 Date], Max(MaxDate([Assessment Tracker]![EV1 Date],[Assessment Tracker]![EV2 Date])) AS Achdate
FROM UnitData INNER JOIN [Assessment Tracker] ON UnitData.Unit = [Assessment Tracker].Unit
[Code]....
Output:
CandidateUnitEV1 DateEV2 DateAchdate
TH11007/05/2015 25/05/201525/05/2015
TH11007/05/2015 07/06/201507/06/2015
It does this by using a function shamelessly copied from the web somewhere...
Function Maxdate(ParamArray FieldArray() As Variant)
' Declare the two local variables.
Dim I As Integer
Dim currentVal As Date' Set the variable currentVal equal to the array of values.
currentVal = FieldArray(0)
' Cycle through each value from the row to find the largest.
[Code]....
This is working well (I think)
I then want to find the latest date for the 2 records i.e. the Max value for the Achdate.
Query:
SELECT [Candidate AC Dates].Candidate AS Expr1, [Candidate AC Dates].Unit AS Expr2, Max([Candidate AC Dates].Achdate) AS MaxOfAchdate
FROM [Candidate AC Dates]
GROUP BY [Candidate AC Dates].Candidate, [Candidate AC Dates].Unit
ORDER BY [Candidate AC Dates].Candidate, [Candidate AC Dates].Unit, Max([Candidate AC Dates].Achdate) DESC;
But this is returning
Candidate Unit MaxOfAchdate
TH1 1025/05/2015
I expect it to return
Candidate UnitMaxOfAchdate
TH1 10 07/06/2015
It looks to me like MAX is considering only the day value rather than the whole date. I suspect this is because it is considering the results of the function in the first query as a short text rather than a date field. (I've tried to force this through declaring the variables as dates but don't know where else to force this. (I am UK based hence the DD/MM/YYYY format)

Giving up after a zillion tries. I have a table (tblLOADS) containing: BROKER, PUDATE, MATERIAL & DRIVER. I am able to create this query:
SELECT tblLOADS.L_ID, tblLOADS.BROKER, Max(tblLOADS.Pudate) AS MaxOfPudate, tblLOADS.Material, tblLOADS.Driver
FROM tblLOADS
GROUP BY tblLOADS.L_ID, tblLOADS.BROKER, tblLOADS.Material, tblLOADS.Driver
HAVING (((Max(tblLOADS.Pudate))>0));
Problem: It's datasheet view displays all of the records for BROKERS, PUDATE, MATERIAL & DRIVER, instead of ONLY the records for the last PUDATE of each of the BROKERS, with their corresponding MATERIAL & DRIVER fields.

The main form has a drop down box for the user to find the client record he wishes to add new visit data in the client visit history subfile.
When the client is found, a history subfile is loaded which has all of the prior client visits.
The history in the subfile contains two pieces of data:
date of the visit mm/dd/yyyy
# members in clients' family NNNN
The subfile history is sorted from oldest date to most current date.
For the user to add a new visit for this client, he must scroll down to the last record in the subfile and then add the new visit for this client.
Is it possible to eliminate the need for he user to scroll down to add a new history record.
I tried to sort the history subfile in descending order of date, but that only resulted in having the old history data in the correct order, but the place to add a new visit still remained on the bottom. The user still had to scroll down to add the new visit.

I'm extremely new to access and have been given the task to create and send a report for the number of rejects at the end of the day. I'm trying to set up a query to do this but it isn't working quite as I want it to.
I have Q1-C that is set to count the number of rejects at stations. However when I run this query, it counts total rejects by type (all records) and not by date. For example, on 12/3/12 there are 2 rejects (1 - Epoxy on screen and 1 - electrolyte leaks) but the query counts 17 electrolyte leaks and 1 epoxy on screen for 12/3/12.
Next I would like to build a report that would display the type of rejects of the last day for both 'Rejects at Stations' and 'Screen Rejects'. So the report "Productions Rejects"should show rejects on 12/3/12 for Q1-C and 12/4/12 for Q1-O. However, the report now shows all the dates of rejects.
I have attached the database I'm working on.

I keep getting the above error in access 2010 and cannot see where the error is. I have checked that datatypes are the same. It keeps referring to type conversion failure and didn't add (1) record due to a key violation.
Code:
INSERT INTO Requests ( [Request no], [Date-time received], Customer, Dept, Type, [Service level], [Received by], [Date-time due], Quantity, [Cust requestor], Status )
VALUES (9896, NOW(), 'DEMO', 'Demo Ltd', 'I', 'S', 'LT', NOW(), 1, 'LT', 'O');

Hi,
I am facing an issue as described in the following:
Scenario:
I have an assignment where the client requires to store its customer detail electronically (ie In soft copy). (e.g Last 5 years data are in hard copy/hard Form format).
They require an application that will help them to enter 10,00,000 records (customer details) in a given span of time.
They have suggested that almost 70-80 operators will work simultaneously in respective console to enter customer information.
Now, every active customer has account number. New customers are given account number from inactive ones.
So, there is a high possibility that while operator1 enters new customer detail and at the same time operator2 while attempting to enter the old customer detail of the same account number will not be allowed as the account number is unique.
My concern is:
With such a huge number of records to enter, will the application get slow. I plan to develop it in access_FrontEnd and SQLserver2000_BackEnd.
I wish to validate account number search: ie when operatorX attempts to add customer record to database it will first check if the same account number already exists.
If I am able to make anyone understand my concern.
Any suggestion is highly appreciated.
Any suggestion in the design aspect…
Thanks,
Prodigy.

How would one go about comparing 2 tables and finding those records that are not common to both tables? For instance, I have a table that I suspect some records have been accidently deleted by the user. I would like to compare that table to an older version of the table, and list only those records that exist only in the older version of the table.
Thanks.

Iv'e looked through several date functions but cant figure out which one to use or how. I want to produce all records for a period of 1 year, for 1 year ago. i.e if I run the query during any month of the 'current year' (obvously) if its after August it will show me the previous year of August to following July. My Start date is always August 1st of any year through to the following July 31st. It is relatively straight forward (I think)if it's from January to December because year part is the same but this becomes more complicated when you cover two different Year parts. I dont want to have to use a parameter Query of 'start date' and 'end date' I want to be able to run the query based on the system date now(). Any help would be appreciated thanks.

Hi, I have a table contains 5 fields are shown as below, how I can write a query to find out the duplicate of the records? I have created a couple of queries by using Find Duplicates Query Wizard to do it. But the results are not accurate enough.
Field 1: ID
Field 2: Trading Name
Field 3: Location No
Field 4: Location Street
Field 5: Location Suburb
IDTrading Name Location NoLocation StreetLocation Suburb

41294Arashi Japanese Resturant41Courtenay PL
150Arashi Kushi Yaki Bar41COURTENARY PLACE
From the data sample, I could like to find out the duplicated records. One of the queries is shown as below. But they cannot pick up these records. Any better way to find the duplicated records? Please help.
SELECT DISTINCTROW [C&B-will].[trading name], [C&B-will].[location street], [C&B-will].Field1, [C&B-will].[location no]
FROM [C&B-will]
WHERE ((([C&B-will].[trading name]) In (SELECT [trading name] FROM [C&B-will] As Tmp GROUP BY [trading name],[location street] HAVING Count(*)>1 And [location street] = [C&B-will].[location street])))
ORDER BY [C&B-will].[trading name], [C&B-will].[location street];
