Replacing Most Recent Record
Dec 11, 2007
Hi, Im building a DB that basically tracks the hours people have worked,
its all going fine apart from one major bug which i cant get my head around, I am trying to work out a way so that if someone decides to change the hours they have worked it replaces the existing record and does not create a new record.
Each record has a unique user ID attached and each day is dated, do you think this is a VBA solution or a change in the relationships perhaps?
Sorry fi there is already a similar answer to this question on the forum, but i couldnt find one!:confused:
Thanks in advance,
Paul

Hello all
I'm sure the answer is on here somewhere but trying to find it and then getting it to work is a bit of a problem, so i resorted to posting.
I have 5 tables
Partnership Details, Invoices, Funding, Communication, Communication Types.
the field Partnership Name in the Partnership Details table has a one to many relationship with the partnership name on tables: Invoices, Funding and Comunication.
What I want to do is create a query that will show the most recent invoice (detirmined by date) and the most recent funding (detirmined by date) for each partnership.
I can do this using max if I only want the feilds Partnership name, invoice date and funding date. however I want to create a report that will show several feilds from partnership details and I want to show the invoice no. and amount as well as the date and also the amount and notes field for funding
Is anyone able to help?
Thanks

My form has a button that opens a report. This report is based on a query that sets the report to display ONLY information related to the person in the current query record.
How can I get the report/query to display ONLY the last (most recent) record in the query?

Hi--I have a subform where a contact's contributions are entered. After much wrangling with the subform's properties, I finally got more than one record to display at a time, but is there a way to get the contributions displayed in descending order (i.e. more recent to less recent) without having to totally redo the subform by basing it on a new underlying query? I tried sorting the contribution date of the underlying bound table that way, but it had no effect.
Thanks for any help.

I have a database with many tables, but only two are relevant to my question.
tblPersonnel holds (amongst other fields) UniqueStaffNo (primary key), Name, Dept, FirstAider (Yes/No).
tblCourses holds details of all courses attended by staff and is linked to tblPersonnel by the UniqueStaffNo. Fields in this table include the CourseTitle and CourseDate (short date format).
I can easily identify who is a First Aider by selecting on tblPersonnel.FirstAider and I can identify which of the thousands of course records are First Aid related by looking at tbl.CourseTitle.
My question is - how can I produce a list of all current first aiders showing ONLY their most recent first aid course (latest CourseDate) so that I can calculate when they need to renew their certificate?
Any help more than gratefully received. Thanks.

I have a TRANSACTIONS table that adds a new record each time a customer makes a payment. Fields are: our account number, date of payment and amount of payment. Our account number has a relationship with the main CUSTOMERS table which never changes.
I need to query out the most recent payment record for each customer in order to arrive at the most recent date a payment was made.
I've been looking over my books and having a hard time figuring out how to do this. Any help will be appreciated.
Thanks,
Mark A.

I have a database table comprising inspection records for about 300 process control instruments. A new record is entered for each inspection so that an inspection history builds up for each instrument.
For one report I need to extract all the records with the only the latest inspection date for each instrument.
I attempted to build a query using the design grid screen. Initially I thought I could use the "Max of" approach as I have done with numbers. This did not work so tried without success to convert the dates to serial format thinking I could "Max of".
Have now concluded that a module is needed. However with my Access Basic programming skills this would take me a couple of weeks and still be wrong!
Can anyone point me in the right direction?

My database includes a Project table and a Status table. They are linked by the ProjectID. The status table contains records sorted by date pertaining to work accomplished on each project. I have created a report based upon a query to give me an update of the status of each project. I only want to see the most recent record for each project from the Status table in my report.
How can I accomplish this?

I have a table similar to the following:
PatientID | LabID | LabDate | Result
001 | 55 | 01jan14 | 9.5
001 | 55 | 01feb14 | 10.0
001 | 55 | 01mar14 | 8.7
001 | 66 | 30jan14 | 11.2
001 | 66 | 30feb14 | 15.4
001 | 66 | 30mar14 | 13.0
002 | 55 | 01jan14 | 12.1
002 | 55 | 01feb14 | 9.9
002 | 55 | 01mar14 | 14.5
002 | 66 | 30jan14 | 16.5
002 | 66 | 30feb14 | 13.0
002 | 66 | 30mar14 | 10.0
Using a single-step Access query, I need to retrieve, for each PatientID, the most recent LabDate and Result *of a given LabID*. Thus, from the example dataset above, the desired output for LabID 55 is:
PatientID | LabID | LabDate | Result
001 | 55 | 01mar14 | 8.7
002 | 55 | 01mar14 | 14.5
I have searched this forum and others, but have not found an answer that I can directly tanslate to my situation. I have successfully written queries (with included subqueries) that retrieve the most recent of all the Labs, but have failed at obtaining a result dataset that contains only the records within a specified LabID.
For example, the query below fails because whenever the most recent of *all* the LabDates is not the same as the most recent of *the LabDates with a LabID=55*, the correct record is not included in the results. In the example dataset above, 0 records are returned.
SELECT a.PatientID, a.LabID, a.LabDate, a.Result
FROM Labs AS a
INNER JOIN (SELECT PatientID, MAX(LabDate) AS MaxLabDate FROM Labs GROUP BY PatientID) AS b
ON (a.PatientID = b.PatientID) AND (a.LabDate = b.MaxLabDate)
WHERE (((a.LabID)=55));

I have two tables with a one to many relationship. The tables are linked by the INDEX column.
EXAMPLE:
Code:
TABLE_1
INDEX NAME
1 Name_A
2 Name_B
3 Name_C
TABLE 2
INDEX NUM_INDEX STATUS
1 1 REJECTED
1 2 REJECTED
1 3 OPEN
2 1 CLOSED
3 1 REJECTED
3 2 OPEN
I need the NAME field from TABLE_1 and the Last STATUS field from TABLE_2 (MAX of NUM_INDEX).
Example:
Name_A, OPEN
Name_B, CLOSED
Name_C, OPEN
SQL that I have now.
Code:
SELECT A.FIN_Finding_Number, B.Max_Index
FROM TBL_Findings AS A INNER JOIN (SELECT RES_Finding_Index, Max(RES_Response_Index) As Max_Index
FROM TBL_Response GROUP BY RES_Finding_Index ) AS B ON A.FIN_Finding_Index = B.RES_Finding_Index
WHERE (((A.FIN_Finding_Index)=34));
This SQL statement will return me the Finding_Number and Max_Index. I don't need the Max_Index. I need the Status. If I put the Status in the Sub-Query and GROUP BY it, it will return both REJECTED and OPEN. I just need it to return OPEN.

I have a table of accounts and a table of rates. There is a one-to-many relationship between them (i.e. each account can have multiple rates, each with their own - unique - effective date)
I'm trying to build a query which will show me all of the accounts in the accounts table and the most recent rate (based on the effective date) for each of those accounts.
This is as far as I've gotten with the SQL :
Code:
SELECT [tblAccounts].[AccountID], [tblAccounts].[AccountNumber], [tblAccounts].[AccountName], [LatestRate].[IntRate], [LatestRate].[EffectiveDate]
FROM [tblAccounts]
LEFT JOIN
(SELECT TOP 1 [tblRates].[AccountID], [tblRates].[IntRate], [tblRates].[EffectiveDate]
FROM [tblRates]
ORDER BY [tblRates].[EffectiveDate] DESC) AS LatestRate
ON [tblAccounts].[AccountID] = [LatestRate].[AccountID]
But this can't work because the [LatestRate] subquery can only ever return one record (i.e. the most recent rate across all of the accounts)
I need the most recent rate for each of the accounts in the main query
(FYI - I use an outer join as it is possible for no rate to be available in the rates table for a given account, in which case I want to return the null value rather than omit the account from the resulting dataset...)

I have a database that is used to allocate appointments to our staff. It has 2 tables, one that lists the clients we need to call in that day, and another that stores details of each contact attempt. I'd like to design a query that find all clients who we have not dealt with so we can easily get their details in a list. I know what the criteria for the query would be, but I'm stuck for how to actually execute it. Here are the details.
Table tClients stores the current clients - primary key is named "clientRef"
Table tContactEvents stores each contact attempt and the date/time is stored in a field named "dateTime".
When an entry has been dealt with successfully a yes/no field named "completed" will be set to "Yes".
There may be many attempts to contact a specific client on a given day, unsuccessful attempts will not have the completed flag set.
Once the completed flag is set that client will be ignored so no further entries will appear.
So I need a query that searches tContactEvents for the most recent match to each number in tClients.clientRef and checks if the completed flag is set. If the completed flag is false, or if the number has no match (i.e. no contact attempts made yet) then the clientRef should be displayed. I also need this to be restricted to the current date, as the same client could have rebooked their appointment to a different day.

I have a basic database design, well I think so anyway. It only has two tables:
1. tblClientInfo
2. tblNotes
Basically each client has multiple notes/comments that can be linked to its record, hence the tblNotes table. The two tables have a one-to-many relationship, being that each customer can have many notes.
I then have two forms:
1. Claims Loss Form
2. tblNotes_DatasheetSub1
So I can enter multiple notes for each customer. The problem I am having is with the report output. It wants to print every note (record) that is linked to the customer. I just need it to print the most recent note for each customer (It would save a lot of wasted paper).
Example of a print out of what it is doing:
John Doe - 123 Easy St - Notes 1 (Most Recent Note)
John Doe - 123 Easy St - Notes 2 (Previous Note)
John Doe - 123 Easy St - Notes 3 (and so on...)
It is printing duplicates of the same customer by adding the additional notes for that same customer on a new line.
How can I tell it to only print the customer one time in the report, and most importantly, to only use the most recent note that is linked to the customer?
I tried using DMax("NoteDate","tblNotes"), but this only returns one customer with one note. I need it to do that for each and all customers.
I have successfully ran a subquery (two queries with one linked to another) by following detailed instructions from this page I found: [URL] .... It works, but the problem is it only shows the latest date for each note, not the actual contents of the note. I feel so close with this option, but so far at the same time.
The TOP n records per group looks promising that I found here: [URL] ...., but I honestly don't know how to implement it correctly in my SQL. I am very much still learning Access and apparently have stumbled into something that is much more complicated than I had originally imagined. I just assumed I could filter the duplicates out, or tell access to print the last or most recent note record for each customer.

I have a customer who made a query with a field that looks like that:
NewField: iif(Field1=True and Field2>100 and isnull(Field3);"Blue";iif(Field1=True and Field2>100 and not isnull(Field3);"Black";iif(Field1=True and Field2=100 and isnull(Field3);"White";... And so on, for miles and miles.
Although it works, and fast enough, I don't like the way it is displayed and I am sure that it could be even faster without all these iif.
Any idea about the best way for me to handle this kind of query?
Thanks!

I have a main table which contains data on Oilfields. This is set up with an auto number for ID and a name of each oil field. I have other tables which contain things such as Pipelines, Wells and Platforms, which are linked back the the main table.
The problem is that the database was given to me with the links being between the Oilfield_Name, and not using the Oilfield_ID (which is not present in the 'satellite' tables). How can i add the oilfield_ID column to the 'satellite' tables so i can link them properly?! (i can obvioulsy physically add an 'Oilfield_ID' column to the 'satellite field', but how do i populate it with all the correct IDs from the main table, to suit what is in the 'Name' column of the 'satellite' field- does that make sense?). I suppose I need to replace all of the Names with the IDs?
This has been giving me such a headache. The Oilfields table has 2500ish records, with as many as 1200 in the other tables linked to it.

hi. i are replacing queries in my tables to get the database ready to convert to SQLServer.
Am having a problem replacing a query that is brings in a table for a drop down and inserting the selection in the record.
during creation, the record shows a date, id, task, hours.
the datatable needs date, id, task_code, task_name, task_job, hours.
On "task" the drop-down allows for selection of several choices that are 3 columns wide. i can get the columns to show but only the first column currently goes in my new table. the table's columns that the selection comes from is "task_code,task_name, task_job". All columns are needed as different areas use the same task code but use different jobs or names.
I was told to use a insert into statement, however am having problems with it.
have as follows:
SQLStatement = "SELECT [Task_code], [Job_name], [Task_name] FROM tablea; "
rec.Open SQLStatement, , adOpenDynamic
job = rec(1)
task = rec(2)
rec.Close
SQLStatement = " Insert into [tableb]([Job_name],[Task_name]) " & _
" values (" & job & ", " & task & " ) "
rec2.Open SQLStatement, , adOpenDynamic
db.Execute (SQLStatement)
any point in the right direction would be greatly appreciated.
thanks,
slh

Hi, I have 2 tables with similar data. However I need to compare this particular field called CompanyName in both tables. Reason being human error/exposition data errors. For example, Chef Kitchen Holdings Limited, in one table it is Chef Kitchen Holdings Ltd while the other table is Chef Kitchen Holdings Pte Limited, they both are the same but Access recognise them as 2 distinct datas.
Ｔｈｅｒｅｆｏｒｅ Ｉ need help in comparing datas between these 2 tables for this particular field. So long as there is 75% similarities, one of the 2 tables will have the data replaced.
Is that possible using Access? if not, how about excel? please suggest.
thanks.

OK, here is my situation. I have an access database which is updated automatically every night with new data. My companies solution to this is each morning, the entire database is downloaded to my computer to be used by another application.
In one of the tables, there is a field that doesn't work for my purposes, so each day I have to manually open the table, and change the contents of that field for every record. For example, lets say I have the following table:
Field1 Field2 Field3 Field4
Rec1 Wigets Faucet Model1A
Rec2 Wigets Faucet Model1B
Rec3 Wigets Sink Model1A
Rec4 Wigets Sink Model1B
Rec5 Wigets Toilet Model1A
Each day I manually change Field2 so it reads "Total" and whatever is in Field2:
Field1 Field2 Field3 Field4
Rec1 Total Faucets Faucet Model1A
Rec2 Total Faucets Faucet Model1B
Rec3 Total Sinks Sink Model1A
Rec4 Total Sinks Sink Model1B
Rec5 Total Toilets Toilet Model1A
Each morning when I receive the new database download, they all go back to widgets.
Is there a macro or module I can create to automatically look at Field3, and then assign a new value to Field2 based on Field3's value?
Any help would be appreciated!!!!

I am exporting an Access table as an xml file and need to be able to identify and replace '&', '(' and ')' as they are not accepted in xml.
Does anyone know how a query can be built which will find these characters in fields and update to ' and' or just remove?

I created a database that has a field called "Corrective Actions." I want the user to be able to type in a series of numbers, in the following format: 001, 002, 051, 123. Each number has a certain meaning. For example, 001 means "Upgrade to current revision," 002 means "Replace Unit," and so on. Here is what I would like to happen: The user will type in the numbers in the appropriate format. When the user presses the tab key to go to the next field, I want the numbers to be replaced with the actual meaning. My problem is that I can not figure out how to accomplish this. Can anyone help me?

Hi. I have a database which store the subject title of the mailto link using the upload form. I would like to construct a mailto link that picks up the suject title from my database.

I have a table (which has a few relationships) that contains 10.000 records up-to-date, but I've been making major changes to my database working on an old version from early June, when it had +9000 records.
What I'm planning to do to update the table:
export those 10.000 (up to date) records to a Excel file
delete those outdated +9000 records manually (select all + supr)
import the data from the Excel file so my new database is up-to-date again .
Is this acceptable or could lead to weird errors in the future?
