Multiple Effective Dates (latest Date)
Jan 17, 2007
Below is the code I have for a query. This query shows Processes, Operations, etc. Due to multiple Effective_ (Effective_ stands for Date) The Operations show multiple times. What I would like to do is have each Operation show only one time based on the latest Effective_ i.e. If Operation START-UP is listed three times due to three effective dates 2007-01-04, 2007-01-08 & 2007-01-17 I would only like to the the one associated with the 2007-01-17. Is there a way to accomplish this in my query?
SELECT ASSYROP.PROCESS, ASSYROP.OPERATION, ASSYROP.OPERATION_, ASSYWC1.PROCESS_AT, ASSYROP.OPERATIO_1, ASSYROP.EFFECTIVE_
FROM ASSYROP INNER JOIN ASSYWC1 ON ASSYROP.OPERATION = ASSYWC1.OPERATION
GROUP BY ASSYROP.PROCESS, ASSYROP.OPERATION, ASSYROP.OPERATION_, ASSYWC1.PROCESS_AT, ASSYROP.OPERATIO_1, ASSYROP.EFFECTIVE_
ORDER BY ASSYROP.PROCESS, ASSYROP.OPERATION, ASSYROP.EFFECTIVE_;

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)

I'm trying to create a query that has a calculated field that shows a maximum value from multiple fields.
As far as I can find, this is not built into Access, so I've used this code from a Microsoft page:
Code:
Function Maximum(ParamArray FieldArray() As Variant)
' Declare the two local variables.
Dim I As Integer
Dim currentVal As Variant
' Set the variable currentVal equal to the array of values.
[code]....
The problem I'm having is, well this doesn't work for me.I'm a bit of an beginner VBA coder, but I understand this code and don't know why it won't work.It only displays the value from the field within the brackets.The values used are Dates, so I need to display the latest date from multiple fields.

I am trying to create a query in Access 2010. I have 2 tables BU and Color. BU has employee ID, the BU the employee is assigned as of a date. The Color table has the employee ID, a color and a date. Based on the date in the Color table, I want to select the BU from the BU table. The query should bring in the BU that the employee was assigned to as of the date in the Color table.
For example, if emplid 12345 was hired into BU abc as of 12/31/2013. Emplid 12345 was transferred to BU xyz on 1/15/2015. In the Color there are 2 rows for 12345. One with a date of 12/31/2014 and one with a date of 2/15/2015. I want the query to return abc on the row with the 12/31/2014 date and xyz on the row that contains 2/15/2015.
Attached are the two tables. I have highlighted the expected results in yellow on the Color spreadsheet.

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.

On my main form, I have a subform to input multiple dates, using date picker.
I also have a text box on the main form to input single dates, again using Date Picker.
On entering both the single date text box and the subform, I don't want the (default) date to be visible. I only want the date to be visible once I have selected a date from the Date Picker.
I have figured out how to do this with the single date text box. I have simply defaulted the forecolor to be white so that you can't see the font against the white backcolor. Then on the Change Event, I set the forecolor to be black. Works like a charm.
However... This same approach will not work with the subform. I've tried playing around with a bunch of different events, but so far nothing allows me to re-create what I am able to do with the single date text box on the main form.

I created a pop-up that appears when i open my report so that I can automatically sort through the report by date. However, the report will only allow me to choose one date and i need to be able to choose multiple dates. This pop-up is connected to a list box which has the multi select turned on. How can choose multiple dates through my pop-up?

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.

I've run several searches and can't seem to find what I'm looking for, so here goes:
Have a table with several (maybe as many as 30) dates related to each employee, such as:
NAME-------CLASS 1-----CLASS 2----CLASS 3
J.Johnson.....10/16/05 ......12/17/05...12/25/05
S.Smith.........09/05/05......10/15/05
Not all employees will have entries in every class.
Need a query to result in most recent Date for each employee, such as:
--------------
J.Johnson......CLASS 3........12/25/05
S.Smith.........CLASS 2.......10/15/05
Any suggestions?

This is what I need:
PROCESS EFFECTIVE_ OPERATION_
1/010/1-8TCOWLFEEDER 2005-11-09 10
1/010/1-8TCOWLFEEDER 2005-11-09 20
1/010/1-8TCOWLFEEDER 2005-11-09 30
1/010/1-8TCOWLFEEDER 2005-11-09 40
Out of the records above I would only want to see the records with the 2005-11-09 date. The dates can vary based on processes so I really need something that selects the the latest date for each Process and Operation. I would like to do this in a query or multiple queries.
Thanks for any help.

I am trying to create a query or series of queries that will identify the latest record of a field called CheckInDate. The table will have multiple entries. For example.
Book#__________CheckOutDate_____________CheckInDat e
__1_____________01/01/2007_______________03/01/2007
__1_____________04/01/2007_______________05/01/2007
__1_____________01/01/2007_______________
__2_____________01/01/2007_______________02/01/2007
__2_____________02/05/2007_______________04/27/2007
__3_____________01/01/2007_______________03/01/2007
__3_____________05/01/2007_______________07/01/2007
I need the results to be:
#1(ALL) will not be listed, as there is a book still checked out
#2 will show the record with the 04/27/2007(ONLY), as I want the last time the book was checked out.
#3 will show the record with the 07/01/2007(ONLY), as I want the last time the book was checked out.
I currently have a somewhat flat table where this is concerned. Please advise on what I would need to do to create this. Thanks!

I have a table that contains readings from several pieces of equipment as well as the status of each one. Each record has a timestamp, equipment number, status, etc. What I want is to create a query that will return the latest record for each equipment number. Simplified example table:
Timestamp EquipmentNumber Status
Today ------Machine1 ----------Running
Today ------Machine2 ----------Running
Yesterday -Machine1 ----------Down
Yesterday -Machine2 ----------Running
There are more than 20 different Equipment numbers and they are read several times per day and sometimes some of them get missed. What I'm looking for is a way to get a list of all the machines with their latest reading so they can tell which machines are running and which are down based on the last time they were read (instead of specifying a date). I can get this for one machine with no problem. I'm having trouble getting it for more than one machine. I tried a union query (with just 2 of the machines included for testing) but it only returns the results from one machine:
Code:
SELECT TOP 1 TestCompressorRoundQuery.LoggedAt, TestCompressorRoundQuery.AssetNumber,
TestCompressorRoundQuery.CompressorID, TestCompressorRoundQuery.Status, TestCompressorRoundQuery.CompressorIntegrity, TestCompressorRoundQuery.Notes
FROM TestCompressorRoundQuery
WHERE (((TestCompressorRoundQuery.AssetNumber)="104399"))
UNION ALL
[Code] ....
I'd rather not have to create a seperate query for each machine and then join all of those together! I think perhaps a Union query might not be the correct approach. All the data is coming from only one table.

I have a simple table in Access 2003:
Case# (numeric)

Some of the date fields may be null; If null then that date may NOT be selected
I am trying to write a query that returns:
Case#
Item#
Only the most recent date in any of the four date fields
The heading that matches the selected date field
ie:
Case# = 251
Item# = 4756
Most Recent Date = 7/8/2005
Matching Heading = "ItemOpen"
I have been searching and reading for two days-

I'm trying to sort dates by the latest date when the query returns multiple IDs with different results. Ex.
ID1 1/1/2006
1/8/2006
ID2 1/2/2006
1/9/2006
In this example I would want ID1 with the date of 1/8/2006 and ID2 with the date of 1/9/2006 since they are the latest date. I will have many IDs that I need to run a query on that will all return the latest date. TIA

I need to find the LATEST date in field Recdate that is 45 days or older in a query. I have tried <Date()-45, etc. but it returns all dates not just the last one. Does this require a range of dates to do this ? If not, how would I id the last date input ?

I am trying to run a Query that searches for a single Tool ID Number and returns the transaction record that has the latest date. My query currently is this:
SELECT LocationStatus.ToolID, LocationStatus.CurrentLocation, LocationStatus.DateofEvent
FROM LocationStatus
WHERE (((LocationStatus.DateofEvent)=(SELECT MAX(dateofevent) FROM [LocationStatus] AS t2 WHERE t2.[ToolID] = [Tool Number])));
But the problem I am having is that the query is returning MULTIPLE Tool ID numbers with matching dates. Before the query runs a parameter box pops up asking for a Tool ID number but there should only be one record returning. HELP!!!:confused::confused:

Hi guys
I am trying to create a simple database to keep track of computer components that I order for custom PCs. The data is fairly basic Quantity, Description, Stock Code, Delivery Status, Cost, Cost+VAT, Date Delivered. The list is currently 500+ rows of data. I simply cut and paste this info directly from my online invoices.
What I want is to be able find the the last price paid for an item (often the same items have different prices week by week) Eventually I would like to be able to create a rough quote using the latest prices (plus mark up) and also view a price history.
I would also like to include a few pictures as URL links to the suppliers website ????
At present the data is in Excel and linked to a single table in Access (but this can be changed). I realise that I have to group the records somehow but cannot get it to work. At present it lists every record either in date order or product order.
The stock code should not change, but product descriptions do. So any links to pics would be based on stock codes
Someone please tell me how to display the full list of products but only the latest price/date
If you think the current format is rubbish then feel free to suggest an alternative. I much prefer Excel but have never really got to grips with Access (used to be a vba programmer with Excel). To link to pictures and hide data that customers might see Access seems the obvious choice. So I try again!!!!!
Thanks

I have two tables. The first is called Drawing Register and contains the fields Drawing No (primary field) and Drawing Title.The second table is the Drawing Register Details table which contains the fields Drawing No (joined field - Drawing Register table), Revision, Revision Notes, Date Issued.
I have a query and report which will list all the revisions for each drawing. This is very important and useful. However I want a summary report which will only show the last revision for each drawing.
I copied the original query, turned on the Totals option and under the Date Issued field changed Group by to Max. However it is still returning all results for each drawing instead of only the last issue date for each drawing.

Hey Guys & Gals, extreme newb here attempting to display the latest activity date in an SKU activity db in a query that spans 12 months with multiple activity dates on each of the 1,200 SKUS.
I have this so far and of course it only shows the last (DMAX) activity, not SKU related. How can I relate this result to each SKU to diplay the latest activity for each.
SELECT [Usage06-07].workorderDateClosed, [Usage06-07].qty, [Usage06-07].itemNo, [Usage06-07].Item
FROM [Usage06-07]
WHERE ((([Usage06-07].workorderDateClosed)=Dmax("workorderdateclosed","usage06-07","item")))
ORDER BY [Usage06-07].Item;
Thx in advance for your patience :)

Hello All...
I'm very new to Access.. so please forgive my ignorance..
Here is the scenario..
I have a table with two fields named "item" & "description" that contains 10 records total.
I have another table with 100 records with the fields "invoice #","item", "price paid","date paid","time paid".
The item fields are linked between the two, and the 100 records contain different invoices for these ten items.
I want to pull the price paid off of the latest invoice, based on the time and date... What is the easiest way to do this?
Thanks!
