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 have a list of project, each of which have dates which work were carried out on them. Each project can have more than one date. I want to be able to find the last date that any work was carried out, and then calculate how many days have passed since that happened.
View 6 Replies View RelatedI 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 am trying to make an on-click event that would open a form showing the last inspection done on a site.
Unfortunately, I cannot even first create a dlookup function to use, so I haven't even attempted the rest!
The data needed to reference is in one table, and I just...can't... quite get it.
Here is my last attempt (which at this point probably isn't my best )
Code:
=DLookUp("InspectionID","tblInspections","SITEID = '" & [Forms]![frmFMHome]![txtSITEID] & "' AND InspectionDate = #" & DMax("InspectionDate","tblInspections","SITEID = '" & [Forms]![frmFMHome]![txtSITEID] & "'") & "#")
After breaking it apart I'm pretty sure the DMax function (and using date?) is the culprit, but I can't figure out why.
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 have a query to bring in values, I need to select 2 rows of data but the criteria is as such:
x= starting value on form
now the row of data must match the following criteria previous row to current row(ref temp)<=x And Current row(ref temp)>xnext row to current row(ref temp)>=x And Current row(ref temp)<x
I have dealt with SQL before but how to do the above.The isolated 2 rows of data will then go into unbound boxes on a form from which I will do intercept and gradient calculations.
I am having a problem with calculating a date field in a query. Prior to this posting I've done some research and made several changes to my query. This only resulted in fixing one problem but then creating another problem. Original problem was I had 2 fields, arrived (23:36) and stemi (0:07). I use the following calculation AT_ST: DateDiff("n",[arrived],[stemi]) which resulted in -1409. So my research showed me I had a problem with the date whenever the time went past midnight and trying to calculate a zero hour number. I changed my calculation to
AT_ST: IIf([stemi]>=#11:59:00 PM#,(DateDiff("n",[arrived],[stemi])),(DateDiff("n",[arrived],[stemi]+1440) Mod 1440))
This works fine and gives me the result of 31 minutes which is what I want, however the problems comes in when I change to this calculation any where there was a negative time now has a 1400+ plus value. Such as arrived (7:37) and 1st_eck (7:18) = 1426 where as before it would report -14 (yes, negatives are acceptable for my reporting because sometimes a call to the hospital is placed before the patient arrives so we want to report on the negative splits). I've tried using a nested IIF to calculate for stemi time being less than arrived time, this didn't work when I tried to use it on the calculated query field. I was wondering if I could write something to check the value of the calculated field if it is greater than 1440 and if yes - subtract 1440 from it. So in the example above 1426-1440 = -14. Is it possible to do this within the query or do I need to do it using VBA
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 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:
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!
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.
I have a query with a record id, report date and status.
How do I pull the latest record if the status is AA?
For latest record in report date I used Max in Totals. With just this max it is pulling the latest date for each set of records with the same record id.
This is a start now how do i pull the latest record that has a AA status?
How do I query from this table:

I'm trying to create in access2010
(1) a query that returns the latest record (newest) in a table called 'Invoices' and then
(2) places this value in a form called 'FrmInputInvoices' as the default value when the form opens. Newest record is by Autonumber and the table defaults this to top of table as views newest down to oldest.
Re (1) Query is called 'QInvoices'; the values I want to return in my query is ID (my autonumber) and Invoice_No . Must be a simple answer to put in the criteria, but I can't find this.
Re(2) What code do I use in my Form field named 'Invoice_No when the curser defaults there on opening?
In my Access app I need to get the latest record added of an item from a MS Sql table and check the period between now and the date saved in the record.
So my guess is:
Select TOP 1 * from tbl_StockItems
Where StockId = Loc_StockId
I then need to check the days between tbl_StockItems.LastStockDate and Today.
How would I write an Access VBA query to give me the amount of days and put that number into a variable.
My table appears like this with the following columns:
Name| CUSTNo| ORderNo.| AcctDate| OrderDate| OrderDescription
I would like to write a ms-sql query to return the records of each customer number with the latest OrderDate. One more thing, if the customer has two separate order numbers on the same date(should be the latest date), the query should be able to pull up both the records.
I tried with the code below but its taking a long time to execute and finally hanging up MS ACCESS.
SELECT * FROM TableName AS a WHERE Not Exists (SELECT *
FROM TableName b WHERE b.CUSTNo = a.CUSTNo AND b.OrderDate >= a.OrderDate);
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 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 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.
I'm reworking a db to make it web compatible. Right now I'm working on my Price and Sales tables.There are about 900 Sales records, 450 Price records (for about 45 Items).
I have re-done my Price table with an Autonumber Key field. (It had a multi-key which I understand web db does not support.) Each autonumber key represents a Date with new Price for a Company/Item. The Price change Dates are random.
I have put a Foreign Field in my Sales table for the Price key field.
My dilemma is matching the Sales with the Prices.
When the Price Date and Sales Date do not match (at least half of them don't match), I need to look back in the Price table to the max Date BEFORE the Sales Date in the Sales table for that Company/Item in order to select the correct Price key.
I am trying to retrieve data for a particular record.
When Project field matches a certain project number I want it to pick the record with the latest date in the date field field to select certain data fields(Owner & Rating) from that record.
Below is my attempt. However the problem is that displays all records with that project number and not just the record with the latest date.
Code:
SELECT [Combined PRB Roadmap].ProjectNumber, Max([Combined PRB Roadmap].DateField) AS MaxOfFDateField, [Combined PRB Roadmap].Owner, [Combined PRB Roadmap].Rating
FROM [Combined PRB Roadmap]
GROUP BY [Combined PRB Roadmap].ProjectNumber, [Combined PRB Roadmap].Owner, [Combined PRB Roadmap].Rating
HAVING ((([Combined PRB Roadmap].ProjectNumber)="NR-4237"));
I have a database which has a main form and subform built in linked by parent/child customerid, what i would like to do is search all the subform records from the whole DB and return its parent record on the main form?
Can this be done? because if i use find it will only search the filtered form i have onload of the form?
My onload event is based on fosusername()
I am trying to add a calculated date field in a query, I have 2 fields and 1 of them has a date and the other one i would like to to be 3 years from the date of the first field.
View 3 Replies View RelatedI've been struggling with this for a while, and even though I understand the theory, I can't get my code to work correctly.
I have 2 fields:
CallbackFrequency & Last Contacted.
I want to use these fields to populate a third field (callBackOn) so that we can have a list of candidates that need to be called from a certain date.
CallbackFrequency is added from a combobox, so all values are either 1 Month, 3 Months, 6 Months, or 12 Months.
I have tried creating a calculated field directly in the candidates table, but apparently this is not possible.I've therefore tried to create a query using IIF statement that will calculate this value.To get to grips with the code, I'm only dealing with 1 callbackFrequency at the moment. So far I have:
CallbackOn: IIf([Candidates].[CallbackFrequency]="1 Month", [LastContacted],)
I have not factored in the date manipulation yet, as the query does not display the LastContacted date of the record it finds, it only shows a blank cell,
In a query i have setup, i work out when a tenant is next due to pay their rent.
Looks like this
Tenant Last Payment Date Payment Terms Next Payment Date
User1 01/07/13 Monthly 01/08/13
User2 01/07/13 Weekly 07/07/13
The next payment date is calculated using an IF statement and DateAdd in the query, so if it is weekly it adds 7 days, if it is monthly it adds 1 month.
What i am trying to do is write sub query of this one which shows which tenants are due to pay within the next 7 days.
But the access query seems to ignore the criteria I'm putting in....in the next payment date criteria i have tried specifying >Now() + 7 or >Date() +7 but neither seem to work, it just shows up every record...
