Queries :: How To Get Latest Dates And 3 Other Data For Records From A Table
May 29, 2015
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.

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 have a survey database that I've been using for the last year for monthly auditing of employees files. I need to be able to get monthly audit scores for each employee but grouped by their manager. The problem I'm having is employees have moved between managers throughout the year, so employees that are listed under Manager 2 now were actually working for Manager 1 when the audits occurred.
ie. Audits occurred Jan - April for Employee 1 while they were assigned to Manager 1. Employee 1 moved to Manager 2s team in May. So when running monthly reports for the year Employee 1 audits should fall under Manager 1 for Jan-April and Manager 2 for May-Dec.
I do have a history table set up like:
tblEmployeeHistory
ID (PK)
EmployeeID (FK to Employee table)
ManagerID (FK to Manager table)
MoveDate (date employee assigned to manager)
The Employee table is set up like:
Employee ID (PK)
EmployeeName
ManagerID (FK to Manager table)
The Manager table has the ManagerID and ManagerName.
That's the employee side of things; then I have the tables that store the audit results:
tblAudit
AuditID
FileNumber
AuditDate
EmployeeID (FK to employee table)
tblAuditResults
AuditID; QstnID (Composite PK, QstnID is FK to tblQuestions)
Answer
How can I use AuditDate and MoveDate to relate audits to the managers the employees were under when the audits occurred?

I have a complex database app that has a form called from the main form. It requires two inputs: BeginningDate and EndingDate and I use a calendar picker for date selection. Using data assigned to a variable, I build the SQL query in VBA. The result is:
Code:
SELECT [1733_All Print Orders].[Application], Sum([1733_All Print Orders].[TotalImages]) AS SumOfCCPC
FROM [1733_All Print Orders]
WHERE [Application] = 'CCPC' AND [StatementDate] >= #9/3/2013# AND [StatementDate] <= #9/30/2013#
GROUP BY [1733_All Print Orders];[Application]
[1733_All Print Orders] is a defined query that combines 4 tables together and there are data that falls within the dates for CCPC. But the query returns no records.
I pasted the query to the query builder and using different combinations, I isolated that the [StatementDate] >= #9/3/2013# portion is what returns no records
To complicate matters even worse, prior to today, it worked. I made some adds and changes to another area of the application, but did not touch this code.

I have a table which includes a start date field and completion date field for housebuilding.
I am trying to extract all records that have either a started date or a completed date between 2 dates supplied by the user. I have tried to use Between on both fields but that doesn't return results between the fields.
It workd if I just do it on EITHER the start date field OR the completion date field so that implies to me that I need to break it into 2 queries, one returning start date recrods and the other returning completion date records but then I would need to have somthing that removes records that appear in both the start date and the completion date results.

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?

Running Access 2010 and developed this query to filter out data from a table between times on 2 dates (day before report run and day of report). Covers data from a shift that carries over to the next day.Trouble is, the PC i developed on still operates the query as expected. However, on the PC the database resides (not networked just stored) and operates, the query brings up no data at all unless I remove the Time filtering.
This PC used to operate correctly up until early this year (about 18 months operated correctly) when the PC was replaced due to failure. Access version is the same and I am at wits end to what the cause is. Here is what my query looks like:
Quote:
SELECT Breakdowns.BreakdownDate, Breakdowns.Time, Breakdowns.Shift, Breakdowns.Downtime, Breakdowns.Equipment, Breakdowns.Conveyor, Breakdowns.Fault, Breakdowns.Stopper, Breakdowns.Gate, Breakdowns.Dolly, Breakdowns.Carrier, Breakdowns.FaultType, Breakdowns.Comments, Breakdowns.Tradesman
FROM Breakdowns
WHERE (((Breakdowns.BreakdownDate)=Date()) AND ((Breakdowns.Time) Between #00:00:00# And #6:29:00#) AND ((Breakdowns.Shift)="Night")) OR (((Breakdowns.BreakdownDate)=Date()-1) AND ((Breakdowns.Time) Between #22:30:00# And #23:59:00#) AND ((Breakdowns.Shift)="Night"));

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 have a table where csv files get imported to on a daily basis. The key fields I am working with are a supply number and date. The problem I have is that sometimes the csv file will contain information that is correcting/updating information held in the table. This is creating duplicated records.I need to either create a query to find records that have the same supply number and date or find a way of overwriting the records in the table with the new data.

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 have a table tbl_PolicyDetails with details of the policy the customers have with us.. In the tbl_PolicyDetails, I have two fields (these are the ones in question) called
"policyStarted" - Start Date of a Policy and
"policyPeriod" - Term of Policy Monthly/Annually/Quarterly
So in a Form view I just get the Next installment for the customer based on this information for display.. For example..
Mr Butters Stotch's policy started on 26/04/2013 and is paying Quarterly; the next (i.e. 2nd) installment would be on 26/07/2013..
Ms Wendy Testaburger's policy started on 07/04/2013 and is paying Monthly; the next (i,e. 3rd) installment would be on 07/06/2013..
This is not hard to get.. I have that sorted.. But the problem is, my manager wants to be able to specify two dates and search all policies that will be 'paying in' that Date range should be picked up..
So if the search range happens to be.. 01/07/2013 and 31/07/2013 Then Mr Butters Stotch's policy should be picked up, as his next installment falls on 26/07/2013.. Since this information is not stored, I cannot run a direct Query on this.. Also as the Installment number varies for each customer, I would not be able to just add 1 - Month or Quarter or Annum, and see if the date falls in that range..

I have a table that contains the following fields: ID (autonumber), Item, billing date(mmm/yyyy), count, and approved.
My first query returns records where the approved field is null. My second query returns returns all records for 2 months ago where the approved field is not null.
This is my problem, I need to pull records that have NOT been approved for the prior month BUT if they were approved 2 months ago AND the count is the same, it does not need to be returned in the query. Also, if it was approved 2 months ago but the count is different than what it is for 1 month ago, it needs to show in the query.

Only one table : Customer ID,Customer name , subscription period, subscription start date and subscription end date.
I need values where subscription start date is between date1 and date2 and subscription end date is between date 1 and date2.
Detail explanation:
customer1 subscribed from 2-feb 2012 to 2-feb 2013
customer2 subscribed from 5-aug-2012 to 5-aug-2013
customer3 subscribed from 1-Jan-2013 to 31-Dec-2013
when the user enters date 1 as 1-jan-2013 and date 2 as 30-Jun-2013
Even though the subscription start date is not within the range entered by the user.I need to get all three customers because the subscription enddate falls within the range.And customer 3 is also required as subscription start date is within the range.

I have created a booking system for a set of resources for schools. Most schools have a membership which entitles them to 2 free sets. I have a booking form with a membership subform (membership table), and a booking details subform (kitloan table).
Once a school is selected on the main form, the membership subform shows the most recent record for that school based on schoolID.I want to display the number of sets they have already had within their membership period (can start at any time of the year, and lasts for 1 year) on the membership subform, so we know how many free ones they have left.
I therefore need to count the number of KitBkID (ID of the booking) in the Kitloan table where SchoolID = the SchoolID displayed on the membership subform, and the DateOut (booking date on kitloan table) is between the DateJoined and DateRenewal displayed on the membership subform (from membership table).
I can do this with a query which works when run and provided with the parameters SchoolID, DateJoined, and DateRenewal.
SELECT Count(Kitloan.KitBkID) AS CountOfKitBkID, Kitloan.SchoolID, Kitloan.DateOut
FROM Kitloan INNER JOIN Membership ON Kitloan.SchoolID = Membership.SCHOOLID
GROUP BY Kitloan.SchoolID, Kitloan.DateOut
HAVING (((Kitloan.SchoolID)=[Me].[SCHOOLID]) AND ((Kitloan.DateOut) Between [Me].[DateJoined] And [Me].[DateRenewal]));
What I can't do is get it to run on the form and take those values from the form.From the searching I've done, I'm thinking a DCount should be the way to go, but I cannot get the criteria right. I created a query (KitloanCountQry) so that criteria could come from both the kitloan and membership tables.
SELECT Kitloan.KitBkID, Kitloan.SchoolID, Membership.DateJoined, Membership.SCHOOLID, Kitloan.DateOut
FROM Kitloan INNER JOIN Membership ON Kitloan.SchoolID = Membership.SCHOOLID;
I have put the DCount as the control source for a textbox on the Membership subform (but have tried it in VBA too):
=DCount("KitBkID","KitloanCountQry")
This works but obviously gives me the total for all bookings.
[code]....
Although I have to admit to getting lost in the syntax. This produces #Error.

I have a few queries which are used to create reminder email on training which is due for renewal.Some training required reminder 6 months before 2 year expiry. I use this in the criteria for the training date within query:
Between DateSerial(Year(Date()),Month(Date())-18,1) And DateSerial(Year(Date()),Month(Date())-17,0)
Some training required reminder 3 months before 1 year expiry. I use this in the criteria for the training date within query:
Between DateSerial(Year(Date()),Month(Date())-9,1) And DateSerial(Year(Date()),Month(Date())-8,0)
My problem is with training requiring reminder 6 months before 3 year expiry. Using this criteria:
Between DateSerial(Year(Date()),Month(Date())-30,1) And DateSerial(Year(Date()),Month(Date())-29,0)
Doesn't show any results (although there is training which was done 30months ago, expiring in 6 months time).
Changing the -30 (months) and -29 (months) in above down to -22 & -21 shows records as expected, but anything below -22/-21 doesn't show any records.

I am trying to figure out a logical WHERE condition. I have a Query that gives me data,
Code:
Name | Start | End
--------+-----------------+-------------
Paul | 30-May-15 |
Eugin | 21-May-15 | 28-May-15
Francis | 04-Mar-15 | 08-May-15
Samuel | 10-May-15 | 13-May-15
I want to have only Paul and Francis. As Eugin start is 21-05-2015 and End is the same month, so is Samuel's. So I want to eliminate those two records.I have checked pbaldy's web of overlapping records. But unlike that, I need something customised.
Begins and ends before range - we don't want - Yes
Begins before, ends during - we want this one - Yes
Begins and ends during - we want this one too - NO
Begins during and ends after - we also want this one - Yes
Begins and ends after - we don't want this one - Yes
Begins before and ends after - we want this one -NO

Anyway, I would call myself intermediate level at best with Access. I never expected to have to do so much with it, but when my bosses found out I could do Access basics, they began demanding more and more.
I manage an EMR from which a datapull occurs on discharge to various access databases.
They wanted me to add a triage patient data pull to track what procedures are being done to triage patients. So I built a database with the following 2 tables.
tblTriageVisits and tblTriageProcedures
tblTriageVisits has the following fields
-Patient ID
-Export Time
[Code].....
The tblTriageVisits stores all the patients triage visits. The other table stores what was done to each patient on those visits
It should also be noted that this EMR exports times in number of seconds since 12/31/1975, so TimeProcFMS is the number of seconds since that date for example.
The pulls work great and the duplicate record elimination method works great.
I have to design a couple of different reports based on this data and one in particular has pretty much flumoxxed me.
I need to make a report that lists each patient by date they were there and then shows what was done to them. I have tried several different variations of this as both queries and reports. The report breaks down when I try to get it to show just those procedures that would be for that triage visit. I got to the point where it would group by day and then sort the patients alphabetically. Then I added in the visit fields. And it would put all triage procedures for that patient from all their visits in each visit.
So, I was like great, let me filter out those that don't occur between the two dates, admission and discharge
I used the following two formulas (the first one on the procedure name field the second on the procedure date field)
=Switch(DateAdd("s",[TimeProcFMS],#12/31/1975#)>=[Admission DateTime OB DateTime] And DateAdd("s",[TimeProcFMS],#12/31/1975#)<=[LD Discharge Date/Time DateTime],[Procedures FMS])
=Switch(DateAdd("s",[TimeProcFMS],#12/31/1975#)>=[Admission DateTime OB DateTime] And DateAdd("s",[TimeProcFMS],#12/31/1975#)<=[LD Discharge Date/Time DateTime],DateAdd("s",[TimeProcFMS],#12/31/1975#))
And they work, sort of. They do eliminate those procedures that occur outside of the date range I am looking for. However, the access report still leave spaces in the report where the filtered out items would be.
Did I approach this problem correctly? And if so, how do I get rid of those spaces?
Note, I can read and mostly understand SQL, but am not comfortable working in it yet. And the Access SQL box gives me a headache, it is so jumbled up.

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.

However, I only want to select records between a date range working on my field [DueDate]. If I add the due date field to the current query then it removes the grouping and all records are displayed.

6 06.01.2014 Firma A 6
7 02.01.2014 Firma XY 11
8 03.01.2014 Firma XY 9
9 04.01.2014 Firma XY 7
10 05.01.2014 Firma XY 8
11 06.01.2014 Firma XY 10
how I can get this?
I have this code, but it need hours.
Code:
SELECT tblDates.PosNr, tblDates.Company, tblDates.PriceDate, (SELECT TOP 1
B.Price
FROM
tblPrices As B
WHERE
B.Company = tblDates.Company
AND
B.PriceDate <= tblDates.PriceDate

B.PriceDates DESC ) AS Price

I have a table of SOPs/WIs. Each, with time, gets a new version - this I keep in the child table.
tblVersions
------------
VersionID (PK)
SOPID(FK)
Version (integer)
IssueDate (date)
I want to make a list of the currently valid versions, i.e. for each SOPID pick the VersionID with the latest date.
One can do many things with subqueries and Max - functions, but after some experimentation I have stumbled upon this:
Code:
SELECT Last(tblTest.VersionID) AS LastOfVersionID
FROM tblTest
WHERE (((tblTest.IssueDate)<Date()-10))
GROUP BY tblTest.SOPID;
The function Last has a bit tricky reputation and description on the web. It does yields the right result in my testcase though , see the attached db - run query3.
Query3
Code:
LastOfVersionID
100
90
20
40
666
888
55
8
Update:
Well, it isn't. Just changing the VersionID numbers to something other than an ascending sequence renders an incorrect result with the above query. So what is the best way to get the desired result? (Access 2007)

I'm having trouble with a simple query. They have an access database with a table like this (simplified for this example):

Bob 7 3/3/2015
Bob 8 5/4/2015*
Len 5 1/1/2014
Len 6 2/2/2014*
Len 7 3/3/2015
Len 5 7/4/2015*
---------------------------------
how I would write a query that gives me the latest result that each person earned in each year (I put a * symbol against the rows above that I am talking about)?
Bob 6 2/2/2014
Bob 8 5/4/2015
Len 6 2/2/2014
Len 5 7/4/2015
(The database is normalised and this table has an ID field).
