Queries :: Can A Calculated Field Look At Record Before Current Record
May 1, 2013
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.

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'm struggling with a query to evaluate current and prior record data. I have a query producing 5000 records. I need to group records by Case ID and compare current date record to previous date record to determine if a team and worker name has changed during the year. I need to count how many times a cases is transferred to and out of a particular team from the beggining of the year. i.e., On 1/1/2014-Team1 has an inventory of 500 cases.
During the month 25 cases are transferred into Team1 and 15 cases are transferred out of Team1. So on 2/1/2014 Team1 begins with an inventory of 510 cases. Throughout the year cases come and go from and to Team1 each month so need to figure out how to create a query to count each change. See attachment displaying how the data is listed and how I invision it to work with the In/out column counts.
Specifically, at the begginig of the year (1/1/14) for case ID 1003 you can see it belongs to Mary in Team1 for January and February. Then in March the case is transferred out and went to Joe in Team 3. So for Mary a "-1" is recorded as a negative count for that Case ID. If later in the year the case is transferred back to Mary a "+1" would be recorded. Respectively evaluated for each of the 5000 records to get a total count for each of the teams by Case ID throughout the year.
I've started with DLookup, tried comparing current month to previous month using DMax. It works as long as I only select one case ID used in a separate query but if I use the whole subset (5000 records) it fails. I can't figure out how to group each set of case IDs and then apply the query.
My attempted query: DLookUp("[Team]","[Team_qry]","[Team_qry]![Date]=#" & CStr(DMax("[Date]","[Team_qry]","[Team_qry]![Date] <#" & CStr([Date]) & "#")) & "#")

I need a way to dynamically store a particular value in "field_2" of the CURRENT record depending on whether or not the value of "field_1" of the CURRENT record is identical to the value of "field_1" of the PREVIOUS record within the same table. The table is sorted on "field_1".
So, if the value of "field_1" in the CURRENT record is "ABC" and the value of "field_1" in the PREVIOUS record is also "ABC", then store a value of "PPP" in "field_2" of the current record. IF on the other hand, the value of "field_1" in the CURRENT record is "ABC" and the value of "field_1" in the PREVIOUS record is "XYZ", then store a value of "WWW" in "field_2" of the current record.
I have a report that will use these results to count only the number of records that have a "WWW" in "field_2".
Is this doable, maybe in a query somehow?
I should add that whatever the solution, it needs to be compatible with Access 2000.

Hi,
I have a query that contains the results of repeated tests on a number of persons. The goal of treatment is to get those test results below 50. I need to find, for each person, the period of time (with a start and an end date) during which their test was below 50. The dataset looks like:
ID + LabID + LabDate + Result + Undet
----+------+-----------+-------+------
101 + 21 + 1/1/2000 + 780 + 0
101 + 21 + 2/2/2000 + 320 + 0
101 + 21 + 3/3/2000 + 50 + 1
101 + 21 + 4/4/2000 + 50 + 1
102 + 21 + 6/6/2005 + 1000 + 0
102 + 21 + 7/7/2005 + 900 + 0
102 + 21 + 8/8/2005 + 50 + 1
103 + 21 + 9/9/2005 + 50 + 1
103 + 22 + 9/30/2005 + 567 + 0
What I need is a query that produces the following:
ID + StartDate + EndDate
----+-----------+---------
101 + 3/3/2000 + 4/4/2000
102 + 8/8/2005 + 9/9/2005
I can also provide an attachment with more data, if that would help. Thanks in advance,

I have this table that records sales events for properties, with multiple sales records for some parcels. Each parcel has unique field: MapTaxlot. I want to create a select query or make table query that shows only the most recent sale event for each parcel. Instrument_Date is the date field for the sales records.
See attached example of the data table below.
What is the simplest method to accomplish this?

I am trying to open a form with some records taken from one table, then alter couple of data in it and after that most importantly to append current records into a different table. The reason I need to append is that I need to keep track on every occurrence on same fields.
It looks like this:
SerialNumber(Field 1), ServiceDate(Field 2), ServiceEngineer(Field 3)
Now suppose same serial number called again and asked for service, I need to still keep record on how many times this same serial number had service.

Somebody please help me!!!
I am creating a database that will record the details of approx 30 shops and will store information on Annual Turnover, Profit, Return, etc.
I need to create a field that will calculate the increase/decrease in annual turnover between the current year and the previous year.
So far I have created a subform that will show the last 12 years of data for the particular shop, but now I need to add a calculated field that will get the current years turnover and also reference the turnover for the previous year, i.e. the previous record., and display the result. The other thing that I will need to do, is to have this field not calculated for the initial years trading, so this field will need to be hidden in the first record.
Can someone please offer some advice on how to go about achieving this???

I have a table (tblStats). The user enters his current weight in a field named Wt. There are 2 other fields in the table named WkLoss and TTDLoss. These two fields are intended to be calculated. What I am trying to do is when the user enters his current weekly weight figure into the Wt field, I want the field WkLoss to get the user's weight from the previous record and place the difference in the field WkLoss. Also I would like to keep a total to date in the TTDLoss field.
So far this has been my attempt.
Code:Public Sub setWeight()Dim rs As DAO.RecordsetDim Startval As DoubleStartval = 190Set rs = CurrentDb.OpenRecordset("tblStats")'Select records to be updatedSet rs = CurrentDb.OpenRecordset _("SELECT * FROM tblStats ") rs.MoveFirst Do rs.Edit'field to update rs.Fields("WkLoss") = Startval rs.Update rs.MoveNext'increment step value Startval = WkLoss - Wt Loop Until rs.EOF rs.Close Set rs = Nothing End Sub
All I get is the value 190 placed in the first record and all zeros in the subsequent records. Also I don't have a clue as to how to get the Total To Date field to calculate.
Any help would be appreciated
Thanks for your time.

I have two forms both with separate tables
(1) Register and
(2) Payments.
One of the common denominators between them is the URN which is auto-populated as it is an auto number field. My issue is that when I want to add a new record to the payments table using the forms (I can get to the payments form via the register form), I want to be able to identify the record that I am currently viewing within the register and auto populate the URN field with the same number. This is what I have done so far,
Option Compare Database
Option Explicit
Private Sub AttachPaymentDetails()
Call PerformInsert("tblFinancialBudget", "frmFinancialBudget")
End Sub
[code]....

I'm trying to make a form that shows what the last record was next to the empty space where you enter a new record.
This is so the user knows that what they are entering is roughly in line with what has come before.
So for example if I was recording temperature every May, I would like a form that has a field called temperature and next to that field I would like to see last year's temperature.
Records:
Date | Temp
2014 | 20.5
2013 | 18.5
2012 | 19.0
2011 | 22.7
2010 | 15.2
So when I enter the record for 2015 I have a box that says: Temp and next to that box is "Last year was 20.5" or something like that.

In my query, i want to automatically display the value of another field from the previous record in a field in my current record. i.e.
Name Value Previous
Record 1 1
Record 2 2 1
Record 3 7 2
Record 4 1 7
Is it possible to create some kind of simple expression to refer to data in another record?
Cheers,
Ben

I have a query pulling data from two other queries (qry_Reports and qry_Surveys). Clients may have more than one ReportID, but only one ClientID. I need to query for only the most current ReportID (which is the larger value) for each client to find the surveys for the most recent report. How can I query for only the most recent report for each client based on the highest value of the ReportID per ClientID?

Hi all,
Another problem bothering me. Wish someone can help me to solve it. I am doing the 'Edit' Option right now ... As a user friendly propuse, I had try to use a combo box to let user to choose my employee record with all the detail on but the problem is the program 'JUST' list the record they can not go to the current record!! When i try to edit my record, the program is not allow (for sure because they can't have a duplicate record on it). The reason is because the record just stay in the FIRST record but can not go to the current record. I do believe is the problem of i using the way of listing the record as below:
Me.EmployeeName = Me.EmployeeName.Column(0)
Me.IC = Me.EmployeeName.Column(1)
Me.Nationality = Me.EmployeeName.Column(2)
Me.Race = Me.EmployeeName.Column(3)
Me.Sex = Me.EmployeeName.Column(4)
Me.FMU = Me.EmployeeName.Column(5)
Me.Position = Me.EmployeeName.Column(6)
Me.SectionField = Me.EmployeeName.Column(7)
Me.DOEmploment = Me.EmployeeName.Column(8)
Me.DOResign = Me.EmployeeName.Column(9)
Me.Remarks = Me.EmployeeName.Column(10)
So, Could someone help me to solve it like when i can use the combo box to select the Employee record with the details are on as the same time can go to current record... Thanks alot!!!
i do have the confident if i can go to the current record then my edit option can be working properly.
P/S: I had attach the picture... showing my program problem (with the red circle)

I have a table called tblFinishedGoods. There are 3 fields in the table:Serial Number, Model Number and Location.
I would like to have a form that will take input from my barcode reader and input the data for the 3 fields, if the serial number is not already in the table.(I have this already working).
But now I would like the same form to also check the table for any serial number that is scanned in...and if it is in the table already, have it bring up the model number and location for that record.
I'm thinking maybe there is something I can do with Serial Number afterupdate. Basically I'm looking for a way to not require the user to input anything via a mouse or keyboard.
If the 1 form could accept the 3 scans:Serial Number,Model Number and Location, and either 1)enter a new record if that serial number isnt in the table or 2)find that the serial number already exists and overwrite the model number and location with whatever the next 2 scans are.
Thanks

hello,
I have faxing setup through the XP wizard, I setup my report in Access to use the Fax as specific printer. So When I select a record, it generates the Fax wizard which then prompts for the senders name Fax # etc. and away it goes.
that is ok but It would be nice if I could use the Fax number from the record I am sending, either current record or all. I guess the main trick is how would I pass the fax number to the Fax Printer interface?
Is it possible? I've read a few articles on Microsoft Fax for workgroups to work with Outlook, Outlook help says to go to Office update and download it but I can't find it there? Also do the newer versions of Outlook/Access have a better means of doing this? I am running office 2000, but I can get 2002 installed if that is the case.
thanks

;) Hey everybody,
I am working on a database used in recording device characteristics/test information. The main table of information has dozens of columns for test/part detailed information. When inputing the data for each specific test, many of the info. details are repeated when testing say 20 devices of the same part all at once. Rather than retype every piece of detailed information in every field, everytime, is there an easier way? Does anyone know of a way to make specific fields copy/paste the previous record's information in the fields automatically when a new record is created? Please, if anyone could help or has ANY ideas, let me know...
Thanks

I've been asked to get some information from my database and I'm a bit stuck.
I have a list of refunds in tbl_main and each one includes a dateReceived. I make a record in either tlk_located, tlk_unableToLocate or tlk_bulk depending on the outcome when we're trying to send the money back to whoever it belongs to. Each table has a time stamp (named locatedTime, unableTime and timestamp respectively) field
My manager wants me to report how many entries were unworked on each day in the year, and what the value of them was. An entry is unworked if there is no entry in either of the 3 tables.
So I need a query that lists a range of dates, and for each date counts the number of entries where tbl_main.dateReceived is <= to that date and either has no record in located,unable or bulk or has a record with a timestamp > than the date. (It has been processed now, but hadn't been on the date we are looking at)
I can manage a query that looks at a certain date that it prompts for on each run:
Code:
SELECT Count(tbl_main.trust2PK) AS CountOftrust2PK, Sum(tbl_main.amountRefunded) AS SumOfamountRefunded
FROM ((tbl_main LEFT JOIN tlk_located ON tbl_main.trust2PK = tlk_located.trust2FK) LEFT JOIN tlk_unableToLocate ON tbl_main.trust2PK = tlk_unableToLocate.trust2FK) LEFT JOIN tlk_bulk ON tbl_main.trust2PK = tlk_bulk.trust2FK
WHERE (((tbl_main.dateReceived)<=[cutoffDate]) AND ((tlk_located.locatedTime) Is Null Or (tlk_located.locatedTime)>[cutOffDate]) AND ((tlk_unableToLocate.unableTime) Is Null Or (tlk_unableToLocate.unableTime)>[cutOffDate]) AND ((tlk_bulk.timeStamp) Is Null Or (tlk_bulk.timeStamp)>[cutOffDate]));
I would like a query that lists all dates in a range, and shows the same information for each day listed.

After I enter data into one field in a record I would like the form to save the record when I move to another field in the same record. It seems that the record is only saved when I exit it entirely. Is there a way to save a record when moving between fields in that record? Can this be done without using an Event Procedure for each field?
