Queries :: Calculations With Values In Previous Record(s)
Jan 12, 2015
I have a database where I need to record student data, specifically marks and absenteeism. The marks are recorded each term as a running total. I have a final mark which needs to be equal to the 4th term mark.
I also need to record the number of days absent each term with a total at the end of the year.
My problem is that the term 4 mark is a in the previous record and the total days absent needs to be the total of the previous 4 records (term 1 - 4).
I using a create table query and an update query but that was a no go.

I have partially done it using PrevRecVal module I found on the web.
I created what I need to do in Access in Excel first, the problem doing this in Access (for me) is I need to refer to the results in the previous record, PrevRecVal worked but I need to finish if possible.
The main report holds client policy data of which InvestAmount is used to start the calculation of the sub report, the data entered to run the calculations on the subreport would be
QtrDate
CurrentUnitPrice
The Excel spreadsheet is attached ....

I have a query that I run to extract some values for calculations. Its run on an event based on a dropdown selection. At the moment, I run via:
Code:
DoCmd.OpenQuery "CallMidprice"
and then close it. this seems to take more time than is necessary when I only want to refresh the results.Open query without close, switches to the table but doesn't update until I press F5.When I try requery I get an error. "Runtime error '2109': There is no field named 'CallMidprice' in the current record.
Requery without 'Callprice' seems to requery my form.

How might I go about taking the values fo certain fields in a previous record and place them in the same fields of the current record, using either a query or VBA?
I've seen something about being able to utilize previous record data but for the life of me I can't remember where I saw it!!
Any help is appreciated.

G'day. I've been browsing the forum trying to find a solution to a problem, without much luck, and am hoping that someone might be kind enough to help me more directly.
I'm a biologist and a newbie to access: with the distinction of being completely clueless about VBA. Nonetheless, I have been tasked with creating a database for storing data obtained from biological surveys of juvenile salmon and harvest/spawner surveys of adult salmon.
The bones of the db are in place and functional. The problem I have is streamlining the data entry process to minimise keystrokes/mouse clicks.
I have a subform for entering fish records with attributes such as 'species_name', 'fork_length', 'count', 'presence of tags, etc. The idea is that fish can be entered as individuals (count=1) or groups (count>1) with attribute data at the appropriate level (eg, fork lengths only entered for individuals. We typically measure the fork lengths of the first 20 individuals of each species and then tally the remainder).
One problem I face is that fish often occur in schools, and it becomes quite tiresome to click and select the same species_name combo box value for each record when entering multiple individuals of fish of the same species.
What I would like to do is set the default value for that combo box (on the fish subform) to match the value entered for the previous record.
I suspect that you could use the after update trigger to execute some code to change the default value each time something is entered manually into the combo box. Unfortunately, I know nothing about how to write the appropriate code.
Can anyone offer me some guidance?
Thanks in anticipation.
Sincerely,
Craig Dolphin

I have a Contacts subform and would like to be able to double click to fill addresses, and details from the previous row...every person in our database even those living at the same address needs thier own record.. and since we only need to fill up to 5 records and review them, double clicking on the first name to fill up the next row with the previous addres phone number ect would be grand.
I am assuming we could fill out the new Full Name and double click on it to get the previous record filled to the new one. Don't really want to work with a query unless needed, but I have a little vba understanding.. how do I code this to make it work?
Full_Name_Dbl_Click
getPreviousRecord.Address(-1)
getPreviousRecord.Phone Number(-1)
getPreviousRecord.City(-1)

In my database scenario, a patient would see a doctor and the doctor would check off fields in a form representing different disease symptoms that the patient has to calculate a final score (for ex. if the patient has 2 symptoms, the final score would be 2).
After a few months, the patient would visit the doctor again, and the doctor will have to fill out the same form, adding any new symptoms the patient might now have. I would like to have the disease symptom fields checked off in the previous visit automatically show up in the new form, so that the doctor only has to add the new symptoms, and then recalculate the score using both the old and new data (for ex., if the patient had 2 symptoms before and 3 more symptoms now, the score would be 5).

I wanted to auto populate an invoice record with same values as previously ordered by that same customer. I don't want to use default values as every customer orders different things.
BUT almost all customers make REPEAT orders of exactly the same things they ordered previously.
So...for example, can I search the invoice records by customer ID/Name and copy all the data from their previous into a new invoice record. I guess I could do this with an append query?
But will an append query run when I just click on 'new record' in the invoice form? Maybe there is a property '.on new record'...open append query....?

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 to add two previous record fields together in a query. I have attached a picture to illustrate.
The "StudyYears" filed is the primary key of the table the data is being pulled from. The zero's are placeholders for the sum of the previous record's data.
RunningBalance is calculated as follows:
Code:
RunningBalance: IIf([a].[StudyYears]=[ReserveParameters]![StartingBalanceYear],CCur([ReserveParameters]![StartingBalance]),0)
Bal is calculated as follows:
Code:
Bal: [AnnualContribution]+[InterestIncome]+[Inflation_Adjusted_Expenditures]
How to go about adding the two together as in the picture?
Is there a way to do this relatively fast, as well as keeping the query updateable?

How do you compare one record to the previous record? I have a query that shows items sold. It is sorted by day with today on top. I would like to create a column that has a 'thumb up' or 'thumb down" if todays was a better day than yesterday.

I have a table that will have ITEMID as unique field but location could have save values. I tried using DLOOKUP to look at the value for the previous record to see if I need that value is same as current, however, since my data query are text formats, I am unable to. I get a message of mismatch data type. apply my query to look at sorted table by Location and ITEMID and if previous location = location, then my area=0?

I've got stuck in preparation of this sales query. The primary sales table contains a mix of Canadian and the US detail invoice sales records. All sales records are in their native currencies The secondary lookup table contains daily US/CAN foreign exchange rates (FX).
I need to multiply every $US sales record (marked with U) with the FX rate in order to convert it to the Canadian currency. Unfortunately, this FX lookup table is missing over 50 daily rates in the last two years and as a result I cannot match them date-by-date with the sales table.
As a workaround, it is acceptable to use the previous FX rate in the table. The previous rate can be one or more days before the transaction occurred.
Attached is a sample database with the query that I've already built. The query contains two sample US records that are missing the FX rate on Jan 6. The FX rate of $1.0639 that needs to be applied to it should come from Jan 3rd entry.

I have a form that is used to book a new event for a client who is already in the database.Within that form I have a subform that is based on a query which displays information from that client's previous event. I did this using a solution found in the following thread: URL...It is based on pulling the second to last record that is related to the current client. It works perfectly when booking a new event that has taken place on a previous date. However, if the previous event occured on that same date (but at a previous time), it doesn't register.
I would prefer a query that would pull the record previous to the current one, instead of pulling the second to last record out of all that client's events.it would also mean that if more events are booked, then a past event is opened in a form, the sub forms in that form will display the event just prior to the current record.

I'm trying to refer to previous record in a query and i'm stuck as i do not know how to do it.
Here is my query:
Code:
SELECT
[Prod2Buy].[Product Code],
IIF([Missing] IS NULL,0,[Prod2Buy].[Quantity To Order]-[To Order]) AS [Rest To Order],
s.s_manu_code AS [Manufacturer Code],
s.prod_cost AS [Price Code],
[Code] ....
In fact the line: IIF([Missing] IS NULL,0,[Prod2Buy].[Quantity To Order]-[To Order]) AS [Rest To Order] should refer to previous record.

Help!
I have a database that records all procurements and requisitions of our medical supplies.
I have set up queries that sum all requisitions in a set time frame for each item that should be in the store (i.e. this month, this year etc) and similar query for the procurements.
A further query then subtracts the requisitions from the procurements and (should) give me an inventory of all medical supplies.
BUT.....
If no items have been procured or requisitioned, they are excluded from the sums. We have a standard list of items (which is a table in the DBase) and I need to know if we have no stock (there are certain things we can't get all the time in Tanzania, so procurements and requisitions are zero/nul for a while and I need the Dbase to highlight the lack of items).
Please help!
Note, if there is away of doing this with out VB I would be very happy as I have never used VB and it terrifies me.

eaten by Mike and Peter together and ignore John and Phil?
Question 2:
How can I get sum totals for everybody excluding just Peter? Or Peter and Phil?
Your help will be very much appreciated!

Hi Everyone! Bear with me, I'm new to Access and I may not understand or use all the terminology correctly.
Background: I'm creating a database to track the inspections of many businesses. Each business will have many inspections throughout the year and each inspection has many items. I have a form set up which includes Business info and Inspection info (#items inspected, subtotal for inspection) on the main form, and Items in error listed on a subform (no error=no items listed).
Problem 1: I need to make a count of all items that are listed. I can do this in the subform, with no problem (in one of the footers #Discrep:count([item])) but now I need to report and use that value on the main form to calculate the percent error for the entire inspection. I don't know how to pull in onto the main form to set up my calculation. :confused:
Problem 2: This one is related and is probably the same fix. I have PriceCharged and PostedPrice for each item. I need to calculate the net error and then, using the subtotal on the main form, calculate the % dollar error.
Any suggestions, oh great and powerful gurus of the Access world? I hope I explained that clearly enough for you.
Thank you very much in advance!

Hi,
My boss wants me to program in visual basic, instead of using queries, a calculation between times, which values are gotten from a table. How do I perform a calculation between two fields from a table in code and what functions are there to calculate the amount of difference in minutes between times in visual basic? THANK YOU SO MUCH IN ADVANCE!
