I'm trying to make a query where it can calculate the difference between a table field value and a query field value.
Ex. Table INVOICE - fields
invoice no, invoice value,
Query TOTAL - fields
invoice no total invoice value
I need to get the difference between invoice value and total invoice value.
How can I put this into a query (invoice value - total invoice value)?
I have a query that must calculate the different between values in two different records, based on the date.
The underlying ORIGVALUES table contains:
Date; Value; Diff
1/10/15; 100; (this is what I am trying to calc)
1/11/15; 101; (this is what I am trying to calc)
1/14/15; 102; (this is what I am trying to calc)
What is the best way to have each record calculate the selected date value divided by the prior date value)? E.g.
For 1/11 the math is 101 / 100 (so the 1/11/15 record would show the result of 1.01)
For 1/14 the math is 102 / 101 (1/11 to 1/14 represents a weekend)
I could copy the prior day values to the current day records and do that math easily but that is very redundant.
I have a list of client activity - client name, loan ID and loan date. I would like to create a new field that shows the number of days between one loan and the next. If I was doing it in excel, I would need to sort the data by client name and loan date and then calculate the number of days between the loan date of one loan and the loan date of the loan immediately prior to this.

I need to work out the number of hours. I have two date/time fields Day_Start_Time and Day_End_Time. I want to calculate the difference between the two in hours and then multiply by the number of working days.
I tried this: Number_Of_Hours: DateDiff("hh",[Day_Start_Time],[Day_End_Time])*[Number_of_days]
But get #Func! when I run the query.
I'm trying to work out the difference between 2 records both of which have a call out date [bas start date]..basically the structure is
equipment number call number bas start date
12345678 112255 1/7/14
12345678 112256 3/7/14
What i'm after is the 4th column to work out the date diff... in this case 2 days the equipment can be multiple times so i might see equipment number 12345678 - upto 10 times with consecutive dates - all of which i need to know the difference between the current call date and the previous call date..
In access in one field I have one date and in another field I have another date. I want to calculate the number of years.,months and days elapsed between these two date. e.g. suppose in one field I have 30.06.2005 and in other 20.04.2004 then it should show 1 year 2 months and 10 days.
View 14 Replies View RelatedI'm trying to create a database for a Cattery business.
One thing I'd like to include is a query that calculates how long a cat has been staying at the cattery and then calculating the amount owed by the owner.
I don't have a cost field in any of my tables, so I need to create this on every run of the query.
So for example
A Cat resides in the cattery from the 22nd of Feb to the 28th of Feb. So 6 days (not including the day the cat is brought into the cattery) at a cost of 4.95 a day equals 29.7
Heres what I have so far

Any help will be greatly appreciated.
Hi, I wonder if someone can help me with the following problem:
I have a table with 2 columns,start time and end time, both containing time values in a four digit format, eg 0930 being 9:30am etc.
I have made a query to convert these into the standard format (eg 0930 becomes 09:30), using left/right and & functions.
Now I use the timevalue function to convert the string , eg 09:30m into a recongnised time value.
The problem is now I want to find the difference between the start and end times- but when i try a simple end_time - start_time formule it returns a long number which i dont understand, rather than just giving me the difference betwen the two times.
Im sure there is a simple way to do this which I dont know, can anyone help me out? Thanks in advance!

I need help to calculate time difference from the record above where ID is same. I have attached an example in excel with this request where I have if statement doing exacly what I want to do in Access. I have a table in Access that has three columns - as below
ID, Reg, TimeDiff
66646, 14/06/2007 21:33,
66646, 15/06/2007 06:03, 8:30:00
66646, 15/06/2007 12:20, 6:17:00
66646, 15/06/2007 15:08, 2:43:00
67844, 14/06/2007 04:39,
67844, 14/06/2007 09:05, 4:26:00
67844, 14/06/2007 09:08, 0:03:00
67844, 14/06/2007 16:27, 4:09:00
If ID is equal to the ID in record above then TimeDiff is equal to reg minus reg in the above recored, else blank.
Hope someone can help me with this.
Thanks, GS
I currently have a table that has patient ID (unique record (SSN)) and a date of visit field. The SSN may have numerous rows with different dates of visits. What I am trying to do is a DateDiff function that will retrieve records that are 48 hours apart or 2 days apart. We are tracking patients that return within 48 hours of a previous visit.
View 10 Replies View RelatedI have created a database in Access where parents of students may come in and volunteer and receive free time credit from their employer (those companies who participate).
The database runs fine: Main table (demographics; student table; signIn/signOut table; and Volunteer Duty (a combo box that list all of the approved volunteer duties to qualify for the time credit) Every thing works perfect with the exception of my signIn/signOut form. After struggling with this for countless hours, I have settled for a manual entry of the signIn and signOut time, entered at the time of their start/stop times. I would like for it to be an automated function, but I have had such a difficult time up to this point I will settle for this method. What I NEED is to figure out how to make my "total vol hours today" field calculate the total volunteer hours at the time the parent "signOut".
If some of you Access MVP's can help with this I will be very grateful.
I awaite your answers, and THANKS IN ADVANCE.

Hi, I am a longtime Excel user, and am now migrating some work to Access.
I have 2 fields dealing with dates in the format mm/dd/yyyy hh:mm, OPEN and CLOSE
I'd like to get the difference between the two in hours, but I have no idea how or where to do this in Access. I'm assuming it is put into the queries, but it would be easier if I could just put it in the table.
Here is an example
1/1/2008 1:00 1/2/2008 2:00
I want the result to be "25"
Thanks in advance!
i have a access table (AUTH) with following field
Company Auth Held
Tata 12
Dell 11
HP 21
Opera 11
Bangour 10
i used the following query to calculate the Held from a table named pers.
SELECT AUTH.company, AUTH.Auth, Count(AUTH.company) AS Held
FROM pers INNER JOIN AUTH ON pers.company = AUTH.company
GROUP BY AUTH.company,AUTH.Auth
then i got the result as under
Company Auth Held
Tata 12 02
Dell 11 08
HP 21 20
Opera 11 12
Bangour 10 12
now i want the difference between Auth and Held as Sur/Defi
how can be it done.
I am VERY, and I mean VERY new to Access. I've been racking my brain all afternoon and googling like crazy. I just completed two levels of training on Access 2010 and have never worked with the program before. I already set up my tables and now I am on to querying. I have a table with several columns, two of which are "Start Time" and "End Time". I already created a query using the DateDiff function to calculate the time difference for each record. It output a new field with the time difference in hours. Now, I want to sum the totals of the time differences by month and I cannot for the life of me figure it out. My new query has Date (m/dd/yyy) and Hours.

Is there a way to calculate three different rolling averages in one query?
I just inherited a database where someone is using three queries to capture the same information only with different time frames. They were calculating a rolling three month average, six month average, and twelve month average. I would like to combine these queries into one to reduce time spent running reports from the database. All three queries are based on one table. One of the columns in that table is called "Month Start Date". That field shows the first day of the month when a call was entered. I can get the query to tell me the first month in the three month period and the first month in the six month period, but I can't get it to calculate the averages of the calls that fall in those time frames. Here is the SQL for the query I have now. When I try to run this, I get the error message that my formula is not part of an aggregate function.
Code:
SELECT DISTINCT DateAdd('m','-2',(Max([Month Start Date]))) AS ThreeMonthStartDate, DateAdd('m','-5',(Max([Month Start Date]))) AS SixMonthStartDate, Max([Month Start Date]) AS MaxStartDate, IIf([Month Start Date] Between [ThreeMonthStartDate] And [MaxStartDate],Avg([All Call Rate]),' ') AS ThreeMonthAverageCallRate, LIST_WITH_TNC.Device, LIST_WITH_TNC.Model, LIST_WITH_TNC.[Item Num]
FROM LIST_WITH_TNC;
Is there a way to make this work?
I have been working on a stock database for my company. It needs to hold stock data, Any adjustments in the storesperson may do (QtyIn or Out). And allow Customer PO's to be raised (just to show prices and quantites sold to customers)
I have 4 Tables:
tblStockList
PartNumber (Primary Key)
Description
Location
StockCheck
StockListUnitPrice
[code]....
I then want to create a query to work out the total stock.
At the moment i have two queries, one to Sum the adjustments and one to sum the PO's. (The stock is not removed from the Customer PO until invidual line is shipped)
I then need to combine both these queries to work out the total stock value.
There will always be a value in the Sum of Adjustments but not in the Customer PO. So when i run the query to =SumofAdjustments - SumofCustomerPO's, if there is no record in the SumOfCustomerPo's, no value will appear.
My training database requires me to identify each training record in the tblEmpTrainHist table as either "Compliant" or "Delinquent". I thought a simple calculation in my query:
RecordStatus: IIF([DateReceived]<=[DateDue],"Compliant","Delinquent")
would do the trick. However, I did not consider the records where the employee has not yet completed the training and the field [DateReceived] is Null. There are two considerations: those employees who have no [DateReceived], but have not yet reached the DateDue (Compliant); and those employees who have exceeded the DateDue (Delinquent).
I'm making a query that has the following Fields
Product (Table PDZRN1)
Whse (Table PDZRN1)
Description (Table PDZRN1)
On Hand (Table PDZRN1)
Unit Cost (Table PDZRN1)
Unit Price (Table PDZRN1)
LastDate: Date (Table Sales_History) (using the Max function)
Where I am stuck is I want 4 additional columns to pull the last 3 fiscal years and total sales for each Product for the 3 previous fiscal years. The Field with sales amount is "Sales" it is located in Table "Sales_History", and the dates for the invoices are in the field "Date". I tried the following query, but I'm sure it didn't work because I failed to push the data back to the date field:
Field - FY2013Sales: Sales
Table - Sales_History
Total - Sum
Criteria - <= 04/01/2012 and <= 03/31/2013
how to link my criteria back to the "Date" field, or if I'm even going down the write path.
I don't use Access too often but I'm trying to connect a table to some business intelligence software I use.
A. Date B. Price C.Ydayprice
01/01/2015 101.45
02/01/2015 104.70
03/01/2015 103.00
Simple stuff. Once I've connected to the table, I can easily do what I want with Field 'Price' and 'Ydayprice'. However, I can't calculate column C. All I want is row 2 to say 101.45, R3 to say 104.7 etc. I've tried various things but I don't have the knowledge to write the action I require. I don't want to calculate the change in Access either.
Hi, I'm a total newbie at Access, and know nothing about scripts. I've been operating at the level of using the Wizards and drop-down menus. I am trying to create a report that does two things:
1. Displays the results of queries that sum data from a table (I think I have this figured) and
2. Displays those sums as a percentage of a number that is input each time the report is run. (This is only one number that comes from a totally different place and has no prior relation to the data.)
Any help/advice that anyone could offer would be much appreciated!
Thanks!
