How To Compare Time Values?
Nov 15, 2007
Hi.
I need create a query that can compare different time values.
My time field format something looks like 12:59 PM.
And compare other fields that has +- 10 minutes from my input.
It means when I input 12:00 PM to the query inputt then it lists records that have times 11:50 AM and 12:10 PM.
But I don't know how to compare these..they are not natural numbers..but they aren't text niether..
I tried to do it
[Arrive_Time] + 10
[Arrive_Time] - 10
in the criteria..but..doesn't work.

Any idea if there's a way to compare values between two subforms on one main form?
I have a Required Inventory and and an Actual Inventory subform. I want the Actual Inventory field to be conditionally formatted to turn red if it is less than the corresponding required field and green if it is more. I know how to use Conditional Formatting, but I don't know how to reference the values in the next form.
Note: I have no problem using conditional formatting compared to values in the parent form. The syntax I used for that was:
[Forms]![frmMain]![txtControl]
But still no luck referencing subform controls.
Thanks.

I need to compare the sum of a values in a column of rows with the same id. For example:
Code:
ID Value1 Value2
122222 20 40 (these are okay, the sum of Value1 in rows with same ID equal value 2)
122222 20 40
333333 100 100 (ok)
111111 50 100
111111 50 100 (not ok, the values with same id add to 150, so the first row containing this id should be deleted so the the total of Value1 equals Value2)
111111 50 100

Hi there
This is probably quite easy but I cannot make it work so would appreciate some help. I have a table containing vehicle information. I have 2 fields, Current Mileage and Max Mileage. I want to do a comparison of the 2 fields and should the Current Mileage be greater than the Max Mileage, the query returns the Vehicle Registration. Test data has been entered in the table I am querying and I was expecting 1 value to be returned. However the query as I wrote returned either all the vehicle Registrations or none of them. Can someone help with this please.
Thanks in advance for the assistance
Craig:)

Hi,
I am trying to compare two columns' values within the same QUERY table, but I kept on getting the "Data type mismatch in criteria expression" error. What am I doing wrong?
Here is my Select Query Statement:
SELECT qryDedparmDedetail.EMP_ID, qryDedparmDedetail.[Employer Amt], qryDedparmDedetail.[Employer Actl], qryDedparmDedetail.[Admin Amt], qryDedparmDedetail.[Admin Actl], qryDedparmDedetail.[Employee Actl], qryDedparmDedetail.[Employee Amt], qryDedparmDedetail.FirstOfSTATUS, qryDedparmDedetail.FirstOfAGENCY, qryDedparmDedetail.FirstOfTITLE, qryDedparmDedetail.FirstOfFORMAT_NM, qryDedparmDedetail.RepUnit, qryDedparmDedetail.FirstOfDEDTYPE_CD1 AS Expr1, qryDedparmDedetail.SumOfNBR, RepUnit.REPUNITDESC, qryDedparmDedetail.LeftType
FROM qryDedparmDedetail LEFT JOIN RepUnit ON qryDedparmDedetail.RepUnit = RepUnit.REPUNIT
WHERE (((qryDedparmDedetail.[Employer Amt])<>"Employer Actl") AND ((qryDedparmDedetail.LeftType)="01"));

I would like to compare the values of several columns in the same record and remove any duplicates. So...
ID | Col1 | Col2 | Col3 | Col4 | Col5
-------------------------------------------
1 | A | B | C | D | C
2 | C | C | C | D | D
3 | A | A | B | A | D
In the above example I would remove one of the Cs in row 1.
Two Cs and one D in row 2 and two As in row 3.
At the moment I have the value of each column stored in a variable and each one is compared against each other using LOTS of If statements.

Table 2

The result of the query should show me
A4 (as this does not appear in table 2
I am not too familiar with Null values as there will be many null values that i want to ignore.
Any help will be appreciated.

I am building a tracking database where we would be able to track information which field are null data and report them to our Administration to fill the null data. For this I have created a form name "Search" and I have a combo box control on that form which is bound to "Table = employee" and its ROW SOURCE TYPE="Field List", I would like to able to query records where the selected value in this combo box is null through out the table.
For example if I select "Telephone" from this combo box dropdown, I would like the query to show all the records where the "Telephone" is null, how to set the criteria in query to take the combo box value as "Field Name" and then compare it with the Field/Column in the table and show the null values.

I have a travel time database that should tally the number of minutes traveled and convert them into a time (hours and minutes). I, however, am having difficulty converting the numeric values cleanly. Is there anyway to convert 102 minutes + 100 minutes + 110 minutes = 312 minutes to 5 hours and 12 minutes cleanly? I need to take averages of time traveled and hours worked but cannot do this correctly. Thank you for any help in advance.:eek:

Hello again,
I think my subject heading explains it. How would you add or subtract two short time formatted values and produce a short time value? Also, how would you change a short time value into number minutes. (i.e. 5:30 into 330) Thanks!

Need some ideas on how to detect if Time Now is beteen preset values.
It is in connection with a Machine Monitor system being I am probably going to be asked to develop.
Problem is night shift. They work normally 20:45 to 06:45 following morning
I will be accumulating elapsed minutes of shift and working minutes by running an On Timer event updating both values by 1 each minute providing certain criteria are met.
One of the criteria will be that machine is supposed to be working.
So I was planning to set a flag indicating Working Yes or No based on the Time Now being between start and end times.
This is fine for normal day working and normal day shifts but is a problem with Night Shift.
Ideas on how to handle welcome

I Have a problem in which when I create a record I wish the record to automatically record the time it was created. I have achieved this by having a timerecorded field within the table and setting its default value to time().
later on I wish another time to be recorded. This time when the user selected an option box to -1 I wish the time to be stamped into another field. I have used this event procedure to write the time to another field.
Private Sub AOGCleared_AfterUpdate()
'Update Time
If Me.AOGCleared = -1 Then
Me.TimeAOGCleared = Time()
Else
Me.TimeAOGCleared = ""
End If
End Sub
however It records the original time of creation when the obtion box is selected. Can anyone please point me in the direction of how I get access to record this later time please ?

Hi:
I try to get the value in a real time. There are two subforms inside a mainform. First user enters value into mainform. Than comes to subform1. And after that on the basis of a choice in subform1, the 2nd subform is open. In 2nd subform i create a listbox with that query.
SELECT [tbl_Events].[PPVVOD_Outlet] FROM tbl_Events WHERE [tbl_Events].[ticketnum]=[Forms]![tbl_PPVResearch]![ticketnum];
But it shows empty. [tbl_Events].[PPVVOD_Outlet] is a subform1

Hi all!
This is kind of a philosophical question :)
I’m doing some changes to a “CRM”-database, and need to make a function that changes values in several records in one operation. The problem is, I have now idea on how to approach this problem.
One example; I have made a simple invoice function in my db, which works well. But now I send a lot more invoices then when I made the function. I’ve made a form, which prints the invoices, and I can print several in one “operation”. How can I, in the same operation, also change the status of the invoice record so that it says “Printed”?
If you have any suggestions on the method e.t.c.? Thank you!
(I'm using Access 2000)

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!

Hello all, I am trying to dispay results in a query which is based upon time.
e.g.
Sample data - class and class start time
Class one - 7pm
Class two - 7pm
Class three - 7pm
Class Four - 8pm
Class Five - 8pm
Class Six - 9pm
Class Seven - 9pm
Class Eight - 9pm
Class Nine - 9pm
If i was using the sample data above and the time was between 7pm to 8pm i would like to show only the classes which started at 7pm, or if the time was 8pm to 9pm, only show the classes which started at 8pm and the same for 9pm
I hope i have explained myself clearly, and I will be thankful for any help.
Thanks

Dear All,
once again I need your help, I have no idea how to tackle the following problem. I am taking records of stock market transactions. As a final result I want to have a query which gives me for every end of the day the total value of my portfolio.
Therefore I have two tables. The first one, called tblTransactions with columns - among others - Date, Ticker, Quantity, Price does contain my transactions. The second one, called tblQuotes with columns Date, Ticker, LastPrice contains prices for each security traded for every day.
The following SQL code gives me the portfolio holdings with the respective LastPrices on an arbitrarily chosen date (03/09/07):
SELECT T.Ticker, sum(T.Qty) AS TotQty, Q.qCl AS [Last Price], (T.Qty*Q.qCl) AS [SubTotalValue]
FROM tblTransactions AS T INNER JOIN tblQuotes AS Q ON T.Ticker=Q.qTicker
WHERE T.Date<=#3/9/2007# And Q.qDate=#3/9/2007#
GROUP BY T.Ticker, Q.qCl, (T.Qty*Q.qCl)
HAVING sum(T.Qty) >0
ORDER BY T.Ticker;
This works so far. However, now I struggle with the next step. I want to have a query, which for each date (I could use the date column of tblQuotes) adds all SubTotalValues, i.e. gives me the total value of my portfolio for each day.
Could you give me please some hints on how to proceed from here? I would be very pleased if somebody could help me with that question.
Best regards

I'm trying to create my own database dealing with hiring bikes on a daily basis.
I have created a form for the basic input, including StartDate, StartTime, EndDate and EndTime, followed by TotalDays. I added the time field so that if a client brings a bike back an hour or two after the pickup time on a later date (sounds complicated - e.g he takes it on Monday at 12pm until Thursday 14pm) then he would be charged for an extra day. It is similar to the car rental system used worldwide.
The TotalDays is currently using a simple expression =EndDate-StartDate.
Is there any way to make the form incorporate the time difference so that if EndTime-StartTime>1 then it would add an extra day to the "=EndDate-StartDate" calculation.

I want to be able to display the result of a difference between Date/Time values in "HH.MM" format (i.e. yes I want the result in decimals and I don't want Access to round up or down just because it feels like doing it!). I have used the following:
Example 1:
Dim ActualManHours as Long
ActualManHours = (txtEndTime.Value - txtStartTime.Value) * 86400
txtActualManHours.Value = ActualManHours
Example 2:
Dim ActualManHours as Long
ActualManHours = DateDiff("h",txtStartTime.Value, txtEndTime.Value) & "." & Format(DateDiff("n",txtStartTime.value,txtEndTime. value) Mod 60, "00")
Example 3:
Dim StartTime as Double
Dim EndTime as Double
Dim ActualManHours as Long
StartTime = CDbl(txtStartTime.Value)
EndTime = CDbl(txtEndTime.Value)
ActualManHours = EndTime - StartTime
txtActualManHours.Value = ActualManHours
