Hi I have two fields one which represents the time participants went to sleep, one when they woke up however I dont have any dates - it refers to what they do usually. Is it possible to minus sleeptime from waketime to determine duration of time in bed without dates? Or do I assign dummy dates to use date diff function?
View RepliesI am trying to subtract 12 hours from a time-date field when the payperiod does not equal 01.
in a query I have:
work date: iif([payperiod]="01",[StartTime],[starttime]-#12:00:00#) - Access added a PM before the second hash so it looks like this:
iif([payperiod]="01",[StartTime],[starttime]-#12:00:00 PM#)
When I run the query I get a message box: "syntax error (missing operator) in query expression '00:00:PM#,2))". I am unable to open the query to correct the error. I can cop the unaltered query from a back up database.
My question is how do I subtract the 12 hours.
Thanks

Any Help!
I have fields that are time formated 99/99/99" "00:00;0;_ and I want to subtract them.
I need to get the results in two forms; first in Days and second in Hours. I have used the obvious subtract one from the other and it gives me days in a rounded numbeer, but the hours is not working out.:confused:

Before I start implementing this, I would like to know if it is possible to do in principle
I want two fields, say TimeStarted and TimeEnded. I then want to subtract the two from one another to see how long the task took.
Is this possible or would i be wasting my time trying it?
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!

Hello,
I am having problems creating a Exp to show the difference in time.
I am currently using :Expr1:DateDiff("n",[TimeReported],[TimeDefectGiven]) which is returning a figure in decimal.
If the answer was to be 90 minutes i need it to return the figure as 1.50 instead.
I have looked on the site using Date Diff and Time without success
Any help given would be great
I have a date field, I am trying to have my query only pull the records that have a date entry that is within and up to 90 days from today or Now. For this query all other records are irrelevant.
THis is what I have found so far
=(Abs(DateDiff("y",Now(),[ls_Exp Date])))
Can someone show me how to add the 90 days in there?
Thanks.

I'm using the date diff .... DateDiff("h",[Start time],[End time]) in a query and then I report the results in a report. I have run into a problem for the first time. I had a start time of 7:00pm, and an end time of 7:00am. This was calculated in the query as (-12) which is messing up my cost formula.
How do I resolve this?

Here we go:
My overall goal is to find out a worker’s downtime (count of weeks between assignments)
I have a qry_Downtime that pull in a worker and his current and future assignment. Each assignment is associate with a start and end date.
Here is how the results look:
Employee (joe schmo)ProjectONE ProjectONEStartDateProjectONEEndDate
Employee (joe schmo)ProjectTWO ProjectTWOStartDateProjectTWOEndDate
Employee (joe schmo)ProjectTHREE ProjectTHREEStartDateProjectTHREEEndDate
Employee (joe schmo)ProjectFOUR ProjectFOURStartDateProjectFOUREndDate
Downtime would be defined the diff in weeks between ProjectONEEndDate and ProjectTWOStartDate, ProjectTWOEndDate and ProjectTHREEStartDate, etc.
Any suggestions.

Friends,
I have a problem with a date diff calculation:
On my form I have placed two controls, a text box and a check box.
The textbox contains is a date field (mm/dd/yyyy).
What I need is a code that checks the checkbox if the date in the textbox is within the last 12 months.
This is the code I am using but not working:
If DateDiff("yyyy", textbox, Now()) >= 1 Then
Me.check1 = "yes"
End If
Any help? Thanks.
I am having a problem with a datediff expression.I have a query that pulls the first date and the last date out of a list but are put in seperate fields. I thought I could build an expression for datediff to calculate the number of dates between them. I can't just put in the dates because they are constently changing.The expression I have is:
[datediff("d",[min/max edging unit #2]![firstofupdate/time by month],[min/max edging unit #2]![lastofupdate/time by month])]
i have 2 tables.. 1 with bookings and 1 with a BonusPeriod range.
in the Bookings table there is a field called [ServiceDate]
in the bonus table i have a field called [Period] which is text i also have 2 dates, [StartDate] And [EndDate] i need to Dlookup the Bonus table to return the value of the period table based on where the [ServiceDate] falls.
i dont want to use VBA (i really need it to work within a query that inserts it's data into another table)
i've tried everything but had no joy
Expr1: DLookUp("[Period]","BonusPeriods","[ServiceDate]" Between "#[StartDate]#" And "#[EndDate]#")
Expr1: DLookUp("[Period]","BonusPeriods","[Staff_BookingsAndQuotes_Master].[ServiceDate]" Between "#[StartDate]#" And "#[EndDate]#")
Expr1: DLookUp("[Period]","BonusPeriods","(FormatDateTime([ServiceDate]),"yyyy-mm-dd") Between (FormatDateTime([BonusPeriods]![StartDate]),"yyyy-mm-dd") and (FormatDateTime([BonusPeriods]![EndDate],"yyyy-mm-dd"))))
I'm using the following function to calculate date diff in network days (excluding weekends)
Public Function NetWorkdays(dteStart As Date, dteEnd As Date) As Integer
Dim intGrossDays As Integer
Dim dteCurrDate As Date
Dim i As Integer
intGrossDays = DateDiff("d", dteStart, dteEnd)
NetWorkdays = 0
[Code] ....
So when using this function in a query to get number of networkdays between 2 date columns ...it works fine but throws a #Error where there is blank entries in either of 2 date columns...
I need to find a way to display Null instead of #Error...
I have tried this expression but no luck...
IIf(IsError(NetWorkdays([Date1],[Date2])),"",NetWorkdays([Date1],[Date2]))

Hello buddies :D, do you have any idea how to make this work?
To select data that falls within this criteria of date range between cboDate and cboDate2 (fields on my form). The date in [tblJobDetails]![timeIn] come in this format "08/17/06 10:24 AM", but the cboDate/cboDate2 (takes in date only e.g 08/17/06) what i am after is to evaluate specific hard coded time in addition to the date entered, i.e. even tho, i haven't entered time on the cboDate/cboDate2, I want specific time hard coded where e.g If i select a date range of 08/17/06 and 08/18/06 on my cboDate and cboDate2 it should really be evaluating: 08/17/06 8:00 AM to 08/18/06 8:00 AM.
This is the criteria i curentlly have on my query in design view tha works perfect in selecting date only.
([tblJobDetails]![timeIn]>=[Forms]![frmPendingJobs]![cboDate] Or [tblJobDetails]![timeIn]>=[Forms]![frmPendingJobs]![cboDate] Is Null) And ([tblJobDetails]![timeIn]<=[Forms]![frmPendingJobs]![cboDate2] Or [tblJobDetails]![timeIn]<=[Forms]![frmPendingJobs]![cboDate2] Is Null)
How can I incorporate 8:00am to 8:00am into my cboDate and cboDate2. What can i do to make this happen? Your kindness will be greatly appreciated http://www.naijaryders.com/forums/images/smilies/thankyou.gif
Is there a way in a query I can add a Date Diff option to calculate the time between a date that is in the query and now?

I have a database with date and time each stored in a separate field. Now I want to query the database based on a start date/time and an end date/time. I started with the code below but it only returns events within the same time range on each day when what I really need is every event from a specified date and time through a specified date and time.
SELECT myTable.ID AS myTable_ID, myDate, myTime, FirstName, LastName
FROM Staff INNER JOIN myTable ON
Staff.ID = myTable.StaffID
WHERE myTable.myDate >= #3/2/2014#
AND myTable.myDate <= #3/3/2014#
AND myTable.myTime >= #8:00PM#
AND myTable.myTime <= #11:00PM#
ORDER BY myDate desc
In the above example what I want is every event from 3/2/2014 8:00PM until 3/3/2014 11:00PM. But what I get instead is every event between 8:00PM and 11:00PM on 3/2/2014 and every event between 8:00PM and 11:00PM on 3/3/2014.
