Queries :: Calculate Difference Between Two Date Fields To Get Total Time
Oct 26, 2014
I have to create a query in access that will calculate two Date and time fields [Date & Time Left]/ [Date Returned], need to figure out between the two fields. Trying to identify when the rep returned the call and the number of business hours (6:00am - 4:30pm) it takes to return a message in Ms Access 2010.
The only issue is the calculation has to be done by time and so I have to calculate what time they left the message(so the difference between [Date & Time Left] and [Date Returned) [Date & Time Left] and when the rep returned the message which is suppose to be [Date Returned] but the problem with this field is the data entry is in date format (10/9/2014, 00/00/0000) of Date and not Date and Time like the [Date & Time Left] field, so I don't know what to do now. Not sure what to do now not a database that create or have allot of control over.
ID Up Time Down Time John 18:00 15:00 Kelvin 08:00 08:05 Melisa 23:00 02:00
This is the Table , i need the Query result show IF [Up Time]-[Down Time] is >=3 hrs
Like Below :
ID Up Time Down Time John 18:00 15:00 Melisa 23:00 02:00
IDUp TimeDown TimeJohn18:0015:00Melisa23:0002:00
I tried DateDiff("h",[Up Time],[Down Time]) in Field but POP out with error "Syntax error (comma) in query expression 'Table1.[DateDiff("h",[Up Time],[Down Time])]' " ...
I am trying to calculate the difference in dates between two fields. How do I find the difference in days between field one which contains the date 04/12/2011 and field two which contains the date 04/12/2013? I have tried to use the datediff function, but it keeps telling me it doesn't recognize the field name, even though the spellings correct.
I,ve made the following date fields in a form: begintime, endtime. I've also made a field Diff that calculates the difference between the two by the code : Diff = Format([begintime] - 1 - ([endtime], "Short Time"). Bij this code you can calculate the difference even over night.
But now I've got to calculate the part of the time someone worked between midnight and 06:00AM if that person indeed worked in those hours.
e.g. someone started at 16:00 end ended at 03:30. The part of time I need = 3:30 e.g. someone started at 01:00 end ended at 11:00. The part of time I need = 5
How can I accomplish this? I hope someone can help me because I'm :confused:

Code: SELECT [Message Tracking_tbl].[Date & Time Left], [Message Tracking_tbl].[Date Returned], [Message Tracking_tbl].ID FROM [Message Tracking_tbl];
I'm trying to calculate the difference between start and end time, which works fine with:
Total Time: DateDiff("n",[tblTaskTimes]![StartTime],[tblTaskTimes]![EndTime])
However, this is for a database that calculates billable time in 10th of an hour. So, for example, 1 hours would be 1, 30 minutes would be .5, less than 6 minutes would be .1.
The format for this expression is set up to a general number, if that matters.
It's gotta be something in the formula like multiplying this by 24 (for 24 hours) and then dividing by something. Nothing I'm trying is working.
I have a subform in which I want to calculate the difference between a start time and finish time, the problem I am having is when the start time is on a different date to the finish time
Start 23:15 on 14th Jan finish 00:015 on 15th Jan, also I want the answer to be the number of minutes. The fields I have are
BatchStartTime Short Time BatchFinishTime Short Time BoilTime ([BatchStartTime] - [BatchFinishTime]) General Number.
There are many batches to enter per job and the MainForm has the StartDate as I didn't want to enter the StartDate for each batch.
Any way of setting up a table containing the following date/time fields.
StartDate StartTime EndDate EndTime
Ultimately I will need to be able to subtract these date/times to get a total time between the two. Should I combine the start date and times in one cell or keep them separate.
In either scenerio, how do I subtract the two in a query for a report?
I am trying to create a query that has a self referencing running total based on the values (point totals) of itself (running total of values in the running total column that have already been calculated for all previous records) plus the total of new points being added in the current record, less the total of points being removed in the current record. This running total can never go below 0, if it does, the running total should restart at zero and add in only new points and begin the process again with the next records
I am able to do this in Excel in less than two seconds so I know there has to be a way to port this into a query. I've attached an excel example of what I am exactly trying to do
If it takes multiple queries to complete the required output I am ok with it. In my previous outtakes I have had up to 8 queries but just couldn't seem to do it..
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.
How to implement a functionality into my access database. The related tables required for this functionality can be found as an attachment.
When the information has been entered into the tables by the user, I would like to calculate the difference between the information for each part within the same table. The main columns for which the difference have to be calculated are: [RefObsInfo->RefSources] and [AltObsInfo->StatusAltSource] and [GenObsInfo->GenSources]. The values for these fields are restricted to 3 or 4 different ones. I also would like to show if the GenEstAvailable columns are changed, but that's for later.
In order to calculate this difference a query has to select for each Part the information related to the last date AND a date which has been specified by the user (with the previous date as max). For this the user is asked to give a from date, which she/he can select from a combobox. This combobox has a standard selected value which is the MaxDate-1, i.e. the previous date. The difference should be calculated from the previous date to the last date. I would prefer to give each (predefined) difference a specific action to show the user the difference in a matter of seconds.
I have a table, tblDailyCalls, that contains agent_name, date, calls_ answered, and talk_time. Ideally on a form, the user will select an agent, enter the date range in txtStartDate and txtEndDate and a report opens to show what the total amount of calls and talk time is for that date range.
All I've managed so far is doing a simple expression on the report itself to sum the fields I want. But my method returns every date in the range. I would like to only display the total.
I've been trying with Totals in the query and crosstab queries but am not familiar with them.
Hi All. I try to generate a report which calculate subtotal for patient AMOUNT for current year and total for whole period from first visit to current date. The result of subtotal =Sum(IIf(Year(Date()=[VisitYr]),[Amount])) is the same like total. What is a correct way? Thanks.
I'm trying to find the difference between 2 dates [Start_Date] and [End_Date], however I want to strip out out of hours work, which is [OOH_START] eg, 17:30 and [OOH_END], eg, 08:00. Also I need to strip out the weekends as well.
I need to calculate (in a query) the Actual Time of a job. I have the start date, start time, end date & end time (all separate fields). This seems to works ok by subtracting the start from the end.
Then I need to calculate the Estimated Time (time it should have taken). This is done by taking the Quantiy divided by the Rate-Per-Hour. This seems to work out ok in the Query, e.g., 101000 / 15000 = 6.66667 hours. But when I display this result in a report as a "Short Time", I get 16:00 instead of 6:40. How can I get the correct display? The other problem is that I need to divide the Estimated Time by the Actual Time. This also gives me wierd results - I suppose because one is a decimal format time and the other is a "Short Time" format. How can I get the correct answer?
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
Income | Outcome | Transport | Total Income | Date Total Income (N) = Income (N) + Transport (N-1) Total income equals income from that day + transport from previous day
Transport (N) = Total Income (N) - Outcome (N) Transport from previous day equals Total Income minus outcome
How can I calculate the transport from previous day to sum to next day total income?
I am having trouble with this running total. Let's say I have a well. I am trying to create a running total that calculates the total Uptime (or hours operational) for each well every month.
I attached a PDF with an example of what I am working with.
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.
Basically I have a report that shows any 'Issues' that wasnt closed within the KPI Target.
I have the report working, but I simply want to do a count of how many days the observations overran the 'Target Date of Closure'.
The report also shows observations that are not closed but passed their Target Date of Closure. These observations will not have a 'Actual Closure Date', but I would like to still have a count of how many days its overrun closure.
This is a formula I tried to piece together but obviously not correct as it's not returning anything;
IIf(IsNull([Issues]![Actual Closure Date]),DateDiff("d",[Issues]![Target Date of Closure], Date()),DateDiff("d",[Issues]![Target Date of Closure],[Issues]![Actual Closure Date]))
