I am using Access 2013.I am trying to create a query that will count the days difference between two dates. The dates are in the same field. I want to group by Region.So:
tblRegion = RegionID
tblStatus = StatusDate
I know how to use the DateDiff when it is two different fields, but I can't figure out how to do it from the same field.
How can I calculate the difference between two dates but I only want to count the work days? So if was today and I wanted to go until 6/15/2015 the difference would be 5 and not 7 because I do not want to count Saturday or Sunday. Is there a special %datediff function where I would only count work days?

I have a problem in calculating the difference between two dates and displaying the output into Years Months Weeks Days. My problem is that dividing the number of days by 30 and requesting an integer is not accurate enough. I have looked at Pat and Jons examples shown in these threads
http://www.access-programmers.co.uk/forums/showthread.php?t=67472
http://www.access-programmers.co.uk/forums/showthread.php?t=89051&highlight=calculating+number+months
which either method would suit me as the accurate answer is what I am after.
My problem is that not all of my records would have a start and end date. Therefore both examples would result in an error.
Can anyone please give a hint on how to perform the calculations on those fields which have dates recording the results but ignoring those fileds which do not have a start / end date.
I am having a bad day and I'm sure the answer is so easy that I am going to kick myself but having played around with the modules by limited knowledge is not enough.
Many 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 have a form called subfrm_vactions
rowsource is a query called qryVacations
the query should calculated two things
1 - the difference between start_vac and End_vac in days to calculate the vacation period and put the value in field called Period (working well)
2-the work days which the period between the last day in Previous record (End_Vac) and the (Start_Vac) in the next record (didn't work)
the result is the difference between (End_Vac) and (Start_Vac) in the same record which i don't want
simply i want to calculate the work days.
I have a form where a start date is inputted (Inputfrm , StartDate) and a form where the end date of the process is recorded (Inspectionfrm , EndDate) and these both record in the table InputTbl as StartDate and EndDate respectively.
I have created a union query which shows a list of all the dates where there is work recorded (WorkingDatesQry and the column of list of unique dates is "WorkingDate"), and as we run a highly varied schedule depending on time of the year and order numbers I cannot just use a query which says Monday-Friday or Tuesday - Saturday.What I am trying to do is to find the number of days between StartDate and EndDate where there is a date recorded in the WorkingDates query.
I've had it before, but can't find it.
basically something like this --
DateDiff("w", StartingDate, EndingDate)
that also makes sure date is not in tblHolidays.
anyone knows how to acomplish this ?
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]))
I have the attached database which calculate the Difference between dates.I have also two problems like i shown in the image
Code:
Option Compare Database
Option Explicit
Sub Recalculate()
Dim rst As DAO.Recordset
Dim dff As Long
[code]...
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.

View 14 Replies View RelatedI 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.
View 3 Replies View Related I am wanting to get an expression that will return the difference in years and months between 2 dates. Specifically, I want to know peoples ages in years and months based on a person's D.O.B and todays date. I have managed to do it in years:
Expr1: DateDiff("yyyy",[TBL_EmployeeDetails]![D_O_B],Date())
and in months but I would like to know how to return the difference in years and months.
My database keeps track of training for employees, some of which expires after a period of time, which is in the tables. I need to create a query that displays only the employees and the training that expires during the next 30 days. I have a query that displays the expiration date (this field uses DateAdd and adds the expiration term to the date the employee completed the training) I am trying to add a criteria to this field. I found <=Date()+30 in my searches but that displays all of the records from 12/14 and back. I have tried all kinds of versions of this (obviously, not the correct one) and either get all records or none. (Yes there are records in the database that fall within the the period I am trying to display - that is something that I have been known to forget)
Is it because I am using criteria in a field that is based on DateAdd or what would be the correct criteria for this?
I have 2 dates that I need to count between. Easy enough just use the datediff right? Nope cause it won't count just the 5 workdays. I researched and found that the "w" in the function doesn't work the way I need it to. I found lots of code to make a module that will do it for me and they all include having a holiday table. Right now I don't need a holiday table I just want the simple dates in between.
View 2 Replies View RelatedI have a query that records a status update, and the date it was made by an employee etc. The table has a secondary key related to ... lets say a project table.
E.g.
Status Id; EmployeeID;ProjectsID;Status;Date
I want to calculate the average amount of days it takes for a status change occur.
I'm trying to calculate the number of days between two dates using the iif statement
Fields:
[LDW] "Last Day Worked"
[ReturnedDate]
DESCRIPTION: If ReturnedDate is null, then calculate the datediff "d" between LDW with Now(), if not, then calculate the datediff "d" between LDW with ReturnDate.
I tried this but it didn't work at all.
Days Absent: Iif(isnull([ReturnedDate],(DateDiff("d",[LDW],Now())),(DateDiff("d",[LDW],[ReturnedDate])))
I have two tables with dates. Between (!) every two following dates in table1, I want to know the number of dates in table2. How do I write an SQL query for this? The tables I have are up to a few hundred records in table 1 and a few thousand records in table2. So to prevent that this takes hours I need a fast query.
To explain the query I need, for example:
table1
01/01/2014
15/01/2014
17/01/2014
30/01/2014
table2
01/01/2014
02/01/2014
05/01/2014
17/01/2014
18/01/2014
20/01/2014
21/01/2014
25/01/2014
So the answer of the query would be 2,0,4.
Explanation:
Between 01/01/2014 and 15/01/2014 in table 1 there are 2 dates in table2 (01/01/2014 is not included between the dates)
Between 15/01/2014 and 17/01/2014 in table 1 there are 0 dates in table 2
Between 17/01/2014 and 30/01/2014 in table 1 there are 4 dates in table 2
I have to count the number of days each week (7 days) that a person has worked - simple enough.
But - what if they come off the job within the week?
I have been using the DateDiff function which is fine.
In the database they have a Mobdate and a DeMobDate but if the DeMobDate falls within the week the whole thing falls apart?
I got an assignment from my supervisor and I am not getting it! :(
I have a query (see result in attachment) with the following fields:
tID, emailID, emailtype and EmailDate.
Example:
A customer (tID 1297542) sends an e-mail (emailtype 1) to the company on 2-8-2005.
The company replies on that e-mail (emailtype 3) on 5-8-2005.
Problem:
I would like to create a query that shows per tID the total of days between the e-mail from the customer and the e-mail from the company (between emailtype 1 and 3).
I want the number of days between a specific date (roll out date) and 12/31/2005 so that
I can use the number to project revenue for this year.
This is what I'm using but it doesn't give me the right number. I don't know how to transform
something to a datetime variable so maybe that's the reason. Can you help me out?
Expr4: Day(12/31/2005-[Scheduled Roll Out Date]-0.49999)
Hello,
I have two fields in a table, both containing dates. I would like to write a query that returns the difference between the dates in an year, month, day format (i.e. 26y 2m 3d). If that isnt possible, can the difference be returned as years,days (i.e. 26y 63d).
Thankyou.
I just can't seem to get this one to work right. I've got the following query. I need to count the number of Null dates or show zero if there are no Null Dates.
Code:
SELECT DISTINCTROW qryNoticeResponseNew.fldNoticeID, Count(qryNoticeResponseNew.[fldResponseSeen]) AS fldCount
FROM qryNoticeResponseNew
GROUP BY qryNoticeResponseNew.fldNoticeID;
Which is just counting the number of dates so far. It got me to thinking I need to do something like this.
Code:
SELECT DISTINCTROW qryNoticeResponseNew.fldNoticeID, IIf(IsNull(qryNoticeResponseNew.[fldResponseSeen]),1,0) AS fldCount
FROM qryNoticeResponseNew
GROUP BY qryNoticeResponseNew.fldNoticeID;
Which pops a "cannot have aggregate function in expression" error.
I want to do a unique count of dates when an activity was done in my table. The table may have multiple entries of the activity performed possibly on the same date by an individual
e.g. table entries
Code:
approvalNoSys dateAssessed Activity
100 01/08/2015 Audit
100 01/08/2015 Audit
100 01/05/2015 Audit
100 01/05/2015 Audit
100 01/02/2015 Audit
100 01/01/2015 Audit
Unique audit Count must equal 4
Code:
totV = ECount("[dateAssessed]", "R_P_Data_P", "[approvalNoSys] = '" & [Forms]![cmrOverview]![txtappNoSys] & "' AND [Activity] Like '*audit*'")
totV = Unique count
dateAssessed = date field in R_P_Data_P table
R_P_Data_P = table
"[approvalNoSys] = '" & [Forms]![cmrOverview]![txtappNoSys] & "' = criteria for the customer in question to separate them from many other customers in the table.
Activity = text field in R_P_Data_P table
audit = the activity
I'm also trying to avoid having to build total queries etc to them reference them, I'd like getting the desired outcome in an expression or small code.
I read about Ecount but my complier doesn't recognise the function
I have 2 linked tables, tblPN & tblReceivedDate. tblPN has field PN and tblReceivedDate has field [Received Date]. The tables are used to record the receipt of different part numbers and the date they received. I want to use a query to count how many times a part number is received. The catch is that I only want to count a part once even if it is received more than once on the same date. With the data in the attached DB the count for PN 123 would be 5.how to configure the query to do what I need to do?
View 9 Replies View RelatedHello,
I think this might be a typical question for query builders, so I apologize in advance for asking something so basic.
I have a form with two controls (start_date) and (finish_date).
Is there a way that I can create a query that will count the number of times a "source" has been entered into a table?
For example, I have a database where potential customers call and ask about our services. We ask them "Where did you hear about us?", hence the "source" field (which is a drop down combo box to normalize that field's data).
With this record is their "dateofcall" which is (obviously) a date field.
I'd like to create a report that will count the number of times a "source" has been entered between two dates "dateofcall" (the start and finish date above).
I have tried many types of queries and haven't found any success. The nice thing about the two form controls is that I can use those two controls for a variety of all types of queried reports. (the user enters a start and a finish date, fires a command button that generates a given report between those two dates). And it works well!
Can anyone help? I'd be most appreciative!
Mike
