Queries :: Function To Calculate Date Diff In Network Days
Aug 7, 2014
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]))

I have written a user defined function that calculates the end of the current month. This I named EndOfThisMonth. It works well as a function. Now I would like to use it as date criteria to include in a query. The function is included as such EndOfThisMonth().
The field on which this function is to enter as a criteria is another calculated date function called Due.
When I run this query I get an error message saying Undefined Function 'EndOfThisMonth' in expression.

Total Days: DateDiff("d",[Date_Open],[Today])
The SQL Details are below. AUNPRDF_AAA802 is a linked table and information gets updated on 12 am everyday
SELECT DateDiff("d",[Date_Open],[Today]) AS [Total Days], AUNPRDF_AAA802.AAAGE AS Age, AUNPRDF_AAA802.AAORD AS [Job Number], AUNPRDF_AAA802.AAWKSP AS Workshop,

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'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])))

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]))

Dear All,
I'm new to VBA coding. A code below is copied from a friend of mine and I can't make it work. How to call up this function in my form. In my form I have 3 text boxes (StartDate, EndDate and NumOfWorkDays). My form is based on a table.
Please anyone who would help me on this, kindly give me the step by step procedure as I am really novice. Thanks in advance.
'*********** Code Start **************
Public Function WorkingDays(StartDate As Date, EndDate As Date) As Integer
On Error GoTo Err_WorkingDays
Dim intCount As Integer
StartDate = StartDate + 1
'If you want to count the day of StartDate as the 1st day
'Comment out the line above
intCount = 0
Do While StartDate <= EndDate
'Make the above < and not <= to not count the EndDate
Select Case WeekDay(StartDate)
Case Is = 1, 7
intCount = intCount
Case Is = 2, 3, 4, 5, 6
intCount = intCount + 1
End Select
StartDate = StartDate + 1
Loop
WorkingDays = intCount
Exit_WorkingDays:
Exit Function
Err_WorkingDays:
Select Case Err
Case Else
MsgBox Err.Description
Resume Exit_WorkingDays
End Select
End Function
'xxxxxxxxxxxxxxxxxxxxxxxx
Can someone please direct me to the right path.

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.

In a query i have setup, i work out when a tenant is next due to pay their rent.
Looks like this
Tenant Last Payment Date Payment Terms Next Payment Date
User1 01/07/13 Monthly 01/08/13
User2 01/07/13 Weekly 07/07/13
The next payment date is calculated using an IF statement and DateAdd in the query, so if it is weekly it adds 7 days, if it is monthly it adds 1 month.
What i am trying to do is write sub query of this one which shows which tenants are due to pay within the next 7 days.
But the access query seems to ignore the criteria I'm putting in....in the next payment date criteria i have tried specifying >Now() + 7 or >Date() +7 but neither seem to work, it just shows up every record...

I have a large database filled with customer records. Some customers come one time. Other customers come 50 times at year. I want to find all customers that have records that are less than 30 days apart so I can ultimately see the types of products they buy. How do I write the query?
I attached a picture of a sample database. The 30 day (+/-) field doesn't exist but I would like the query results to build it.

Ok, so I'm sure this is a pretty simple criteria, but I just can't seem to get the syntax right.
I'm trying to allow my user to select any start date and the query will return that date plus the next three days.

I'm trying to build a query that adds up the total sales for a given product per date. The problem I'm running into is some products have $0 sales on a given day and don't appear in the table I'm querying. How would I get the query to add a record for that day for the given product with 0 in the sales field?
To give more details, I currently have one table showing the sales data. It has a record for every sale that includes the product of the sale, the amount, and the date. In the query, I'm summing the sales for a given day and product. Then I plan to export to Excel where I will run additional analysis.
If there are no sales for the product in a day, I'd like it to list the date and product with a $0 in the sales column.

I'm working on a query ("Target Date of Completion") that takes the initial date started (from Step 1 of date started) and adds the EC (Estimated Completion) which is just shown in days. This will give an EST (Estimated Start time) for the next step in date format, which I would need the new column. Also, As you can see, the piece parts all have a different amount of steps, so this calculation would need to know when it's a different part.

In a database, I have the following date fields that I use to track projects that start and stop.
START1
STOP1
START2
STOP2
START3
STOP3
Is there a way I can use a query to calculate the total days the project was worked on? For example if I enter 1/1/06 in START1, 1/10/06 in STOP1, 2/1/06 in START2 and 2/15/06 in STOP2, 3/1/06 in START3 and 3/30/06 in STOP3, I need to calculate the total days. I need it to work regardless if there are 3 start/stops, 2 or just one start/stop.
I really appreciate the help.

I have a query that has four date variables:
Admit Date
Discharge Date
Report Begin Date
Report End Date
I can calculate the number of days with the DateDiff function when the "Admit Date" and "Dischage Date" are within the range of the report with no problem.
The problem arises when the "Admit Date" is prior to the "Report Begin Date". In this case, the difference needs to be "Report Begin Date" and "Discharge Date".
To make this more complicated, in some cases there is no "Discharge Date", so the calculation needs to look at the first two senerio's and then calculate the days based on the "Report End Date".
Expr2: IIf([Admission Date]<[Beginning of Report],DateDiff("d",[Beginning of Report],[D/C Date / Time]),DateDiff("d",[Admission Date],[D/C Date / Time]))
Expr2: IIf([Admission Date]<[Beginning of Report] And [D/C Date / Time]>[End of Report],DateDiff("d",[Beginning of Report],[D/C Date / Time]),DateDiff("d",[Admission Date],[D/C Date / Time]))
Expr3: IIf(IsNull([D/C Date / Time]) And [Admission Date]<[Beginning of Report],DateDiff("d",[Beginning of Report],[End of Report]),DateDiff("d",[Admission Date],[End of Report]))
expr4: IIf([Admission Date]>[Beginning of Report],DateDiff("d",[Admission Date],[D/C Date / Time],0))
Above are failed attempts to get the formula right.
Can anyone assist me in getting this to work correctly.
Thanks
