Queries :: IIF Statement To Calculate Expiration Dates Within Query
Jun 15, 2015
I'm trying to build a query with an iif statement to calculate expiration dates within a query. For some reason what i'm trying to do is not working as expected.
Here's the situation. Every employees with an exception of two employees in the company has an expiration 2 years after the class took place. The two exceptions are the certified instructors who's training certification is good for three years.
I've created a query with the employeeid, training subject, and maxoftraining date.
I'm trying to write an if statement to give me the expiration date based on the above information. Here's what I have so far; however its not calculating based on the criteria.
Expiration: IIf([tblemployee]![EmpID]=1 Or 2,DateAdd("yyyy",3,[maxoftrainingdate]),DateAdd("yyyy",2,[maxoftrainingdate]))
At this point in time, all "expiration" dates are showing + 3 years rather than just the Employee ID's 1 and 2 and the rest +2 years.

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])))

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've built an an update query that updates a Yes/No field "Expired?" to "Yes" if the expiration date has passed i.e. if the current date is newer than the expiration date. I thought this would translate into the current date being greater than the expiration date?
UPDATE Alert
SET Alert.[Expired?] = 'Yes'
WHERE Alert.Current_Date>Alert.Expiration_Date;
When I run this, it identifies the records to be updated, but then stops updating the fields due to "a conversion failure."

Hi everyone
I'm a very very new access user so many apologies in advance for when I have no idea what I"m talking about.
I'm working on creating a report that will display multiple expiration dates. Currently I have an employee database, not created by me, that has all of our employees professional licenses listed.
Prof license, auto license, liability, etc.
I want to create a report that will tell me what has already expired or will expire in the next 30 days.
I did use this
Between DateAdd("d",-30,Date()) and Date() and it is bringing back info up to 2009. which isn't what I need. I'm sure I'm doing something wrong here.
I want anything that has expired regardless of the date from today, before today, and 30 days from today but I don't care about anything more than 30 days from today's date.
I noticed that when I looked at the existing database that the fields are set as text fields. I tried to change them to dates and it gave me a "deleting 106" records error message. Yikes!
Any help would be appreciated. I don't really understand expressions and I don't understand if I'm supposed to put the actual date in parentheses or what. Please pardon my ignorance.
Many many thanks.

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]))

In my table I have the following 4 fields with the associated date field:
Bronze: 11/1/2013
Silver: 5/1/2014
Gold: 11/1/2014
Platinum: 5/1/2015
I am trying to calculate a value based on comparing the current date to the dates in these fields. I am using the below formula. However, using 6/27/2013 as the current date, my formula keeps resulting in "Bronze" when it should result in "Standard" Am I doing something wrong?
=IIf(Date()<[Bronze],"Standard",IIf((Date()>=[Bronze]) And (Date()<[Silver]),"Bronze",IIf(Date()>=[Silver] And Date()<[Gold],"Silver",IIf(Date()>=[Gold] And Date()<[Platinum],"Gold","Platinum"))))

I am trying to create a database to analyze expiration dates of multiple products.
Let me lay out what I am trying to accomplish.
I have 5 ambulances, each ambulance has the same quantity of medications on it. There are three separate locations medications are stored on each truck. Each month I need to be able to update expiration dates, query what medications will expire by a set date and where exactly they are located.
SO here is the structure as I see it.
Ambulance 1 contains, a drug drawer with approximately 30 different medications, a trauma bag with about 10 different medications, and a blood glucose kit with 2 different medications. Now some of medications are repeated in the different locations, but have different quantities. The medications will never all have the same expiration date, and medication 1 might have 8 vials, where medication 2 may have 4 vials. I would like my form to be dynamic based on the inventory level of the medications. That way if we decide to keep 10 vials instead of 8 the form will then require the 2 extra data points.
The tables I have created so far...
table 1 lists all the ambulances
table 2 lists medications in the drug drawer and the inventory level
table 3 lists medications in the trauma bag and the inventory level
table 4 lists medications in the blood glucose kit and the inventory level
I need to create a table to store my expiration dates for each of the locations in each of the ambulances.
I need to create a form to simplify the entry of the data into those tables and I want the form and table to be dynamic to the inventory level.

My database includes two separate dates related to a vehicle purchase and default payments resulting in repossession. I need to find out how many weeks passed between those dates.
Example:
03/14/12 Date of automobile purchase
06/06/13 Date of last payment before default
How many weeks in between? And then I need to average all of those figures so my company can see the usual week-term time frame that our customers are defaulting and getting repossessed.

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.

For example, an employee absent on 01/01/2015, he will received 2 points, the credit will giving on 04/01/2015, if there is no violation, but if he absent again on 03/31/2015 not only he will received 2 more points his 90 days will start from 03/31/2015, now he will eligible to get credit on 06/29/2015 and so on.So far I have created 3 tables and 1 query.
Tables
Employees: Id, Last Name, First Name
Points: Id, Description Points
Attendance:Id, Date, Employee ID, Points ID
Query

My issue is that I am trying to update a date field. When I do the date field may have a date or may be a null. When I try to pass in a NULL date with no quotes, I get a syntax error. When I have single quotes in the statement and a null value is passed in, I get an invalid use of date.
Dim DENIEDDATE1 As Date
If (Not IsDate(rs.Fields("DENIED_DATE"))) Then
DENIEDDATE1 = Null
Else
DENIEDDATE1 = "'" & rs.Fields("DENIED_DATE") & "'"
End If
update table1 set table1.denieddate = " & denieddate1 & " 'get Update syntax error with this statement
update table1 set table1.denieddate = '" & denieddate1 & "' 'fails due to invalid use of null

I use this
'WHERE ((OperationalRiskEventTable.DateReported)>=Forms!U pdateForm!UDateBegin And (OperationalRiskEventTable.DateReported)<=Forms!Up dateForm!UDateEnd)'
in a query by form.
The problem is that you have to enter a date in the between values for results to show. If I don't enter information into a different field such as Full Name but I enter in 40 into Age then everyone that is 40 years old will show. On the other hand if I enter 40 into the Age field but I leave the Date Reported fields empty then no results will show.
How can I change it so that I don't have to enter dates into the date reported fields for results to show?

I am creating a multi-search form for a student database, where after I enter my search criteria I hit a "Run Query" command button and then it opens a query form with all of my criteria.So far I can search using last name, first name, and middle name. When I try to search with a start date and end date I am have issues.The start date and end date is for the class date. In the query form under the field, class date, for criteria I wrote:
Between IIf([Forms]![Search Form]![Start Date]="",1/1/10,[Forms]![Search Form]![Start Date]) And IIf([Forms]![Search Form]![End Date]="",4/25/15,[Forms]![Search Form]![End Date])
I want it when I write a date in the start date and end date I want it to give me a list of all the students who took the course between those dates. Also, if I leave the dates blank I want it to search all dates. The dates 1/1/10 and 4/25/15 are just the dates I gave because that is far back as my database goes.

How to calculate the percentage of kilometers per order compared to the total number of kilometers per carrier.
In the attached screenshot send queries where I need formula.
Mileage on the orders of the field called "Korkma" . The formula should look like: # [Korkm] / [total kilometers per carrier] #.
I do not know how to get the total mileage driven by the carrier (the carrier is in the query in the Field Name Plate) for the month.
For example:
date 1.1.2013.,Plate:Pribus Korkm= 37
date 2.1.2013.,Plate: Pribus,Korkm=56
date 10.1.2013.,Plate: Pribus, Korkm= 70
Formula: [37]/[163] = 0,23
[56]/[163]= 0,34
[70]/[163]= 0,43

Is there a way to calculate the mode value in a query?
In a summary query, I need to return the value that shows up the greatest number of times in a certain column of a table. Is there a function built in to Access or an easy way to perform this, or do I have to make my own function to handle this?

I have a database that I need to calculate a query that is based on 3 dates. For example...I have an admission date and a discharge date in my database.
If there is no date in the discharge date then I need it to calculate the number of days between the admission date and "today's date." If there is a discharge date then I need to calculate the difference between admission date and discharge date.
Basically i need a length of stay figure. I can figure the formula in excel but cannot get it to work in access. Here is my formula in excel
=If(ISBLANK(DischargeDate),Sum(today()),sum(Discha rgeDate-AdmissionDate)

I have two excel tables that I linked in access. From excel tables I created query that gives me all data I need.
First table has data of periods and prices of apartment per period. For example:
PropertyID 1111
PropertyName Apartment Zagreb Mila
StaringDateOfPeriod 1.1.2015
EndingDateOfPeriod 1.7.2015
PriceForPeriod 100
.
.
PropertyID 1111
PropertyName Apartment Zagreb Mila
StaringDateOfPeriod 1.7.2015
EndingDateOfPeriod 31.12.2015
PriceForPeriod 120
Now as you can see I have apartments with prices that change per periods.
Second excel table gives me information of total paid service that customers need to pay , number of days that he will stay and CheckIn and CheckOut dates of those guest.
In calclutated fields in query I created calculations like TotalyPiad(from 2. table) - OwnerPrice*TotalyNumberofDays . I guest good result IF i have reservations that matches or is it BETWEEN StartDate and EndDate of periods.
BUT If I have reservation that is overlapping , where CheckOut of guest is 1 or more days > that EndDate of selected period I have problem with calculation because my calculation is based on WRONG price in that period.
For now what I manage to do is to create separate field in query where I calculated number of days that are out of range
CHECK_IN - StartingDate of period
CHECK_OUT -EndingDate of period
Check-in date - starting date of reservation of guest
Check-out date - ending date of guests reservation
nabavna cijena - owner price
Code:
PreklapanjePerioda: IIf([Check-out date]>[CHECK_OUT];[Check-out date]-[CHECK_OUT];Null)*[nabavna cijena]
But still when I calculate those number of days I multiple those number of days with old period.
So How can I MULTIPLE THOSE NUMBER OF DAYS WITH PERIOD +1 , I meen next period not this old one just for those days that are out of range? [CHECK_OUT] +1 doesn't work it just add extra day in my CHECK_OUT filed
My final idea is :
Separately calculate in one field number of days that are out site of range
Calculate number of days of reservation of guest that are in range
= make sum of those two fields
From that I will create report which I will send to our owners of properties (number of reservations, reservations details, price that they need to pay to us ...)
I also thought this could be possible to make using VBA but I am still not skilled anough in it. Also I was thinking of creating calendar where I would that add those two queries but how to create simple calendar in Access. Is there some template for simple calendar in Access?

Utilizing access 2010, I have used the left, mid, and right command to separate hour, minute, and second into their are separate table values 7 05 35. The AS400 database stores 3:15:30pm in the following manner 151530.
At this point, I used the string function and created the following table value 7:05:35.
Overall, I am needing to convert 70535 to time and then calculate lapse time where the employee name is the same. my database has about 2500 unique employee records per day. I am utilizing a query to perform the above.
