DateDiff In A Query

Jul 26, 2006

Have a table which has 4 fields PatientID FirstName,LastName,BalanceDue,Due Date
Trying to create a query that will show all fields of the accounts that have due dates that are under 30 days. I tried this Under30: DateDiff("d",[DueDate].Now())criteria >0 And <30. But can't put anything in the parameter dialog box which after clicking ok shows any data. If I can get this to work my hope is to have 3 more catagories. over 30 days, over 60 days and over 90 days. I'm new at access and could really use some help.

DateDiff

Jun 16, 2006

Is there a way in a query to write a datediff that looks at all the possibilities month, day, year? I have 10 different fields that I need to do a date diff on. I would like to have the fields checked in one place rather than 10 day checks then 10 month checks and 10 year checks. I don't need to use the data any where but I need it to let me know if there is a difference between a calculated date and a date that was input by a user. If there is then I know the user input the wrong date, and it shows as an error.

Thanks

Need Help With Datediff

May 14, 2007

Hi,
I am trying to calculate the number of days between 'today' and a 'date of birth' field. In the field properties Default Value I am using =(DateDiff('y',Date(),[dob]) where Date() gives today's date and [dob] is my 'date of birth' field. However, this is not working. I get an error "(The database engine does not recognize either the field 'dob' in a validation expression, or the default value in the table 'Table1')"

I have set the data type for both fields to 'Date/Time'. What am I doing wrong? Is there any alternate method?

Also, how can I calculate height in feet & inches (5'6" or 5.6 or 5-6) from a given height in meters?

Thanks
Raj

Datediff???

Oct 3, 2007

hello all,
would really appreciate some extra help with this,
many thanks,, the story is as follows,,,,,,,

hello all,
i have a very simple databse with two table in it,, both table share a lot of common information, including a primary key called jobcard number,, i want to know if there is a simple query i can run that will find any differences in the start date fields that are found in both tables
any help would be much appreciated
cheers
wardy
---------------------------------------------------------------------
Look at DateDiff function in the help for the time differences.

Thus for example in a new column in your query you can type:
DifferenceInDays: DateDiff("d",[Table 1 Name].[DateField Name], [Table 2 Name].[DateField Name])
--------------------------------------------------------------------
thank you DrSnuggles,
could you explain in idiot proof instructions?
do i enter the diffdate code in the criteria row of the select query? also, what do i need in the field and table rows? is it the table and filed i'm comparing the data against?
once again
many thanks

Datediff() Help

Apr 9, 2008

I have a call tracker database.

What I'm trying to create a query to view all my calls' time average (opened date and resolved date). Basically, how long it took to fix a call or problem... whatever...

I tried with datediff(), but had problems getting the Total Avg.

I would need the query to look like this...

Total Calls | Avg Call Time
100 | 5.33 (min.sec)

Thank you

What Am I Doing Wrong??-Datediff

Aug 30, 2005

I am trying to calculate the total number of days between a date (i.e, csdate) and todays date in a Query for a Report.
I have tried the DateDiff command in the query line and in an unbound box on the report but it is not returning the right values.
Can Someone tell me what I have done wrong. I have checked that the date is in long format and tried it in short format as well with the same results. Below is what I have tried.
csdays:=DateDiff("d", [csdate], Date()) I have tried the Now() command as well, but it is not right either.
Please help!

DateDiff Error

Mar 21, 2006

My company recently switch us from Access 2000 to Access 2003. A query that previously worked, no longer works. I've searched the previous posts and Access help and updated the query based on the search results, but still receive the error message. "Undefined function 'Date' in expression."

Here's the query calculation:

AppOut: DateDiff("d",[AppMailed],Date())

Would someone please let me know where I am going wrong?

I've gotten it to work with this calcualtion, but the user has to manually enter today's date each time. But I know there has got to be an easier route.
AppOut: DateDiff("d",[AppMailed],[date])

Thanks =)

Pretty new to all this, so forgive my ignorance but i'm having problems with DateDiff. I have a table with 2 dates in it, and I want to work out how many working days (or working hours if possible) are between the 2 dates

SELECT DateDiff("d",[Date Opened]+[Date Closed])
FROM Dashboard;

I want it to print it the number of working days/ hours in a new column in the Dashboard table if possible.

Any ideas?

DateDiff Function

Jan 18, 2008

Hello,
I am trying to create a query that subtracts "TimeOUT" from "TimeIN" fields to calculate the total time worked.

The "TotalTime" is a new field that is not in the table, only in the query.

I am attempting to use the DateDiff function to calculate this, but I need to return both hours and minutes.

Currently, it looks like this:
Total Time: DateDiff("h",[Time IN],[Time OUT])

It works this way to return the total time in hours only.

The DateDiff function works to return either hours (h) or minutes (n) but I cannot figure out how to get both!

Perhaps someone has an answer or possibly a better way to get the results in hour:minute format for me??!!

DateDiff Fractional Months

Aug 28, 2006

I need to (accurately) calculate a rental period to fractions of a month.
ie) 1/1/2006 to 2/14/2006 would equal 1.5 months.
DateDiff("m",[Start],[End]) returns whole months.
DateDiff("d",[Start],[End])/30 is very close , but not precise.

Is there a way to accurately calculate fractions of a month?

Thanks,

Sup
