How To Calculate Half Day
Jan 11, 2015
On this db, the users input a FROM date and a TO date to apply for leave, and the number of days required is calculated. I was able to get this done, but the problem is if they want leave for only half a day. The term that we usually use is FN and AN. What I want is this: If they choose FN to FN, or AN to AN, we should get .5. If they select FN to AN or AN to FN that is one day. Saturdays, Sundays and certain other days are holidays. On Table2 I have a FROM field and a TO field, but no field for AN/FN (yet). How can we accomplish this?

I have an access database used for recording training events. I was able to calculate the number of days each training event took by using
Datediff("d",[Training Date From],[Training Date To]+1)
I was really chuffed with this until my boss asked what happens when the training only lasts half a day! I added the time to the above fields to make them date/time fields but can't see a way to calculate in half days.
As well as this the other problem is that training could be over a few days. As an example I'd like to be able to input that the training started at 9am on Monday 29th May and ended at 12 noon on Thursday 1st June and get the result of 3.5 days. The full days would all end at 5pm but I wouldn't be recording that, just the total days. I tried changing the datediff function to hours in the hope I could somehow discount the non working hours but that didn't work! I'd ideally like the final result to be in days, ie 0.5, 1 etc. It would always be in whole or half day increments - don't need things to be overly complicated!
Any help will be very gratefully received. I'm definitely not an expert as you can probably tell!! :eek:

Can anyone help with this ANNOYING problem?!
The Database Window within Access on my computer seems to have kinda half disappeared under all the toobars at the top of the screen. Each time i open it it seems to have moved further up. The problem is, that because it is underneath the toolbars, I can't click on the window of it to drag it back down! Now, its got so far up that i can't even select any of my tables, forms, queries or reports because i can't see them!
Its SOOO annoying! and i have no idea what to do about it!
Help please.....:confused:

Hi could someone point me in the right direction for this one,
I have a series of linked tabbed Forms. One of the Forms is mostly populated by Combo boxes which all work fine. My problem occurs when you go to add a new record and populate the form with the combo boxes but decide for some reason not to save the record but exit the form using the Close form command button or by using the close button at the top of the Form. Access seems to Save the record anyway. I have placed an Undo Cmd on the form to clear all text boxes which works fine but it does not stop a user from closing or exiting a Form by another means and stop them saving that incomplete record.
I would be grateful for any thoughts on how to solve this problem.
Thanks in advance

I am trying to round off times to the nearest half hour. To be clear, I don't want to only round down or only round up. I need the rounding to be to the nearest half hour. I want to do this in the query, not vba. I've attached a picture of the query.

Hello,
I am trying to sum minutes from a database using an Access query, but the format in the database is hh:mm. I know the query to use in Oracle:
ROUND(SUM((substr(actual_time,1,(instr(actual_time ,':' )-1))) *60 + (substr(actual_time,(instr(actual_time,':' )+1),2)))
but not sure of the syntax to use in an Access expression.
Any ideas?:confused:

HI,
Excel is having difficulties calculating a workbook of mine. It complains about cirkular references, so I had to set the iterations manually.
The workbook holds about 5000 records and I´m using a cosinus function.
The thing is I don´t know what to do. Excel calculates the workbook, but it doesn´t do it right. What setting should I use with the iterations?
I´m thinking of running it in excel 97. Will that help?
I really need to be able to run this workbook. Does anyone have an idea?
Fuga.

Hello, I didn’t know how to explain this or where to post this but here we go! I have two databases and one of the PC's here at work can’t use some of the items in the database like on one of the databases there is some formulas in text boxes and that PC won’t calculate what’s needed in them and every PC in the plant will except for this one PC. Also the one PC won’t bring up the Allen Browne's Calendar. When you press the start or end button to bring up the calendar it never pops up but if I enter the start date and end dates and use it that way ect then it works. I have no clue why this is just happening to this one PC. Any ideas?

i have a table with fields "[DATE OF BIRTH]", "age", "temp-age"
i have a query that calculate the age:
example; the query will get user to input the "temp-age" and upon "temp-age" is input and "ok" on the query, it will calculate a person's age and store the value inside table "age".
however, the calculated value for the age have some data problem. for example, when a person whose age is yy:mm 24:05 the age inside the table will be 1924:05. there will be a additional "19" at the age.
what cause the additional "19" problem?
---------------------------------------------------------------------
my query in design view is like this; (see attachment)
it uses " [temp-AGE]-[DATE OF BIRTH] " to calculate the age and store into table "age".

Hi
I am very new to databases, and think i am a bit over my head. I am doing a database for vacation rentals, and am trying to calculate commissions, basically i wanted to have a set of checkboxes, labeled 10%, 15%, 2.5% and $25, with any combination of these checkboxes being able to be checked.
i want the query to work like this:
If the 10% checkbox is checked i want the query to take the SubTotal for the reservation, and calculate 10% of that number. if the 2.5% checkbox is also checked, i want the query to calculate 2,5% of the reservation and add it to the commissions total (10% + 15%)
I think(hope) that i explained that clearly? Can this be done?
Thanks for your help!

In a report, I need to calculate the percentage of clients that respond "Yes" to a question on a survey. I need to create a query that will return the count of the number of "Yes" responses, and the number of total responses.
For example, if 10 clients complete the survey, and seven respond "Yes", I need the 2 fields in the query to be 7 and 10. So far, I have only been able to do this using multiple queries.
Thank you.

Any suggestions?

Hi,
I have a from with 3 fields on it where users can enter numbers of boxes attached to a booking.
Each field stands for a box of a certain type.
E.g.:
20's ==> 1
40's ==> 1
45's ==> 1
Now, I want to calculate a total based on 40 being 1, 20 being 0,5 and 45 being 1,125.
The total in this case would be:
2*20 = 0.5
1*40 = 1
1*45 = 1.125
Total: 2.625
Is this possible, and, if yes, how do I insert this calculation?
Don't know if this is clear enough, if someone has any questions on my goal here, please ask me to clarify...
Thx once more,
Lion85heart

I am relatively new to Access, and wasn't sure if this is query-related or not. I am trying to set up a database in Access 2013 for vehicle maintenance and fuel tracking. I have a table called "fuel" where I enter fuel purchases (including mileage at fillup, total cost, total gallons, etc.)
I want to have a field in this table called "MPG". This field, for a given row, will take the number from the "mileage" field and find the total miles traveled by looking back through the previous rows and finding the next highest mileage. It will then divide this difference by the number entered in the "gallons" field for the current row, and this will give the number for the "MPG" field.
I'm sure I'm making this sound way more complicated than it is - I'm pretty sure everyone knows how to do an MPG calculation - and I could do it with Excel by just using VLOOKUP or INDEX/MATCH (or even just by assuming that all fuel entries are chronological and looking back at the previous row). Just not sure how to accomplish this in Access!
