How To Calculate Date Cells That Are Empty
May 6, 2014
I have a query that has 11 dates on it, I am trying with iif statements to get it down to one column reflecting the most recent date out of the 11, for example 5/2/14 and 4/9/14, I would want to have 5/2/14. The problem with this is that most of the cells are empty and and I can't calculate empty date cells. my thought was to create a statement that goes something like this iif([Date1]="", "1", [date1]), obviously this does not work but I would like for it to show something other then nothing so that I can calculate on it.

I have a Query pulling data from several tables. If there are empty cell with no data in them, they cause the Query to completely skip that record. It does not show up in the Query. Not practical since most of the data int the table will not be entered until some time later.
What gives? Is there a way around this?
Thanks.

I have added a delete button to my form but now I cannot save the form.
I get the error message:
"In order to save your changes you must remove any layouts that have empty cells in them and/or set the has module property for the form to no."
How do I locate empty cells.

I have a variable cost that is a calculated field (as in the colum only exists in a query not as a colum in a table) that is variable hours * variable rate....the problem is ppl at my company sometimes dont know how the costs are goign to be broken down so they only put a Variable Cost....
and since they dont know the rate and hours my calculated field returns nothing...
how can i accomplish this, VBA might seem the way to go but i don't know how to use it for Access.....
so basically i need to calcualte the variable cost only if they enter something in var hours and var rate...other wise the var cost should just be what the users type ( so i i guess i have to make Var Costs a column in the table to give users the option of entering it)

Sorry the title dosen't make much sense, can't come up with a good title. Here's the problem, I work in a hospital and I have a program that store patient's admit date and discharge date. My concern is, I need to calcuate patient days (the amount of days the patient stay in the hospital). Let's say a patient was admitted on Jan 15th and discharged on March 20th. So I need to build a query that capture the months, let's say I do it on Feb, how can I tell that this patient was here on Feb? since I have admit date and discharge date. Thanks
eg. we have 4 patients John Smith, Ortiz Prerez, Jim Johnson and Nancy Cruz and we are running the query for Feb.
ID Name AdmitDate Discharge Date "The result should be"
1 John Smith 1/2/07 1/26/07 24 patient days
2 Ortiz Perez 1/27/07 3/4/07 28 patient days (because this user was in the unit)
3 Jim Johnson 12/25/06 Null 28 patient days because of Feb month
4 Nancy Cruz 2/14/07 4/1/07 14 patient days

I have a database which stores information relating to club members, which I'm in the middle of giving a bit of a facelift and one thing I want to automate is the calculation of the expiry date.
My memberships expire annually at the end of December and the expiry date is set as a default value within the table properties. This has to be manually changed every September (every new member from then pays for 15 months) to the following December.
Is there a formula I can insert in the defaul value field that will return December the current year if todays date is between January and August, and December next year if todays date is between September and December?

I am creating a query with criteria for a dates column. The column cotaining dates in my Table has many empty fields. I want to limit the criteria for my dates to >#1/1/2004#, but I don't want Access to exclude all the empty fields because I want all the data displayed for the purposes of my report.
What do I do? I'm not terribly familiar with Access, so please explain as completely as possible. Thanks in advance!

To prevent duplicate records, I use multiple fields indexes, which worked fine until now. I learned that each "empty" fields are consider unique by Access, so not the best in an index to prevent duplicate records. I managed to have it worked using the default value property to give each "empty" records the same value.
Now my problem is that I have a date field which is optional, but I need to use it as a unique identifier in an index. I could again use a default value, but since it has to be a date, I find it confusing. I would rather have a default value of "No date specified" or "-" or even better, "". Unfortunately none of those works with date fields.

dear all
how to calculate a date which is falls on every wednesday using ms access
for eg
this week enter date : 05/03/2007 and then save
next week automatically display date : 14/03/2007
later next time, enter date : 16/03/2007
next week automatically display date : 21/03/2007
i don't think this is the right formula
=DateAdd("d",7,[run_date])
if i keyin run date : 03/03/2007
it will display using above formula : 10/03/2007
but i want display run date : 07/03/2007 ( falls on wednesday )
what if keyin run date : 05/03/2007
it should be displayed : 07/03/2007 ( falls on wednesday )

I track my daily work in an access data base. very simple. each day I enter the date, activity, the person I was helping, and a value ie. 1.5 hours etc.
I might work on the same project many times that week, i.e. 1.5 hours on Monday, .5 hours on Tuesday, and 1.0 on thursday.
my new boss wants a weekly summary. so I need to create a query that would show the total for this activity 3.0 hours for that week. So basically at the end of the year, I would have a query with activities by row, weeks across the top i.e. 52 columns, and the total of the various activities summed up for each week.
I looked at all the standard date functions, and did not find a weekend type functions.

Hi, All...
Can someone tell me how to calculate a future date in a bound field on a form? The form includes "date created", "life expectancy" and "review date" fields, all bound to the same table. I want the "review date" to be calculated by adding the "life expectancy" (number field, in days) to the "date created" field. I found some posts that were similar but none using bound fields.
Thanx so much for you help with this...I've spent quite a lot of time trying to come-up with a solution...to no avail.
Thanx ;<)
Karen
