Queries :: Access 2007 - Select All Dates Between Two Dates?
Apr 9, 2015I have a table of records, which has within it two date fields (effectively, a 'start' and 'end' date for that particular record)
I now need to create a query to perform a calculation for each date between the 'start' date and the 'end' date
So the first step (as I see it anyway) is to try to create a query which will give me each date between the two reference dates, in the hope that I can then JOIN that onto another query to perform the necessary calculation for each of the returned dates.
Is there a way to do this?
So basically, if for a particular record, the 'start' date is 01-Apr-2015 and the 'end' date is 09-Apr-2015, can I produce a dataset of 9 records as follows :01-Apr-2015
02-Apr-2015
03-Apr-2015
04-Apr-2015
05-Apr-2015
06-Apr-2015
07-Apr-2015
08-Apr-2015
09-Apr-2015
(The *obvious* solution would be to create a separate table of dates, from which I could just SELECT DISTINCT <Date> Between #04/01/2015# And #04/09/2015# - but that seems like a dreadful waste of space, if that table is only required to generate the above? And it would have to cover all possible options; so it would either have to be massive, and contain every possible date - ever! - or maintained, adding new dates as necessary when they are required. Seems horribly inefficient!)
Is it possible to just select each date between the two reference dates? Or can you only query something which exists somewhere in a table?
ASP, Access, And Future Dates
Oct 25, 2005I'd like to create a recordset from an Access database that reads the 'Date' field and only selects dates in the past. That way I can enter info ahead of time, give it a date of a week from now, and know it won't show up on my pages until next week.
It should be simple, but what I have isn't working. Here is my code:
Query = "SELECT Id, Date, Info FROM OldNews WHERE DateDiff('d', Date, date()) <= 365 ORDER BY Date DESC"
It lists all the records that are 365 days old, but it still shows any future dates as well.
Does anyone have a better idea?
Thanks!
Access Database Help With Dates
Jul 18, 2007I have a database that includes dates in a table, and a form that I use to show items that are issued from a supply crib. The date is automatically input by the database. I have designed a report with all the data that I need. My problem is that I need to be able to print this report according to a specific start date and end date (which is usually a 7-day period), and I can't seem to get this accomplished. Could someone please guide me in the direction that I need to go? I have a query designed, but I don't know how to apply the query to my report. For example, upon opening my report, I need it to ask me for a start date and an end date, and print the report according to the dates that I input. At the present time, the report won't ask me for these dates. Any help would be greatly appreciated.

Aug 4, 2015I have is rounding down dates in Access. I seem to be having trouble with the equation I built below:
Months Remaining: IIf(Date()<[Anniversary],Round(DateDiff("m",Date(),[Anniversary],Round(DateDiff("m",Date(),[Anniversary]+12)))))
My goal with this formula is to produce a number of months remaining (rounding down) by subtracting today's date from the anniversary date. The Round function I put in there seems to not work as the result is the same when I remove it.
Another thing I am also trying to accomplish is having the date pushed forward if todays date is greater than the anniversary date. In this instance, I tried adding 12 months to get it back on track. So say the anniversary date is july 4th 2015 and todays date is aug 4th 2015, well thats gonna show negative 1 but if I add 12 it should bring it to 11 months remaining -which would make sense because the anniversary month and day is fixed but the years just get pushed.
Access Constraint: Overlapping Dates
Sep 9, 2005Hi,
I have developed a small hotel booking system which inserts records into a reservations table. The table looks like this:
[ReservationNr][StartDate][EndDate][RoomNr]
I am now trying to add a constraint which prevents a room from beeing booked twice on the same day, hence the time period defined by StartDate and EndDate in a record must not overlap with another record.
Is Access capable of adding such a constraint?
It was easy to add a constraint that prevents a booking where the StartDate is before the EndDate, but this one needs to reference already existing records.
Any help would be much appreciated.

Calculate Working Time Between Dates In Access
Oct 26, 2006I have searched the forum for this answer but no luck. :(
I'm trying to calculate the amount of WORKING time between two dates in an Access database. At the moment i am just subtracting one date from another but this gives me all of the time in between including weekends and evenings.
I need this time to be calculated in hours.
In Excel i know there is a NETWORKINGDAYS function which does something similar but with days rather than hours.
At least if i could get the working days i could then convert it into hours.
Please help!

Jan 24, 2008Hi, I am a longtime Excel user, and am now migrating some work to Access.
I have 2 fields dealing with dates in the format mm/dd/yyyy hh:mm, OPEN and CLOSE
I'd like to get the difference between the two in hours, but I have no idea how or where to do this in Access. I'm assuming it is put into the queries, but it would be easier if I could just put it in the table.

I want the result to be "25"

MS Access Query Help. Expression For Calculating Multiple Expiration Dates.
Feb 28, 2008 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.

Queries :: Select All Dates Since A Given Date Without Referencing A Table? (Access 2007)
Apr 23, 2014Is it possible to create a query to select all dates from a given reference date? I don't mean all dates in a table - I mean all dates generally?
(The idea being to fill the first field in the resultant dataset with the list of dates, then run subqueries off that to fill the remaining calculated fields)
I'm currently using a date field in one of my tables to populate this first field (the full SQL is in a separate thread here)
But that was just a convenient way of getting a list of dates; the dates in that table don't actually have any significance to the resulting dataset (other than they should roughly overlap with the dates I'm looking for)
The flaw in that method is that the table from which I get those dates can only ever have dates up to and including yesterday. I also need to get today's date in there (and calculate the subqueries based on that date as well).
It's also possible - although unlikely - that there could be random dates missing from that table as well - in which case I need to plug those gaps and calculate my fields for those missing dates as well.
For clarity; that first field (AsOfDate) should contain every weekday from the earliest date in that table (i.e. Min([tblBalances].[BalanceDate]) up to and including today. It doesn't matter if any of the dates inbetween are missing from tblBalances as the subqueries will just return zeroes for those dates (which is exactly what I want to see).
Subtracting Dates From Adjacent Dates In Same Column
Sep 7, 2006Hiya-
I have a database with 5000 entries, corresponding to about 10 entries for about 500 people. Each of the entries is dated, and I need to calculate the time intervals between each person's sequential entries in the table.
One way of doing this is to create another column that contains the date of the previous entry. I can then use DateDiff to subtract one date from the other and give me the difference in days.
This approach falls down if I then work with only a subset of the entries - I would have to re-enter the previous entry dates as the time intervals would have changed.
What I really need is a way of subtracting the date from the date in the cell directly above it. Will Access let me do this, or is there a better way?
Many thanks, Jules.
Queries :: Count Dates Between Dates In Two Tables
Jul 8, 2014I have two tables with dates. Between (!) every two following dates in table1, I want to know the number of dates in table2. How do I write an SQL query for this? The tables I have are up to a few hundred records in table 1 and a few thousand records in table2. So to prevent that this takes hours I need a fast query.
To explain the query I need, for example:
table1
01/01/2014
15/01/2014
17/01/2014
30/01/2014
table2
01/01/2014
02/01/2014
05/01/2014
17/01/2014
18/01/2014
20/01/2014
21/01/2014
25/01/2014
So the answer of the query would be 2,0,4.
Explanation:
Between 01/01/2014 and 15/01/2014 in table 1 there are 2 dates in table2 (01/01/2014 is not included between the dates)
Between 15/01/2014 and 17/01/2014 in table 1 there are 0 dates in table 2
Between 17/01/2014 and 30/01/2014 in table 1 there are 4 dates in table 2
Summing Data Between Two Dates (When Dates Are Different Per Record)
Nov 15, 2011I have a master table which shows all transactions per record (person) over a financial year.
Each record person has a seperate package period over which their spend needs to be measured. Therefore although I have all their transactions for the year, I only want to sum their transactions between their given [start date] and [end date] which are in columns.
I need to be able to create a field which sums all expenditure per record between the start and end dates
Name Start Date End Date Invoice Date Amount
Matt 15/5/11 15/9/11 1/11/11 £100
Matt 15/5/11 15/9/11 7/7/11 £200
Matt 15/5/11 15/9/11 12/12/11 £200
In this case I would only want to sum 7/7/11 as this is between the start and end dates
I want to write something like sumif([Invoice Date] is between [start date] and [end date] - not sure where or how exactly
(The start date and end date will always be the same per person)
Is this possible in access?
Returning All Dates Between Two Dates In The Same Record?
Nov 3, 2005Hi,
Please bear with me here as it's a little involved.
I'm doing a staff profile website which includes a section where they can enter their annual/other leave details.
I decided to store their leave in two fields Start_Date | End_Date rather than each individual date that they took - the short and wide approach vs long and narrow.
This has left me needing to do a query that would return all the dates between the start and end dates inclusive.
Example:
StaffID---Start_Date---End_Date
---1-----12/12/2004--14/12/2004
Returns:
StaffID---Leave_Dates
--1-------12/12/2004
--1-------13/12/2004
--1-------14/12/2004
I appreciate i could do this using some script to loop through a recordset and build an array of dates but i wondered/hoped that it could be done using SQL.
As it is an asp page i can't use user defined functions in a VBA module in Access so the solution would need to be pure SQL.
Is this possible?
Any help v.much appreciated.

Multiple Min / Max Dates By Sequential Dates
Apr 4, 2012I have a scenario where the first three rows of date which have dates of 4/1, 4/4/ 4/6 with ndc 5513026701; next six rows that have dates from 4/8 to 4/20 with ndc 5513014801; next three rows that have dates from 4/25, 4/27, 4/29 with ndc 5513026701.
The issue I am having is I do not know how to have separate min/max dates for ndc 5513026701 since when I group by ndc 5513026701 min = 4/1 ; max = 4/29. I need to have min = 4/1 and max = 4/6 for one row and another row of min = 4/25 and max = 4/29.
Any easy way to sequentially create min/max for each ndc 5513026701? I wasn't sure how to verbalize this so I have attached a sample worksheet.....
Modules & VBA :: Process Records Without Dates First And Then Run Another Process To Split Those With Dates?
Aug 18, 2014I'm not sure if I am biting off more than I can chew. I have a text field in each record in my database (Inherited) The db has nearly 5,000 records. I would like to split the field into records in a seperate table. An Example of the table as is now;
Code:
MemberIDBoats
5882Opossum(78-80) (87-89) Otter(80-84) Opportune(91-93) Turbulent(97-00).
5883Astute Auriga Aeneas Affray Amphion
2407H34 O10 Porpoise Trenchant Tapir.
I want to create a table as follows;
Code:
MemberIDBoatFromTo
5882Oppossum19781980
5882Oppossum19871989
5882Otter 19801984
5882Opportune19911993
5882Turbulent19972000
5883Astute
5883Auriga
5883Aeneas
5883Affray
5883Amphion
Etc.
Is this possible in one hit or do I need to process the records without dates first and then run another process to split those with Dates? I say dates but the field is a text field. About 15-20% of the records contain dates which are always enclosed in parenthesis.

Queries :: Find A Way For Access To Find Unique Dates And Unique Names?
Aug 1, 2014I have been working on a simple data base for some time now (beginner level) and am still trying to improve it. I would like to do something but before that I would like to have your opinion to know if it is even possible?I have a query QryMainReport:
Start Date/Time
End Date/Time
Employee
At the moment this is what the format of my report looks like (I removed other unnecessary fields):
StartTime----------EndTime---------------Employee
12/06/2014 01:00--12/06/2014 03:00------John Smith
12/06/2014 04:00--12/06/2014 06:00------Jane Doe
13/06/2014 02:00--13/06/2014 05:00------John Smith
13/06/2014 08:00--13/06/2014 08:00------Jane Doe
I would like to do as a report. (Dates would always be from Sunday to Saturday). I am not sure it is possible to do that. I suppose first it would mean:I would have to do a query to separate the times from the dates?I would have to find a way for Access to find the unique dates and unique names?Does it mean I have to use cross tab queries?
Can You Query A Range Of Dates With A Range Of Dates
Mar 17, 2008I have a client that wants to enter a range of dates in a query of when they will call that person back. Then they want to be able to type in a range of dates and have a make table query show them all the people that fall in between these two dates....is this even possible???
Ex.
Joe March 3 to March 8
Mary March 4 to March 9
John March 5 to March 10
So if they type into the query March 3 to March 6 all three people should show up because one of the dates specified lies within the parameters they are asking for.....man I am out of ideas
Anyone.....
