Queries :: Access 2007 - Select All Dates Between Two Dates?
Apr 9, 2015
I 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
(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?
Is 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).
Hi, everyone, this is my first time be here, I'm glad that I found a good place to learn ACCESS.
I found this DB sample in here http://www.access-programmers.co.uk/forums/showthread.php?t=103312 but if I try to add two text box in the mainform to query startdate and enddate, how do I make it.
such as: I want to find title is manager and sex is F and datebirth from 1965/1/1~1973/12/31.
I'm lack skill in Access and tried to find this answer for a long time, every suggestion will be appreciated, thanks so much in advance.
I have built a query to calculate the expiry dates of training courses but I am trying to input a criteria so that only dates within 90 days of todays date show. I am using Date()<90 but it doesn't return the correct information. What the criteria should be for this?
I 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
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
I have a table of logged entries. Each record has a date field (ValueDate) and an account identifier field (AccountID)
I also have a table of rates. Each record has the same account identifier field (AccountID), a date field (EffectiveDate) and a rate field (BankRate)
Entries can be logged for any given ValueDate. But there may or may not be a corresponding EffectiveDate in the rates table.
I need to write a query that will return all of my logged entries and the largest EffectiveDate which is on or before the ValueDate (as well as the BankRate corresponding to that EffectiveDate)
This is as far as I've gotten but it returns multiple records for each logged entry. I need one record per logged entry.
Code: SELECT tblLoggedEntries.EntryID, tblLoggedEntries.AccountID, tmp.BankRate, MAX(tmp.EffectiveDate) AS EffectiveDate FROM tblLoggedEntries LEFT JOIN (SELECT tblRates.AccountID, tblRates.BankRate, tblRates.EffectiveDate FROM tblRates) AS tmp ON tblLoggedEntries.AccountID = tmp.AccountID WHERE tmp.EffectiveDate<=tblLoggedEntries.ValueDate GROUP BY tblLoggedEntries.EntryID, tblLoggedEntries.AccountID, tmp.BankRate
I have a form and table which I use to collect some reservation information. I then have a subform/table which I use to enter the actual dates of for that reservation. This subform/table has only three fields. The foreign key field that links it to the main form/table, the date(s) entered and the subform/table autonumber primary key.
What I would like to do is use an ActiveX type of calendar as the subform and be able to select a range of dates. If someone is making a reservation for 8 days, I want to be able to select that range of days on the calendar and have create/enter all 8 of those records in the subform/table.
I would much prefer this as opposed to simply collecting a single IN date and a single OUT date.
I am trying to build a form that accepts either a single date for start and stop dates whilst allowing a range of dates to be selected for operations that cover several days. I am using the Access 2003 calendar which is fine for selecting a single date but how do I select several dates (4-7 Mar for example) ?
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?
I 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)
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.
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.
I 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.....
I need to create an expression that will limit the results of my query. I only want to display all records where 'Completed' date falls within the following criteria: Between the 1st April and the end of last month. I do not want to include this month, because by definitiion it is not complete - not a full month.
My head's just a bit mashed and I can hardly begin to work this out.
If you can help me out, I'd appreciate it.
If you have the time I would also like to find the average number of records completed per month as so will need to somehow determine the number of full months between the 1st April this year and today.
I'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;
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.
I have set up an Attendance database at work, where a record is created for each member of staff when they are absent. The tables are set up as follows:
What I want to be able to do is set up a query to search for a reason for absence on a certain date (btw my date format is set at dd/mm/yyyy). The problem I have is if the user needs to check a date in between the start and end date i.e. Start Date is 11/11/2005 end date is 11/12/2005 and the user checks on 01/12/2005 then this record will be found.
I know there is a simple way to do this but I can't seem to figure it out. Any help would be greatly appreciated!
I have two date fields. I want to subtract them to determine the number of days elapsed. The dates are in the following format: Dateserial (Year, Month, Day). When I subtract them I get 7670 as the result when the number should be 365 if they are a year apart. How can I subtract the dates in a query?
My form consists of a textbox with a selected date. I have a combo box with integers 1-15. I have a table with 15 people and their birthdays.
I am trying to find the birthdays after a selected date by the integer selected in the combo box. For example, if I select 2/1/2013, and pick 7 in the combo box, the subform should show me people with birthdays 2/1 through 2/8.
I have a query with a datediff function. This is my query expression Expr1: DateDiff("d",[DateofBirth],[Forms]![Calendar]![Text1]) The criteria is <=[Forms]![Calendar]![Combo3].
It displays some data, but it's not consistent at all. I'm hoping to fix this without any SQL changes or form code. But if that's what I need, I'll do it.
Im using Access 2002 to revise my SQL. But it seems I have an issue with the way dates are being interpreted by Access whilst using SQL mode for Queries.
I typed the following code to add a record to my database:
INSERT INTO pt_mstr (pt_part, pt_added) VALUES ('TimsPart', 01/01/2005)
Sure enough it creates the record. But for the field 'pt_added', I get the value '0/01/1900 12:00:43 AM'. (Nb I exported the data to Excel and this is how it interpreted it.)
Changing the date I am inserting into the database only changes the time value of this enlongated piece of data.
I imagine I have missed something really simple here.
I have a table tbl_PolicyDetails with details of the policy the customers have with us.. In the tbl_PolicyDetails, I have two fields (these are the ones in question) called
"policyStarted" - Start Date of a Policy and "policyPeriod" - Term of Policy Monthly/Annually/Quarterly
So in a Form view I just get the Next installment for the customer based on this information for display.. For example..
Mr Butters Stotch's policy started on 26/04/2013 and is paying Quarterly; the next (i.e. 2nd) installment would be on 26/07/2013..
Ms Wendy Testaburger's policy started on 07/04/2013 and is paying Monthly; the next (i,e. 3rd) installment would be on 07/06/2013..
This is not hard to get.. I have that sorted.. But the problem is, my manager wants to be able to specify two dates and search all policies that will be 'paying in' that Date range should be picked up..
So if the search range happens to be.. 01/07/2013 and 31/07/2013 Then Mr Butters Stotch's policy should be picked up, as his next installment falls on 26/07/2013.. Since this information is not stored, I cannot run a direct Query on this.. Also as the Installment number varies for each customer, I would not be able to just add 1 - Month or Quarter or Annum, and see if the date falls in that range..
I just can't seem to get this one to work right. I've got the following query. I need to count the number of Null dates or show zero if there are no Null Dates.
Code: SELECT DISTINCTROW qryNoticeResponseNew.fldNoticeID, Count(qryNoticeResponseNew.[fldResponseSeen]) AS fldCount FROM qryNoticeResponseNew GROUP BY qryNoticeResponseNew.fldNoticeID;
Which is just counting the number of dates so far. It got me to thinking I need to do something like this.
Code: SELECT DISTINCTROW qryNoticeResponseNew.fldNoticeID, IIf(IsNull(qryNoticeResponseNew.[fldResponseSeen]),1,0) AS fldCount FROM qryNoticeResponseNew GROUP BY qryNoticeResponseNew.fldNoticeID;
Which pops a "cannot have aggregate function in expression" error.
I've got two tables, both are indexed by customer ID, with a series of dates against the customer ID. One has a list of all dates a customer was visited, the other is a list of dates where activity happened on the customer account
I want to get a list of the dates when the customer was visited but where no activity happened on the customer account, i.e. where there is a customer visit date on the customer visit table but no record for that date on the activity table.
How do I do that? I can find all dates where was a date was on both tables, but how to find where its on one but not the other
