Mapping Week Numbers And Dates
Mar 27, 2007
Hello thank you for reading my question
I am setting up a database for a training centre, part of this includes registration
The academic year I am working with runs over 36 weeks with 24 teaching weeks, 2 x 3 week holidays, 2 x 1 week reading weeks and the final 2 weeks for exams.
I aim to set the system up so that when a user opens the application, I get the username from windows, the day and time then open the correct register. That bit should be fine.
As I have 36 weeks I want to some how map the week numbers to the dates at the start of the term and also the holidays. There are 2 reasons for this, the first being so that when the user logs in the register only shows the current week instead of needing to search along all 24 or 36 entries, the other reason is so that when checking the whole register the holidays are not shown.
Does anybody have any suggestions or pointers as to how I can do this?
Thanks

I am trying to write some VBA to convert a date into a week number.
My work colleagues do not not what system is used to define the week numbers. So I have gone through all their records for a few years and deciphered this pattern:
I need the code to define that there are 52 weeks in a year. The last sunday of Dec is the beginning of Week 1 for the following year. Except when it is a leap year where Week 53 exists. otherwise it only goes up to week 52.
Start day for the week is Sunday. End day is the Saturday.
Some examples to check against:
22nd December 2013 = Week 52 2013
29th December 2013 = Week 1 for 2014
----
21st December 2014 = Week 52 for 2014
28th December 2014 = Week 1 for 2015
----
20th December 2015 = Week 52 for 2015
27th December 2015 = Week 1 for 2016
----
25th December 2016 = Week 53 for 2016
1st Jan 2017 = Week 1 for 2017
-----
Tried various methods already
iso 8601, wrong week start day
intWeek = DatePart("ww", datDate, vbSunday, vbFirstFourDays) Was right for 2013 but wrong for later dates.

Hi everyone,
I want to calculate the week number of a date in a year starting from the 1 July (of the current year) - as this is the beginning of the Financial Year in Australia.
The starting day of the week is Wednesday.
I've been trying to think how I could use the Access DatePart Function in a query to calculate the week number from sales records.
I have had no trouble calculating the week number from the 1 Jan using the DatePart function. However, the function doesn't allow me to select a different date other than the first week of January.
So as a work around, I've thought of calculating the week number of 1 July in the current year, and just using the DateAdd function to add the week number to the week calculated by the DatePart Function.
Not quite working yet. Here's what I've come up with so far.
WeekNumberCount: DatePart("ww",[DateCalled],4)
I use the following to calculate the "my" starting week of the year:
StartingWeekInYear: DatePart("ww",DateAdd("ww",0,"1-July-" & Year(Date())),4)
Then I add the two together together:
MyWeekNumberCount: DatePart("ww",[DateCalled],4)+DatePart("ww",DateAdd("ww",0,"1-July-" & Year(Date())),4)
I know it needs some work to be useful for all years. Any suggestions?

Is it possible to query using the week number in the year as criteria. For example instead of putting 13/05/05 to 20/05/05 can we use week 12 - the idea is to save on keying info in each time.

I've restructured my 'application' to have one table and a lot of query/forms. In light of not figuring out the combo box situation I altered the requirements and what I needed thinking I may have an easier go of it, but alas not exactly my experience. I have 5 reports that I want to filter them by week(start of the week). I have a function which can turn any regular date entered to the start day of the week(monday). I thought my best way about this would be to fill a combo box with all the accepted dates through a separate table's column.
Is there a way to pop a dialog box when the user clicks to generate the report that will prompt them to choose a week then run that criteria against the report and only bring back that date?

I would like to enter a week dates forward after looking up the last entered date. i have working codes that looks up the last date and increments it by one and enter the date into a new field.
Here is what i have:
Private Sub Form_AfterUpdate()
Dim dtmNextDate As Date
Dim dtmLastDate As Date
Dim SDate As Date
LastDate = Nz(DMax("[SDate]", "schedule"), _
DateAdd("d", -1, Date))
NextDate = DateAdd("d", 1, LastDate)
CurrentDb.Execute "INSERT INTO Schedule(SDate) VALUES ('" & NextDate & "');"
End Sub
enter dates into 5 new fields instead of one using a loop maybe.

My dates are stored as numbers (long integers), because they need to be in the form YYYYMMDD, and I couldn't figure out how to enter them and keep them in that format as Date/Time.
Anyhow, I have a form with a textbox and a button. When the user enters in a date range, I need totals to show up for only dates that are in-between and/or equal to the date(s) typed in the textbox.
For example when the user types in 20050904-20051004, and pushes the button, a display of totals will be displayed for only those dates and those in-between. If the user leaves the textbox blank, and pushes the button, I want totals from all dates to be shown.
As you may know from my previous question, I am a relative newbie to Access. Suggestions about how to do this maybe even how to derive and present the totals, and especially specific code will be very helpful and VERY much appreciated.

hi,
I have two tables named "Uni" and "MainTable"
"Uni" has two fields, named "A" and "B".
"MainTable" has three fields, named "aa", "bb" and FinalAns"
Uni
A | B
-------------
001 | 444
004 | 999
042 | 129
MainTable
aa |bb |FinalAns
--------------------------------
001 |XX|? - should be 444
042 |XX |? - should be 129
Below queries code is written by me:
UPDATE MainTable set [MainTable].[FinalAns] = [Uni].[B]
WHERE [MainTable].[aa]=[Uni].[A]
But it does not works, it prompted me "Enter Parameter Value Uni.B" and then "Enter Parameter Value Uni.A"
Can anyone teach me how to solve my problem? - can be using macro or vb code or queries.

Issue: We have software that maps some of our "custom" grades that we use locally to the state-specified grades when we submit.
Ex: Grades PA and PP map to report to the state as PK. The data stays in our software as PA and PP however as it is needed that way.
I'm trying to run queries comparing our data with what is at the state to head off mismatches and want to find a way to NOT have these grades show a false mismatch. The field for flagging as mismatch is for example
GX = iif ([schoolgrade] not like [stategrade], "GRD", null)
I tried doing a compound iif statement in my comparison query field but got stalled there as there are 6 or 7 grades that map, one with 3 that maps to one state grade.
What would be the best way to alleviate these? I know I can do a change query, but I'm assuming that can only be done one at a time, and I would have to import the data. Doing find and replace is too manual, and the data is updated daily so I would want something automated.
At this point I'm thinking of creating a bunch of change queries and automating the running of them but that seems like the long way to do it...

I have designed the database i wanted but now i want to link the fields from a access form to a pre designed template i designed in both microsoft word and pdf. When a user types the information in and clicks preview the information typed in access field will match the field in the template any ideas or software programs that do this.

I've created a report based on a query that shows me the jobs that have been added to tblJobs between two selected dates.
The report works fine and displays all the information I need, however other than being sorted by day of the week i.e. Monday, Tuesday, Wednesday etc. The records just run on one after another.
I want to create a page break, so that a full week is shown on a single page before then forcing a new page when it moves in to the next week.

I have built a Database links to multiple back end databases. The whole database is completed, and I have to share it across the company, so I have placed the Database and all of the Back End databases on a "public" shared drive. I have the "public" drive stored as my Q drive. So when I link to the back end databases, the path it stores is Q:DatabasesDatabase.accdb
However, the problem is that not everyone will have the "public" drive mapped to Q. It's possible they could have it mapped to P or A or whatever. So if someone has their "public" drive mapped to P, this database will not work (since Q:DatabasesDatabase.accdb would not exist for them - it's really P:DatabasesDatabase.accdb).
Is there a way around this? So that instead of it mapping to the relative letter (Q or P), can it just refer to "public"?

I have a query that groups records by date into week numbers using the following expression.
WeekNumber: DatePart("ww",[Date],2)
I would prefer to display the result as the week commencing Monday date.
How?

I have the following expression which works nicely to group all of my dates into their respective weeks of the year, by week dates beginning Mondays:
WeekStart: ([MyDateField]+1)-DatePart("w",[MyDateField],2)
However, since the week beginning 12/26/05 crosses over both '05 and '06 (as week 53 and week 1), I get two groups of dates recorded for the week of 12/26/05 when I run my query.
Since my chart is based on weekly totals, I can't have two separate totals with the same 'week beginning' date.
How can I adjust my code to get one total group of dates for the week of 12/26/05?
Help greatly-needed!....

I'm having multiple problems with my database like things such as -
i'm currently working on the Query 2 - On the Phone database (ignore Query 1) and i want to search for multiple plot numbers preferably in one parameter prompt with a comma to seperate numbers. (this could be a multitude of numbers so i would like to be able to input as many as needed). Also when i do search on this query since the Criteria is a 'Between' Value i would expect everything between the 2 numbers input to show up - but a lot of numbers out of the range show up too - why is this? (The Numbers are like "69 to 136" and they will show up - but 1-69 and 136-170 would too
I would also like to implement the search results from Query 2 into the Form i currently have made but it just opens up a access table when the search is made?
i cannot link my database as it is too big for the server - But here are the Criteria for Query 2:
Plot No - (criteria = Between [Enter First Plot No:] And [Enter Last Plot No:])
Site - (criteria = Like "*" & [Enter Site:] & "*")
Product - (criteria = Like "*" & [Enter Product:] & "*"
The Query is the one im most concerned about , i can live without a form.

Ok so in excel I have some numbers that are stored as text. The reason being that they are zip codes and some begin with 0 and excel doesn't want numbers to start with 0....so when I import these into an access field that has an input mask for zip codes...will it convert these correctly since the field is a text with input mask?

I have 2 fields that I would like to automate if possible
One field is called "p/o number" and another field called "line no"
These fields are part of an ordering database
Let say I have 200 items to purchase form 10 suppliers
And form example 20 items from each supplier
What I do at present is put the order number on each line item and the line number
example
p/o number line no
1 1
1 2
1 3
2 1
2 2
2 3
2 4
What I want to do is just put the first po number in the required line . Put the first line number in i.e. "1" and the macro will complete all the p/o numbers and line numbers for me as per the ones marked in red.
Example
1 1
2 2
3 3
2 1
2 2
2 3

Any way to have a form with Dates as column headers to update a table where the dates are stored in rows???
The table set up is like this:
tblOpHdr
DiaryID (PK) - OpDate (Date)
tblOpDetail
DiaryID (FK) - CostCode - MachineNumber - MachineHours - etc
I'm just wondering if there's any way I can do this with a datasheet or a crosstab type setup?
It's Access 2010.

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
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?

Hiya-
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.

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
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

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)
Is this possible in access?

I have a table with fields like this one but the weeks go all the way up to 52. What I am trying to do is count the number of consecutive zeros and if it is more than five, count how many of the following fields have a number in them and if that number is less than the number of zeros preceding it identify that person.
For example Joe would be identified below because he had 6 consecutive zeros and then he had 5 weeks of numbers immediately following the string of zeros. Bob would not be identified because he had 5 consecutive zeros and then 5 sets of numbers immediately following the string of zeros so the zero frequency isnt higher than the number frequency immediately following.
