I need to perform a query that works out how far in advance people book holidays. I have the arrival date and also the booking date, and I think I should be using DateDiff. However, I tried to put it in an existing query and it hasn't worked:
SELECT Bookinfx.[Park Name], Bookinfx.[Accom Type], Year([Start Date]) AS FilterYear, Count(Bookinfx.[Park Name]) AS Bookings, DateDiff("d", [Booking Date], [Arrive])
FROM Bookinfx
GROUP BY Bookinfx.[Park Name], Bookinfx.[Accom Type], Year([Start Date])
HAVING (((Year([Start Date]))=2004));
Hi there. I'm just jumping into Access and have the following question. In my Purchase Order Table, I have a date field calcualated as text, i.e. "01/12/04". I need to convert this to a date format in my queries so I can do calculations, i.e. 01/12/04 - 01/05/04 = 7 days. Can someone help me with how to convert this text date to a date format. Sorry if this is an easy question. - AJS
I am creating a database from an Excel Workbook. Many of the calculated cells are dependent on the values of other calculated cells.There are more than 255 cells for the one sheet so I can't use one table.I was forced to use multiple tables and place the calculation fields in their own tables for the use of their fields in a calculating query, although they won't be seen on any form or report.
What is the best way to relate these tables even though they should really be all part of one table? Should I just use a Cross Join? Will a cross join allow me to properly calculate with a field from an unrelated table? What about an Outer Join?I need to reinforce integrity so that if one set of table data is deleted, so are all the others.I have already tried to place a "Report Number" autonumber field on each table, but it doesn't seem to allow me to reinforce the integrity and gives me, "invalid field name of definition of index or relationship".
Hi I would like to manipulate some date information. I have a start date field and an end date field and I would like to draw up a schedule for payment where the Acess takes the finished date and the start date to get total days appart then devides this by a value set by the operator. say If the operator wanted 6 paymes then my total days would be devided by 6 giving me the number of days to add on to the start date. Then with these dates a schedule is made up and the code I have tried looks something like this.
Dim valuation1 As Date Dim valuation2 As Date Dim valuation3 As Date Dim valuation4 As Date Dim valuation5 As Date Dim valuation6 As Date Dim valuation7 As Date Dim valuation8 As Date Dim valuation9 As Date Dim valuation10 As Date Dim valuation11 As Date Dim valuation12 As Date Dim startdate As Double Dim findate As Double
Dim valcounter As Double
'retrieve start date and end date startdate = CDbl(Me.Start_Date) findate = CDbl(Me.Completion_Date)
'calculate evaluation periods Dim valCount As Double Dim valDays As Double
Select Case valcounter Case "1" Me.valuation1 = startdate Case "2" Me.valuation2 = startdate Case "3" Me.valuation3 = startdate Case "4" Me.valuation4 = startdate Case "5" Me.valuation5 = startdate Case "6" Me.valuation6 = startdate Case "7" Me.valuation7 = startdate Case "8" Me.valuation8 = startdate Case "9" Me.valuation9 = startdate Case "10" Me.valuation10 = startdate Case "11" Me.valuation11 = startdate Case "12" Me.valuation12 = startdate
I was wondering if somebody could help with a problem I have come across. I am currently developing a database for a small charity that I work for. The aim of the database is to record when staff undertake counselling.
I have created a query that calculates the current age of a client in the database uing the following expresion:
Age: Date()-[Date of Birth]
The Date of Birth is formated as a Short Date
In the query I have set the format of the column in the query to 'yy'. This then just displays the age of a client. This work fine apart from ages which are less than 30. If the age is less than 30 e.g. 29 it displays the date as 1929.
Does anybody know how I might be able to solve this or an alternative way in which to calculate dates and display it as 'yy'. (Its been a few years since I last work with access so skills a little rusty)
The reason behind the yy is that the monthly & yearly stats have to group by age ranges.
I have a field for 'deadline' date and I need to show all records where the deadline date is within 7 days of todays date. (Obviously todays date will change daily...)
I have tried subtracting the date from todays date but it doesnt work.
Just a quick request for a bit of help. Tries a few things but didnt work.
I have a form which has an employee start date. What I need to do is work out the holiday entitlement of each emplyee. The math behine this is, if they have been here less than a year, we do the following. 20 Days holiday entitlement per year, Divided by 52, then multiplyed by the ammount of weeks remaining in the financial year. eg, (20 / 52 = 0.384615384) * 31 = 11.92 So they would have 12 Days holiday entitlement.
But if they have been here for 12 months or more, they are entitled to the full 20 days holiday.
How would I express this as an expression or query or VBA to calculate this. I just cant figure it out, especially the if been here 12 months or more.
I have the start date, in a tbl called tbl_employees if that helps. ( also in the form frm_employee_details ) Our financial Year runs from the 1st December - 31st November
Several questions here, trying to lead up to the easiest code...
First is I have a table with some dates, and I need to do some date calculations, but one of the dates I need will vary. So I was thinking of having a parameter ask for it. Is this the best method?
Second, then once I have this date in, I'll need to have it subtract from another dated reference in the table to figure out the numbers of days difference. e.g. 05/31/06 - 05/01/06 = 30 Can you get two dates to subtract like that and come up with a general number field? If so, then will the dates have to be text, converted to numbers, or can stay as dates?
I've tried several methods and have been quite unsuccessful in each attempt.
I am trying to write a query that will return all records whose field expiration_date meets my criteria. The criteria is If expiration_date - 5 years < today's date then.... do you subtract the total days? months? Any help would be appreciated.
I am building a database and in it I need to do date calculations. Without too much detail I input a date based on the built in calender from the date/time field and based on that date I need to have the following data returned into other individual fields: 6 months from that date, the days until that date, 2 months from the date input, 4 months from the date input, 5 months from the date input, 60 days from the end date, 45 days from the end date, 30 days from the end date, and 15 days from the end date.
Example: I input "Sep 10, 2015" and I would get "Mar 10, 2016", "181 Days", "Nov 10, 2015", "Jan 10, 2016", "Feb 10, 2016", "Jan 10, 2016", "Jan 25, 2016", "Feb 9, 2016", "Feb 24, 2016".
I have read through websites regarding date calculations within Access but I cannot find the specifics for the application that I need.
I need to calculate (in a query) the Actual Time of a job. I have the start date, start time, end date & end time (all separate fields). This seems to works ok by subtracting the start from the end.
Then I need to calculate the Estimated Time (time it should have taken). This is done by taking the Quantiy divided by the Rate-Per-Hour. This seems to work out ok in the Query, e.g., 101000 / 15000 = 6.66667 hours. But when I display this result in a report as a "Short Time", I get 16:00 instead of 6:40. How can I get the correct display? The other problem is that I need to divide the Estimated Time by the Actual Time. This also gives me wierd results - I suppose because one is a decimal format time and the other is a "Short Time" format. How can I get the correct answer?
I have solved the problems getting values on the subform. I have not in getting values on the subform.For instance, on the one titled phone use the formula in the tutorial is:
=[sbfCustomerRoomUse].[Form]![txtTotalPhoneUse]
#Error results when the doc is put into a form mode.
Now when I input each value in the equation above separately.I still get no entry.
For " = sbfCustomerRoomUse" , I get #Error; and for "= txtTotalPhoneUse", I get #Name.
CustomerRoomUse and txtTotalPhoneuse are from the subform that was dropped into the customer form in a previous step. It shows that explicitly when designed sbfCustomerRoomUse on the main that CustomerRoomUse come from a subform. This does not seem to need to be done with txtTotalPhoneuse, and I am not sure why. Neither one gives me a desired calculation result.
I'm trying to get my "IncidentDate" field to autopopulate two other date fields to a few days from the "IncidentDate". The other two date fields are "ContainDueDate" and "RootDueDate". I'm trying to accomplish this on my "Test CAP Form"
I tried using the following in the BeforeUpdate of "ContainDueDate" and received a complier error: expected =
Code : DateAdd(d,2,[IncidentDate])
so I removed the parenthesis and nothing happened
Code : DateAdd d,2,[IncidentDate]
I even tried redoing it in the AfterUpdate of "IncidentDate" and nothing happened either
Code : DateAdd d,2,[ContainDueDate]
I'm not sure if I'm even using the right function to get what I want.
I have an odd problem that has stumped me for several days. I'm working on a form that contains a chart. The chart is based on a query, which is based on another query, which is based on a table. In the top query, I need to put some calculated fields that operate on other fields. But when I try to multiply two fields together, I get Null. I'm pretty confident that the fields I'm operating on are numerical.
I am creating a repayment schedule (as a report) and I want to display a series of fields as a column which return (show) a date one month after the date in the field above.
The first repayment date field (Line 1) will show a date one month after the loan was paid out. the Next field below will show the date one month later.
I can't simply insert the "Date + 30" because that would get out of since over the year. If the loan was issued on say the 15th of January, I need the first field to display 15th February and the next would be .... 15th March.... Yes - You've got it!
Now I could do that in Excel, but I don't know how to get Access to do it.
I am currently building a booking and invoicing database for the small business where I work. One aspect of this database allows you to enter an employee name and schedule days off via a form I have already built. To access this information I would like a parameter query where you can enter a date once and then have this date looked up across a number of date fields. Here are my table column headings:
ID Employee Name Date 1 Date 2 Date 3 Date 4 Date 5 Date 6 Date 7 ....etc
So, basically, the parameter query would ask "What date?" which the person would enter, and then search all 12 date fields to see if the date was contained in any one of them. Then it would pull any records which did have the date in one of the fields.
It seems really simple but I have searched and searched and can't seem to find the answer. Tried a multivalue field but does not seem to work.
Thanks very much, any help appreciated! Elspeth :confused:
Ok let me explainI have a list of 50 people who may have accessed events A,B,C at different times but what I want to do is to put a date in my form, run the quaery which will list all people who have Attended A,B or CWhen I do my normal query, I put the fields in, but if I put a date filter in Event A, it will not show up any person who may have attended event B but not Event A.I thought about running an append query but this would mean running the data several times with possible duplication of client names.Ideally I would like to have my report to showDate: 31/07/2006Name A B CK.Brown Y YJ Blogg Y YK Smith YK Ellum Y Ythen I can just use a count at the bottom :)The methods I have tired will filter event date A, but will not show J BloggIf I create another append for Event B, and append that data to a table, then I will have duplicaion of K Brown.. Any Help Appreciated.Last thing - when I run the append queriy and get my duplications, the fields where I had a Y/N option - if it was YES then I get a -1 instead of 1 ??? Why? and how do I make sure that when appending that the Y answer is a 1 not a -1
Working in MS Access 2010. Data must be entered and updated in Access only. Trying to figure out if it's even possible to auto populate dates in multiple fields in a form that are triggered when I enter ANY date in a primary date field on the form. I have close to half a dozen fields I'd like to do this for but here are a couple of the fields I'm working with:
Re Insp Date 90 Day Notice(Form field to be triggered and show a date 90 days prior to the trigger date) Re Insp Date 60 Day Notice (Form field to be triggered and show a date 60 days prior to the trigger date) Re Insp Date (Trigger date)
What I'd like to do is enter values in the "Re Insp Date" field (in the form) and have it trigger/auto-fill/auto-populate the "Re Insp Date 90 Day Notice" so that it shows the date 90 days prior to the "Re Insp Date" and the "Re Insp Date 60 Day Notice" so that it shows the date 60 days prior to the "Re Insp Date"........all this, and have it auto-update the queries and tables its linked to.
I've tried looking online and in instructional material to see if there is a formula, equation, macro, an expression or VBA coding that I can use to execute this but am having no luck.
The MAIN OBJECTIVE is to have the the linked query and table update automatically. Possible??
I have tried doing =([Re Insp Date])-90 but no dice...
The query is there to query data, not to edit data or manipulate data in anyway. However, I am disgusted by the appearance of the date picker when I pick a field that is a date field.
Is there a way to hide/remove these date pickers from the query sheet?
Within the table itself I turned the "Show date picker" property to "Never" but that didn't make a difference.
Is it possible to select 1 MAX date from multiple date fields for a record?
For example, on an employee record there are 10 date fields, each for a performance review date. Some employees may have date fields 1-3 with values, some with just 1, others 1-5, etc.....depending on how many performance reviews they've had.
Is there a way to pull the MAX review date for an employee, knowing that the MAX date could reside in Field 1 for a certain employee, and could be from Field 7 for another?
Help - Why don’t my date fields sort in date order ?
I’m having a very annoying problem with my date fields. I have a database that keeps records of patients details and their visits to the practioner.
I have a form based on Patients table with name address etc, and a subform based on a Case Details table with details of visits and advice given etc.
I need the Case Details subform to display the latest visit/record at the bottom (the earlier visits at the top of the list). For some reason I just cannot achieve this. Dates seem to be scattered all over and I can’t understand why ??
I have tried sorting the Case Details table in ascending order, sorting the ‘Date of Visit’ field on the form in ascending order (which does work but as soon as the form is closed and re-opened, all the dates are mixed up again).
In the ‘OrderBy’ property of my Case Details Subform, it says:- [Case Details Table].[Date of Action] which according the help I have tried to look at should sort the records ??
I’d really appreciate any pointers as to where I’m going wrong
I have a database with date and time each stored in a separate field. Now I want to query the database based on a start date/time and an end date/time. I started with the code below but it only returns events within the same time range on each day when what I really need is every event from a specified date and time through a specified date and time.
SELECT myTable.ID AS myTable_ID, myDate, myTime, FirstName, LastName FROM Staff INNER JOIN myTable ON Staff.ID = myTable.StaffID WHERE myTable.myDate >= #3/2/2014# AND myTable.myDate <= #3/3/2014# AND myTable.myTime >= #8:00PM# AND myTable.myTime <= #11:00PM# ORDER BY myDate desc
In the above example what I want is every event from 3/2/2014 8:00PM until 3/3/2014 11:00PM. But what I get instead is every event between 8:00PM and 11:00PM on 3/2/2014 and every event between 8:00PM and 11:00PM on 3/3/2014.
