Work Periods
Nov 1, 2007
HI All
I have a question that I just cant seem to get my head around....so I thought I'd pick your brains!
I have a table that has DriverID, Date, Work, Sleep, Rest. As you can imagine, this records their hours of work, sleep & rest.
Now with new fatigue management laws in Oz, we need to find out if they're working for more than 168 hours in a 14 day period.....
My thoughts are, create a query that runs through every date of the year, then counts forward 2 weeks, sums the WORK hours and only displays anything over 168 hours??? Is this correct? Would that not simply die ? Considering we have about 30 drivers to run through?

I have read more post than i care to think about but I can't stil get my head round the following problem.
I have created a database (with this forums help) but I am stuck on the following query/form/vba etc....
Our staff holidays run from 01/05/05 until 30/04/06 and i have a query that calculates what holiday entitlement staff are due from 01/05/05 on a daily basis up to 23 days worth of hols ending on 30/04/06, but I can't work out how to set next years holiday period 01/05/06 - 30/04/07 without changing the form manually, is there a way for it to auto update??

Hi all!
I want to add a function to a form that filters records from a specific date period.
Each record has a field containing the date the record was added.
Example: I want to show the records added between 15.09.2006 and 10.10.2006.
Furthermore, the “from” and “to date” must be defined in textboxes, and the filter initiated with a button.
I need this functionality on a continuous form and in a report. How do I achieve this?

I have several pieces of equipment that register data every minute, is there a way to do like a 5 minute average
i.e., 00:00 - 00:04, 05:00 - 09:00
NOT 00:00- 05:00, 01:00- 06:00 and so on.

We have a db of salmon survey data where catch data is recorded by date, site, etc.
Historically, we have used ‘sampling periods’ to group our results into blocks of time that can be compared from year to year, and within year.
Now, having frequented this forum I’ve read that we shouldn’t store information in tables that can be calculated from fields and I want to try to follow that advice in this instance but am having trouble working this out.
Here’s how we define a sampling period.
1.The start date of the first sampling period in a sampling year is the last Monday in the most recent November.
2.Each sampling period is 14 days long.
What I want to do is have a query use the date of a set to calculate what sampling period the set belongs to. I have an idea that I could use a datediff function to calculate this if I can figure out the ‘last Monday in the previous November’ part. I’ve searched this forum and googled but am having trouble finding anything that I can adapt to this as a query expression.
Anyone care to help a fish bio out? Much obliged :)

I am new to Access and would be very grateful for some adivce on setting up a query.
The data in the table below comes from a photon counter. Both fields are numbers although TIME actually represents seconds.
I need to be able to group the DATA field by arbitrary TIME periods. e.g. to divide the table up into bins of, say, 8.7 seconds length, showing the total accumulated in the DATA field for each successive period of 8.7 seconds.
The tables are about 300,000 records long.
Any help would be much appreciated.
Thanks,
TIME - DATA

285748175.894557 - 100

I have some issues with summarizing in a query. My intention is to summarize income and expenses over periods
This is how it should look like.
Periods_____Total income___Total expenses
01-2013_____234__________435
02-2013_____533__________132
03-2013_____345__________853
etc
I made the following query to get the result I wanted.
Unfortunately, the result seems to be multiplied instead of summarized.

Hello,
I'm having a hard time trying to figure out how I should go about designing the table structure for the hours tracking for the database I'm working on. Basically, I have a table with projects (tblProj) that I need to track the number of labor hours worked per month. The problem lies in the fact that each project could have varying time periods, anywhere from less than a year to more than a year and can start and end at any time of the year.
I was thinking of creating a second table (tblProjHours) to store the hours for the project but I'm not sure what the most efficient way of doing this would be. My idea was to create a table as follows:
tblProjHours
ProjHoursID (pk)
ProjID (fk)
BeginDate
EndDate
Month1
Month2
Month3, etc....
I would create a large number of fields/columns, something like Month1 to Month36 just to make sure I have enough months to enter in the hours. This is of course inefficient since some projects would be way shorter than the maximum allowed months set by the table structure and there is always the possibility of surpassing the maximum allowed months based on the table structure. I was wondering if someone had any better ideas on how I should pursue the design. Thanks in advance!

I'm having trouble finding an entry anywhere about this, although I'm sure I'm not the first person to come across it...
When I am typing my entry into a combobox it begins to autosearch, highlighting the part of the entry that it finds that matches the beginning that I typed in (as a normal combobox does in access).
However, when the entry it finds has multiple periods in it (i.e.: S.T.A.R) it stops searching and does not highlight the remainder of the entry it moved to. I'm not sure that searching is the correct term, which may be why I can't find any information on this, but is there a way to correct this problem?

I have a MS Access database that tracks when packages are received, returned, etc from different agencies. I need to create a query or report that shows how many packages were received, returned, etc PER MONTH, PER AGENCY. I was able to create a query that listed all the "Date Pkg Rec'd" dates for October (Between #10/1/2004# and #10/31/2004#), but I don't want a listing of all of the dates, rather a total of the records within those timeframes PER AGENCY. For example, APHIS 10, FAS 3, etc.
The other problem I have is I need this done across many columns without excluding those records without an October date (for example) in them. For example, I could have a "Date Pkg Rec'd" date in October, but not an October date listed in the "Date Pkg Returned" column.
Basically, I need the simpliest way to generate monthly "record totals" for several fields.
Any help would be appreciated.
Thanks.

I have a grouped query that returns a list of all periods qryPeriod
Code:
SELECT [tblMaster].Year, [tblMaster].Week, ([Year] & " - " & Right(0 & [Week],2)) AS Period
FROM [tblMaster]
GROUP BY [tblMaster].Year, [tblMaster].Week, ([Year] & " - " & Right(0 & [Week],2));
Year | Week | Period
2013 | 48 | 2013 - 48
2013 | 49 | 2013 - 49
2013 | 50 | 2013 - 50
2013 | 51 | 2013 - 51
2013 | 52 | 2013 - 52
2014 | 1 | 2014 - 01
2014 | 2 | 2014 - 02
2014 | 3 | 2014 - 03
2014 | 4 | 2014 - 04
[code]...
these are then used as the start of a between lookup against [tblMaster] along with the last record in the qryPeriod (2014 - 04)...I will need 4 queries so If someone can sort out last period - 8 I can probably do the others.would DLookUp do this say return the last 4 values, Last 6 Values and Last 8 Values

Suppose that you want to make a formula which will calculate time periods based on a given tariff. To be more precise.
Suppose you can "get in" somewhere, entrance is $2.
You are free to stay there, without additional charge, for 5 days.
Then, for the next 5 days, the charge is $1 per day
The next 7 days, the charge is $1.5 per day
Thereafter, $3 per day.
In this scenario, we can make a query, we use datediff function to see the number of days between "gate in" and "gate out".
The problem is that the tariff is not very simple and the query gets to big and difficult to control with lot's of "iif" and may be I need to make more than 4 queries and union select and so on.
I tried to find in the docmd if there is any suitable function that I could use.

I developed a finance tracker database for tracking project revenues and costs (forecast and actual amounts). I have a form where we enter a new Work Order in the DB. This Work Order form has a continous subform where we create all the billing periods needed for the life of the Work Order. Once the billing periods are created (opened) we can then add our revenue and cost forecasts for each period. We have a Billing Period lookup table that has our billing periods with their respective start and end dates (which usually begin around the last week of a month and end about 3 weeks into the next month).
For the purpose of this question, lets say we only enter the required WO_Number and WBS_Code (Composite key) and the Work Order Start_Date and End_Date. I want to click a button to runs some code to automatically create all the billing periods for which their start and end dates fall into the Work Order start and end dates.
For example, say a Work Order starts on 5/1/2013 and ends on 7/31/2013
The billing period dates in the Billing Periods lookup table are as follows:
May-13 ---> 4/22/2013 - 5/19/2013
Jun-13 ---> 5/20/2013 - 6/23/2013
Jul-13 ---> 6/24/2013 - 7/21/2013
Aug-13 ---> 7/22/2013 - 8/18/2013
Then we would need the following billing periods created in the Work Order subform:
May-13
Jun-13
Jul-13
Aug-13
I don't even know where to start on this. Is it possible to automate this process with the setup I have? If so, how would I structure the VBA code/logic to use the billing period lookup table and create entries in the subform for all the billing periods that fall into the duration of the Work Order.
The attached DB is a stripped down version with only the tables and forms needed for this problem.

We are creating a simple database to maintain driver license information for faculty, staff, and students who use cars from the university’s motor pool.
To do this, I have created two tables: tblDRIVER and tblLICENSE.
The fields in tblDRIVER are:
pkfDriverIndex
strLastName
strFirstName
strInitial
strAddress1
strAddress2
strCity
strState
strZIP
datBirthDate
The fields in tblLICENSE are:
pkfUpdateIndex
fkfDriverIndex
datDateUpdated
strState
strLicNumber
datExpirationDate
ynViolations
ynActive
Information about the driver is stored in tblDRIVER and the driver’s license information is stored in tblLICENSE. Periodically, we run a report that identifies drivers whose licenses are due to expire within a certain number of days. All this works fine.
My problem is that I am trying to create a lookup form that will load from a data entry form that will permit the Motor Pool Clerk to look up a driver by name and review the licensing information (which appears as a subform).
All this sort of works- I am using a combo box (based on a query) to look up a driver’s last name (which it does) and to populate all the driver’s information on the look-up form (including license information in a subform). Currently, the combo box locates the driver (including the unique index, last, and first names), and populates the form with first and last name but the rest of the information is not displayed on the look up form. Worse still, sometimes one driver’s last name matches up with the first name of the next driver listed in the table! This seems to happen only if a look up is attempted more than once. What gives.
Thanks for the help.

I’m a newbie to Access, I have done some simple things but I now have to do something that is out of my league.
I work in an engineering company and I'm trying to make a database that the engineers can select a specification quickly, a specification or spec is like a table. Things like materials, ratings, pipe Schedule, etc are stored in it. The spec says how strong a pipe will be.
When selecting a spec you have to look at the service (what the pipe is caring, eg high pressure steam, or low pressure water). Services also store things like Design Temperature and Design Pressure.
You are giving the Service, and you have to select a spec that will be able to handle the Design pressures. To do this you compare the Design pressure to the Maximum allowable Pipe pressure (it is calculated at the join (flange) as this is the weakest point).
One other pike of information is the Tables that have the Maximum allowable Pressure. To find the Maximum allowable Pressure, you need to know the Material, Rating and the Design Temperature. Each material has its own table.
If you have a look at the attached file then in tables, SPec has Spec ID (Spec) which is Primary Key. Flange Material (FlangeMat) and Flange Rating (FlangeRating).
The Flange Material should take you to another table, FlangeMat. This table is used to get you to the correct Maximum allowable Pressure table.
There are 2 Maximum allowable Pressure Tables, TABLE_211 and TABLE 212. Here the rest of the information from the Spec is needed (Flange Rating (these are the field names with 150, 300, 1500, etc numbers)). And also the Design Temperature is needed of the service.
Then it looks up the Maximum allowable Pressure from the Table and displays it. I was thinking a form.
Also the design Pressure needs to be displayed so the engineer can compare the two.
So for the form, there will need to be a drop down that has the Service, A drop down that has the Spec, and the two values, the Design Pressure and the Maximum allowable pressure.
All I have done is shown on the file, I started to play around with the Relationships and tried to create a Form but I could not get it to work so. I deleted it and left it with just the tables. If possible can someone please help me, maybe even get my file to work and the post the working one, I will then be able to understand it.

The company I work for uses A97 throughout. Although on my laptop I have Access 2003. I want to design my inventory control database using A2003 not 97 for obvious reasons. I know A97 users cannot open a Acess 2003 db.My Q is: If I created a A2003 db and also built some data access pages within the database and placed it on my server, could users view/add/edit records in the db via these pages using their web browsers? This would only be required across our small network of less than 10 users.Any advise welcome. Even just a YES or NO would help Many thanks.

Hi All,
I need to create some conditional formatting on a field that will change the colour depending on how much money has been spent
I have MaxBilling As the Field I want to attach the condition formatting too which can be a user entered value or system updated depending on other things.
The Current worked costs total field Is Called Text119.
when a project starts The Cost will be 0 so I don't intend to assign a colour there.
when the Costs get to 50% of MaxBilling I would like to change the colour to Green
70% Chances to yellow
90% Would change to Dark Red
I can do most things but %'s and me don't mix well LOL
Any help would be much appreciated
thanks

I have two database which are very similar. They both use the same back end table. I have a query that I developed in one db and it works correctly there. However, when I import it into the other db, I get the Ambiguous Outer Joins message. I've tried copying the SQL from one and pasting it into the other and that didn't help. I've checked the table used and they are all properly linked in the second db. Any ideas about what could be going on?

I have created a query thats initiated by a command button from a form and one of the criteria for the query is a 'Like' command.
On the form, various option buttons and combi-boxes determine the search criteria and put it into a hidden textbox. Then, the query is run based on the contents of that hidden textbox using 'Like'.
However, I cant seem to get the 'Like' command to work with the contents of the hidden [forms]![frmSearch].[txtSearchcriteria] field.
Do I need to edit the VB code on the form to format the text to include the Like '* prefix and *' suffix, or should my search box remain basic text and have the Like command in the query ??
I seem to have tried loads of variations incorporating the various components of the Like command (the asterisks, single quote marks and even the Like command itself) on either the Form field or query but nothing seems to work. Anyone have any ideas ??
Thanks chaps.

The on click event, for a Report, has the following:
Sub DateEntry()
Dim Start_Date As Date
Dim End_Date As Date
Start_Date = InputBox("Enter Start Date mm/dd/yyyy")
End_Date = InputBox("Enter End Date mm/dd/yyyy")
End Sub
This works fine and allows for Input. I added the sub below, but it does not work and the report opens:
Sub CheckEntry()
If Start_Date Is Null Then
MsgBox "No Date was Entered"
DoCmd.Close acReport, "Summary Action Report"
Exit Sub
End If
If End_Date Is Null Then
MsgBox "No Date was Entered"
DoCmd.Close acReport, "Summary Action Report"
End If
End Sub
