Queries :: Complex Join Based On Date Range

Jul 29, 2013

Context is I have a TABLE 1 that has a record for every package shipped with various details about it, include how it shipped, and the date. Table 2 is a key to go from the ship method to a better grouping we deem service level. Table 3 is a Fuel Surcharge (FSC) Table. It includes various FSC % that vary by different service levels and different date ranges. In the end I need to know the amount of pkgs shipped (by month and servicelevel) and the relevant FSC.I have several tables in my database but we should be able to focus on 3 to explain my situation and only the relevant fields:

TABLE 1 (Main Data):
ShipDate
ShipVia

Table 2:
ShipVia
ServiceLevel
FSCType

Table 3:
FSCType
StartDate
EndDate
FSCPercent

DESIRED RESULT:
Month
ServiceLevel
FSCPercent
PkgCount

Table 1 is Left join on Table 2 based on ShipVia
Table 2 is Left join on Table 3 based on FSCType
The issue is Table 3 is dependent on Table1.ShipDate being between the date ranges as well.

There are overlapping date ranges, however they are differentiated by the FSCType field.The only semi-feasible solution I currently have is to expand Table 3 to include every date, and not date ranges. This will create an issue due to size of date ranges etc.

Print Date Range On A Report Based On A Non-date Field

Aug 7, 2005

Is there a way to show the earliest and latest dates of a report generated by a non-date field?

E.g. I generate a report based on Food, and it'll list the days that this food is associated with. Is there a way to show the first and last day that appears in this report (i.e. the range of dates that the report shows based on the food selected)

Date Range Based On A Record Date

Mar 21, 2007

I am trying to filter out information for an ODBC query I have written, to obviously make it more concise. Because our data is not set up very logically, a lot of my queries are based on text...but that is another story. My current situation starts with a simple make-table query finding certain data within a date range. This is followed up by another simple make-table query to find other specific data within another specified date range. Then I have a cross-tab query between the two tables to locate all the data that shares the same unique identifiers. My problem lies with trying to only pull information from a certain date range. For example, I want information to be included if the data has the same unique identifier as well as falls within +/- 7 days of the received date (dd/mm/yyyy) also listed in one of the tables. Each record will likely have different received dates so I cannot set it as a constant.

Make sense to anyone? I am not confident enough to play around with some expressions...well it is more I haven't been successful at using them correctly.

All help is greatly appreciated.

Thanks,
Jay

Query With Rows Based On Date Range?

May 23, 2005

Hi everyone, I am hoping to learn something new about access today. What I need is to be able to run a query that gives me rows of data based on paramenters that I specify. For example, I will query this all just on one table and I want to come up with an output that is in a nice format as follows:

Parameter..........................Member Count
01/01/04 thru 01/20/04...............298
02/01/04 thru 02/20/04...............287
03/01/04 thru 03/20/04...............301
04/01/04 thru 04/20/04...............254

And so on, usually for a calendar year.

Basically each member has an effective date, like member A might have 01/15/04 effective date and member B might have 01/02/04 effective date. I need to capture the count of members by month based on their effective date range. I would like to do it all in one query like above instead of just running a query for January, then February, then March, so on.

Is there a way to do this? Right now I am just running a query and getting one member count at a time and copying that number to an excel spreadsheet. it works okay, but is time consuming. I would rather semi-automate things for me. Any ideas?

Oh and I am new to access, by no means an expert, so be gentle with me.

Thanks,
Hanna

Create Multiple Records Based On Date Range

Jun 28, 2006

I have developed a Debt Management program for work but I am stuck on a feature that we need to add to it. Basically I have a table which holds "planned future transactions". These are ad hoc transactions that need to be added from time to time to the clients budget. For example the client might have $500 a quarter for school fees for the next two years or he might receive a bonus every six months for the next 5 years. Currently we are putting these in manually but it is tedious and is causing complaints. The feature I require is to be able to add a record such as the school fees, nominate that this fee is paid every three months for the next 8 quarters and get the system, say through an append query? to create 8 records, each with the appropriate date 3 months after the previous one.

Any suggestions or assistance would be appreciated.

Thankyou

Queries :: Derive Date Range Based On Expression

I have a query that I want to "filter" based on a date derived from a Build statement (Expression). The Build statement works I can even sort by "Ascending".. But when I try to add a "Between [Startdate] And [Enddate] statement in the Criteria box, returns nothing".

Queries :: Specific Date Range Based Off Of Other Data

Jun 14, 2013

I have multiple buildings that I own. Each building earns a monetary amount each day. Some days they earn $0, some days they earn $1,000. This is all kept track in a data base in which someone manually enters the information each day.The three fields are:

Building
Date
Profit

I have narrowed a query down to one building, and I am interested in two things. How do I write a query that shows a 30 day peak (the most profitable 30 days). In other words. I want to see the following
Building: GNB Tower Date: 02/14/13 - 03/15/13 Profit: $25,162

The next thing I am interested in is a 7 day peak from within these 30 days. This shouldn't be too difficult if I can figure out how to query these 30 days, I can query 7 days out of those 30 days. So this bigger mind stumper is the first one.

out of a date range of months and months (Let's say 10/12/13 - 6-14-13).Once I figure this part out, I am sure I can figure out how to compile all buildings into one large report with their 7 day peak and 30 day peak.

Get Some Values And The Inmediatly Previous Ones Based On A Date Whithin A Range...

Jan 28, 2008

Hi everybody!

First of all, I didn't know how to search for the precise info regarding my question, so, If it is repeated, feel free to close this thread or delete it.

So, here it is my question:

I have a table with values taken once monthly, that is, for each person on that table, I would have a maximun 12 records per year. In that table I have the Id of the person, the date field where I store a date when I get the record, a field where I store a value and a control number field. The values on the control number field go from 1 to 20 (or less).

What I want to achieve is, given a range of dates, show the last two controls of every person, something like:
id, last control date, last control number, value of last control, previous control date, previous control number, value of previous control.
As you could see, I want to show in the same row the last two controls for each person, only if the happend to have two controls, if they have only one, it wouldn't be necessary to show them, so, how can I do this?.

Thanks in advance! :).

Forms :: Calculating Working Days Based On Date Range

Mar 20, 2014

I am trying to calculate the working days Based on all web searches I am unable to find the specific scenario I am working in Auto industry, which means auto industry usually close twice a year for any reasons, let say in July for one or sometime two weeks and in December depends upon the Christmas date usually from December 20 till Jan 01

Now my question is when i am enter the holiday details in table do I have to enter line by line date e.g. july 01, 02, 03 (I am able to understand, how this works but still not yet tried) OR july 01 to July 07 (which make sense, but unable to find how to use date range to calculate working days)...

Modules & VBA :: Exporting Multiple Queries Based On Date Range

Aug 29, 2013

I have recently set up a button that exports multiple queries to one Excel file, using TransferSpreadsheet code. This works great and saves a lot of time, the only thing is on many of the queries I have a date range set, so you have to enter a date range to get the results.

Is there away that once I press the button I enter the date range once and than it exports the rest of the data based on this range, rather than entering the same dates multiple times.

Modules & VBA :: Filter Subform In A Form Based On Date Range

Jul 26, 2015

So I have a search form that I created that has also a subform (a continous form, that has a query as its source) where my records are listed. I started on making a Between dates filter where i would be able to pick dates and get the results of records that are in that range.

I put two text boxes in which I set format to Short Date so that I get the button to select the date from a calendar for each text box. Then I made a button that is only for this and added a Clickon code so that it filters my subform over the recordsource of the form. The problem is is that i get an error and it doesn't filter.

Code:

Private Sub btnDatumUpis_Click()
Dim SQL As String
SQL = "SELECT qrySearchV.VID, qrySearchV.MarkVoz, qrySearchV.ModelVoz, " _
& "qrySearchV.TipMot, qrySearchV.Regist, qrySearchV.VlaVoz, " _
& "qrySearchV.KorVoz, qrySearchV.KatV, qrySearchV.DatumUVoz, " _

General :: Auto Generate Entries Based On Date Range

May 16, 2013

I am looking to have entries made to the table based on a date range. I have a database of events and most repeat daily, weekly, etc. When I enter them into Access, they go in as a single entry with a start and end date. But I need to have them as individual entries for each day so that rather than one entry of 5 days, I need to create 5 entries of one day each.

Queries :: Attributing Week To Date / Time Based On Specific Range

Aug 21, 2013

I have a weekly list of transactions that come in the format DD/MM/YYYY HH:MM:SS, I need to tag these individual transactions with a week number. The problem is, I can't use the Datepart function etc. as the day is classed as running from 8am to 8am rather than midnight. I have a list of all of the weekly date ranges for a few years (with the time) so I was able to solve this problem in excel by using the Index and Match functions. However, I'm trying to automate this process as much as possible so I'd rather perform this function in Access.

General :: Timesheet Manager - Report Based On Date Range Given By User

Jul 7, 2014

I have the following project that works as a timesheet manager:

Users enter in a form the employee name/date/hours worked/role/overtime (yes or no)/rate... on a daily basis. At the end of every week, they must create a report depending on the dates given in a query.

I have only one table (tbl_EmployeeHours) and a query to calculate the number of hours between two dates.

At the moment a report gives me all the information above (employee name/date hours worked etc..) but what I am trying to is a bit different.

I need Access to create a report (based on a date range given by the user) that would give me: per unique name, the number of normal hours worked in total, next column, the number of hours worked as overtime (rate 1.5), then, the number of hours worked as overtime (rate 2).

This means there are 3 different totals. For example, in the date range given, someone might appear twice but in the report he will appear only once with 3 different totals...

My guess:

I would say I need to create a different query for the 3 different totals (normal hours, overtime 1.5 and overtime 2). For each query you would need to ask the user to input the date range (which would not be so user-friendly I agree...). Then, I am not sure how access would create that list of names and combine the 3 different results from the queries...?

Modules & VBA :: Create Multiple Records Based On Date Range - Button Click Event

Jul 31, 2014

I work for a company that manufactures home appliances & electronics. When those products fail within the warranty period, we are obligated to repair the units for the customers.

We have around 200 factory technicians who make those repairs. Each tech is able to make approximately 8 repairs each day. We have a dispatching system that assigns the repairs to the techs based on their availability each day. But the problem is that we have to manually enter and adjust the schedule for all 200 techs every single day, and this takes a lot of time. And of course technicians get sick, take vacation, etc, so we have to adjust the schedule so no techs will be assigned calls when they're off.

The problem: For example, currently when a technician takes off for 2 weeks, the user has to enter 14 individual records for the tech, which is somewhat time consuming. What I need is to program a button click event to determine the two dates (startDate & endDate) and append multiple records from one single entry in the form for each date in between and including the two date fields.

I know I'll probably need to create a loop that will loop through the two dates on the form and append a record for each day, so I can then cross reference the dates to the master schedule dates to make sure that no availability is opened for the techs taking time off.

Queries :: Show Data - Query Based On User Selected Time And Date Range

May 17, 2013

I have a form that request information from the user (StartDate, StartTime, EndDate and EndTime) the problem is that it's not working. The only way I can get any data to show is when I remove the StartTime and EndTime. Only then will it pull the items from the StartDate and EndDate.

Here is what I have as my criteria: Between [Forms]![OpPROD_ALL]![StartTime] And [Forms]![ OpPROD_ALL]![EndTime] And Between [Forms]![ OpPROD_ALL]![StartDate] And [Forms]![ OpPROD_ALL]![EndDate]

The users will be able to request a report based on a start and end date along with a start time and end time.

Side note: this is to pull date for 3rd shift (Example) 4/14/2013 10:00PM - 4/15/2013 10PM

Modules & VBA :: How To Do A Join Range Query

Dec 9, 2013

I am currently trying to do a range join query in access (not an expert at all with it) but I realized that it's not easy. It probably needs a VBA code but still not sure how to do it. I basically have a column with number of days e.g

Number of days
18
1
0
56
8
-19
369

Eventually I would like to do a range join query (similar to excel range vlookup) with the following table

NumberofDaysWeeks
0 Same Day
1 1 Week
7 1 Week +
14 2 Week +
21 3 Week +
30 1 Month +
60 2 Month +
90 3 Month +
120 4 Month +
150 5 Month +
180 6 Month +
210 7 Month +
240 8 Month +
270 9 Month +
300 10 Month +
330 11 Month +
360 12 Month +

After joining the two tables with an approximate range (as in excel) the final table should look like below

Number of days Weeks
18 2 Week +
1 1 Week
0 Same Day
56 1 Month +
8 1 Week +
-19
369 12 Month +

Note that value -19 is an error so it should not return anything however i still want to see the value in the final table.

MS Access "Joins", Possible To Join Via A Range Or Add Code?

Nov 2, 2007

hi im pretty new to this, using access2000 i believe


i have a large amount of data and have been able to join them successfully. using the "left" "Operator" "right"


one of the things id like to join are dates, but the dates i want to join are not exactly equal to each other so i cant just use a operator "=".


i need to be able to tell access to link the dates within say 30 days of each other.



Ideally something like “left” “>” “right” -30


currently im using excel to do this for me but if access can do it then it would be great.


in excel i use a macro which matches dates within 30 days, and just use a simple

If range("A1") < range("A2") + 30 and range("A1") > range("A2") - 30 then ...........




so is it possible to have access join things within a range?


would be grateful for any help ;)
