Queries :: Date Criteria - Query Previous 12 Months Including Months With No Data

Mar 22, 2013

I currently have a form where users can enter an "End Date", click a button, and it queries the data from 12 months prior to "End Date" entered.

Is there a way to force the query to show all 12 months, even if there are no records for a particular month? For example: if the user enters February 2013 in the date field, I would like the query to return:

March 2012
April 2012
May 2012
June 2012
July 2012
August 2012
September 2012
October 2012
November 2012
December 2012
January 2013
February 2013 even if June 2012 has no records, it is included in the query with a value of zero.

This is what I have so far:

WHERE (((Qry_Tbl_Assets.Dte) Between DateAdd("m",-12,[Forms]![Main_screen]![End_Date]) And [Forms]![Main_screen]![End_Date]))

Subtracting Dates, Getting Whole Months

Dec 12, 2005

I found the following code on this site in a search for a method to subtract two dates ie [Startdate] and [EndDate] and display the result as a whole number. ie 2, 6 etc. This code finds the difference but displays the results as 1 year 5 months 2 days, where I need the equivalent as 17.
Can this code be modified to produce the desired result and if so how would I go about it. Thanks for the help.

Option Compare Database
Option Explicit

Public Function getTimeElapsed(StartDate, Optional EndDate As Date) As String
On Error GoTo Err_Handler

If IsNull(StartDate) Then
getTimeElapsed = "No startdate"
Exit Function
End If

Dim YY As Integer
Dim MM As Integer
Dim DD As Long

' use current day if EndDate is not supplied,
' + 1 makes both days inclusive.
EndDate = IIf(EndDate = 0, Date, EndDate) + 1

MM = DateDiff("m", StartDate, EndDate)
DD = DateDiff("d", DateAdd("m", MM, StartDate), EndDate)

' recalculate if DD is negative.
If DD < 0 Then
MM = MM - 1
DD = DateDiff("d", DateAdd("m", MM, StartDate), EndDate)
End If

YY = MM 12 ' integer division.
MM = MM Mod 12 ' remainder.

getTimeElapsed = YY & IIf(YY < 2, " year ", " years ") & _
MM & IIf(MM < 2, " month ", " months ") & _
DD & IIf(DD < 2, " day", " days")
Exit Function

MsgBox Err.Description
Exit Function

End Function

Queries :: Subtracting Date Fields

Jul 10, 2013

I have an Access query which has 2 fields 'Sent Date' and 'Return Date'. Sent date is input by the user when they return an item for repair, return date is input by the user when the item is sent back to us from repair. What I need is a 3rd calculated field which will work out the number of days the item was away for repair. I have included the 3rd column 'Repair Duration' but I don't know how to type the formula in the query to work this out.

Subtracting 12 Hours From A Date-time Field

Nov 13, 2007

I am trying to subtract 12 hours from a time-date field when the payperiod does not equal 01.

in a query I have:

work date: iif([payperiod]="01",[StartTime],[starttime]-#12:00:00#) - Access added a PM before the second hash so it looks like this:

iif([payperiod]="01",[StartTime],[starttime]-#12:00:00 PM#)

When I run the query I get a message box: "syntax error (missing operator) in query expression '00:00:PM#,2))". I am unable to open the query to correct the error. I can cop the unaltered query from a back up database.

My question is how do I subtract the 12 hours.

Adding And Subtracting Dates From Current Date

My first question is how to set a column to be the current date read by the computer.

Example: It will automatically say 5/8/2013 tomorrow without needing updating.

Question 2: How to add a number of days to the current date.


Add 7 days to the current date.

on 5/8/2013 it will read 5/15/2013, then automatically update to 5/16/2013 on 5/9.

Calculating A Date Six Months In Advance Of A Date

Jan 20, 2005

Not sure if this is actually done with a query (hell, im not sure if it can be done) as my Access knowledge is limited but I've got a list of Patient Appointment Dates and I need to calculate a list of 'Next Appointment' dates that are six months on from the appointment dates not including saturdays and sundays (as the health center is closed those days)

BTW this is for coursework, I don't really work for a health center :S

edit: I seem to have put this in the tables forum, not the queries forum. Apologies for that, I'm not an Idiot, Honest!

Date Criteria, Data From Last 6 Months

Jul 1, 2005

Im looking for something that filters information for 6 months prior to any current, non-specific date. Like it will automatically get the data dated from 6 months ago from june, july, or august, without anyone having to go in an change the date criteria.

Below is a non working example of what I am trying to come up with. If I could get something like this, it would save me a ton of time going back and updating all the date criteria for my databases.

Queries :: All Records With 12 Months Of Date?

Aug 6, 2014

We have a field (tbl_Enrolment.CourseCompletedOn) which holds the date a colleague completed a course. I want to bring through all courses completed within 12 months of todays date ( Date() ) from our database. I checked google and it suggested YEAR but that would only bring through dates with the same year, not within a 12 month period.

Subtracting One Query From Another?

Feb 23, 2008

Hi everyone,

I am familiar with databases and basic SQL, but never used Access, so your help is greatly appreciated!

What I *think* I need to do here is take the results from one query, subtract another query from that, then create a table of the results, so that I can make a chart in a report. I say that I *think* I need do that because Iím not confident that this approach is the best but thatís a whole other story...

Please look at the following tables below for an example. The Item table has ItemCode as a primary key. The Bids Table has multiple rows for each ItemCode showing bids for the item:

Item Table
ItemCode Date Address
JH231 2008-Feb-20 123 Test St.
KH831 2008-Feb-21 512 Test St.

Bids Table
ItemCode Amount
JH231 100.00
JH231 60.00
JH421 310.00
KH831 20.00
KH831 40.00
KH831 10.00
KH831 90.00

To make a pretty graph, I would like a table (so a query, or macro, or VBA or something?) that returns the minimum Amount for an ItemCode subtracted from the maximum Amount for an ItemCode based on the example above. What I would end up is something like this:

ItemCode Difference Between Maximum and Minimum
JH321 250
KH831 80.00

I hope this is clear. Any help on how to do this from you Access pros would be great, OR if Iím taking the wrong approach, suggestions on what I should try next. Thanks!!!

Adding X Months To A Date In Criteria Expression

Sep 4, 2006

Hi all,

I need to be able to add x months to a given date which I'm using in a criteria expression. I've figured out that I can just add y number of days, but the answers aren't quite accurate across different ranges of months.

I'm after something like
<[BeginDate] And >([BeginDate]+[3months])

but I haven't turned up anything useful in an hour of googling - finding it difficult to define what I want in search engine terms.

Format Date Yymm Based On Number Of Months.

May 25, 2006

I am importing data to a program that requires the life of an item. This is in months such as 241 months. The valid format for this program is YYMM. 241 = 2001 or 20 years 01 month.

Another example: 16 months should read 0104 or one year 4 months.

Any idea how to convert this to yymm format based on the number of months?

thanks in advance.

Queries :: Date Range Calculation Including Partial Months

Aug 28, 2013

Trying to get a formula or function for calculating profit for each month between selected dates. Partial month calculations are required.

Source Data (record) examples:
Contract1: Startdate = 6/30/12; EndDate = 9/22/12; DailyProfit = $500; MonthlyProfit = $9500
Contract2: Startdate = 7/7/15; EndDate = 12/17/12; DailyProfit = $600; MonthlyProfit = $11400
Contract3: StartDate = 8/1/12; EndDate = 6/30/13; DailyProfit = $350; MonthlyProfit = $6650

User Query #1:
ReportStartDate will always be entered as the first day of the month;
ReportEndDate will always be entered as the last day of the month
The report will always show 6 consecutive months

User selects
ReportStartDate = 7/1/12;
ReportEndDate = 12/31/12

Notable conditions:
-The calculation for Contract 1 will have a partial month profit calculated for September 2012. The other months can show the MonthlyProfit value, with October and December being $0.
-The calculation for Contract 2 will have a partial month profit calculated for July 2012 and December 2012. The other months can show the MonthlyProfit value.
-The calculation for Contract 3 will have no partial months since the StartDate is on a month beginning, and the ReportEndDate is prior to the EndDate. July 2012 will show $0.

Request: I either need a super complicated IIF statement for 6 fixed columns in a query (one column for each month) or a smart function, neither of which I can do.

General :: Populate List Box With Distinct Months From Date Field

Nov 27, 2012

I have a table of data which includes a date field and also various other fields which may or may not be filled with data.I'm trying to populate a listbox with the months for which this data is missing (a separate macro will then loop through these months to fill the missing data) But I only want each distinct month to populate the listbox - not each individual date.

strSQL = "SELECT DISTINCT month([EntryDate]), year([EntryDate]) FROM [SampleTable] WHERE [ValueField] Is Null"
Me.lstSampleListBox.RowSource = strSQL

I want to return the month in <mmm yyyy> format.

Queries :: Subtracting Stock Numbers With A Query

Jan 2, 2015

I'm creating a sales system that allows customers to place orders using a customer account. when a customer completes an order the number items in the order needs to be subtracted from the stock numbers of each of those items stored in the system.

What I have so far is zipped and attached,

The way my system works should be easy enough to understand, there are four linked tables that store information on customers, products and orders. What I'm really struggling to understand is how to take the values in the records in the Invoice-Product table and take them away from the stock numbers for the products in the products table. But only new orders should take away from the stock number when a new order is placed.

If possible I also need to be able to add stock numbers for example if a delivery comes in, and if it's similar enough could that also be done here?
