Counting Date And Time With Variables

Feb 20, 2007

I am currently running a query which shows a date and time for several products:

Product 1 Product 2 Product 3 Product 4
01/01/07 12:00 01/01/07 15:25 01/01/07 15:25 01/01/07 17:36


From this information I need to count each Product unless the date & time is equal or within 30 minutes.

Any help on this one would be greatly appreciated.

Modules & VBA :: Initializing Date And Time Variables

Jul 1, 2014

I am writing a process for a hospital application in the UK

We have a concept of "Takes" which are periods to which patients coming into hospital are assigned to and thus the consultant (specialist) who looks after them.

They are fixed times between 0800-2000 (Day take) and 2000-0800 (+1) Night take.

I have written the following function to try and determine which take a patient should be assigned to based on the time now to power various queries to enable the end user to quickly see "today's day take" and "yesterday's take"

Testing it I seem to not be able to hit the right "Take times" in my output. I suspect it's a problem with the way I'm initiating my variables as Today 0800 and Today 2000

Code:
Function GetTakeStarttime()
Dim StartTime As Long
Dim EndTime As Long
Dim CurrentTime As Long
Dim YestStartTime As Long

[Code] .....

Hard Code TIME To Selected Date On Form (to Make It Date&time) For My Query Criteria

Aug 17, 2006

Hello buddies :D, do you have any idea how to make this work?

To select data that falls within this criteria of date range between cboDate and cboDate2 (fields on my form). The date in [tblJobDetails]![timeIn] come in this format "08/17/06 10:24 AM", but the cboDate/cboDate2 (takes in date only e.g 08/17/06) what i am after is to evaluate specific hard coded time in addition to the date entered, i.e. even tho, i haven't entered time on the cboDate/cboDate2, I want specific time hard coded where e.g If i select a date range of 08/17/06 and 08/18/06 on my cboDate and cboDate2 it should really be evaluating: 08/17/06 8:00 AM to 08/18/06 8:00 AM.

This is the criteria i curentlly have on my query in design view tha works perfect in selecting date only.
([tblJobDetails]![timeIn]>=[Forms]![frmPendingJobs]![cboDate] Or [tblJobDetails]![timeIn]>=[Forms]![frmPendingJobs]![cboDate] Is Null) And ([tblJobDetails]![timeIn]<=[Forms]![frmPendingJobs]![cboDate2] Or [tblJobDetails]![timeIn]<=[Forms]![frmPendingJobs]![cboDate2] Is Null)
How can I incorporate 8:00am to 8:00am into my cboDate and cboDate2. What can i do to make this happen? Your kindness will be greatly appreciated http://www.naijaryders.com/forums/images/smilies/thankyou.gif

Queries :: Getting Date / Time Range - Date And Time Are Separate Fields

Mar 13, 2014

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.

Modules & VBA :: Dcount With Date Variables

Jul 11, 2015

Im a relative novice with access VBA, and I'm really struggling with using Dcount with date variable. All I want to do is count if a certain date appears in a table. Here is the extract from my code:

Dim WorkoutDate as Date
Dim datecount as integer

datecount = DCount("[WorkOut Date]", "tblworkoutlogs", "[workout date]= " & WorkoutDate)

Whatever dates are in tblworkoutlogs, datecount is still = 0...I've trawled the net and tried many variations of the code but no success!if I change all the date formats to strings in the code and the tables, it works so I know i'm looking in the correct place.

Reports :: Counting Records In Period Of Time

Jun 7, 2013

I've been struggling with getting a report to simply count records (I don't need any detail other than the counts). Here is what I have:

Table CompressorRoundsT contains these fields (many more actually but these are the ones I care about for this purpose):

Date, Shift, Round

Possible records in the shift field are 1st, 2nd, 3rd and the round field has Rnd 1 and Rnd 2.

For each date, I need to count the number of records per shift and per round. For example, the report should show that on June 7th, 1st shift has 14 records for round 1 and 14 records for round 2. Same for 2nd and 3rd shift. I don't need any other details of what the records contain, just the counts.

I've had some success but the layout ends up too spread out because it is including the individual records instead of just showing the counts and it isn't grouping the way I want.

It's a report for management to see how many readings (rounds) were missed in a period of time.

Counting Records For Specified Time Periods In Multiple Rows

Dec 14, 2004

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.

Reports :: Report With Date Select / Search And Other Variables

Sep 26, 2014

I have a report reporting events that occurred today, using =Date() in the query.I want to have a control/box on the report which shows today's date by default, but enables me to select a different date with the outcome that the report refreshes and shows the events on the selected date instead.

Maybe I need a form for this although I would like to do conditional formatting so a report is better.It would also be good to be able to sort by column values, as in a table on a webpage with sort controls in the column headings which work just by clicking.

Reports :: Auto Populate Date And Time Every Time Form Is Updated

Nov 8, 2013

I have a database that stores information for lab testing. Each time a tech does a "step" in the test process he logs it in the table, using an input form. There are different categories, for example preparation, testing, analysis, etc, and each of those steps take time. I have the form autopopulate the date and time with NOW() evertime the form is updated. What i want to do is calculate the time it takes to do each in days. I can easily get how many days it was from now since they logged the test, =NOW()-TestDateTime. What I want to do is get the number of days it took to do each step, ie the number of days between each event. Is there a way to do this?

Counting By Date Ranges

May 19, 2005

I received help on previous threads. Basically, I have built a query to group by course title and then select the number of students that were assigned a course during a specifc time frame. Is there a way to show multiple columns in the query. For example my query now shows, enrollment for March, I would like to column next to it to show enrollment for Feb and then another column for Jan.

This is my current sql view.

PHP Code: SELECT tblContent.Title, Count(*) AS [Students Assigned]
FROM tblProfile INNER JOIN tblContent ON tblProfile.LoginName = tblContent.LoginName
WHERE (((tblProfile.LastName)<>"Demo" And (tblProfile.LastName)<>"Care" And (tblProfile.LastName)<>"Robins") AND ((tblContent.Code) Like "NH*") AND ((tblProfile.Groups) Not Like "*Professional Development Center*" And (tblProfile.Groups)<>"All Users,Professional Development Center") AND ((tblProfile.Delete)<>Yes) AND ((tblContent.Type)="Learning Track"))
GROUP BY tblContent.Title, tblContent.[Date Assigned]
HAVING (((tblContent.[Date Assigned])>=#3/01/2004# And (tblContent.[Date Assigned])<=#3/31/2004#)); 


Thank you in advance for any help you can offer.

Counting Text Box In A Form (by Date Ie Monthly) Help

Aug 3, 2007

Hello there !
I had a few problems yesterday with Dcount in a text box in a form but with your help I cracked it
Below is the function I used
=DCount("[PFP Number]","MAIN Table Do not delete","[PFP Number] = '" & [PFP Number] & "'")

The form is based on a table called Invoice PFPs
The Table contains a list of PFP Numbers (bit like part numbers) there are no duplicates in this table
I also have a "Main Table do not delete" with 26000 claims in it each of which has a PFP Number.
The form has a text box in that matchs the PFP Number in the form with the same PFP Number in the MAIN Table and counts them. his works fine with the above function

What I now need is it to count if the PFP Number matchs only if the date specifyed in the function matchs the claim process date (e.g 01-Dec-06 or 01-Jan-07 etc..) in the Main Table
Hope this makes sense ?

Ignore Time In Date And Time Field

Mar 6, 2007

Hi,

Wonder if someone can help please. I'm quite new to Access so please bear with me.

I have a data field in my database consisting of both a date and time.

I then have a form containing two fields where the user can type a 'To' and 'From' date to extract the records that they are interested in. The query behind this uses the 'Between[Enter The Date] And [Enter The Date]' coding.

The problem is that because the field contains a time it doesn't return any records when I run the query.

Can anyone offer a bit of guidance on how I could ignore the time part of the field perhaps by adapting the above.

Many thanks

Chris

Sort By Time Only In A Date / Time Field

Mar 19, 2014

I have a column/field named [DateTaken] which contains test dates and times in the same cell. I am needing to find those with a test time less than 2:30 pm or <14:30pm.

data looks like this:

8/22/13 4:23 PM
1/29/14 12:21 PM
1/28/14 3:27 PM
8/26/13 4:27 PM

[code]....

this is what I have come up with to extract the time component of data set so that I can then later, sort it by the time in a query.

JustTime: TimeValue([YourField])
JustTime: ("hh:mm",([DateTaken])) and or ("hh:mm",[DateTaken])

I get either invalid operator or invalid syntax errors trying both of these.

Modules & VBA :: Ignore Date Fields In Table When Counting Records?

Jun 6, 2014

Suppose I have a table with a variety of fields; one autonumber, some text fields and some date fields.

I need code to calculate the number of fields that are NOT date fields and then code to count how many of those fields (the ones that are not date fields) have data in them.

Following is the code to count how many fields in a table had data and this works well, but now I need to find a way to ignore the date fields. How can this code be modified to do the same but ignore the date fields?

Code:
Public Function PercentCompleted(Table As String, IDProject As Long, TotalFields As Single) As Double

Dim sampO As DAO.Recordset, iCtr As Long, strSQL As String, Percent As Double
'Takes the fields based on the projectID
strSQL = "SELECT *" & _
"FROM " & Table & " WHERE IDProject = " & IDProject
Set sampO = CurrentDb.OpenRecordset(strSQL)

[code]....
