I Would Like To Blank A Date / Time Field
Oct 24, 2005
Greetings,
I am running some code to work on a table and I want to blank a date field. It is a stock control system where when a vessel is emptied I would like the updated field to become blank as it is empty and therefore has no history (this is stored in another table.)
The code I have tried to us is; (where updated is a date/time field)
Else
rst![Updated] = " "
rst![Volume] = "0"
End If
rst.Update
rst.Close
The message I am getting is 'Data type conversion error'.
How do I get this field to be blank by code?
Thanks in advance

I have a date/time text field on a form with the General Date format and a combo box next to it that has sequencial times as the row source (IE. 12:45 AM, 1:00 AM, 1:15 AM, 1:30 AM, ETC.) When the user chooses a time in the combo box, I want the time portion of the text box to be updated with the chosen time in the combo. I have tried a few things but cant seem to get it right.

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

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.

I want to update an MS Access table date field with a blank date. How do I go about it? Right now, if the "dateAskFor_Funds" text field is blank, and I try to update the "AskFor_Funds_Date" field in the database, I get an error. That is why I don't do anything.
What expression should I use in the place of
intJunk = 1
in the code caption below.
Private Sub cmdUpdateApplication_Click()
Dim todaysDate
Dim intJunk As Integer
Dim rst As ADODB.Recordset
todaysDate = Date ' MyDate contains the current system date.
Set rst = New ADODB.Recordset
rst.Open "EA_Apps_List", CurrentProject.Connection, adOpenKeyset, adLockOptimistic
…
…
…
If IsNull(Me!dateAskFor_Funds) Or Me!dateAskFor_Funds = "" Then
intJunk = 1
Else
rst!AskFor_Funds_Date = Format(Me!dateAskFor_Funds, "Short Date")
End If
…
…
…
Set rst = Nothing
End Sub

Hello.
I have a query that is pulling data based on a date in a table. For some records, that date field is empty. For those records, the data should be pulled based on the date of 1/1/06. I tried doing this
=IIf([Signed SLA Received] Is Null,1/1/06,>=[Signed SLA Received])
It doesn't like this at all, it brings back no data. I also tried putting 1/1/06 in quotes, but it didn't make any difference.
This is probably a totally incorrect way to get this done, but I don't know how else to try it.
Thanks!
Stacey

Access 2010
One of the Field Names in my table is titled ActionDeadlineDate, with Date/Time selected as the Data Type for the field. On one of my forms I have created a text box based on this field. Under Properties/Control Source for this text box I have inserted the following formula:
=[DateReceivedinADR]+40 Basically, this forces the text box to auto populate to a date 40 days beyond whatever date is entered in the DateReceivedinADR text box. On the form itself everything works flawlessly.
I have created a query that includes the ActionDeadlineDate field. However, when I run a report off this query it will not populate the date for this field. On the report this column is just blank, with no date indicated.
All other date fields I use on the form (at least those without an underlying date formula) appear as they should. Is there a way to make a date based on a formula appear on the report as well?
Hope I didn't make this too complicated. Maybe what I am asking for is not possible since a date formula is being utilized in the text box, rather than a simple date.

I am building a database for a client who manufactures car parts. I have a table to store vehicle model. Each model has a date range of production. I have two build dates from and to. Both of these fields are setup as date fields on the table. I made both fields required with a mask for validation. In the "build date to" field if a car is still in production I need to leave the field blank. Is there any special character that will allow me to store a required field blank.

I have a query based on a table which has a date field. the field both in the table and the query have the time also in the date value so when I try to query on a date I get nothing if I copy the date and time from the field I will get the result for that record if I just use the date I get nothing. I have tried the format which does display just date but if you click on the field the time is also there You must be able to query for a date only and get all the records.

Hi,
I am trying to compare a value in my databse produced by the date() function, short date format, to one that is exactly 24 hours after the value recorded by the date() function. If the value in the database is 24 hours prior to the current date(), I need to flag a text box a diffrent color to alert the user. I am unsure on the If statement that I will need to produce this result.
Any help would be greatly appreciated!!!!
Thanks

I have a single table with customer information, one of the fields is a date field "LastContacted".
I'm creating a search form with 2 date fields (txtDate1 & txtDate2) to search a date range of the LastContacted field, and I need to write this into the query that the search form uses.
I have written this using Nz so that it can still return results if the search boxes are left blank:
Between Nz([Forms]![frm_AdvancedSearch]![txtDate1],#01/01/1989#) And Nz([Forms]![frm_AdvancedSearch]![txtDate2],#01/01/2999#)
This seems to work and it returns lines from the table where there is a date entered. However some of the fields in the table have no entry in the LastContacted field. How to code this query so that it also returns lines where the LastContacted field is blank in the table?
I have tried:
like "*" & (Between Nz([Forms]![frm_AdvancedSearch]![txtDate1],#01/01/1989#) And Nz([Forms]![frm_AdvancedSearch]![txtDate2],#01/01/2999#)) & "*"
but this returns errors when I try to run it.
I'm using Access 2010.

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

I have a form with date/time field. I have the default value at =Now(). My problem is I would like for this particular field to stay with the current date/time all the time. I mean if I created a form last week with the date/time of 3/14/2005 12:54:34 PM and go back to the same form to edit something this week I would like for that particular date/time to be the current date/time and not the date/time from the week and time the original form was created.
Thanks for any help!

I have a field that contains an input mask : 99/99/00 99:00;0;_ this allows the user to enter a date and time in one field. Such as 04/24/13 15:00 . I want to put validation on that field, so that the user can't enter a time that does not exist such as "25:30" or a date that hasn't happened yet. How to accomplish that? The data is going into a linked SQL table so I'm limited on what I can do on the table end I think.

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.

Right now to get my Access database into MySQl I have to copy it out of Access into Excel then I export it to a delimited text file.
I would like to eliminate the Excel part and go directly from Access to a text file.
The problem is with the date fields. When exporting from Access it always adds the time (00:00:00) which MySQL chokes on. It seems there should be a way to do this with the export function, so that the date is just the date and no time.
Any help would be appreciated.

Hi,
I'm trying to insert a record into an Access database from some ASP Code.
I have:
...
strSQL = "INSERT INTO tblUser (UserID, Date, Comments) VALUES " & _
(" & nID & ", #" & Now() & "#, " & "''" & strComments & "');"
conn.Execute(strSQL)
...
I'd have thought this should work but it doesn't.I just get a "Syntax error in INSERT INTO statement".
My date field, called "Date" (just in case that's a problem!) in my database has no input mask defined, it's just a basic date/time field. I've tried replacing the '#' symbols with single quotes, and doesn't work either. I haven't had any luck finding a definitive example of how to do this, even though it's trivial surely. All the similar examples I've found talk about how to update a record set with a date, or how to set the system locale, etc.
Any ideas as to what I might be doing wrong?

Hi,
I use a query to return values between two dates, here's the code I use:
Between [Select Start Date:] And [Select End Date:]
However because my dates are time stamped (they need to be!) the query omits anything on the end date, for example:
Between [01/09/2007] And [05/09/2007] will return values for the 1st, 2nd, 3rd, 4th but not the 5th - because (I think I'm right in thinking this but I might not be!) it only returns values upto midnight on the 4th? so 05/09/2007 13.42pm won't show up because it's after 11.59 on the 4th.
I can't ask people to enter in an extra day because quite alot of people who use our database won't remember and it'll cause alot of problems when they forget and get the wrong figures.
I've tried adding the following:
" & "11:59:59""
onto the code but Access says the expression is typed wrong or is too complicated to be evaluated.
Does anyone know how to fix this code please??
thank you for your time

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.
Thanks
