Modules & VBA :: SQL Date / Time Identifier?

Mar 3, 2015

i am having an issue with sql in vba using a variable for a date time field.

i know you identify date variables with #
i know you identify text variables with '

But now i have a date time field that is set to date but when i run the sql it does not find a match. i have confirmed that both rec and ercd match.

Also, when i change the table to text, i am able to match with single quote but i would like to keep the table as date if i can.

Below is the sql statement in question

isql = "SELECT * FROM Table1 WHERE from = '" & nm & "' AND rec = #" & ercd & "# AND sub = '" & esub & "'"

Tables :: Empty Date Field - Using As Unique Identifier In Index?

Mar 5, 2013

To prevent duplicate records, I use multiple fields indexes, which worked fine until now. I learned that each "empty" fields are consider unique by Access, so not the best in an index to prevent duplicate records. I managed to have it worked using the default value property to give each "empty" records the same value.

Now my problem is that I have a date field which is optional, but I need to use it as a unique identifier in an index. I could again use a default value, but since it has to be a date, I find it confusing. I would rather have a default value of "No date specified" or "-" or even better, "". Unfortunately none of those works with date fields.

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

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] .....

Modules & VBA :: Save NOW (Date And Time) Into Event Log File

Oct 16, 2014

I want to save NOW() (i.e. Date and time) into an event log file. But I just cannot work out the syntax. My insert statement works fine without the date field in, but fails on a syntax error (3134) when I include it.

strsqlac = "INSERT INTO EventLog ( EventTime, User, EventType, EventMessage, DocRef, AutoSeq, CoCode ) " & _
" Values ( '" & Now() & "', '" & GlobUser & _
"', '" & Mess2 & _
"', '" & Mess1 & _
"', '" & Docref & _
"', " & AutoSeq & _
", '" & CoCode & _
"' );"

... it's the first column, EventTime that is the issue. I have tried several different ways of wrapping it in the VALUES () without success.

My database field EventTime is defined as a General date which Access 2007 tells me will give me date and time. That's what I want.

The Value formats I have tried (currently showing as 'NOW()' above, are ...

#NOW()#
#'NOW()'=
'#NOW()#'
and (as I say) 'NOW()'

Modules & VBA :: Date And Time Functions Not Using Current Info

Jun 30, 2014

Encountered a situation where the Date and Time functions in VBA are not using current data? I have VBA code that uses Time to determine certain actions. A new associate took a copy of that code and started tinkering with it to complete a project I assigned. Now, his copy of the code returns old data for the Date and Time functions. It returns 5/27/2014 for Date and 7:15:42 AM for Time. The Now function works properly.

Additionally, running the Date and Time functions in queries works fine. I've compacted and repaired the Access database, I've checked the references, and I've checked to see if he assigned values to variables named Date or Time, but I don't see anything wrong. What am I missing?

Modules & VBA :: Prevent For Duplicate Data (Time / Date)

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 :: Change System Date / Time Without Admin Privileges

Mar 31, 2014

I have an Access 2010 application running on Win 7 Pro which connects to a Back End SQL Server database. I am trying to get Access to synchronise the client pc system date & time with the Sql server date and time. Please note, the date/time does not necessarily have to be correct, it just has to be consistent between the server and all the pcs running the Access application.

I have tried two methods as follows. But both only work if Access with Administrator privileges, which isn't really practical.

Method 1:

Code:
Dim MyDateTime As Date
'Some Code here to get MyDateTime
If MsgBox("Change date & time to:" & vbCrLf & vbCrLf & MyDateTime & "?", vbYesNo, "Change") = vbYes Then
Date = DateValue(MyDateTime)
Time = TimeValue(MyDateTime)
End If

Method 2:

Code:
Private Type SYSTEMTIME
wYear As Integer
wMonth As Integer
wDayOfWeek As Integer
wDay As Integer

[Code] .....

Modules & VBA :: Default Property For Control Bounded To Date / Time Field

Dec 4, 2013

Access 2007

In a table I have 2 fields:

D1 , Date/Time , DefaultValue: Date()
D2 , Date/Time , DefaultValue: Date()+1

In a form (bounded to this table) I have, of course, 2 controls bounded to this fields:

txtD1 and txtD2

If the user change the value in txtD1 (using the Date picker) I like to change the DefaultValue for txtD1 to the new date and the DefaultValue for txtD2 to the new date + 1 day. Something like this:

Code:
Private Sub txtD1_AfterUpdate()
Me.txtD1.DefaultValue = Me.txtD1
Me.txtD2.DefaultValue = Me.txtD1 + 1 day
End Sub

I tried whatever crossed my mind... with the same "result" : #Name?

My Regional settings:

Short date format: dd.MM.yyyy
Date separator: Dot
Simple: 05.12.2013

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?

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 :: Calculating Elapsed Time Within Time Period

Dec 1, 2013

I have a working dB which can calculate a shift duration and sum total all shifts worked within a period for the purpose of producing a labor report for payroll. I have successfully used the DateDiff function and converted the minutes to HH:MM on my form and reports. Now I want to calculate elapsed time for a specific period within a shift, I'll call it OtherHours and I am aiming to calculate a portion of time that meet the following conditions below. I am using field names of [PunchIn] and [PunchOut] and both are of type General Date.

IF [PunchOut] ISNOT Saturday,Sunday
EXIT FUNCTION
ELSE
IF [PunchOut] ISNOT Between Midnight and 0559 hours
EXIT FUNCTION
ELSE
DATEDIFF ("n", <MIDNIGHT>, [PunchOut])

My thoughts are to solve the DateDiff portion and then figure out how to apply the conditions within the IF statements.
