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.

Thanks

Steve

Converting Two Date/time Fields To One Integer

Sep 15, 2006

Hi,

I'm combining two date/time fields in a query to an integer. The first field has the date, the second the time. I'd like the resulting integer to be without the opening 0. How can I do that?

That is, these are the two fields:
2006-09-14 (date/time)
15:00:20 (date/time)

And I'd like those two combined to be 60914150020 (integer) in the third field in the query.

Grateful for advice!

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.

Queries :: Date Field With Time - Query For Date Only And Get All Records

Apr 26, 2013

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.

Subtracting Inside Of A Field? CAN IT BE DONE!!!

Jun 2, 2006

I am looking to subtract number inside the same field. and then return the difference to a new field (column). This data is used to generate a graph and the this is currently done by hand. I know there has to be an
easier way to do this.

Below is an example of what I am looking for.

I have a table called Numbers, and fields or columns called...

Value(s) Result(s)
-70 0
-70 1.02
-68.98 1.09
-67.89 3.11
-71 .71
-69.29 1.52
-67.77

So what I am doing is subtracting row two from row one. The difference is then put in another field(column) in row one. The process repeats, row three from two, four from three, five from four, etc, etc. This occurs for hundreds of rows.

Is there a SQL statement that can do this? Your help is much appreciated!!!

Thanks for your help.

Comparing A Date/Time Field To System Date

Dec 11, 2006

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 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

Validate Field Containing Date AND Time

Apr 24, 2013

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.

Is There A Way To Export Access Date Field Without The Time?

Dec 21, 2007

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.

Inserting A Record With A Date/time Field

Feb 2, 2005

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?

Querying Time Stamped Date Field

Sep 2, 2007

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

Query Of A Date/Time Field With Other Criteria

May 13, 2005

I'm trying to setup a query to pull only the records that have the latest date in Time Scanned for each different serial number.

I have a table with 4 fields: Serial Number, Model Number, Location and Time Scanned. Some records will have the same Serial Number repeated with different Model numbers,locations and times scanned.

I can't figure out how to query only the Last Time Scanned for each different Serial Number. I've tried using "Last" for critria on the time scanned field, but I need that for each different serial number.

It's probably easy...but I'm not able to get it. Thanks!
