Criteria For Empty Fields (date/time)

Aug 10, 2005

I am creating a query with criteria for a dates column. The column cotaining dates in my Table has many empty fields. I want to limit the criteria for my dates to >#1/1/2004#, but I don't want Access to exclude all the empty fields because I want all the data displayed for the purposes of my report.

What do I do? I'm not terribly familiar with Access, so please explain as completely as possible. Thanks in advance!

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.

Date/Time Criteria- Simple, Right???

Sep 13, 2006

OK... what am I forgetting?

I have a linked SQL table with a Date/Time field called DATE. ALL I WANT TO DO is pluck all the records with a single date from that table.

Predictibly, the date field has values like this:
9/11/2006 12:40:46 PM

If in the MS-Access query I use criteria of #9/11/2006# I get other dates also. I have tried variations on Date() or DatePart but those either fail or don't work. Sheesh.

ULTIMATELY, I want to restrict records to a specific date, and then a certain hour of that date, so if you can include this bit of additional logic in your response, that'd be great too. Note: I am trying to structure a query, not write code.

Thanks!

Date And Time Problem With Criteria

Jan 9, 2008

Hello, I am having a little trouble trying to get a criteria to work with a query in a database that someone else has passed to me.

In an InputTable there is in a field called DateIn with properties of date and time (general date). I want to be able to create a report that will allow the user to just chose to run the query for one day. Eg. Run the query using a dateinput of 2/01/2008. It just returns all of the records and ignores the criteria. I do not normally have this problem and was wondering where I should be looking.

SELECT InputTable.OrderNo, InputTable.[Customer Name], InputTable.Postcode, InputTable.ReturnsRef, InputTable.Description, InputTable.Unwanted, InputTable.POReturn, InputTable.Faullty, InputTable.Damaged, InputTable.Mispicked, InputTable.Replacement, InputTable.ItemRefund, InputTable.PostageRefund, InputTable.QReason, InputTable.QResolution, InputTable.DateIn, InputTable.Type
FROM InputTable WHERE (((InputTable.DateIn)=#1/2/2008#)
Many thanks in anticipation.

Date/time Period Criteria Confusion

Jan 30, 2008

Hi there

I have created a database in Access XP (2002). In a nutshell, the database records numbers of people attending a seminar; which can take place any number of times per week, and so hence can take place any number of times per month.

I have set up the query so that it can run immediately after a seminar to show the attendants who attended the seminar on that current date "Date()" in the criteria box. However, how would I go about setting it up so that it shows who attended every seminar in the current week or month?

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!

Date / Time With A Wild Card As Criteria In Query?

Apr 21, 2015

How may I write a criteria in the query where I can pull records with date/time data type (01/31/15 1:30:23 PM) based on today's date?

Example using today's date (4/21/15):

Date()= 4/21/15

The query will pull these records:
ABC 4/21/15 9:14:40 AM
DEF 4/21/15 10:50:02 AM
GHI 4/21/15 2:32:35 PM
etc.

The time does not matter as long as the date is 4/21/15.

I have tried using these formulas:
=Date() & *
=Date(Now)

but these are no success.

Queries :: 2 Different Date Fields With Same Criteria

Apr 1, 2014

I am trying to figure out how to build my query that returns equipment reservations where "date out" OR "date In" are between 2 dates that are specified on my form using [Forms]![Myformname]![StartDate] and [Forms]![Myformname]![EndDate].

The purpose of the query is to find the amount of companies that have had a piece of equipment reserved between 2 dates, which could be a calendar year, or a fiscal year for example.

This is my current SQL statement that returns records where only DateIn falls between the criteria. My objective is to also return records where DateOut falls between 2 dates.

Code:
SELECT tblReservations.ReservationNumber, tblCompanies.CompanyName,
tblLookup_Contact_types.[Contact Type], tblReservation_details.Dateout, tblReservation_details.DateIn
FROM tblLookup_Reservation_Status INNER JOIN (tblCompanies INNER JOIN ((tblLookup_Contact_types INNER JOIN tblReservations ON tblLookup_Contact_types.[Contact Code] = tblReservations.CategoryID)

[Code] .....

Dcount For 2 Criteria Date Fields?

Apr 19, 2014

With a form with two fields one is a date field formatted as short date and the other is a lookup combo box that I use to lookup predefined times and is formatted as short time. The date and time are stored in the same table as date/time in separate fields. I attempted to use Dcount, and get syntax error missing operator. Below is one of a hundred that i have tried after scouring this forum and the net. I ended up converting the Appt_Time field to a text field in the table to eliminate one date field but still got no where.

Code:
Private Sub Appt_Time_BeforeUpdate(Cancel As Integer)
'Check table for duplicate
If DCount("[Appt_Time]", "tblexams", "Appt_Time= & Appt_Time & And [Sch_Date] = #" & Sch_Date & "#") > 0 Then
'Message box warning of duplication

[Code] ....

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!

Averaging Date/time Fields With A Query

Apr 15, 2008

I have a table in which each record includes a field showing the time that an event started and then another field which stores "how long did it take", these two fields are both defined as a short Time. I then have a query that runs through the "how long did it take" fields to produce an average time for the whole sequence of events. Two problems:

1. The average comes out as a decimal like 39553.367942 instead of several hours and minutes.

2. When I try to access this value using DLookup on a form I get "#error"

Any suggestions?

thanks

Problem With Date & Time Fields In Forms

Oct 11, 2006

Hi,

Im having a problem adding the date and time to a new record using a form. The 1st method i used was by inserting the default value set to Date() & Time() functions, this worked fine for over a year, but now on some computers on the network the following error pops up "function is not available in expressions in table-level validation expression".

The 2nd method I tried was to add a macro with 'setvalue' commands to the After Update event of one of the first field's that was entered, this entered the same information into the Time & Date field once the first field was updated. This now brings up the macro fault screen and the 'Halt' button has to be pressed to clear the error.

This only happens on the older computers that access the database, the new computers don't bring up any errors.

Can anyone help me with this problem??!

Contact Databse With Date And Time Fields

Apr 13, 2005

I created a Contact database where I have the date and time as two separate fields in one of the tables. I have them defined as such, but would prefer that the fields wait until I enter data into them and not auto fill with the current information. Is there a property of these fields I can set so that these fields do not get auto filled? Again this database is too large to send, so I hope that you can help without it.

Delimited Date/Time Fields Being Deleted On Import?

May 21, 2007

For anyone that might be able to help me out, I'd very much appreciate it, as this is now number 2 stupid workaround that I'd like to resolve before I need counselling...;)

I have a Date/Time field that I'm importing into my database via .csv files. The field is setup like the example below in every .csv file:

4/2/2007 8:30:00 AM

Access keeps throwing errors and deleting all the field values in this field whenever I try to import. I know that Access does this when a Date/Time field includes data that is not delimited, but these field values seem to be perfectly formatted to me... what can I do to stop Access from chucking these on import?

Right now I'm just importing the data into a "text" field, and then changing it to "date/time" afterwards, but I'm worried that once the table gets too long I won't be able to re-index all those records anymore and my database will be useless since it depends on that field being "date/time" format...

All those better than I feel free to show me how and where I've been stupid:D

Forms :: Calculated Fields - Formatting Box As Date / Time

Jan 13, 2014

In my form I have a calculated field that works out the time elapsed for a job, worked out as the QTY/RUN RATE which gives me the time in hours. However I couldn't format the box as a date/time, as it is a calculation and the times may go over 24 Hours which results in the date/time giving me something like 31/12/1899 16:00 for example.

I've got around this now and I've formatted the results as HH:NN:SS using a public function in a module, but the problem is this is now stored as a text field. I've tried setting this to a number field but the formatting doesn't carry over. I've tried setting a custom format in the table as HH:NN:SS but then all I get is just a bunch of 0's, no calculation results.

So how to format this as a number field properly?

Also for any extra information:

- I know you're not supposed to store calculated results, but this is slightly different, the calculated field is a standalone text box and the bound field is a formatted text box.
- The reason I have to store the calculated results is because my boss wants to eventually see a chart of the total hours of jobs each day, hence why I'm asking if this can be done as a number field.

Forms :: Using VBA To Populate Date / Time Fields On Subform

Jan 10, 2015

I have a form that contains a subform. On the main form, there are 3 fields: [IncidentNumber], [OpenDate] and [OpenTime]. The subform, [CtrlLog Detail] , contains the log entry details for each incident number. Every incident number can have many log entries. Two of the fields on the subform are [EntryDate] and [EntryTime]. The fields work correctly and the forms are fine.The issue Im having is when a new incident number is created the [OpenDate], [OpenTime] and [EntryDate], [EntryTime] MUST be equal because of some filter queries for statistics. Right now the user must physically type in the date/times in these 4 fields when they create a new incident number, which means I'm having lots of data entry errors.

Using default value on either [EntryDate] or [EntryTime] on the subform doesnt work because it doesnt create a primary key for the underlying table and the subform will not allow any other entry (due to some other linked values) until that PK is created. The forms are based on tables linked by [Activity_ID] as the primary key. I want to create some VBA code to see that if the Incident number is a new number (meaning the user must type in the new incident number creating the primary key for [Activity_ID]), that access will automatically populate the [EntryDate], [EntryTime] fields to match the [OpenDate], [OpenTime] fields on the main form. The user will manually populate the [OpenDate], [OpenTime].

If the number is an existing number (and the user is simply adding a log entry to the incident number) then I want [EntryDate], on the subform to default to the system date/time ([EntryTime] should remain blank for user entry) while keeping [OpenDate], [OpenTime] unchanged. When the [EntryDate], [EntryTime] fields are populated on creation of a new incident number, I want the PK for the underlying table ([Log_ID]) to be generated.

Modify Date / Time For Multiple Fields In The Record

Jul 2, 2014

automatically adding modified date/time to a record as it changes..I have a work log database for a team of people to keep track of workflow (documents in/out, stage in the workflow, owner of the record, etc.). I have a number of records that I want to automatically update a corresponding date/time field when it is changed. For example, one part of the workflow tracks a document through the approval of 5 different people. So I have a five records that are yes/no flags for approval and five records that are date/time for when it was approved. Right now my team is manually entering the five date/time stamps, but I'd like to have it automatically update when the check the "yes" box and update that field in the record.
