I am trying to deduct a datetime field from a date field to decide how many days are in between. It doesn't let me. So do I need to convert the datetime field to a date field first? How would I do that?Or is there a function I can use to calculate the date difference?
I want to make query where I want to show data only from time1 to time2 (for a month).
I want to make this in Access because I need Forms.
I made this on the SQL Server but I had to change the time limits in the code what I don't like. How to make this in Access SQL?
On the SQL server it looked like this:
SELECT * FROM TimeSample WHERE TimeVal - CAST(FLOOR(CAST(TimeVal AS float)) AS datetime) > '10:00' AND TimeVal - CAST(FLOOR(CAST(TimeVal AS float)) AS datetime) < '17:00'
I'm sure this is simple but my brain is mushy this morning!
I have two datetime fields ADMISSION and DISCHARGE with values such as 03/02/2008 15:00. How do I convert these to dates only? I don't want to just *format* them as dates, which I can do. In this example I would want to convert that date to 03/02/2008 (or 03/02/2008 00:00)
It's an idiosyncrasy of the way the NHS calculates hospital length of stay. Our previous IT system had dates and times in separate fields so I could just ignore the time field and work out length of stay based on dates only. However, our new system returns a combined datetime.
Patient A 03/02/2008 00:15 to 03/02/2008 23:45 = 0 days but Patient B 03/02/2008 23:45 to 04/02/2008 00:15 = 1 day
Basically, you count a day if there's a date change, even if that was only half an hour (or even a few minutes) either side of midnight, but you DON'T count a day if there was no date change, even if that was almost 24 hours.
So formatting them as dd/mm/yyyy wont work ,as I will still have partial days when I subtract one from the other and INT([DISCHARGE]-[ADMISSION]) wont always work either as it would calculate 0 for patient B.
Is it possible to convert the text field that comes in this form:
:80421
to the following datetime format: MM/DD/YY 12:00:00AM
Please note that the text field contains a colon at the beginning. The number 8 represents a year (2008), the 04 represents a month (April) and the last two characters are days in the month (21). The converted field should look like:
I have a table that looks like this: Code:ID Station DateTime Value 1 ABQ 10/8/2005 1:00 am 102 ABQ 10/8/2005 2:00 am 203 ABQ 10/8/2005 3:00 am 254 ABQ 10/8/2005 4:00 am 5... I am trying to build a query that, for each record, gives me the values for the previous 2 hours.
So my goal would be a query that returns: Code:ID Station DateTime Value ValueT-1 ValueT-21 ABQ 10/8/2005 1:00 am 10 Null Null2 ABQ 10/8/2005 2:00 am 20 10 Null3 ABQ 10/8/2005 3:00 am 25 20 104 ABQ 10/8/2005 4:00 am 5 25 20...
I created a table (NewTable) that, for each record, has the DateTime, DateTimeT-1, and DateTimeT-2. So columns in Newtable are ID, Station, DateTime, Value, DateTimeT-1, DateTimeT-2 where DateTimeT-1 = dateadd("h",-1,DateTime) and DateTimeT-2 = dateadd("h",-2,DateTime).
I then joined (using a left join) this new table to the original table on [NewTable].[DateTimeT-1] = [OldTable].[DateTimeT]. so code is Code:select [NewTable].ID, [NewTable].Station, [NewTable].DateTime, [NewTable].Value, [OldTable].DateTime, [OldTable].Value AS ValueT-1from NewTable left join ON [NewTable].[DateTimeT-1] = [OldTable].[DateTimeT]
The output does not pull all the right records. Some of the records have Null values for ValueT-1 when the datetimeT-1 is in OldTable. So for some reason the join doesn't seem to be working.
Hopefully this is clear. Any thoughts? Help is very much appreciated!
I have a form that pulls in open project information that has a datetime field called "Duetime". What I'm attempting to do is that when this datetime field is less than 1 hour away, to turn the field background orange. Also, if less than 30 minutes to actually being past due, then it would be red.
I'm losing my mind on this one. Here is my situation... I receive a daily excel sheet with these fields. I would like to import this workfile into access and would like to manipulate it anyway I want. The problem I'm coming into is that I can't collapse/group the datetime field into just the date when I run a query. I would like to be able to run a query on any date range the client registered, a query on any and all the unique dates the client purchased something, all the unique clients, etc. Here is a sample
Sales Name - Sales # - Client Name - Client # - Registered Dt - Purchased Dt Paul, John - 273 - Kelly, Maria - 2252 - 7/26/2007 18:22 - 8/4/2007 10:21 Paul, John - 273 - Kelly, Maria - 2252 - 7/26/2007 18:22 - 8/5/2007 18:20 Paul, John - 273 - Kelly, Maria - 2252 - 7/26/2007 18:22 - 8/6/2007 10:21 Paul, John - 273 - Kelly, Maria - 2252 - 7/26/2007 18:22 - 8/6/2007 13:28 Paul, John - 273 - Kelly, Maria - 2252 - 7/26/2007 18:22 - 8/6/2007 13:28 Paul, John - 273 - Kelly, Maria - 2252 - 8/7/2007 01:22 - 8/9/2007 05:46
I would like it to show...
Sales Name - Sales # - Client Name - Client # - Registered Dt - Purchased Dt Paul, John - 273 - Kelly, Maria - 2252 - 7/26/2007 - 8/4/2007 Paul, John - 273 - Kelly, Maria - 2252 - 7/26/2007 - 8/5/2007 Paul, John - 273 - Kelly, Maria - 2252 - 7/26/2007 - 8/6/2007 Paul, John - 273 - Kelly, Maria - 2252 - 8/7/2007 - 8/9/2007
and a different query like ( the purchase date doesn't matter here)...
Sales Name - Sales # - Client Name - Client # - Registered Dt - Purchased Dt Paul, John - 273 - Kelly, Maria - 2252 - 7/26/2007 - 8/4/2007 Paul, John - 273 - Kelly, Maria - 2252 - 8/7/2007 - 8/9/2007
I read in other places to change the format, input mask, convert, char, etc. but nothing. Please tell me exactly what to do. I don't care if the time changes to midnight or 0:00:00. I will owe you my first born child.
I am having an issue setting an instantiated forms' control. I am having RemDate ("Date") and RemTime ("Time") TextBox; so far the date textbox shows 1/1/1988 12:00 AM (the visible value is the time only) and the Time textbox doesn't show anything.
Code: Set frm = New Form_ReminderAssigneesFrm frm.RecordSource = "Select * from ReminderAssignees Where RemID = " & Parent.RemID frm.RemID.DefaultValue = Parent.RemID With SetRS(frm.RecordSource) If Not .EOF Then frm.RemDate.DefaultValue = FormatDateTime(.Fields("RemDate"), vbShortDate)
I have a field on a table that is a DateTime format and it needs to be that way. I am trying to query that table for all the dates to use in a combobox but I only wat the date not the time. The problem is when I format the field to just date I can't sort it anymore as a date and I can't group them. I still get multiple lines in my combobox because there multiple times for the same day. what is the proper way in a query to extract just the date from a field and still sort it as date ie 1/12/2015 is greater than 12/15/2014?
I have a report that shows a datetime field and I would like to show only the time portion of the field on my report. Is there a way for me to do that?
I would like to add fields from one table to another based on matching datetime codes.
Most data are in the table 'metadata' (information on sound recordings), and i want to add lat long fields from a large table of GPS points 'gpsData'. Each record in the metadata table has start and end datetime fields - i want to a add lat and long that matches the start time and a lat and long that matches the end time (so four fields to metadata).
My approach has been to try this with two separate select queries (i.e. one for adding the start locations and one for adding the end locations), with the intention of then combining these two outputs in a single table.
When i try a simple select query though I can see that:
a) there are no matching time codes for some records, because although the hh:mm:ss look the same there are differences in the lesser decimal places of the datetime serial numbers. I have tried using the round function on the datetime fields of both tables but this doesn't fix it (I don't understand why not).
b) there are some duplicates because there are sometimes more than one GPS point for each second, and the metadata times are given to second precision (so some metadata records get two entries in the query result).
How can I have the query select the gpsData record with the nearest datetime stamp to that in the metadata table's start time field? The respective field names are UTC and StartUTC. Can i do the same for the end times simultaneously or should i do this separately?
I have a table with 'General Date' column. So I have to create query wich extracts records between Last record (via Date field) and 'for example' 10 days before. But Last record in Date column may differ from Now().
When this is done I have create calculations with extracted records using agregate functions.
I'm trying to use Last function for Criteria putting it into Date field and substracting with -10 (for 10 days) but it doesn't work.
I have a larget transaction data set in access with Datetime column/filed.
I have been running pivot queries to excel to do analysis of the data but the datetime field is returning too many unique values for the pivot table to run.
What is the best way to reduce the datatime field to date only and where should this be done?
i.e. should I have a calculated field that trims datetime or should I set someohting up in Powerpivot?
I am new to access 2010. I have a table called "Forecasts", and I wish to update the timestamp with todays date, whenever the user makes a change to the qty of goods forecasted.
I have been researching online for the solution to the correct format to datetime, but it doesnt seem to work.
Code: Dim todayDate As Date todayDate = Date Dim sqlString As String sqlString = "UPDATE [Forecasts] " & _
[Code] .....
The messagebox shows:
UPDATE [Forecast] SET Branch_Plant=123, Item_Number_Short='222', Description='AAA', UOM='EA', Estimated_Cost=123, Requesting_Business_Unit='AAA', End_Customer='CCC', Project ='Secret', Timestamp=#26/12/2013# WHERE ID =24
Then I hit a syntax error. Whats wrong with sqlString?
I have a date and time stamp in a Date/Time field of General Date format (3/1/2006 7:52:25 AM).
I wish to select query on the table's Date/Time field by date portion only (3/1/2006) and not include the time portion (7:52:25 AM) of the field.
Using this expression in the query's criteria - "Between [Enter Start Date: (MM/DD/YY Format)] And [End Date: (MM/DD/YY]" will not return the date ranges as desired without also typing in the full time string.
How can the date integer be parsed out and the query properly expression ed on the criteria field without using VB?
We have both Access 2003 and Access 97 users on our network and i have a database that is written in 97. But lately we've been getting unrecognized format when we open it. So my guess is someone out there is opening it in 2003 and converting it. Is there a way to tell the database to ONLY run on 97 and DO NOT convert to a different version?
I am running an Access Database for a large uk companys call centre.. I use many diffrent systems which allow me to show our centres productivity...
I have hit a wall
When i first developed the DB i used the time formatting hh:mm:ss but later down the line i found if you *the time by 86400 it converts the hh:mm:ss into a workable seconds format....
One of my old extracts that i feedinto the DB are in the old format therefor i do this calculation within an access query which *the time by 86400
however i have found an probelm.. if the time is over 24hrs it seems to double the time there or there abouts in seeconds
example
01/01/1900 01:42:00 which is basically 25 hrs should be around 92520 seconds
when is do this calculation in an access query it is coming out 178920 all the other times are correct so this rules out how i link 2 querys ....
Hi, hope someone here has experience with this issue.
Our system was recently converted to much tighter secured network environment and moved to Office 2003 (still Windows XP).
Within the next couple of weeks we expect to split/secure our new db for shared use across a network (approx. 6-8 users at any one time).
I want to keep the db in 2000 as long as possible because I'm doing lots of the work at home and that's what I have. After deployment there will be lots more changes but in managed releases. (sounds official, eh?...)
Does anyone know of any risks I'm running by keeping it in 2000 within Access2003?
Hi. I have a db with a numeric field called Eur_2. This field is populated with data imported from an excel file. When the Eur_2 excel field contain Null, in the correspondent Access Field the value inserted is 0 (zero). I have necessity to put in the Access field Null value. The VBA code that I use for import is:
Eur_2 = XL.Application.Cells(indriga, indcolonna + 10) If Eur_2 = 0 Or _ Eur_2 = Empty Then Eur_2 = Null End If
but when i open the Access table, the value inserted is 0 (zero). There's something to do for change 0 (zero) to Null?
