I'm trying to select records where the start time is between 12:00 midnight and 5:00am using Access. I use this;
Sheet1.[Start Time] BETWEEN #00:00:00# AND #04:59:59#;
But it gives me zero results. I feel it's because "Start Time" is a date/Time field and displays the date before the time. I have tried formatting the field to be a Long Time field, but it keeps the date regardless. How do I remove the date from the field?
TimeValue(MyDate) will give you just the time portion of a datetime field.

The form uses begin date and end date text boxes formatted as "General Date" to filter results. They are generally filled using the calendar date picker tool as format m/d/yyyy. ODBC SQL table that it's pulling the date field from is also showing format "General Date" in Design View but the field includes date and time as format m/d/yyyy H:MM:SS AM/PM.
When the same date is entered in the form begin and end date it shows no results, but I am told by my team in the past it has shown results. I am assuming that this is due to the form date picker including no time and defaulting to 12 AM in both boxes when the query runs. If that is/may be the case, is there a way to edit the end date text box to default to 11:59:59 PM of the date selected?
10/28 EDIT: I was asked to provide the SQL that refers to the end date text box. For context: the command button on the form opens query dbo_GEN_INSP_Count_Daily which is based on query dbo_GEN_INSP_Count_Monthly where the text box is mentioned. See below.
query dbo_GEN_INSP_Count_Daily
SELECT DateValue([INSP_DTE]) AS Insp_Date, Count([INSP_DTE]) AS DailyCount
FROM dbo_GEN_INSP_Count_Monthly
GROUP BY DateValue([INSP_DTE]);
query dbo_GEN_INSP_Count_Monthly
SELECT dbo_VEHICLE.DMV_VIN_NUM, dbo_INSPECTION_GENERAL.INSP_DTE, dbo_INSPECTION_GENERAL.CI_NUM, dbo_INSPECTION_GENERAL.DMV_FACILITY_NUM, dbo_INSPECTION_GENERAL.VIP_UNIT_NUM
FROM dbo_INSPECTION_GENERAL INNER JOIN dbo_VEHICLE ON (dbo_INSPECTION_GENERAL.VIP_UNIT_NUM = dbo_VEHICLE.VIP_UNIT_NUM) AND (dbo_INSPECTION_GENERAL.DMV_FACILITY_NUM = dbo_VEHICLE.DMV_FACILITY_NUM) AND (dbo_INSPECTION_GENERAL.CI_NUM = dbo_VEHICLE.CI_NUM) AND (dbo_INSPECTION_GENERAL.INSP_DTE = dbo_VEHICLE.INSP_DTE)
WHERE (((dbo_INSPECTION_GENERAL.INSP_DTE) Between [Forms]![Form1]![StartDate] And [Forms]![Form1]![EndDate]));
I'm not sure how it would play with your ODBC connection, but in the date field in the form under the data tab in the property sheet there is a default value for the form, just like in the MS Access table. You could try to put your default time in there at 11:59:59, it will automatically put quotes around it and it should reflect in your form.
You could also create a default constraint on the database itself to reflect 11:59:59 for the end date if nothing is there. Going this route you would probably need to break up your time and date fields in the database and bring them together in MS Access with a function. That way if a date was placed there with no time it would default to 11:59:59.
When the user enters the same date for both StartDate and EndDate, you want the query to return all rows containing that date regardless of the time component stored with the date.
So, instead of your current Between ... And approach, make the endpoint target less than one day after EndDate.
WHERE
dbo_INSPECTION_GENERAL.INSP_DTE >= Forms!Form1!StartDate
And dbo_INSPECTION_GENERAL.INSP_DTE < (DateValue(Forms!Form1!EndDate) + 1)
I want to search for data between given dates. I'm able to get results that are between but it's not including the day at the beginning and end of between statement.
I tried just switching the days that use the between on such as adding or subtracting a day, but there's gotta be another way.
SQL:
WHERE "Date" Between '09/02/2019' AND '09/06/2019'
AND (sf.TemplateName = 'Nassco Lacp')
AND (sf.ProjectName = 'Crossbore Safety Program')
AND (sf.WorkOrderNumber LIKE '%2715%I1%')
I should get all data between those days including the work done on the the second and sixth, but for some reason I'm not getting stuff done on the sixth. HELP!
Don't use between with dates! The time component can cause a problem. Instead:
where date >= '2019-09-02' and
date < '2019-09-07' and -- note this is one day later
. . .
Most databases understand the YYYY-MM-DD for date constants.
In my experience this happends when the Date field is a timestamp data type. What happends is that a specific date such as 09/02/2019 it's interpreted as 09/02/2019 00:00:00 so any value before is exclured.
Try (ORACLE DBMS):
WHERE Trunc("Date") Between '09/02/2019' AND '09/06/2019'
Try (SQL Server):
WHERE cast("Date" As Date) Between '09/02/2019' AND '09/06/2019'
I am writing a SQL query for MS Access.
The two fields are DateTime. The start/end time are 22:30/6:30
When I run the following query
SELECT cDate(Format(table1.BeginTime,"hh:mm")),
I get 10:30 PM instead of 22:30. I do not want to convert to 12hrs format. How do I keep the Miliary time format?
So I tried a few things in Access 2013 and it seems that #Bjones has a point.
In SQL Server Format is a clr .net function and format(date, 'hh:mm') will be 12 hour and Format(date, 'HH:mm') will be 24 hour.
But as #Bjones pointed out there may be some question of how your original column is held as text or date or time..... And what I have concluded after trying is that your order of functions is wrong.
cDate(Format(table1.BeginTime,"HH:mm"))
cDate transforms the content to a date but it doesn't format it.
So
FORMAT(cDate(table1.BeginTime), "hh:mm")
or
FORMAT(cDate(table1.BeginTime), "HH:mm")
or
FORMAT(cDate(table1.BeginTime), "Short Time")
should give you what you want if the time is stored as text. If stored as date time you can just drop the cDate all together and stay with
FORMAT(table1.BeginTime, "Short Time")
as #Bjones answered.
You don't tell what the result of the query is intended for.
If you need the date value and to view this in 24 hour format, use:
Select table1.BeginTime
and apply a Format property for the column of h:nn or hh:nn
If you need the date formatted as a string in 24 hour format, use:
Select Format(table1.BeginTime, "hh:nn")
and no Format is needed.
In any case, even though the format string h:mm will work, do use h:nn or hh:nn, as m is for the month.
I think what you need to get rid of is the cDate function as your fields are already in DateTime format.
SELECT Format(table1.BeginTime,"hh:nn")
I have a table with a column that was previously converted using
(CONVERT(VARCHAR(19), GETDATE(), 112)
With the getdate being the date when the field was inserted. Now I have to compare the current date against the date the field was inserted.
The issue I'm facing is that when the date field is from last month, say 20131004, I calculate date difference by (CONVERT(VARCHAR(19), GETDATE(), 112) - 20131004, the result is 200. Obviously this is wrong...
Could you please suggest me how I could calculate the true date difference?
You should be using the DATE or DATETIME data type for that column. Why on earth would you ever store a date as a string? Do you know how much you lose by doing so? Validation, for one - a VARCHAR(19) column will accept 20131004 12:34 PM but will also accept nonsense values like I am not a date!.
If the data is actually good, you can simply do this instead of lazy shorthand and without any explicit conversions:
SELECT DATEDIFF(DAY, column_name, GETDATE()) FROM dbo.table;
If you get an error message with this, then you have bad data. You can identify it like this:
SELECT column_name FROM dbo.table WHERE ISDATE(column_name) = 0;
Please read:

I agree with #Aaron that you should store a date field in a date field, not a text field.
If for some reason you do want to store it in a text field then the easiest way to calculate the number of days is to convert it back to a date field and then compare it:
SELECT DATEDIFF(DAY, CAST(column_name as DATETIME), GETDATE()) FROM dbo.table
This will throw an error if the value in the column cannot be converted to a date. You'll also need to make sure that the date is formatted correctly for your database. Assuming you use the format 112 you should be ok, but if you have the value 04/12/2013 in the column is that the 4th December 2013 or the 12th April 2013? It depends on how your database is configured.
But anyway, if you always insert dates in that field then you're nuts not making it a date field.
If you need to display the date somewhere then convert it on the way out.
I'm writing some SQL queries in PL/SQL that require me to filter the records based on date. The field is a date/time type, but since I don't really care about the time I figured I'll just omit it from my where clause.
So I'm writing something like
WHERE
f.logdate between to_date('2011/01/01', 'yyyy/mm/dd') and
to_date('2011/01/31', 'yyyy/mm/dd')
To get all the records for january. I read that this is supposed to be equivalent to
WHERE
f.logdate >= to_date('2011/01/01', 'yyyy/mm/dd') and
f.logdate <= to_date('2011/01/31', 'yyyy/mm/dd')
But my final results are not what I expected: there are less records when I use the BETWEEN keyword than when I explicitly state the bounds. Is it because my assumption of what BETWEEN does is wrong?
EDIT: ah nvm, it appears that the date is not the issue. There was a subquery that I was using that was filtering its result set by date as well and was specifying date/time while I'm not.
Could you show the type of the "logdate" field (the sql create sentence could help) ?
In some databases the date type is actually a datetime field, so if you are looking for dates after "Jan 01 2011", you are really looking for dates after "Jan 01 2011 12:00:00 p.m.".
It may be your case.
if the time is set to 0:00 or something strange like that it wont work properly.
The query retrieves the expected rows because the date values in the query and the datetime values stored in the RateChangeDate column have been specified without the time part of the date. When the time part is unspecified, it defaults to 12:00 A.M. Note that a row that contains a time part that is after 12:00 A.M. on 1998-0105 would not be returned by this query because it falls outside the range.
