Detect No Time Entered For Datetime
Jul 20, 2006
I have a VB.NET program that displays the time extracted from a SQL Server database datetime datatype by way of a User-defined scalar function I created. However, sometimes information is entered into the system through the program that does not have a time-- only a date. SQL Server automatically assigns a time of 12:00 AM to these values (since they're a datetime). Is there any way to detect when this happens in my user-defined scalar function so that when I try to extract time values, I can instead return a message/time of my choice? I would rather not assume that all 12:00 AM values are automatically inserted by SQL Server since this might not actually be the case.

Hi again,
In ASP.net, is there any elegant way to handle a set of time inserts from a form when the 2nd time is past midnight?
Specifically, I have a form with 2 textboxes on it (startTime and endTime) that are set up to accept time values (using AJAX MaskedEditExtender for formatting/validation - pretty cool). This data is posted to a sub that enters the data into a table (T_Details). However, I've noticed that the data inserted as part of the record (SQL field is smalldatetime) doesn't take into account the fact that a time value past 23:59:59 in the "endTime" textbox is a time on the next day - it simply rolls to an A.M. date for the same day as the date for the pre-midnight value from the "startTime" textbox.
I'm sure that I can simply do some conditional coding and modify the date if necessary but is there a better way to do it? Thanks as always...this forum is a great resource

Hi, I wonder where I can see last update over a table. Maybe sqlserver write some information about every table.
For example there are 300 tables in a database an I want to execute some query to see the last tables updated (list of tables updated > 2008-01-02 )
Hope to be clear,
Best regards
Ariel

Nothing difficult, I just need a way to generate a new datetime column based on the column [PostedDate], datetime. So basically I want to truncate the time. Thanks a lot.

e.g.
1st March 2005 12:00:00
is showing as
01/03/2005 00:00:00
instead of
01/03/2005
Why does this happen?

I hope to update a DateTime column value with a Time input parameter. Poor attempt below but it looks like the @ApptTime param is coming in as 10:45:00.0000000 and I might have an existing @SendOnDate as: 2015-10-05 07:00:00.000...I hope to end up with 2015-10-05 10:45:00.000
ALTER PROCEDURE [dbo].[SendEditUPDATE]
@QuePoolID int=null
,@ApptTime time(7)
,@SendOnDate datetime
[code]...

Hi
i have the following situation. in my database i have a datetime field (dd/mm/yy hh:mms) and i also have a field timezone.
the timezone field has values in minutes that i should add to my datetime field so i have the actual time.
afterwards i split the datetime into date and time.
the last part i can accomplish (CONVERT (varchar, datetime, 103) as DATEVALUE and CONVERT (varchar, DATETIME, 108) as TIMEVALUE).
could anybody tell me how i can add the timezone value (in minutes) to my datetime value ?
i do all the calculations in my datasource (sql).
Thanks
V.

Sorry if this has been asked befor, but I couldn't find anything that hepled me.
I have a datetime field and want to extract only the time. I know it works with CONVERT and style-type 108. But I get something like this: 08:00:00 and I need something like this: 08:00.
Can this somehow be done?

Hi all,
I am generating a report dynamically using ReportViewer control. I use a SELECT query to fill the dataset which in turn is used by the ReportViewer to display records. One of the fields is [End Date] and is a DateTime in SQL Server. When the ReportViewer is populated, the End Date field shows the time also with the date. How can I remove that time part? I have used these methods and I want to keep the value as DateTime only and not convert to a string or something.
These don't work for me: CAST(FLOOR(CAST(m.[End Date] AS float)) AS datetime)
DATEADD(day, DATEDIFF(day, '20000101', [End Date]), '20000101')
dateadd(day,datediff(day,0,[End Date]),0)
Please can someone help.
Thanks.

I looked at this post and it didn't work for me.
Trying to extract the time portion from a datetime field. ex 7:15:12 AM from 1/1/2008 7:15:12 aM
This is what I tried and neither functions give me the results I want....
SELECT DueTime, CONVERT(varchar, DueDate, 108) AS Expr1, SUBSTRING(CAST(DueDate AS varchar), 10, LEN(DueDate)) AS Expr2, CAST(DueDate AS varchar) AS Expr3FROM TODO
Due Time Expr1 Expr2 Expr3
1/1/2008 5:15:00 PM 00:00:00 12:00:00 AM Jan 1 2008 12:00:00 AM
It seems Cast(DueDate as varchar) is the problem it converts the time to the default 12:00:00 AM
In the above example I want 5:15:00 PM
Tx in advance

I have a field that contains only a date, and a field that only contains times. If I try to add the two together, I get some meaningless date like year 2111.
The raw data looks like this
EVT_DT='2005-12-05 00:00:00'
EVT_TM='2005-12-06 13:59:00' //today's date
I wrote a function that gives me the minutes past midnight for the EVT_TM
and use a dateadd(n,myMinutesFuntion(EVT_TM),EVT_DT), but it kills the performance in the nexted cursor.
Thanks,
Carl

I have a function that accepts 2 DATETIME parameters. When the user passes a time other than midnight, the function returns a different result. Is there a simple way to strip the time from the variables?
Here's the declaration:
ALTER FUNCTION [dbo].[NumBusinessDays]
(
-- Add the parameters for the function here
@StartDate DATETIME,
@EndDate DATETIME

Hi,
I have a DateTime Column and I need to update the Time Part of it, without changing the Date Part.
For Example:
STARTDATE:
04.08.2008 12:30:00
UPDATE TO:
04.08.2008 14:40:00
I tried something like:
UPDATE table SET STARTDATE = '14:40:00' WHERE GUID = '{82F99509-3C44-4D24-96D0-CF3753C0C353}'
But this will also change the Date to 1.1.1900.
Any advise?

Hi everyone, this is the exception:
System.Data.SqlClient.SqlException: The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value
Here's my code!
... 'datagrid code
cmdSelect.CommandText = "SELECT * FROM [Table] WHERE [Date and Time] > '" & Me.tbFromDate.Text & "' AND [Date and Time] < '" & Me.tbToDate.Text & "'"
...
Me.tbFromDate.Text and Me.tbFromDate.text look like this: 27/11/2003 1:11:43 PM
The SQL Query works fine - just that this code gives a runtime error.
Can someone help?? I'm guessing I have to do somekind of conversion!!

I am doing a temporary retro-upgrade right now. So, I know this isn't exactly in the scope of ASP.Net. Ordinally my posts are. However, I need a VBScript example of how to insert the Date only into the DateTime field of an SQL 2000 Server. By default, if you try to, the server automatically adds the date "1/1/1900". Can anyone help me please?

Hi,
I want to store time into a datetime datafield in MS SQL Database, but eventually, it was include a date prefix the time ! I had try the approach on following and get the invalid result.
Approach 1:
Dim strTime as String = "11:59:59 AM"
Output:
01-01-1900 11:59:59 AM
Approach 2:
Dim dtTime as DateTime = "11:59:59 AM"
Output:
1/1/0001 11:59:59 AM <- (error occur: unable add to DB cause date is not between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM)
* The time on the above is accompany with AM/PM.
Approach 3:
Dim strTime as String = "11:59:59 AM"
Dim strStartTime2 = DateTime.ParseExact(strStartTime, "hh:mm:ss", System.Globalization.CultureInfo.CurrentCulture)
Output:
01-01-1900 11:59:59 AM
Approach 4:
Dim strTime as DateTime = "11:59:59 AM"
Dim strStartTime2 = DateTime.ParseExact(strStartTime, "hh:mm:ss", System.Globalization.CultureInfo.CurrentCulture)
Output:
String was not recognized as a valid DateTime.
I know what cause the approach 4 get an error. That is because the strTime is declare as DateTime and that contain "AM/PM" in time.
My Question:
1]Can I just insert the time only to the DB without date?
2]If possible, what should I delcare in the variable(String/DateTime/..?)
3]How can I deal with the "AM/PM"? It must concate with time to identify daytime/night
If you know and have the solution, pls do me a favor and will be more appreciated.
Thank you
Calvin

What is the best method for ignoring the time in datetime comparisons. Say I want all records on 07/08/1996 regardless of their time. Or all records between 01/01/1999 and 04/01/1999 even if one of the records on 04/01/1999 had a time of 16:32:22

I would like to be able to insert a time value only into a SQL 7 table colum which has been set as a datetime datatype. When I insert '12:34:44 PM' into the colum it actually inserts '1900-1-1 12:34:44 PM'. An Access table will allow you to insert the time value without adding the '1/1/1900' date value. Can this be done in SQL7?
Thanks for any help.

Hello all,
Perhaps someone out there could enlighten me on the issue of date/time (particularly time) storage.
I am trying to get the time component to be stored in a Datetime field. I can do a Date only as follows:
INSERT INTO Test ([DateTime])VALUES(Cast(convert(char(10),GETDATE(),102) as Datetime))
I attempted the following:
INSERT INTO Test ([DateTime])VALUES(Cast(convert(char(8),GETDATE(),108) as Datetime))
But I cannot get the time component without the default date 1/1/1900 component.
If any of you gurus out there can help me out it would be very much appreciated.
Thanks!

I am trying to produce a report that will show a duration in minutes of a time when a room was occupied for a category. Whilst I have the start and end dates and times, the end user must be able to specify not only a range of dates, but a start and endtime of hours in the day in which they are interested in (it will be applied to all days in the range - they are not allowed to specify a different start/endtime per day).
The example I have is a date range of 6 to 17 October, but they only want the times from 09:00 to 21:00, so if a room was occupied from 08:00 to 11:00 they would only want to know the duration as 120 minutes (09:00 to 11:00) not 180.
The data is supplied by a third party, and duration in minutes is supplied, but it is not much use when they are not interested in the 'real' duration.
CREATE TABLE [dbo].[Evts](
[Location_name] [nvarchar](200) NULL,
[Event_Category] [nvarchar](500) NULL,
[Start_Time] [datetime] NULL,
[End_Time] [datetime] NULL,
[Duration] [int] NULL
[Code] ....
---but the expected output is
Location_nameEvent_Categoryduration
RS8CM240
RS8OD480 -- eliminating 08:00 - 09:00 on 17th
RS8OOT300 -- eliminating 08:00 - 09:00 on 13th
RS8SCC150
RS8SODT1740
RS8 SODT180
RS8SODTB60
RS8SODTNT180
RS8TR60
Looking for info regarding to the minute calculation when the start time specified by the user differs from that of the actual startime?
