If we want to compare datetime vs a specific time what should we do?
i.e.  startdatetime                     specific time
     2015-10-12 00:03:19:020               16:23:00
I want to compare just time in startdatetime coloum vs a specific time i.e. 16:23 .
I convert startdatetime to (DT_DBTIME) after that i want to calculate just time difference. how can i do it?
i.e i want to calculate this two (DT_DBTIME) columns without any date ==> (16:23:00)-(00:03:19)

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]...

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 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?

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.

Hi,
I'm trying to save times in datetime fields, but seem to have lots of issues with formats.
I'm using a multiline text box, where the user will pick from 09:00 09:30 10:00 etc, so the value that comes out in the .text property is "09:30"
Once I have that, whats the best way to convert this into the right format for a dt field? I understand it'll have todays date in it which is fine. It seems to work ok if I overwrite a textbox that's bound to a datetime field, but not if I'm sending it via an insert statement.
Also I'm using 24 hour format times, eg 14:00, do I need to do anything to ensure they're store in this format?

I have a PHP page where the user enters a date that represents the last day of a timesheet (ts_end) and the hours worked on that timesheet. That is then written into a table where the date is a datetime type. Because the user just enters a date, the time portion of the field is set to 00:00:00. In another place, I need to sum the columns for reports submitted between the beginning of a timesheet (ts_end -6 days) and the ts_end date.
The problem is that chartreviewed values entered on the ts_end date are getting lost because the time part of the ts_end field is 00:00:00 and the time part of the dateentered for the chartreviewed value is not. For instance using 2/4/2004 as the ts_end date looses the 192 charts.
Reporter activity chartsdateentered
2001576 20672 563 2004-01-29 13:55:51.000
2001576 20665 202 2004-02-02 19:54:57.000
2001576 20666 160 2004-02-03 22:48:11.000
2001576 20667 192 2004-02-04 19:41:51.000
I know I can revise the query to look for charts where the dateentered is less than dateadd(d,1,ts_end) and get the right values. It seems like there has to be a way though to tell sqlserver to ignore the time part of a datetime field when querying.
Anybody know what it is?
Thanks,
Ursus

Dear all,
I have an application where I need to implement a Team Shift management.
The team shift table need to be defined as follow :
Shift table
=========
Id DateTime IsCurrent
1 08:00:00 True
2 16:00:00 False
3 00:00:00 False
From the table above the current running shift is Id = 1
Based on that I have following question:
1 - Is there a way to specified for a DateTime field that it will recieved only Time part ?
2 - When a shift change occurs, I need to compare the Current time with the time shift in the table. Then according to that I set the IsCurrent flag to proper new Shift ID.. how to perform this ?
Thnaks for your help

Hi,
I am very new to using SQL. Our department usually uses Brio to query the various databases under our control. However, I have recently come against a problem that prompted me to create a custom SQL query which works well as far as it goes. My problem is looking for specific conditions in billing information I receive monthly. I would like to compare on of the date fields contained in the database with a field in the form of YYYYMM (200710, for October 2007) I have created a custom column generator that forms a date from the YYYYMM. I would like, however, do the translation on the fly and make the comparison during the query. The problem is that query without the date check returns a mass of data, only about 1 percent of which is what I want.
The beginning of the SQL query looks like this:
FROM From.T_Crs_Tran_Dtl WHERE T_Crs_Tran_Dtl.Crs_Bill_Yr_Mo IN ('200710', '200711', '200712') AND ((T_Crs_Tran_Dtl.Crs_Cde IN ('1G', '1V') AND (T_Crs_Tran_Dtl.Dptr_Dte < LastDay(ToDate(Substr ( Crs_Bill_Yr_Mo, 5, 2 )& "/1/"&Substr ( Crs_Bill_Yr_Mo, 1, 4 )))) AND (T_Crs_Tran_Dtl.Prev_Stats_Cde IN (' ', 'TK', 'TL') AND T_Crs_Tran_Dtl.Cur_Stats_Cde IN ('TK', 'TL') AND T_Crs_Tran_Dtl.Std_Tran_Typ_Cde='B') OR (T_Crs_Tran_Dtl.Prev_Stats_Cde='UN' AND T_Crs_Tran_Dtl.Cur_Stats_Cde='XX' AND€¦
It is the €œ(T_Crs_Tran_Dtl.Dptr_Dte < LastDay(ToDate(Substr ( Crs_Bill_Yr_Mo, 5, 2 )& "/1/"&Substr ( Crs_Bill_Yr_Mo, 1, 4 )))) AND€? part of the query that is just plain wrong. The business part of this statement takes the YYYYMM field and turns it into a date which is the last day of YYYYMM.
I hope someone out there can help me with making this comparison.
I appreciate your help.
Bill

Hi all, having a little problem with saving dates to sql databaseI've got the CreatedOn field in the table set to datetime type, but every time i try and run it i get an error kicked up Error "The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.The statement has been terminated."I've tried researching it but not been able to find something similar. Heres the code: DateTime createOn = DateTime.Now;string sSQLStatement = "INSERT INTO Index (Name, Description, Creator,CreatedOn) values ('" + name + "','" + description + "','" + userName + "','" + createOn + "')"; Any help would be much appreciated

guys this is kind of a biggie for me.
i've only used sql server to compare the Date Portion of date(s), not the whole string (mm/dd/yyyy hh:mi).
i have a table called Time_Check which has two fields with timestamps,
"TimeLastRun & TimeNextRun". i was trying to compare the Current TimeStamp that i pass from a vb.net form to a stored procedure and compare that DateTime to the TimeNextRun. I'd like to then Update the two Time Columns if rows are found. Should i maybe be using the DateDif Func if i know ahead of time how much time should be elapsed(say five minutes)?
Any Code help is appreciated
Create Procedure dbo.My_Time_Check
@myDate smalldatetime
as
select alertnumber,alertname,TimeLastRun,TimeNextRun
from time_check
where timeNextRun >= @myDate
--would like to update these two columns if rows are found
thanks again
this forum is the best

I should consider 04/07/2006 12:10 as the initial datetime, 04/07/2006 12:20 as the final datetime, and count only 10min of work to him. In code:
if(logon_time_id < start_valid_period) initialDatetime = start_valid_period else initialDatetime = logon_time_id
if(logoff_time < end_valid_period) finalDatetime = logoff_time else finalDatetime = end_valid_period
Is there anyway I can do this in a query, without using a stored procedure with "ifs" and everything else?
Thank you!

I am trying to do a select where one set of date/time columns are greater than another. My date is stored in one column while the time is stored in another. Only the date portion of the date column is valid and only the time portion of the time column is valid.
Example my date column value is 8/1/2007 01:01:01 AM and my time column value is 1/1/2007 07:23:49 AM which in my system means the last update time was 8/1/2007 07:23:49 AM.
My select statment looks like this.
SELECT *
FROM CHANGE
WHERE
CONVERT(DATETIME( DATE_LAST_ALTERED, TIME_LAST_ALTERED)) < CONVERT(DATETIME(DATE_APPROVED,TIME_APPROVED))
I get an incorrect syntax near 'DATE_LAST_ALTERED'.
Am I totaly missing the point of DATETIME?

Hi,
Can i compare date = null in stored procedure? Does this work? The syntax works but it never get into my if else statement? The weird thing here is it has been working and just this morning, it stopped. I don't know why? Could you please help? Thanks,
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER PROCEDURE [dbo].[UpdateActiveStates1]
@PROVIDERID INT
AS
DECLARE @STARTDATE DATETIME
DECLARE @ENDDATE DATETIME
DECLARE @ACTIVE BIT
SET @ACTIVE = 0
SET @STARTDATE = (SELECT ProhibitionStartDate FROM Providers WHERE ProviderID=@PROVIDERID)
SET @ENDDATE = (SELECT ProhibitionEndDate FROM Providers WHERE ProviderID=@PROVIDERID)
IF ((@STARTDATE = NULL OR @STARTDATE = '1753-01-01') AND (@ENDDATE = NULL OR @ENDDATE = '1753-01-01'))
BEGIN
PRINT 'Setting Inactive due to NULL Start Date and NULL End Date'
SET @ACTIVE=0
END
ELSE IF (@STARTDATE != NULL AND @STARTDATE <= GETDATE())
BEGIN
IF (@ENDDATE = NULL)
BEGIN
PRINT 'Setting Active due to NON-NULL Start Date and NULL End Date'
SET @ACTIVE=1
END
ELSE IF (@ENDDATE >= GETDATE())
BEGIN
PRINT 'Setting Active due to NON-NULL Start Date and NON-EXPIRED End Date'
SET @ACTIVE=1
END
ELSE
BEGIN
PRINT 'Setting Inactive due to NON-NULL Start Date and EXPIRED End Date'
SET @ACTIVE=0
END
END
UPDATE Providers SET Active=@ACTIVE
WHERE ProviderID=@PROVIDERID
UPDATE Actions SET Active=@ACTIVE WHERE ProviderID=@PROVIDERID
