DATEDIFF Values Are Different For Exactly Same Milliseconds
Feb 9, 2015
why the results I receiving for Seconds is different? I get the same MS results.

I have a requirement to use DateDiff(Months,DateTime1,DateTime2) and this must return positive integer values.
Currently negative numbers are being returned because DateTime1 < DateTime2  or DateTime1 > DateTime2 .
The DateTime1 and  DateTime2  values are dynamic and either of them can be bigger than the other.
Any query solution so that always positive value is returned.

I have got data like this below in effective date column
2008-08-05 19:18:13.000
2008-08-05 19:17:10.000
Expected output:
2008-08-05 19:17:10
I need to truncate the milliseconds and insert the same into datetime column.
I tried as below
select convert(datetime,substring(convert(varchar,getdate(),20),1,20))
Thanks in advance

Hi,
i am trying to add milliseconds to a time. For example if i have a time of 01:01:05:000 and i want to add 0.297 milliseconds to it i use the following simplified query
SELECT CONVERT(nvarchar(20), DATEADD(ms, 0.297, '00:01:05:000'), 14) AS Expr1
However instead of getting 01:01:05:0.297 i get 01:01:05:000. Can somebody please tell me what i am doing wrong.
Thanks in advance.

Hi!
I have the difference between two dates in milliseconds. I want to convert this difference to the format hh:mm:ss.mmm, without the date. So, if the difference is bigger then one day, I would like to show it like this, for example: 36:25:14.047
How can I do this?
Thank you!

I've been working on a project to ensure that accross our entire data warehouse everything is at the same accuracy level as far as time - migrating everything to use the full hh:mis.mmm. Some places were using hh:mis:mmm (colon instead of decimal point) and many places not using milliseconds.
The SQL server portion went essentially without issue - however SSIS is not cooperating. For example I have data I am importing from a file that is in format: hh:mis (no milliseconds) that I need to compare to data from SQL (now containing full milliseconds) - matching on time ranges. Previously this was done by converting both to the "database time" datatype in SSIS and comparing. Now when converting the cTime to database time SSIS fails and complains "The value could not be converted because of a potential loss of data".
I don't want to lop off the milliseconds becuase that could create rounding errors.
I don't like it but the only option I can think of is keeping everything in string and comparing the strings... then I run into the issue of making sure to convert all sources of data into the exact same hh:mis:mmm format in text.
Is there an easier way? I know some people use "milliseconds since midnight" and so forth but that would require major reworking of the data warehouse and many packages.

I want to execute a paramterized ADO insert command into a SQL Server DATETIME column without losing the milliseconds. I can accomplish this without parameters, but that isn't what I want. Any suggestions?
It is OK that DATETIME only has a resolution of 3.33 milliseconds.

I am writing a report that Queries a SQL DB using 'SQL Server Business Intelligence Development Studio'. I have a field in the DB called duration and it is in milliseconds. I am trying to find an easy way to convert the format from Milliseconds to HH:MM:SS.Nearest I can get is the following for the field:
=Int( ((Fields! DURATION.Value/1000) / 60) / 60) & ":" & Int(((((Fields!DURATION.Value/1000) / 60) / 60) - Int(((Fields!DURATION.Value/1000) / 60) / 60)) * 60)
The output is in HH:MM. One issue with this is if the MM is say :03, it prints as :3. I lose the leading 0 so 9:03 (9hrs and 3 minutes) prints as 9:3. Where as 9:30 (9 hrs and 30 minutes) prints as 9:30 as it should.

When you view the Extended Events "Watch Live Data" is the duration in milliseconds or microseconds? I'm assuming it's milliseconds, but if you look at the timestamp difference from start to complete it doesn't add up to the duration amount? It looks like it's just the difference between the timestamps?

I'm running into a constant issue of SQL Server modifying themillisecond part of a timestamp insert from another application. Theapplication inserts timestamp which includes a millisecond portion as astring (varchar). But when an SQL Server moves this data to anothertable (for reporting), the string is inserted in a datetime field, themillisecond field invariably changes by 1-2 milliseconds for everysingle data point inserted. Given the time critical nature of this data(to a millisecond), its almost impossible to avoid this other than toleave the data as string type. But this drives the analytical reportingfolks wild as report queries based on time criteria are getting messedup. Any ideas how to force SQL Server not to mess around with themillisecond value? Does this problem exist with SQL Server 2005 as well?

Hi, I am trying to derive a column from:
mm/dd/yyyy hh:mms.fff to dt_dbtimestamp as:
(dt_dbtimestamp)(colum_name,1, 23) when I include the period and three digits for milliseconds the package fails if I leave it out it is successfull. I need to include milliseconds for my datawarehouse project. I tried many different ways and always with failure
01/23/2007 12:23:15.234 is the date(example) derived: (dt_dbtimestamp)(column_name,1,23) fails
01/23/2007 12:23:15.234 is the date(example) derived: (dt_dbtimestamp)(column_name,1,19) succeeds

I need to set a variable to datetime and time to exact milliseconds in SQL server in stored procedure.
Example:
set MyUniqueNumber = 20071101190708733
ie. MyUniqueNumber contains yyyymmddhhminsecms
Please help, i tried the following:
1. SELECT CURRENT_TIMESTAMP; ////// shows up with - & : , I want single string as in above example.2.
select cast(datepart(YYYY,getdate()) as varchar(4))+cast(datepart(mm,getdate()) as char(2))+convert(varchar(2),datepart(dd,getdate()),101 )+cast(datepart(hh,getdate()) as char(2))+cast(datepart(mi,getdate()) as char(2))+cast(datepart(ss,getdate()) as char(2))+cast(datepart(ms,getdate()) as char(4))
This one doesnot display day correctly, it should show 01 but shows 1

Hello,
My string is:
SELECT weight FROM progress WHERE dateInput = (SELECT MAX(dateInput) FROM progress) AND memberID = 1
The problem is that the MAX dateInput doesn't belongs to memberID 1. It belongs to memberID 2. What I want is that I wanna choose the MAX Date of memberID 1. I thought of maybe using datadiff function. But I don't know how to make the datediff statement. Maybe I can write the datediff statement whereby the least datediff between the dateInput and getdate() will be the row I want. I really appreciate the person that helps me this problem... Thanks 1st of all!

I am trying to select records from whatever the current date would be and 12 months before whatever the current date is. How would I go about doing this. The table that I am trying to do this with has a year column and a month column.
I was playing with the date diff function, but I can only get dates from the specified date range. I need it to be where if I run it tomorrow, it will get that day and everything within the last 12 months.

I need to get a listing of all persons who are atleast 18 years of age. A date of birth field in the database is in this format:
4/25/2008 12:00:00 AM
My solution would be where the difference between the current date and the dob is >= 18.
I tried...
select * from table where datediff(yy,dob,getdate)) >= 18.
But this only seems to subtract the years and ignore the days/months, which I need. Could anyone provide the syntax I need?
Help is appreciated. Thanks.

Hi there i am using the datediff funtion but it does not seem to be inclusive of the two dates eg
SELECT DATEDIFF(day, s_Date, e_date) AS NumberOfDays,*
FROM weekendtest
i know i could do
SELECT DATEDIFF(day, s_Date, e_date)+1 AS NumberOfDays,*
FROM weekendtest
but i was just wondering if there some other function i should use that would be more appropriate
