[DATE] [TIME] Functions Not Working
Dec 5, 2007
Hi,
We are using [DATE] [TIME] functions in SQL Server 2000 agent jobs and SQL Server use to translate it to current data and time functions but in
SS2005 it is not replacing the functions and we are getting filename as "test_DATE_TIME" whereas we expect "test_20071204_130000"
Do we have any new functions as replacement?
Thanks
--rubs
Following is the code we are using:
declare @name nvarchar(100)
declare @name1 nvarchar(100)
set @name1 = 'test_[DATE]_[TIME]'
set @name = 'c:ackup' + @name1 + '.bak'
backup database test to disk = @name

I am trying to take a table of Customer locations and making a single string out of them. Any help would be appreciated.
Example:
CustomerLocation = "Web"
CustomerLocation = "North Carolina"
function call..
getCustomerLocations()
output:
Web,North Carolina
:confused:

This is driving me nuts..
I'm trying to extract some data from a table in oracle. The oracle table stores date and time seperately in 2 different columns. I need to merge these two columns and import to sql server database.
I'm struggling with this for a quite a while and I'm not able to get it working.
I tried the oracle query something like this,
SELECT
(TO_CHAR(ASOFDATE,'YYYYMMDD')||' '||TO_CHAR(ASOFTIME,'HH24:MM : SS')||':000') AS ASOFDATE
FROM TBLA
this gives me an output of 20070511 23:06:30:000
the space in MM : SS is intentional here, since without that space it appread as smiley
I'm trying to map this to datetime field in sql server 2005. It keeps failing with this error
The value could not be converted because of a potential loss of data
I'm struck with error for hours now. Any pointers would be helpful.
Thanks

I'm looking for a way of taking a query which returns a set of date time fields (probable maximum of 20 rows) and looping through each value to see if it exists in a separate table.
E.g.
Query 1
Select ID, Person, ProposedEvent, DayField, TimeField
from MyOptions
where person = 'me'
Table
Select Person, ExistingEvent, DayField, TimeField
from MyTimetable
where person ='me'
Loop through Query 1 and if it finds ANY matching Dayfield AND Timefield in Query/Table 2, return the ProposedEvent (just as a message, the loop could stop there), if no match a message saying all is fine can proceed to process form blah blah.
I'm essentially wanting somebody to select a bunch of events in a form, query 1 then finds all the days and times those events happen and check that none of them exist in the MyTimetable table.

There are a lot of questions posted on SQLTEAM asking how to find the beginning of various time periods. The script will create and demo 14 functions that return a datetime for the beginning of a time period relative to the datetime value passed in parameter @DAY.
I put together this script to create these functions for several reasons:
1. To allow people to find them on their own without having to post a question.
2. To allow posted questions to be answered with a reference to this script.
3. To document algorithms that work for the widest possible range of datetime values. All except for the Century and Decade functions work for any datetime value from 1753/01/01 00:00:00.000 through 9999/12/31 23:59:59.997. The Century is limited to datetimes from 1800/01/01 forward, because 1700/01/01 is not valid in SQL Server. The Decade function is limited to datetimes from 1760/01/01 forward, because 1750/01/01 is not valid in SQL Server.
4. And last, you can actually use them on your application.
The function names created by this script are:
dbo.F_START_OF_CENTURY( @DAY )
dbo.F_START_OF_DECADE( @DAY )
dbo.F_START_OF_YEAR( @DAY )
dbo.F_START_OF_QUARTER( @DAY )
dbo.F_START_OF_MONTH( @DAY )
dbo.F_START_OF_DAY( @DAY )
dbo.F_START_OF_HOUR( @DAY )
dbo.F_START_OF_30_MIN( @DAY )
dbo.F_START_OF_20_MIN( @DAY )
dbo.F_START_OF_15_MIN( @DAY )
dbo.F_START_OF_10_MIN( @DAY )
dbo.F_START_OF_05_MIN( @DAY )
dbo.F_START_OF_X_MIN( @DAY )
dbo.F_START_OF_MINUTE( @DAY )
dbo.F_START_OF_SECOND( @DAY )
There is a separate post for function dbo.F_START_OF_WEEK to find the first day of the week at this link:
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=47307
This script was tested with SQL Server 2000 only.
I posted a script for End Date of Time Period Functions here:

Edit 2006-11-01:
Added dbo.F_START_OF_X_MIN( @DAY ) at the suggestion of Peter.
Edit 2007-02-24:
Modified the following functions to use a simpler algorithm, that is shorter, runs faster, and is more suited for use with in-line code:
dbo.F_START_OF_30_MIN( @DAY )
dbo.F_START_OF_20_MIN( @DAY )
dbo.F_START_OF_15_MIN( @DAY )
dbo.F_START_OF_10_MIN( @DAY )

A common problem in moving data between SQL Server and UNIX systems is converting to/from the SQL Server datetime format to the UNIX time format.
There are several UNIX time formats, but the most common is a signed 32-bit integer that represents time as the number of seconds between 1970-01-01 00:00:00 and a given time. The functions in the script can be use to convert between SQL Server datetime and this UNIX time format.
For more information on UNIX Time, please read this link:
http://en.wikipedia.org/wiki/Unix_time
For more information about SQL Server date/time conversions, refer to this link:
Date/Time Info and Script Links
http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=64762
The conversion of UNIX Time to SQL Server datetime is fairly trivial using the SQL Server DATEADD function, and this is the logic used by the F_UNIX_TIME_TO_DATETIME function in the script:
declare @UNIX_TIME int
select @UNIX_TIME = 1111111111
-- Using dateadd to add seconds to 1970-01-01
select [Datetime from UNIX Time] = dateadd(ss,@UNIX_TIME,'1970-01-01')
Results:
Datetime from UNIX Time
------------------------------------------------------
2005-03-18 01:58:31.000
(1 row(s) affected)
The conversion of SQL Server datetime to UNIX Time is more complex. SQL Server datetime is accurate to milliseconds so is necessary to either truncate or round off the time to a whole second. The function in the F_DATETIME_TO_UNIX_TIME script rounds the time down if milliseconds is less than 500 and up otherwise. A second problem is that UNIX Time is an integer, so it can only represent time from 1901-12-13 20:45:52 through 2038-01-19 03:14:07. The range of SQL Server datetime is 1753-01-01 through 9999-12-31, so the function in the script has logic to return a NULL if the datetime is outside the valid UNIX Time range. Another minor issue is that the SQL Server DATEDIFF function will not cover the full range of an integer value with seconds, so it is necessary to have additional logic in the function do cover the time from 1901-12-13 20:45:52 to 1901-12-14 00:00:00.
The function names created by this script are:
dbo.F_DATETIME_TO_UNIX_TIME( @DAY )
dbo.F_UNIX_TIME_TO_DATETIME( @UNIX_TIME )
The script also includes code to test and demo the functions.
if objectproperty(object_id('dbo.F_DATETIME_TO_UNIX_TIME'),'IsScalarFunction') = 1
begin drop function dbo.F_DATETIME_TO_UNIX_TIME end
go
create function dbo.F_DATETIME_TO_UNIX_TIME

SET ANSI_NULLS ON

[code]...
I need a function or stored procedure which will return the date which is 15 working days (should exclude holidays and Weekends) prior to the given future Date? the future date should be passed as a parameter to this function or stored procedure to return the date. Example scenario: If i give date as 12/01/2015, my function or stored procedure should return the date which is 15 working days (should exclude holidays and Weekends) prior to the given date i.e 12/01/2015...In my application i have a table tblMasHolidayList where all the 2015 year holidays dates and info are stored.

I have a table of sales transactions that I'd like to group by date, but this is a datetime field so it groups by the date and time, and so it returns more records that I want. Is there an easier way to do this other than using the datepart function to build a date? How can I just look at only the date of a datetime field?

I am trying to load previous days data at 3 am via a SSIS job.
The Date variable is initiated as DATEADD("dd",-1, GETDATE()) in the for loop.
Now, as this job runs at 3 am, and I set the variable as GETDATE() - 1, it excluded the data from 12 am to 3 am in the resultset as Date is set as YYYY-MM-DD 03:00:00:000 I need this to be set as YYYY-MM-DD 00:00:00:000

CheckOutTimeDateTime
InOutStatusbit
HoursWorked?--------> What shoulud be DataType?
When an Employee Checks in All fields are set and
InOutStatus is set to 1 Except CheckOutTime and
HoursWorked.When The Employee checks out InOutStatus is set
to 0,CheckOutTime is set and then i have to calculate the
HoursWorked (TimeDuaration). Constarins are CheckOutTime is
always greater than CheckInTime.(There may be different
dates for them as employee gets check in ,Nov 29,2005 on
time 17:00 and checksout , Nov 30,2005 on time 03:30).Now
according to calculation he worked for 10 hours and 30
minutes .How to calculate this hours worked(only time
duration and to which datatype it should be saved in sql)
as well as the Stored Procedure for this whole
process.Whenever Employee comes his Emp_Id is only known.

Hi there.
I'm trying to extract data from my SQL server & everything in the script I've got is working (extracting correct data) except for one field - which is for the most part it's off by +2 days (on a few occasions - I see it off by just +1 day or even +3, but it's usually the +2 days).
I'm told that it's due to the conversion formula - but - since SQL is not my native language, I'm at a bit of a loss.
The DB table has the date field stored as a type: CHAR (as opposed to 'DATE')
Can anyone out there help?
Please advise. Thanks.
Best.

Dear Expert!
A server with SQL 2005 sp2, Reporting Services and Sharepoint services (ver 3.0) (in integrated mode) gives an odd error. When viewing a Reporting Services report with a Date Time Picker, the date chosen is wrong. The preferred setting is Danish with the date format dd-mm-yyyy. The date picker shows the months in Danish but when selecting a date, and clicking on the Apply-button, the date reformats to US (mm-dd-yyyy).
Example:
When choosing 5th of September 2007 and clicking apply, it shows in the picker, 9th of May 2007.
When choosing 26th of September 2007 and clicking apply, it shows, again in US format, the RIGHT date but adds a timestamp 12:00 AM? in the end, making further enquiries to fail.
The report itself receives the right date and shows correctly. The only case it fails is, when the time stamp appears.
The server is a 32-bit one with 4 GB RAM. A testserver with identical collation on the Reportserver database cannot recreate the error. The site containing the reports has been set to Danish in the regional settings. To Reinstall is not an option.
The test report has no database connection whatsoever.
When setting the site to US, the timestamp wont appear at all.
The server has been restarted and the installation procedure was of the simple kind. No special tweaks at all.
Any advice would be greatly appreciated.
Kind Regards

Hello,
we need to track date/time of last update for each record in a table.
As we understand it, we can't use field type Timestamp as this type does
not use dates/times.
Is there any SQL function available which we can bind to a column or
do we really have to use triggers?

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

I want to display only the date part of a date field which contains both date & time information.
For example I have the value '2013-11-14 00:00:00.000' in my result set, and ideally I would like to show only '2013-11-14'.
I have looked up the datepart() command, however I can't work out how to return all parts of the date, rather than just the year, month, or day.

I have a table named "shift" and I need to setup my query to return only data where the field "startime" = today. The problem I am running into is the starttime field it laid out like "2005-12-29 14:00:00" with different time values. I need to ruturn everything that has todays date regardless of the time value. I tried using GetDate() but that is returning data for other days as well or just data before or after the current time. Does anyone have any suggestions? This is driving me crazy! Thanks, Garrett

Hello,
We have a bunch of Audit tables that contain almost exact copies of the operations tables. The audit tables also include:
AuditID - the audit action (insert, modify - old, modify - new, deleted)
AuditDate - date and time of action
AuditUser - User who did it...
At the end of the day I need to know for any given record what it looked like at the beginning of the day and what it looks like at the end of the day. There could have been numerous changes to the record throughout the day, those records I am not interested in. Only the first record and the last record of a give day.
I am going to be doing a lot of MIN(AuditDate) and MAX(AuditDATE) and .. WHERE AuditDate BETWEEN '10/1/2007 00:00:00' AND '10/1/2007 11:59:59' ...
Question: Whats better for performance:
1. Separating out the date and time and doing a clusterd index on the date.
2. Keeping date and time in the same column and just use a normal index.
3. Better ideas?
Thanks,
Bradley

dbo.KALENDER.HALBJAHR_BEZ1, dbo.KALENDER.HALBJAHR_BEZ2, dbo.KALENDER.QUARTAL_WERT, dbo.KALENDER.QUARTAL_BEZ1,
dbo.KALENDER.QUARTAL_BEZ2, dbo.KALENDER.MONAT_BEZ, dbo.KALENDER.MONAT_WERT, dbo.KALENDER.TAGE_IM_MONAT,
dbo.TAG.KALENDERWOCHE, dbo.TAG.WOCHENTAG, dbo.TAG.TAG, s.STUNDE_ID, s.DATUM_ZEIT
FROM dbo.KALENDER INNER JOIN
dbo.TAG ON dbo.KALENDER.KALENDER_ID = dbo.TAG.KALENDER_ID INNER JOIN
dbo.STUNDE AS s ON dbo.TAG.TAG_ID = s.TAG_ID
WHERE ((SELECT MONTH(s.datum_zeit) AS Expr1
FROM ) =
(SELECT MONTH(GETDATE()) AS Expr1) - 2) AND
((SELECT YEAR(s.datum_zeit) AS Expr1
FROM ) =
(SELECT YEAR(GETDATE()) AS Expr1))
ORDER BY s.STUNDE_ID
... but this causes syntax-errors. I don't understand why this query works fine in the query editor but then gets automatically "destroyed" by the view editor. Do i have to use more statements to get the working query to run inside a view?
Thanks alot for reading.
