Per MSDN convert should properly parse ISO 8601 dates with timezone using 127 as the style parameter.
The optional time zone indicator, Z, is used to make it easier to map XML datetime values that have time zone information to SQL Server datetime values that have no time zone. Z is the indicator for time zone UTC-0. Other time zones are indicated with HH:MM offset in the + or - direction. For example: 2006-12-12T23:45:12-08:00.
All of the following are valid ISO 8601 dates but return Conversion failed when converting date and/or time from character string.
select convert(datetime, N'2014-02-07T13:51:00+07:00', 127)
select convert(datetime, N'2014-02-07T13:51:00+07', 127)
select convert(datetime, N'2006-12-12T23:45:12-08:00', 127)
Anyone have a solution or workaround for this issue?
Workaround?: Use datetimeoffset:
select convert(datetimeoffset, N'2014-02-07T13:51:00+07:00', 127) --<-- This one works...
select convert(datetimeoffset, N'2014-02-07T13:51:00+07', 127)
select convert(datetimeoffset, N'2006-12-12T23:45:12-08:00') --<-- and this one works...
use datetimeoffset or datetime2 instead of datetime

I have a timestamp 2020-01-08T16:06:00+00:00 format value, I want to convert it to datetime format as 2020-01-08 16:06:00.
I have tried to convert to datetime, but getting error says:
failed when converting date and/or time from character string.
I would like to convert timestamp to datetime.
If you don't care about the timezone, you can use:
select convert(datetime, left('2020-01-08T16:06:00+00:00', 19))
If you're simply interested in dropping the the offset, and not converting the timestamp to local time (as the offset sets the timestamp at UTC), try this:
DECLARE #timestamp AS DATETIMEOFFSET = '2020-01-08T16:06:00+00:00' ;
SELECT CAST ( #timestamp AS DATETIME2(0) ) AS formatted_timestamp ;
(I've assumed the data type for your timestamp is DATETIMEOFFSET. But this could also work if the data type is DATETIME or DATETIME2.)
I want to convert 19/02/2019 12.00.00 AM format to datetime in a stored procedure SQL Sercver 2012.
I tried
select cast('19/02/2019 12.00.00 AM' as datetime)
and
select convert(datetime, '19/02/2019 12.00.00 AM', 108)
but it's not working
You need to firstly replace the "." with ":" because no SQL Server time format works with ".". Then you need to use the correct format, 108 is a time only format, 103 is what you are looking for.
select convert(datetime, replace('19/02/2019 12.00.00 AM', '.', ':'), 103)
Reference
Try this with replacing (.) with (:)
SELECT convert(datetime,REPLACE('19/02/2019 12.00.00 AM','.',':'), 103)
You should have the VARCHAR literal in proper format. As other answers suggest, you can go for replace. I would prefer to represent in the below way, as it is more clear. The below one works:
Select convert(datetime, '19/02/2019 12:00:00 AM', 103)
I am suggesting to you to follow the ISO 8601 standard for datetime literals. It will take care in representing the datetime in the same way, irrespective of locale. Read more on datetime datetype. I am putting content about ISO 8601 below for your reference.
ISO 8601 Description YYYY-MM-DDThh:mm:ss[.mmm]
YYYYMMDD[ hh:mm:ss[.mmm]] Examples:
1) 2004-05-23T14:25:10
2) 2004-05-23T14:25:10.487
To use the ISO 8601 format, you must specify each element in the
format, including the T, the colons (:), and the period (.) that are
shown in the format.
The brackets indicate that the fraction of second component is
optional. The time component is specified in the 24-hour format.
The T indicates the start of the time part of the datetime value.
The advantage in using the ISO 8601 format is that it is an
international standard with unambiguous specification. Also, this
format isn't affected by the SET DATEFORMAT or SET LANGUAGE setting.
I have a column in a table with time stamps from Germany (Utc + 6) in their local time (Utc -1). How do I convert all those datetimes in my local time?
I think the correct way of converting UTC datetime into local datetime is using CLR function. You can find an example below.
https://www.mssqltips.com/sqlservertip/2339/converting-utc-to-local-time-with-sql-server-clr/
There are -7 hour between germany and central time zone in us
CT (-6)
Berlin (+1)
If your column is datetime USE THE FOLLOWING
Select DATEADD(HOUR,-7,[DATECOLUMN])
Update 1
Consider that #bdate and #edate are the begin and end date of the daylight savings so you can use this query
Select case when DATEADD(HOUR,-7,[DATECOLUMN]) between #bdate and #edate Then
DATEADD(HOUR,-8,[DATECOLUMN]) else
DATEADD(HOUR,-7,[DATECOLUMN]) end
If your data is in a string format like "dd.mm.yy," then you would use the code page 104 to tell SQL how to parse your date from string to a DateTime format.
CONVERT(DateTime, DateField, 104)
If your string is in some other format, then look up the correct codepage in the table here (CAST and CONVERT in T-SQL):
I have a date as a varchar in the form
DD/MM/YYYY HH:MM:SS AM
e.g.
16/3/2012 4:39:26 PM
I can't see a valid format option for CONVERT() in the MSDN page
Am I missing something or will I have to reformat the varchar field first?
Edit:
Corrected the format, sorry about that
Once you get your story straight, you'll want one of these:
-- if you really meant dd/mm/yyyy then:
SELECT CONVERT(DATETIME, '16/3/2012 4:39:26 PM', 103);
-- if you really meant mm/dd/yyyy then:
SELECT CONVERT(DATETIME, '3/16/2012 4:39:26 PM', 101);
But agreed with Madhivanan. Don't store dates using the wrong data type, and if you must, use an unambiguous format!
Always use proper DATETIME datatype to store dates
YYYYMMDD and YYYYMMDD HH:MM:SS are unambiguous date formats

This will work.
DECLARE #dt varchar(100)='2012/3/16 4:39:26 PM'
select convert(datetime,#dt,101)
I'm hoping to convert a table which has a DATETIMEOFFSET field, down to a DATETIME field BUT recalculates the time by taking notice of the offset. This, in effect, converts the value to UTC.
eg.
CreatedOn: 2008-12-19 17:30:09.0000000 +11:00
that will get converted to
CreatedOn: 2008-12-19 06:30:09.0000000
or
CreatedOn: 2008-12-19 06:30:09.0000000 + 00:00 -- that's a `DATETIMEOFFSET`, but `UTC`.
Cheers :)
Converting using almost any style will cause the datetime2 value to be converted to UTC.
Also, conversion from datetime2 to datetimeoffset simply sets the offset at +00:00, per the below, so it is a quick way to convert from Datetimeoffset(offset!=0) to Datetimeoffset(+00:00)
declare #createdon datetimeoffset
set #createdon = '2008-12-19 17:30:09.1234567 +11:00'
select CONVERT(datetime2, #createdon, 1)
--Output: 2008-12-19 06:30:09.12
select convert(datetimeoffset,CONVERT(datetime2, #createdon, 1))
--Output: 2008-12-19 06:30:09.1234567 +00:00
I'd use the built in SQL option:
select SWITCHOFFSET(cast('2008-12-19 17:30:09.0000000 +11:00' as datetimeoffset),'+00:00')
I know this is an old question but, if you want to convert DateTimeOffset to a DateTime, I think you need to take into account the timezone of the server you are converting on. If you just do a CONVERT(datetime, #MyDate, 1) you will simply lose the time zone, which likely results in an incorrect conversion.
I think you first need to switch the offset of the DateTimeOffset value, then do the conversion.
DECLARE #MyDate DATETIMEOFFSET = '2013-11-21 00:00:00.0000000 -00:00';
SELECT CONVERT(DATETIME, SWITCHOFFSET(#MyDate, DATEPART(tz,SYSDATETIMEOFFSET())));
The result of converting '2013-11-21 00:00:00.0000000 -00:00' to a DateTime on a server who's offset is -7:00 will be 2013-11-20 17:00:00.000. With the above logic it doesn't mater what the time zone of the server or the offset of the DateTime value, it will be converted to DateTime in the servers time zone.
I believe you need to do this because a DateTime value includes an assumption that the value is in the time zone of the server.
DateTimeoffset (Timezone) conversion in SQL Server.
SQL Server 2016 (13.x) and later
Exmample
Select GETUTCDATE()
Select Convert(DATETIME, GETUTCDATE() AT TIME ZONE 'UTC' AT TIME ZONE 'Central European Standard Time')
Select Convert(DATETIME, GETUTCDATE() AT TIME ZONE 'UTC' AT TIME ZONE 'India Standard Time')
Result will be
2020-08-18 08:22:21.640
2020-08-18 10:22:21.640
2020-08-18 13:52:21.640
Note: The timezone information is discarded in conversion if no style ("126" here) is specified. It might also be discarded in some of the other styles, I don't know -- in any case the following correctly adjusts for the TZ information. See CAST and CONVERT.
select convert(datetime, cast('2008-12-19 17:30:09.0000000 +11:00' as datetimeoffset), 126) as utc;
Happy SQL'ing.
Edit
Not sure if it matters but ... datetime Can't actually store that level of precision/accuracy. If the above is run the fractional seconds will be truncated to 3 digits (and accuracy is less than that). The same-same with datetime2 (and datetimeoffset(7)) produces a non-truncated value:
select convert(datetime2, cast('2008-12-19 17:30:09.1234567 +11:00' as datetimeoffset(7)), 126) as utc;
In order to account for daylight savings time, I used the following:
CONVERT(
DateTime,
SWITCHOFFSET(
CONVERT(
DateTimeOffset,
CONVERT(
DateTime,
[time_stamp_end_of_interval],
120
)
),
DATENAME(
TzOffset,
CONVERT(
DateTime,
[time_stamp_end_of_interval],
120
) AT TIME ZONE 'Pacific Standard Time'
)
)
)
AS GOOD_PST
Note: time_stamp_end_of_interval is a varchar
