#328593

Hi,
I'm trying to insert a date with the YYYY-MM-ddTHH:mm:ssZ format into a field with the type datetime but I'm getting an error: Conversion failed when converting date and/or time from character string.
Even if I run the following query I still get the same error:
SELECT CAST('2016-08-01T07:04:24+0000' AS datetime)
I know that this can be converted into a string with the following query but my question why isn't this recognized as a proper datetime and how can I get the table to accept it?
SELECT CONVERT(VARCHAR(50),'2016-08-01T07:04:24+0000', 127)

use the following form:

YYYYMMDD HH:mm:ss.ms

this works fine for us.

--> Date without Separator-Character

Thanks for the reply but unfortunately this format is coming from an inbound file that I have no control over. Furthermore the client insists this is the "right format" and doesn't want to change it.

Quick thought, datetime does not have any time zone awareness and only assumes UTC, convert into a time zone aware data type such as datetime2 instead.

😎

SELECT CONVERT(DATETIME2,'2016-08-01T07:04:24+01:00',127)

OR

SELECT REPLACE(REPLACE(REPLACE('2016-08-01T07:04:24+0000', '-', ''), 'T', ' '), '+000', '')

--> Take the disturbing characters away...

This will skew the value if the time zone is not UTC!

SELECT CONVERT(DATETIME2,'2016-08-01T07:04:24+01:00',127)

So there has to be a colon in between the 1 and the 0? +01:00 instead of +1000? Because I'm getting the latter instead of the former and the following code without the colon doesn't work.

SELECT CONVERT(DATETIME2,'2016-08-01T07:04:24+0100',127)

That's correct:

DECLARE @StringDate VARCHAR(40) = '2016-08-01T07:04:24+0000'

SELECT CONVERT(DATETIME2,@StringDate,127)

GO

DECLARE @StringDate VARCHAR(40) = '2016-08-01T07:04:24+00:00'

SELECT CONVERT(DATETIME2,@StringDate,127)

You could use STUFF like this:

DECLARE @StringDate VARCHAR(40) = '2016-08-01T07:04:24+0000'

SELECT CONVERT(DATETIME2,STUFF(@StringDate,23,0,':'),127)
