I hope this posting finds everyone doing well.

I received a SQL table with a nvarchar(255) column with dates as strings, below are a few examples.

Sun Aug 19 19:01:17 +0000 2012
Thu Oct 13 21:35:22 +0000 2011
Fri Apr 13 03:24:38 +0000 2012
Mon Nov 28 03:05:30 +0000 2011
Wed May 27 01:30:07 +0000 2009
Fri Jul 22 00:27:20 +0000 2011

I wanted to see if anyone knew how to convert these to datetime.  I have been trying the convert method with no luck.  I figure I would ask on here before I started writing my own SQL function to do this.

Many thanks!

declare @dt varchar(255) = 'Sun Aug 19 19:01:17 +0000 2012'
select cast (RIGHT(@dt,4)+ ' ' +substring(@dt,5, len(@dt)-14) as datetime )

If you don't need the offset -- for example, it's always +0000 anyway, you can do this:

    CAST(  RIGHT(string, 4) + SUBSTRING(string, 4, 17)  ) AS datetime

I'm trying, I really am. But I've seen so many wrong approaches involving date(time) boundaries I despair about my inability to explain it. I've seen quite a few recently that define a non-leap year as 364 days, or 366 days and the list goes on. …
