How do I convert eg '22/03/2005' to a datetime in SQL Server

It开发者_StackOverflow社区s SQL Server 2000. I am starting with a character string in the format DD/MM/YYYY

---

Here's the table: http://msdn.microsoft.com/en-us/library/ms187928.aspx

Sample:

select convert(datetime,'22/03/2005', 103)

---

SET DATEFORMAT dmy
SELECT CAST('22/03/2005' AS datetime)

or 

SELECT convert(datetime,'22/03/2005', 103)

It depends your the context.
SQL Server understands '2010-06-21' as a date without requiring any convert/cast, so I would just use the string in the format 'yyyy-mm-dd' if that suits your needs.
Otherwise, the other responses using cast may be better if you need to compare with date fields containing hours as well.
