Q. How do you enter date in SQL Server 2008?
The general accepted form for data in SQL is YYYY-MM-DD. That is year first, followed by – then month then – than day. However depending on which country we are in, we can also use datatime in the format that the operating system understands. For exmaple we can enter
4/20/2012 which is equal to Apr-04-2012
We may also use / instead of – when entering date. E.g
04/20/2012 -- this is a valid date
