Does BETWEEN with dates actually work in SQL SERVER 2008

Question

According to cdonner, in his answer here and on his blog.

He claims that BETWEEN with date yields inconsistent results

You are correct that his code is flawed due to string comparisons.

However, if you're using a datetime type rather than the new date type it doesn't matter. The reason is that you don't typically want an inclusive search anyway, and so rather than code like this:

SELECT * FROM [MyTable] WHERE MyDateColumn BETWEEN @StartDate AND @EndDate

you'd normally write it like this:

SELECT * FROM [MyTable] WHERE MyDateColumn >= @StartDate AND MyDateColumn < @EndDate

where @EndDate is actually one greater than the day you really want.

I expect the problem is fixed for the new Date type, but I don't have SQL Server 2008 handy so I can't test it.
