Because [EntryTime] field is int and you are comparing it with 'December'

Make it like Month(EntryTime) =12 then it will work

Then you can do it like this

Datename (mm,[EntryTime]) ='December'

Does that work if I do this, using the < symbol

Datename (mm,[EntryTime]) <= 'December'

No, it will not wotk, Better you need to convert it into int and use it.
you can make a case statement if it is december then return 12 and can use it here.

Why do both of this statements produce different results?


select * from frmRegistrationCSW where Fiscal = 2013 and EntryTime <= '12/31/2012' and frmRegistrationCSWCheck11 = 1



select * from frmRegistrationCSW where Fiscal = 2013 and Datename (mm,[EntryTime]) <= 'December' and frmRegistrationCSWCheck11 = 1

I don't think that would make sense (because doing a character comparison).  Month(EntryTime)<=12 would normally make more sense except that generally that should always be true (I am unaware of any month being greater than 12 :-)).  Perhaps you would like to describe what it is you are trying to achieve?

Case statement?

Do you have an example?

Your two select statements differ because one is comparing dates (EntryTime <= '12/31/2012').  The '12/31/2012' is converted to a datetime automatically.

The select select statement doesn't make sense because you are trying to compare text (e.g. is 'January' <= 'December' in terms of text?).

You can make it like this

Declare @Month as int

Set @Month =
Case When Datename(mm, Month(EntryTime))='December' Then 12
When Datename(mm, Month(EntryTime))='February' Then 2

END
Select @Month

And then you can use Month(EntryTime) =@Month

You asked:

Why do both of this [sic] statements produce different results?

Looking just at the part that differs...

EntryTime <= '12/31/2012'

SQL Server is implicitly converting '12/31/2012' into a datetime value, and that is why it works.

Datename (mm,[EntryTime]) <= 'December'

Here, SQL Server is doing a text comparison.  In a text comparison, 'April' is less than 'December', but 'July" is greater than 'Decemeber' (textual inequality operators use alphabetical order).
