SQL Server Date Formats — ffffd

Question

How do I get the day of the week (in ffffd format, so Mon, Tue etc.) in SQL ? I don\'t see anything about it in the CAST and CONVERT documentation..

Answer 1

try this

SELECT DATEPART(DW, '1/1/2009')

Answer 2

I would use
SELECT CONVERT(CHAR(3),DATENAME(weekday,GETDATE()))
so as to avoid using another function in the SQL, the conversion to a CHAR(3) implicitly takes the first 3 characters.

Answer 3

You could use the DATENAME method to extract the day and then use the SUBSTRING to only take the first 3 chars.

SELECT SUBSTRING(DATENAME(DW, '09/11/2009'), 1, 3)

Answer 4

Many ways to do it, here's one way:

SELECT LEFT(DATENAME(dw, GETDATE()), 3)

Answer 5

You can't ffffd out of the box but you can do the full day

e.g.

select datename(weekday,getdate())

returns 'Monday' and you can just take the first 3 letters.

Answer 6

For SQL Server 2012+:

SELECT FORMAT(GETUTCDATE(),'ffffd') AS ShortDayName

This is much cleaner than a substring solution. The FORMAT() function can also be passed a culture for locale-aware formatting.

Note that this works for other date parts, such as month:

SELECT FORMAT(GETUTCDATE(),'MMM') AS ShortMonthName
