How to get a particular date format ('dd-MMM-yyyy') in SELECT query SQL Server 2008 R2

Question

I am using CONVERT(data_type(length),expression,style) function to change the format of a date in a SELECT query.

Declare @dt nvarchar(20)

Answer 1

I Think this is the best way to do it.

REPLACE(CONVERT(NVARCHAR,CAST(WeekEnding AS DATETIME), 106), ' ', '-')

Because you do not have to use varchar(11) or varchar(10) that can make problem in future.
