i have sql query below

FROM tblEmployee

it give result "Dec 29 2015 12:00AM"

The SQL CONVERT function converts between formats - and the DATETIME specifier 103 does indeed generate "mm/dd/yyyy".
Unfortunately, it only works when you feed it a DATETIME value to convert to a VARCHAR or NVARCHAR value - so if you are getting "Dec 29 2015 12:00AM" from your SELECT, then that's because you are storing your dates in VARCHAR or NVARCHAR fields already, and SQL won't convert from a string based field to a string based field.
Try it yourself:
SELECT convert(nvarchar, GETDATE(), 103) as 'Date Of Birth1',
       convert(nvarchar, GETDATE())as 'Date of Birth2',
       convert(nvarchar, convert(nvarchar, GETDATE()), 103) as 'Date Of Birth3'

Always store values as the appropriate datatype: anything else will give you problems later.
Change your database design now, before it does become a problem to fix - or at some point an invalid date value will get in there, and it will get to be a real problem to sort out!

Well explained, deserves a 5
Format 103 yields to the desired output so most likely if the value isn't shown correctly the problem lies elsewhere.

Have a try with
SELECT convert(nvarchar, GETDATE(), 103) as 'Date Of Birth'

the result is
Date Of Birth

However, the length for the nvarchar should be defined since without specifying the length it would be 1. In other words you should prefer
SELECT convert(nvarchar(10), GETDATE(), 103) as 'Date Of Birth'

Don't worry about those, they come and go :)

:laugh: I don't worry about 'em!
But gawd, some people'd think they were worth money or something. ;)

They aren't worth a pound each? What a pity :)

I'd be happy if they were worth a Canadian dollar each!
