How to convert the system date format to dd/mm/yy in SQL Server 2008 R2?

Question

I'm using SQL Server 2008 R2. I want to convert the system date to this format: dd/mm/yy

"2013-01-01 00:00:00.000" to "Score Calculation - 10/01/13".

My column contains the data:

1. DMS01A13010101
2. RMS01A13010201
3. 44
4. 2013-01-01 00:00:00.000

What I want: if the record has 2013-01-01 00:00:00.000 in this format then only I change to Score Caculation - dd/mm/yy

My code is,

select 
   case 
      when (CHARINDEX(D30.SPGD30_TRACKED_ADJUSTMENT_X, '-*') > 0 or 
            CHARINDEX(D30.SPGD30_TRACKED_ADJUSTMENT_X, '*-') > 0) 
      then 'Score Calculation - ' + CONVERT(VARCHAR(8), D30.SPGD30_TRACKED_ADJUSTMENT_X, 1) 
    end checkthedate 
from 
    CSPGD30_TRACKING D30

Answer 1

   SELECT CONVERT(varchar(11),getdate(),101)  -- mm/dd/yyyy

   SELECT CONVERT(varchar(11),getdate(),103)  -- dd/mm/yyyy

Check this . I am assuming D30.SPGD30_TRACKED_ADJUSTMENT_X is of datetime datatype .
That is why i am using CAST() function to make it as an character expression because CHARINDEX() works on character expression.
Also I think there is no need of OR condition.

select case when CHARINDEX('-',cast(D30.SPGD30_TRACKED_ADJUSTMENT_X as varchar )) > 0 

then 'Score Calculation - '+CONVERT(VARCHAR(11), D30.SPGD30_TRACKED_ADJUSTMENT_X, 103)
end

EDIT:

select case when CHARINDEX('-',D30.SPGD30_TRACKED_ADJUSTMENT_X) > 0 
then 'Score Calculation - '+
CONVERT( VARCHAR(11), CAST(D30.SPGD30_TRACKED_ADJUSTMENT_X as DATETIME) , 103)
end

Answer 2

The query below will result in dd/mm/yy format.

select  LEFT(convert(varchar(10), @date, 103),6) + Right(Year(@date)+ 1,2)
