select 
   UpdatedOn , CONVERT(varchar,UpdatedOn,100) DateTime, CONVERT(varchar,UpdatedOn,10) Date , 
   CONVERT(varchar,UpdatedOn,108) Time , substring(CONVERT(varchar,UpdatedOn,106),1,2) Day, 
   substring(CONVERT(varchar,UpdatedOn,106),4,3) CMonth,    
   substring(CONVERT(varchar,UpdatedOn,105),4,2) 
   NMonth, substring(CONVERT(varchar,UpdatedOn,106),8,4) Year,      
   left(right(CONVERT(varchar,UpdatedOn,100),7),2) Hours_12, 
   substring(CONVERT(varchar,UpdatedOn,108),1,2) Hours_24, 
   substring(CONVERT(varchar,UpdatedOn,108),4,2) Minutes, 
   substring(CONVERT(varchar,UpdatedOn,108),7,2) Second, right(CONVERT(varchar,UpdatedOn,100),2)
