Hi!

If I've a table like this

kk     kj      pngk      vote      
01     02      a         12        
01     02      b         10        
01     03      c          5

and I want to have a query so that it give me a result as below. 

The condition is for each record with the same kk and kj
but difference pngk will be give a mark *;
[In this example for record 1 and record 2 we have same kk=01 and kj=02
but difference pngk a and b so we give * for the mark]


kk     kj      pngk      vote     mark 
01     02       a        12       * 
01     02       b        10       * 
01     03       c         5

How should I write the query?


Thanks in advanced.
