2).ResultSet result = select a,b,c from test;
3) When I Try to get the getColumnDisplaySize()for the columns,
i.e ResultSet.getColumnDisplaySize(a) is 32 (default vaule )
ResultSet.getColumnDisplaySize(b) is 16
ResultSet.getColumnDisplaySize(c) is 32
But in the code, default is returning.

// taking a stab at appropriate values
