public static void executeGetColumnPrivileges(Connection con) {  
   try {  
      DatabaseMetaData dbmd = con.getMetaData();  
      ResultSet rs = dbmd.getColumnPrivileges("AdventureWorks", "Person", "Contact", "FirstName");  
      ResultSetMetaData rsmd = rs.getMetaData();  
  
      // Display the result set data.  
      int cols = rsmd.getColumnCount();  
      while(rs.next()) {  
         for (int i = 1; i <= cols; i++) {  
            System.out.println(rs.getString(i));  
         }  
      }  
      rs.close();
