Buttamvs,

Try the following Sql's

Code:

SELECT INTEGER(MAX(A.COLUMN)) +                             
       INTEGER(MIN(B.COLUMN))                               
  FROM TABLE A,                                               
       TABLE B                                                 
 WHERE A.COLUMN < (SELECT MAX(COLUMN) FROM TABLE) 
 AND   B.COLUMN > (SELECT MIN(COLUMN) FROM TABLE);


OR

Code:

SELECT SUM(A.MIN_MAX) FROM                                         
(SELECT INTEGER(MAX(COLUMN)) AS MIN_MAX                       
  FROM TABLE                                                   
 WHERE COLUMN < (SELECT MAX(COLUMN) FROM TABLE)     
 UNION                                                             
SELECT INTEGER(MIN(COLUMN))  AS MIN_MAX                       
  FROM TABLE                                                   
 WHERE COLUMN > (SELECT MIN(COLUMN) FROM TABLE)) A ;


Hope this helps...

cheers
