You can use union same way:

SELECT * FROM
(
  SELECT 
    1 AS NUMQUERY, EAMEMID, COUNT(EAMATTNSTATUS)/2 as ABSENTDAYS
  FROM 
    viewDAILYSUM  
  WHERE 
    (EAMEMID = :EAMEMID) 
    AND (EAMDATE BETWEEN :FDate AND :TDate)
    AND (EAMATTNSTATUS IN (7, 8))           
  GROUP BY 
    EAMEMID

  UNION

  SELECT 
    2, EAMEMID, COUNT(DISTINCT EAMDATE)        
  FROM 
    viewDAILYSUM  
  WHERE 
    (EAMEMID = :EAMEMID) 
    AND (EAMDATE BETWEEN :FDate AND :TDate)
    AND (EAMATTNSTATUS IN (6))
  GROUP BY 
    EAMEMID
)
ORDER BY NUMQUERY, EAMEMID
