How can I combine 2 queries?

Question

I have these below queries in fastreport. I would like to combine them together into one query. How can I do this ?

SELECT 
    EAMEMID, COUNT (EAMATTNSTATUS)/2

You can use conditional aggregation:

SELECT EAMEMID,
       SUM(CASE WHEN EAMATTNSTATUS in (7, 8) THEN 1 ELSE 0 END) / 2 as ABSENTDAYS1,
       COUNT(DISTINCT CASE WHEN EAMATTNSTATUS in (6) THEN EAMDATE
             END) as ABSENTDAYS  
FROM viewDAILYSUM  
WHERE (EAMEMID = :EAMEMID) AND
      (EAMDATE between :FDate and :TDate)
GROUP BY EAMEMID  
ORDER BY EAMEMID
