See the SQL query below, it count the number of Yes and No between the CheckDate

On the MatchSales field – it do not work how I wanted to be. It should find D.MobileNO (depending on the CheckDate) match to S.mobile (Check all record in the sales table)

SELECT D.Username, 
    SUM(CASE WHEN D.type = 'Yes' AND UNIX_TIMESTAMP(CheckDate) >= $From_timestamp AND UNIX_TIMESTAMP(CheckDate) <= $To_timestamp THEN 1 ELSE 0 END) as Yes, 
    SUM(CASE WHEN D.type = 'No' AND UNIX_TIMESTAMP(CheckDate) >= $From_timestamp AND UNIX_TIMESTAMP(CheckDate) <= $To_timestamp THEN 1 ELSE 0 END) as No, 
    SUM(CASE WHEN S.mobile IS NULL THEN 0 ELSE 1 END) as MatchSales
FROM dairy as D 
   LEFT JOIN (SELECT DISTINCT mobile FROM sales) as S on D.MobileNo = S.mobile
WHERE source = 'Company' 
GROUP BY D.Username

    simply add the Checkdate condition from your CASE to the where clause:

    SELECT D.Username,      
      SUM(CASE WHEN D.type = 'Yes' THEN 1 ELSE 0 END) AS Yes,      
      SUM(CASE WHEN D.type = 'No'  THEN 1 ELSE 0 END) AS No,      
      SUM(CASE WHEN S.mobile IS NULL THEN 0 ELSE 1 END) AS MatchSales 
 FROM dairy AS D     
 LEFT JOIN (SELECT DISTINCT mobile FROM sales) AS S ON D.MobileNo = S.mobile 
 WHERE D.source = 'Company'  
 AND   UNIX_TIMESTAMP(D.CheckDate) >= $From_timestamp 
 AND   UNIX_TIMTIMESTAMP(D.CheckDate) <= $To_timestamp 
 GROUP BY D.Username

    without it you will full scan dairy
