I have the following 2 select statements which I would like to merge having the entry and exit times next to each other in table based on the Date column which must match.

     SELECT NAME, SURNAME,IDENTIFIER, CONVERT(VARCHAR,(MIN(TRANSIT_DATE)),114) AS [ENTRY],'' AS      [EXIT], CONVERT(VARCHAR(10),TRANSIT_DATE,103)AS [DATE] 
  FROM [10.230.0.15].[SCAT].[dbo].[HA_TRANSIT] a
  WHERE STR_DIRECTION = 'Entry'
  and a.IDENTIFIER = '20045619'
  AND STR_TRANSIT_STATUS = 'Granted'
  AND TRANSIT_DATE BETWEEN @CompleteSDate AND @CompleteEDate
  GROUP BY NAME, SURNAME,IDENTIFIER,CONVERT(VARCHAR(10),TRANSIT_DATE,103) 


 SELECT NAME, SURNAME,IDENTIFIER, '' AS [ENTRY],CONVERT(VARCHAR,(MAX(TRANSIT_DATE)),114) AS [EXIT], CONVERT(VARCHAR(10),TRANSIT_DATE,103)AS [DATE] 
 FROM [10.230.0.15].[SCAT].[dbo].[HA_TRANSIT] a
 WHERE STR_DIRECTION = 'Exit'
 and a.IDENTIFIER = '20045619'
 AND STR_TRANSIT_STATUS = 'Granted'
 AND TRANSIT_DATE BETWEEN @CompleteSDate AND @CompleteEDate
 GROUP BY NAME, SURNAME,IDENTIFIER,CONVERT(VARCHAR(10),TRANSIT_DATE,103)

RESULTS of Query 1 NAME SURNAME IDENTIFIER ENTRY EXIT DATE ANTONETTE COLEMAN 20045619 07:11:01:000 10/09/2013 ANTONETTE COLEMAN 20045619 06:58:58:000 11/09/2013 ANTONETTE COLEMAN 20045619 07:04:27:000 12/09/2013 ANTONETTE COLEMAN 20045619 07:02:48:000 13/09/2013 ANTONETTE COLEMAN 20045619 07:17:43:000 16/09/2013 ANTONETTE COLEMAN 20045619 06:54:35:000 17/09/2013 ANTONETTE COLEMAN 20045619 07:00:36:000 18/09/2013 ANTONETTE COLEMAN 20045619 06:57:33:000 19/09/2013

You probably don't need two SELECTs, the only difference in your WHERE-conditions is STR_DIRECTION. Just move it into CASEs:

   SELECT NAME, SURNAME,IDENTIFIER,
       CONVERT(VARCHAR,(MIN(CASE WHEN STR_DIRECTION = 'Entry' THEN TRANSIT_DATE END)),114) AS [ENTRY],
       CONVERT(VARCHAR,(MAX(CASE WHEN STR_DIRECTION = 'Exit'  THEN TRANSIT_DATE END)),114) AS [EXIT],
       CONVERT(VARCHAR(10),TRANSIT_DATE,103)AS [DATE] 
   FROM [10.230.0.15].[SCAT].[dbo].[HA_TRANSIT] a
   WHERE STR_DIRECTION IN ('Entry', 'Exit')
   AND a.IDENTIFIER = '20045619'
   AND STR_TRANSIT_STATUS = 'Granted'
   AND TRANSIT_DATE BETWEEN @CompleteSDate AND @CompleteEDate
   GROUP BY NAME, SURNAME,IDENTIFIER,CONVERT(VARCHAR(10),TRANSIT_DATE,103)

UNION

 SELECT NAME, SURNAME,IDENTIFIER, '' AS [ENTRY],CONVERT(VARCHAR,    (MAX(TRANSIT_DATE)),114) AS [EXIT], CONVERT(VARCHAR(10),TRANSIT_DATE,103)AS [DATE] 
FROM [10.230.0.15].[SCAT].[dbo].[HA_TRANSIT] a

AND STR_TRANSIT_STATUS = 'Granted'
AND TRANSIT_DATE BETWEEN @CompleteSDate AND @CompleteEDate
GROUP BY NAME, SURNAME,IDENTIFIER,CONVERT(VARCHAR(10),TRANSIT_DATE,103)
