Solution 1

Try this:

SQL

SELECT TOP (1) A.BADGENUMBER,A.EMPNAME,A.DESIG,B.PTIME
FROM TBL_EMP A INNER JOIN TBL_PUNCH B ON B.BADGENUMBER=A.BADGENUMBER AND B.SN=A.SN)
WHERE A.SN='4550962200016'

or this:

SQL

SELECT DISTINCT A.BADGENUMBER,A.EMPNAME,A.DESIG,B.PTIME
FROM TBL_EMP A INNER JOIN TBL_PUNCH B ON B.BADGENUMBER=A.BADGENUMBER AND B.SN=A.SN)
WHERE A.SN='4550962200016'

Hi,

I believe the query below should help.

SQL

SELECT A.BADGENUMBER, A.EMPNAME, A.DESIG, B.PTIME
FROM TBL_EMP A 
LEFT JOIN TBL_PUNCH B ON B.BADGENUMBER = A.BADGENUMBER AND B.SN = A.SN
WHERE A.SN='4550962200016'

Try that, and maybe check out this really helpful article on CodeProject Visual Representation of SQL Joins[^]

Thanks,

AT PRESENT I GET THE REPORT PERFECTLY BY USING THE BELLOW QUERY
BUT IT TAKES TOO MUCH TIME FOR EXECUTION. SO I NEED TO SIMPLIFY THE QUERY FOR FAST RESULT USING JOINS OR ANY ELSE

SELECT ROW_NUMBER() OVER (ORDER BY A.EMPID) As SLNO,A.EMPID,A.EMPNAME,

(ISNULL((SELECT TOP(1)B.STATUS+'-'+B.PTIME FROM TBL_PUNCH B WHERE B.BADGENUMBER=A.EMPID AND A.SN=B.SN AND CONVERT(VARCHAR(10),B.PDATE,105)='01-04-2013' AND B.PUNCHID=1 AND B.STATUS LIKE '%%' ORDER BY PTIME ASC),'')+'/'+ISNULL((SELECT TOP(1)B.STATUS+'-'+B.PTIME FROM TBL_PUNCH B WHERE B.BADGENUMBER=A.EMPID AND A.SN=B.SN AND CONVERT(VARCHAR(10),B.PDATE,105)='01-04-2013' AND B.PUNCHID=2 AND B.STATUS LIKE '%%' ORDER BY PTIME ASC),'')) AS [Apr 01],

(ISNULL((SELECT TOP(1)B.STATUS+'-'+B.PTIME FROM TBL_PUNCH B WHERE B.BADGENUMBER=A.EMPID AND A.SN=B.SN AND CONVERT(VARCHAR(10),B.PDATE,105)='02-04-2013' AND B.PUNCHID=1 AND B.STATUS LIKE '%%' ORDER BY PTIME ASC),'')+'/'+ISNULL((SELECT TOP(1)B.STATUS+'-'+B.PTIME FROM TBL_PUNCH B WHERE B.BADGENUMBER=A.EMPID AND A.SN=B.SN AND CONVERT(VARCHAR(10),B.PDATE,105)='02-04-2013' AND B.PUNCHID=2 AND B.STATUS LIKE '%%' ORDER BY PTIME ASC),'')) AS [Apr 02],

(ISNULL((SELECT TOP(1)B.STATUS+'-'+B.PTIME FROM TBL_PUNCH B WHERE B.BADGENUMBER=A.EMPID AND A.SN=B.SN AND CONVERT(VARCHAR(10),B.PDATE,105)='03-04-2013' AND B.PUNCHID=1 AND B.STATUS LIKE '%%' ORDER BY PTIME ASC),'')+'/'+ISNULL((SELECT TOP(1)B.STATUS+'-'+B.PTIME FROM TBL_PUNCH B WHERE B.BADGENUMBER=A.EMPID AND A.SN=B.SN AND CONVERT(VARCHAR(10),B.PDATE,105)='03-04-2013' AND B.PUNCHID=2 AND B.STATUS LIKE '%%' ORDER BY PTIME ASC),'')) AS [Apr 03],

(ISNULL((SELECT TOP(1)B.STATUS+'-'+B.PTIME FROM TBL_PUNCH B WHERE B.BADGENUMBER=A.EMPID AND A.SN=B.SN AND CONVERT(VARCHAR(10),B.PDATE,105)='04-04-2013' AND B.PUNCHID=1 AND B.STATUS LIKE '%%' ORDER BY PTIME ASC),'')+'/'+ISNULL((SELECT TOP(1)B.STATUS+'-'+B.PTIME FROM TBL_PUNCH B WHERE B.BADGENUMBER=A.EMPID AND A.SN=B.SN AND CONVERT(VARCHAR(10),B.PDATE,105)='04-04-2013' AND B.PUNCHID=2 AND B.STATUS LIKE '%%' ORDER BY PTIME ASC),'')) AS [Apr 04],

(ISNULL((SELECT TOP(1)B.STATUS+'-'+B.PTIME FROM TBL_PUNCH B WHERE B.BADGENUMBER=A.EMPID AND A.SN=B.SN AND CONVERT(VARCHAR(10),B.PDATE,105)='05-04-2013' AND B.PUNCHID=1 AND B.STATUS LIKE '%%' ORDER BY PTIME ASC),'')+'/'+ISNULL((SELECT TOP(1)B.STATUS+'-'+B.PTIME FROM TBL_PUNCH B WHERE B.BADGENUMBER=A.EMPID AND A.SN=B.SN AND CONVERT(VARCHAR(10),B.PDATE,105)='05-04-2013' AND B.PUNCHID=2 AND B.STATUS LIKE '%%' ORDER BY PTIME ASC),'')) AS [Apr 05],

A.DEPT FROM TBL_EMP A WHERE A.SN='4550962200036' AND A.DEPT='All Departments'

THIS IS MY QUERY PRESENTLY USING.
