My query as follows

SQL

select b.cmn_minor_code as Course,c.cmn_minor_desc as Eligbility,convert(char(12),b.cbm_batch_start_dt,106) as Startdt,
convert(char(12),b.cbm_batch_end_dt,106) as Enddt from tb_rankwise_coursesettings as a,CO_BATCH_MASTER as b,CO_MINOR_MASTER as c
where a.course = b.cmn_minor_code and a.Rank = 'CHENGR' and b.cbm_active <> 'd'
and b.cmn_minor_code = c.cmn_minor_code
and a.Active <> 'd' and b.cbm_batch_start_dt between  '2015-08-01 00:00:00.000' and 
 '2015-09-30 00:00:00.000'

when i run the above query output as follows

Course         Eligbility         Startdt         Enddt

Solution 1

What you want is more or less user interface's job. Once you have the data, make sure you use proper UI control/tool that can display it the way you want.

I strongly suggest what has been mentioned on the Solution 1. That I also feel this is the responsibility of the UI (Crystal Reports, Excel etc...) to decide how the details should be displayed.

But if the requirement to have it on the database side, you also can use a similar method what's shown below.

SQL

CREATE TABLE #TestTable(
	Course			VARCHAR(10)		NOT NULL
	,Eligibility	VARCHAR(20)		NOT NULL
	,StartDate		SMALLDATETIME	NOT NULL
	,EndDate		SMALLDATETIME	NOT NULL
)

INSERT INTO #TestTable
        (Course
        ,Eligibility
        ,StartDate
        ,EndDate
        )
VALUES	
('REO','CHIEF ENGINEER','10-Aug-2015','21-Aug-2015')
,('REO','CHIEF ENGINEER','24-Aug-2015','04-Sep-2015')
,('REO','CHIEF ENGINEER','14-Dec-2015','25-Dec-2015')
,('REO','ENGINEER','26-Dec-2015','28-Dec-2015')
,('REO','ENGINEER','29-Dec-2015','31-Dec-2015')



SELECT 
    IIF(A.Sort_ID<>1,'',A.Course) AS Course
	,IIF(A.Sort_ID<>1,'',A.Eligibility) AS Eligibility
    ,A.StartDate
    ,A.EndDate
FROM(
	SELECT  
		ROW_NUMBER() OVER (PARTITION BY Src.Course,Src.Eligibility ORDER BY Src.Course,Src.Eligibility) AS Sort_ID
		,DENSE_RANK() OVER(ORDER BY Src.Course,Src.Eligibility) AS Rank_ID
		
		,Src.*
	FROM #TestTable AS Src
) AS A
ORDER BY A.Rank_ID,A.Sort_ID
