Here is my current SQL code,

  select   
   coalesce(cast(machinename as varchar(28)), 'Grand Total:') as 'machinename', 
  (IsNull(cast(CRATE_SMALL / 60 as varchar(24)),'0') + ':' +  IsNull(cast(CRATE_SMALL % 60 as varchar(24)),'0') ) as '1001' ,
  (IsNull(cast(CRATE_MEDIUM / 60 as varchar(24)),'0') + ':' +  IsNull(cast(CRATE_MEDIUM % 60 as varchar(24)),'0'))as '1002',   
  (IsNull(cast(NO_SCHEDULE / 60 as varchar(24)),'0') + ':' +  IsNull(cast(NO_SCHEDULE % 60 as varchar(24)),'0'))   as '9999' 
     from    ( 
    select  machinename  ,   
    sum(case when vfrm.job_id = '1001' then DateDiff(mi, 0, total_time)  end) as  CRATE_SMALL ,       
    sum(case when vfrm.job_id = '1002' then DateDiff(mi, 0, total_time)  end) as  CRATE_MEDIUM ,       
     sum(case when vfrm.job_id = '9999' then DateDiff(mi, 0, total_time)  end) as  NO_SCHEDULE
    from    ven_fullreportmaster vfrm
             INNER JOIN ven_descriptionmaster VDM ON VDM.description_id = vfrm..description_id
                    inner join ven_machinemaster vm on  vm.machine_id = vfrm..machine_id
                      where  vfrm.entry_date = convert(varchar, getdate()-7, 105)  
                      and  vfrm.shift_id =1 
                      and vfrm.is_task_completed ='Y' 
    group by   machinename  with rollup
        ) as SubQueryALias

the output :

 machinename    1001    1002        9999

  ARISTECH    0:0      0:0        10:0

  FADAL    0:0     5:0        10:0

  Grand Total:  0:0   5:0   20:0

problem:

is there a anyway to show only the column(s) whose total is greater than zero…
So, in the above example I dont want to show the column name ‘1001’.

    To add the totals row, you ought to look at the ROLLUP part of the GROUP BY clause. This can produce sub-totals as well as the grand total, depending on what your final requirements are.

    For hiding a column, there’s not a solution for that in tsql – a SELECT statement always produces result sets with the same shape (names and types of columns).

    But both may be better served by a reporting tool, if that’s where this data is going (which I expect it is, given the nature of the query). Reporting tools tend to have better post-processing facilities.
