Question

Given this output to one query:

ID   |  Question  |  Answer

1    |     1      |    2
1    |     2      |    5
1    |     3      |    5
2    |     1      |    2
2    |     2      |    2
3    |     4      |    7

Is there any way in sql to have something like:

ID   |  Question  |  Answer
1   
     |     1      |    2
     |     2      |    5
     |     3      |    5
2    
     |     1      |    2
     |     2      |    2
3    
     |     4      |    7 

The objective is to not repeat ID over and over, but i have nothing to group by for as i want to show all results individually.

I have tried working around GROUP BY but without much results so far.
I’m using SQL Server.

You need to

• insert extra rows for headings
• remove the ID from the detail row
• make sure the order is correct, so the right headings are over the right details.

Example:

select
    -- Show the ID only if it is not a detail row
    case when Question is null then ID else null end as ID,
    Question, 
    Answer
From 
(
    -- Detail rows
    select ID, Question, Answer from T1
    union all
    -- Heading rows
    select distinct ID, cast(null as type) as Question, cast(null as type) as Answer from T1

)x
order by 
    -- In order of ID
    x.ID, 
    -- but make heading rows come first
    case when x.Question is null then 0 else 1 end asc, 
    -- then order by question
    x.Question
