Separator in group_concat

[DSMejantel]

Hello !
I tried to write a list with multiples datas with the foldable component.
I use a group_concat.
How can I return to the next line instead to have a ',' as separator.
I've tried '/n' or '/r' or char(10) or char(13). But no change on my component...

Hi,

If you want to escape characters, you have to use backslashes i.e. '\n' or '\r' and not '/n', '/r'...

Otherwise, something like that works for me with SQLite (3.46):

SELECT GROUP_CONCAT(foo, CHAR(10));

Which database are you using?

Thanks,
I used \n' or '\r' (I wrote a mistake in the message).
I use sqlite as database

When I write :
group_concat(horodatage||' : '||nature||' --> '||notes , CHAR(10)) as description

Hello !

You need to use markdown if you want to create multiple paragraphs of text.
In markdown, you can create a new paragraph just by leaving a blank line between two chunks of text (so, you need two line break characters: one to terminate the line, and one to create a new blank line).

The following will output a b c d as a single paragraph:

select 
    'foldable' as component;
select 
    'The foldable component' as title,
    '
a

b

c

d' as description;

but the following will create multiple paragraphs, the way you want:

select 
    'foldable' as component;
select 
    'The foldable component' as title,
    '
a

b

c

d' as description_md;

(description_md instead of description)

So, in your case, with group_concat, the solution would look like this:

select 
    'foldable' as component;
select 
    title,
     group_concat(
        horodatage||' : '||nature||' --> '||notes ,
        CHAR(10) || CHAR(10) -- two line breaks between paragraphs
    ) as description_md;

Thanks,
It's ok for me with this soluce.
And thanks for this new component !
