I am curious, what data store are you interacting with?

If you are using MySQL unfortunately there isn't and the OP (including
myself) probably needs this because his RDBMS does not support the array
type.

My Question would be: why are you trying to do this? You mentioned you are
working with a database, I assume that means SQL (as almost all NoSQL
Databases support some kind of JSON which doesnt require your
"workarround"). Most SQL Database support array types natively, while
support might be a

The OP needs different encoding rules per type (some of which are
unspecified, strings must be quoted, "etc."), and this could possibly be
Not sure if the OP will see this thread because I was the one that dig it
up since I had a similar problem :)

I am not sure if that's correct. I think that the final string should look
like th
I'm sorry, I've not followed this discussion - what is wrong with
user=>(apply str (interpose \, (list 1 2 3 4 5)))
"1,2,3,4,5"
the problem is strings where you want to preserve each string...you can
special case that and avoid the (apply str...) bit..
user=> (interpose \, (list "jim" "jon" "c
Using a protocol fn to do the encoding of the values according to the rules
you set per type then using clj.string/join should be quite fast and not so
horrible.

Yeah, that's exactly what I tried to implement with my `pr-to-str`,
thank you.

It still doesn't work for the list of strings. But thanks for
reminding about it.

I was seeking `interpose` function, thanks. But it still doesn't work
for strings - they are not wrapped by "\"\. E.g.
(apply str (interpose ", " (list 1 2 3 4 5))) ==> "1, 2, 3, 4, 5"
and
(apply str (interpose ", " (list "1" "2" "3" "4" "5"))) ==> "1, 2, 3,
4, 5"
The problem is that applying
I didn't do any timing, but, I would say the idiomatic way:
(apply str (interpose ", " some-vector))
