Retrieving from db and forcing value into an input tag

Hi as the topic stated I would like to retrive a lot of values from the database and insert them all into a single input tag

example is from the db


a b c d e f g from the same column alphabet


i would like to insert in an input type regardless of checkbox, text or hidden as long as the value is separated by comma

"a,b,c,d,e,f,g"

and later the db can retrieve it as


select *
from alphabet
where alphabet in
(
<cfqueryparam value="form.input".....>
)
