How to update more than one records at one time

Question

hello guys..
how to update a few records (more than one) with different
IDs at the same time? i tried to make a query like this (see
below), but only one record (more than one data in the same
field)has been updated.
<cfquery name="rec" datasource="DatKoku">
select *
from tbl_pilih
where id_pel = '#form.idpel#'
</cfquery>
<cfquery name="updtrecord" datasource="DatKoku">
update tbl_pilih
set
kptsn = '#form.suk_pil#',
trkh_kptsn =
'#Dateformat(TodayDate,"dd/mm/yy")#|#TimeFormat(Now(),"hh:mm:ss
tt")#'
where id_pel = '#rec.id_pel#'
</cfquery>
<cfquery name="outputrecord" datasource="DatKoku">
select *
from tbl_pilih
where id_pel = '#form.idpel#'
</cfquery>

Answer 1

Take the query,
<cfquery name="rec" datasource="DatKoku">
select *
from tbl_pilih
where id_pel = '#form.idpel#'
</cfquery>
If every row in the table has a distinct id_pel, then what
you ask is actually an impossible question. It will have no answer.
Distinct IDs imply that the resultset will contain
at most one distinct value of id_pel. That means, there can
be at most one row that satisfies the condition,
where id_pel = '#rec.id_pel#' in the update query. That in
turn means the update query can update at most one row at a time.
If, however, the resultset of
rec consists of multiple rows, it will mean that there are
multiple rows in the table that have the same
id_pel . Then, your update query,
updtrecord, should update all the rows that share that value
of id_pel.
