csv, array or alternative in mysql table?

[kiqyou_vf]

im sort of a newbie to all of this and my terminology isnt accurate but
i have a couple simple questions. ive been looking around for a way to
insert multiple and seperate strings (like an array or a csv file)
inside of one row "cell" in a MySQL table. for examlpe id like to
insert "review1... , review2..., review3..., review4..." inside a row
"cell". id also like to be able to do a loop on them so i can format
each string. is it possible to insert an array into a "cell"? anyway,
if you could direct me in the right direction, i can figure the rest
out for MySELF. THANKS!

I have no idea about MySQL but Postgres does this. I'm guessing thats not
an option for you.

There are about a million reasons why you do not want to do this. The
normal approach is to create a second table and put each value into a row
in that table, something like this:

create table parent (
somekey char(10),
..other columns..)

create table child (
somekey char(10),
column1 char(10))

The idea is that the common column "somekey" links values from the child to
the parent.

i THINK i see what your sayin, each row on the child table is linked to
a certain column in the parent table?

Yes, that's it. In PHP you can loop through these with code like the
following (assuming postgres, substitute mysql or whatever as appropriate):

$results = pg_query(
"select column1
from child
where somekey = '$valueofintere st'");
while ($row = pg_fetch_array( $results) {
...do something with entry
}

Buy one of Celko's books on db design, or ask a lot of questions over in
comp.databases, it will really be a big help.
