Can you do it in PL/SQL using dbms_utilty.comma_to_table and =
dbms_utility.table_to_comma to get/insert data in your table?  Or maybe =
do some bulk processing in PL/SQL?

We have a function  that loops through a table and grabs all rows
associated with a particular id and builds a string consisting of a
comma delimited, concatenate string of 1-3 rows of a column associated
with that id.

the function returns the string and that string is used to populate a
column in another table.

i believe this is possible in a single update statement but i can't
figure out how to right it. (as it is, it takes over an hour)


table a
id  col2
1    a
1    b
1    c

should populate table b like

table b
id  col2
1   1,2,3

table a can have 0,1,2, or 3 rows associated with each id.


ps.  I have lex's book on order so hopefully my sql skills will
continue to grow.
