hi...

i have a tbl
fooTBL
name
parentID
ID

so a name can have might have a parentID, as well as an ID. 'name's are
associated with other 'name's via the parentID. in other words, if a name's
parentID == a name's ID, name1 is the parent of name2.

name parentID ID
foo - 1
cat 1 2
dog 2 3

my question, how can i come up with a sql query that will list all the
children (and children's children...) of a top level item?

i had done this awhile ago.. but can't recall how i did it..

thanks
