If you are selecting data from a database and that database happens to be
Oracle look at the connect by clause. It does everything you are looking
for.
that's really interesting, I've never heard of connect by. can you or
Ross provide more detail, i.e. what does the resulting recordset look
Hi
does any know or have an example of how to store
multiple vectors inside a hashtable?
thank

Joe,
You can get more information at otn.oracle.com or do a search on google.
I believe these type of queries are called Hierarchical Queries.
Your DBA should be able to provide you

I have a recursive looping problem here.
For example, say I have this table
id, name, parent
1,john,4
2,bill,3
3,cathy,4
4,jackie,0
5,jeff,4
6,joe,7
7,amy,0
Essentially,
jackie doesn't have a parent, but has john, jeff and cathy as children. bill
is the child of cathy and thus jackies
are
that you have loaded all this data that may or may not be used.
Let me know if you need more detail...

I haven't tested the code and wrote it in less than 10 minutes so you might want to try it out first but solution should be along one of those lines... Code below is probably a combination of JSP, asp, vb and java so use jsp equivalent of course

meant to say use java equivalent, not jsp equivalent because a bean should be
used like Chris just mentioned...

I had to do this once... fun problem.
First of all, forget about doing it in JSP... you should use Java classes
for this.
Two ways to do it, IMO. If you have a large and flat dataset, i.e. many
records in the table but no trees

1. The easy way if you are using an oracle database, this gets them all in
one query
select name
from table
start with id = ?
connect by parent = prior id
2. use a stack
Brief example...
class Person {
int id;
String name;
Person(int id, String name) {
this.id = id;
this.name =
16 matches
