Beginner with crosstab queries

I am having headaches trying to display some data in one table.
An example of some of the contents from the table are below:

ID ENTRY_ID SCHOOL
--------
1 10 Arizona
1 20 Arizona State
1 30 Texas
2 10 Baylor
2 20 Texas
3 10 Colorado

As you can see each ID has its own entry id, depending on how many school are assigned to that ID. The table has 1 to up to 10 entry_ids for each ID. The schools can be any of 70+ schools in the database, not just these that I listed.

I would like to list each school in its own column like below:

school1 school2 school3
----------
Arizona Arizona State Texas

school1 school2 school3
----------
Baylor Texas null

school1 school2 school3
----------
Colorado null null

I already know ahead of time that the highest count of entry_id per id is 10 because of a Having query I ran. Will I need to create 10 separate Select statements for each scenario??

This is what I have so far, but this is for ids with 5 entry_ids:
SELECT a.school, b.school, c.school, d.school, e.school
FROM table a,
table b,
table c,
table d,
table e
WHERE a.id = b.id
AND b.id = c.id
AND c.id = d.id
AND d.id = e.id
AND a.school > b.school
AND b.school > c.school
AND c.school > d.school
AND d.school > e.school

Unfortunately, it will not work for anything other than rows with 5 entry_ids per ID. I would hate to write out 10 different UNIONs if there is an easier way.

Your help is much appreciated and I hope I have given enough detail for an answer.Try this link (http://asktom.oracle.com/pls/ask/f?p=4950:8:7213782571237635933::NO::F4950_P8_DISPL AYID,F4950_P8_CRITERIA:7086279412131,)
