Answer 1

For example, lets say that you want to order your columns from least value to greatest and that you'll never have more than three values per id. Then you can use the analytic function row_number() like this to create a pivot value.
select id, val,
       row_number() over (partition by id order by val) as rn
  from your_table;And so your pivot query ends up looking like this.
select id,
       max(case when rn=1 then val end) AS val1,
       max(case when rn=2 then val end) AS val2,
       max(case when rn=3 then val end) AS val3
  from (
select id, val,
       row_number() over (partition by id order by val) as rn
  from your_table
group by id;But notice that I started out by making up answers to Justin's questions. You'll have to supply the real answers.
