Billy:
I like your answers in the groups.
Especially something like this:

Damn, don't you just love SQL! :-)
I have yet to find a query that can not be done in
SQL..

I feel that I'm wrong but here is task which I can't
solve in sql.
Can you?

Problem is I can't use PL/SQL for two reasons:
1) I work trough JDBC
2) Our DBA do not give me permission to use any
procedure.

Actually I have third reason - this is not our
database, we can read only and
it is so big and impractical... It looks for me that
they don't know anything
about relations and just use tables as flat files ((

Anyway, here is question.
We have table which holds tree structure in such way:

View 1
Owner Item Sequence Level
a a1 1 1
a a2 2 2
a a3 3 3
a a4 4 1
a a5 5 2
b b1 1 1
b b2 2 1
b b3 3 2
b b4 4 3

I need SQL which produces each item with its path.
Like this

View 2
Owner Item Level1 Level2 Level3
a a1 a1
a a2 a1 a2
a a3 a1 a2 a3
a a4 a4
a a4 a4 a5
b b1 b1
b b2 b2
b b3 b2 b3
b b4 b2 b3 b4

Problem is that this table is huge, has many owners
and each of them
has own sequence.

Of course I can do it in the application. Even they do
it in this way.
They have special process (which they run every week
which
translates table with View 1 to additioanal table with
View 2.
Of course such "syncronization" only makes whole
system worse ((

Any idea how I can use SQL only to handle this?

Thanks in advance,
Alex Kizub.
