RussianFrage
Um wen es reagieren kann, Wir möchten uns bei einer 11g r2 Oracle DBMS SELECT-Funktion mit PIVOT Option verwenden. Unsere Abfrage ist wie:
select * from
(SELECT o.ship_to_customer_no, ol.item_no,ol.amount
FROM t_order o, t_order_line ol
WHERE o.NO = ol.order_no and ol.item_no in (select distinct(item_no) from t_order_line))
pivot --xml
( SUM(amount) FOR item_no IN ( select distinct(item_no) as item_no_ from t_order_line));
Wie man sehen kann, XML Kommentar gesetzt ist, wenn Lauf als PIVOT XML es die richtige Ausgabe im XML-Format gibt, aber wir sind verpflichtet, die Daten als unformatierte Pivot-Daten zu bekommen, aber dieser Satz wirft Fehler: ORA-00936: fehlender Ausdruck
Jede Auflösungen oder Ideen begrüßt werden würde,
Mit freundlichen Grüßen

Lösung 2
the procedure edited at 17.01.2011 is dirty but working, looping cursors should change, better err. handling for the dynamic sql ( currently second to none), will try to improve it when got time. Thank you all for your help.

I don't have an Oracle 11 instance available to me now (PIVOT is new in Oracle 11) so I can only speculate. My guess is that the -- has ended up commenting out everything after the pivot, and Oracle has given you a 'missing expression' error because it was expecting to find something after pivot. Have you tried commenting out xml by surrounding it with /* and */ instead of putting -- before it?
If you were running this query from Java, say, then I would expect you to get a 'missing expression' error if you attempted to run the SQL in the following string:
String sql =
"select * from (SELECT o.ship_to_customer_no, ol.item_no,ol.amount " +
"FROM t_order o, t_order_line ol " +
"WHERE o.NO = ol.order_no and ol.item_no in (select distinct(item_no) from t_order_line)) " +
"pivot --xml " +
"( SUM(amount) FOR item_no IN ( select distinct(item_no) as item_no_ from t_order_line))";
Because this SQL string gets concatenated into one line, the -- in front of xml will cause Oracle to ignore everything in the query after it.
EDIT: In the procedure you added, what concerns me is this part (abbreviated):
v_sql := 'begin
select * from ...;
end;';
open DENEME for
select v_sql from dual;
I don't understand why you're using BEGIN and END within v_sql. Try removing them.
Also, take care not to leave a trailing semicolon in your SQL statement string. The following will give an ORA-00911: invalid character error if you try to run it using EXECUTE IMMEDIATE or suchlike:
v_sql := 'select * from dual;'; /* note the semicolon inside the string */
but the following will be OK:
v_sql := 'select * from dual';
Finally, it appears you want to return the results of this SQL query, not the query itself as a string. Replacing your open DENEME for ... statement with the following should do what you want:
open DENEME for v_sql;
EDIT 2: In your procedure, there is a commented-out call to DBMS_OUTPUT.PUT_LINE. Have you verified that the SQL generated here is correct? In particular, are you sure that none of the values used to form v_query_items and v_pivot_items have ' characters in them?
It may be that there is a problem using PIVOT with dynamic SQL. I don't know, and can't help much more because I don't have access to Oracle 11 here. Do you still get errors if you simplify the SQL to a much smaller query, but one that still has PIVOT in it? In other words, find a simple PIVOT query that works (e.g. you can run it successfully in SQL Developer or suchlike), write a procedure such as the following, and see whether you get any data back from it:
CREATE OR REPLACE PROCEDURE dynamic_pivot_test(
results OUT SYS_REFCURSOR
)
AS
BEGIN
OPEN results FOR 'SELECT ...'; /* put the PIVOT query here. */
END;
