Hi, I have a recursive table containing complex SGML documents.
The table has a primary key "objectref" ; to determine what object is
actually valid, I have the columns validtime and obsoletetime, which
tell me when the object becomes, as you expect, valid and obsolete.
I ran the following query, that is supposed to return me the structure
from a specific node (identified with objectref = 7754087) up to the
top parent.
SELECT
objectref,
objectname,
objectid,
parentobjectid,
validtime,
obsoletetime
FROM
Objectnew
WHERE
validtime <= SYSDATE AND
obsoletetime > SYSDATE
START WITH objectref = 7754087
CONNECT BY objectid = PRIOR parentobjectid
ORDER BY objectid DESC;
Now, if you look at the result,
OBJECTREF OBJECTNAME OBJECTID PARENTOBJECTID VALIDTIME OBSOLETET

Can somebody explain me why I have 15 times the last row repeated (it
is the same, as identified by its primary key objectref), when I was
expecting to get it only once ?)

you have 15 records in your table where object_id of 19504 equals the
parentobject_id ...
What does parentobject_id of -1 mean in your system ?
Hey if you want unique try select distinct

I've been playing around with asyncore for one of my projects, currently

that object would start a new one as "async_http(url, returnme,
seen=self._seen)" to remember what URLs it had seen. The problem is that

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
