how to use dbms_xmlgen to take the results of a query and convert it into a XML formatted data. But if a column (clob) contains data in an XML format, is there a way to query that column and easily parse the data? I know that I could write loops that do string searches for each of the XML tags and nested tags.

I am working with Oracle 8i and I have a problem while applying the below query:
select to_char(ENTRYDATE,'MM-DD-YYYY HH24:MI:SS') from TBL_BANDWIDTH_READS
where ENTRYDATE > sysdate-1
and rownum <10
03-03-2011 00:00:00
03-03-2011 00:00:00
03-03-2011 00:00:00
03-03-2011 00:00:00
[code].....
The time appears as 00:00:00. I said it's something weird because if I take the where condition off, then something like this appears:
select to_char(ENTRYDATE,'MM-DD-YYYY HH24:MI:SS') from TBL_BANDWIDTH_READS
12-22-2006 13:13:27
12-22-2006 13:13:27

12-22-2006 13:13:27
12-22-2006 13:13:27
I am using the same query on a different table and there's no problem on it:
select to_char(ENTRYDATE,'MM-DD-YYYY HH24:MI:SS') from TBL_XX_PROGRAM
where ENTRYDATE > sysdate -10 and rownum <10
03-03-2011 17:06:48
03-03-2011 17:06:48
03-03-2011 16:59:08
03-03-2011 16:59:08
03-03-2011 12:04:21
I checked the DDL of both tables and the only difference is that the TBL_XX_PROGRAM have the ENTRYDATE field defined as not null and the ENTRYDATE on the TBL_BANDWIDTH_READS does not have the same constraint, could it affect?

We have been recommended to store data in CLOD data type.
Sample data: 1:2:2000000:20000:4455:000099:444:099999:....etc it will grow to a large number.
We want to create a Unique index, for functional reason. Is it advised to create a unique index on a CLOB datatype?

I am in the need of using a table type object in SQL query.
I have a package which has a spec in which I have declared :
TYPE TESTREC IS RECORD
(
RE_ID NUMBER(9),
RATING_TARIFF_NAME VARCHAR2(40),
);
TYPE TESTTABTYPE IS TABLE OF TESTREC;
TTR TESTTABTYPE;
In one of the package procedures I am collecting data into the above indicated table type object (TTR):
SELECT
RE_ID,
RATING_TARIFF_NAME
BULK COLLECT INTO TTR
FROM TESTPACKTAB;
This works fine. The values get collected into TTR and am able to print them too.
But when I :
SELECT
AA.RATING_TARIFF_NAME
INTO v_name
FROM
TABLE( TTR ) AA ;
in the same procedure immediately after the collection I get the error while running the procedure :
ORA-21700 : Object does not exist or is marked for delete.

how I can avoid PLW-07204 "conversion away from column type may result in sub-optimal query plan" (or rather the problem notified here by Oracle) from my PL/SQL code.My code looks as follows:
create table T(D date);
create or replace procedure P is
cursor C(D_IN IN DATE) is
select D
from T
where trunc(D)=SYSDATE;
begin
null;
end P;
[code]...
I don't want to disable the warning - it is there for a reason.
Additional description for the issue: It seems that D is of typ=12, while trunc(D) is of typ=13. You can use DUMP to read this info. This is described at URL....
