I issue command:SELECT....FROM flashback transaction_query----QNo.103
I issue command:SELECT....FROM flashback transaction_query.
I want to know what is the output. It would return only the committed transactions or both committed and uncommitted transactions in all the undo segments?

all use the UNDO segments to reproduce the data at a previous point in time.

Parition issue when selecting from the main table
I have a partitioned table where i jsut did a partition
exchange with another temp table.
when I query the partition it looks good, i.e. the data is there, but when I query the data directly
on the table no rows are returned.
for example
select count(*)
from sales partition (2007)
12455
select count(*)
from sales
where year = 2007
0 rows
I've reviewed the parition 2007 and esnured the 'where year = ' clause is accurate via previous years.
why am i not seeing this data in the second query?
db = 10G R2
thankscreate table SALES
nologging
parallel
partition by range (year,fscl_period,channel)
PARTITION p_200701_5 values less than (2008,200702,6) TABLESPACE SALES_2007_DATA,
PARTITION p_200701_6 values less than (2008,200702,7) TABLESPACE SALES_2007_DATA,

PARTITION p_200702_5 values less than (2008,200703,6) TABLESPACE SALES_2007_DATA,
as select * from table...
note: year,fscl_period,channel are all NUMBER datatype.
Fiscal period is month bascially
I am wondering if doing this all this in a range partition, and not a range/list which channel may be better qualified for data wise, is the issue. Or perhaps range by year, sub by month, then list by channel. What will the impact be either way?
Interestingly, the data will come back on a star query i.e. when the SALES table is joined to the calendar_dim (via a day_id field) and use the 2007 predicate from the calendar_dim rather than the one on SALES (the one used for the part. definition).
Also, i did the partition exchange originally with the novalidation option. We tried again without that and the exchange failed saying some data doesn't qualify. But reviewing the data it appears it all should.
We then just did a giant insert statement and it all went through, but i have not had teh chance to validate what partitions the data live in now.
thanks for any help.

Select from .. as of - using archived redo logs - 10g
Hi,
I was under the impression I could issue a "Select from .. as of" statement back in time if I have the archived redo logs.
I've been searching for a while and cant find an answer.
My undo_management=AUTO, database is 10.2.0.1, the retention is the default of 900 seconds as I've never changed it.
I want to query a table as of 24 hours ago so I have all the archived redo logs from the last 48 hours in the correct directory
When is issue the following query
select * from supplier_codes AS OF TIMESTAMP
TO_TIMESTAMP('2009-08-11 10:01:00', 'YYYY-MM-DD HH24:MI:SS')
I get a snapshot to old ORA-01555 error. I guess that is because my retention is only 900 seconds but I thought the database should query the archive redo logs or have I got that totally wrong?!
My undo tablespace is set to AUTOEXTEND ON and MAXSIZE UNLIMITED so there should be no space issues
Any help would be greatly appreciated!
Thanks
RobertIf you want to go back 24 hours, you need to undo the changes...

Insert problem using a SELECT from table with a index by function TRUNC
I came across this problem when trying to insert from a select statement, the select returns the correct results however when trying to insert the results into a table, the results differ. I have found a work around by forcing an order by on the select, but surely this is an Oracle bug as how can the select statements value differ from the insert?
Platform: Windows Server 2008 R2
Oracle 11.2.3 Enterprise edition
(I have not tried to replicate this on other versions)
Here are the scripts to create the two tables and source data:
CREATE TABLE source_data
ID NUMBER(2),
COUNT_DATE DATE
CREATE INDEX IN_SOURCE_DATA ON SOURCE_DATA (TRUNC(count_date, 'MM'));
INSERT INTO source_data VALUES (1, TO_DATE('20120101', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120102', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120103', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120201', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120202', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120203', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120301', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120302', 'YYYYMMDD'));
INSERT INTO source_data VALUES (1, TO_DATE('20120303', 'YYYYMMDD'));
CREATE TABLE result_data
ID NUMBER(2),
COUNT_DATE DATE
);Now run the select statement:
SELECT id, TRUNC(count_date, 'MM')
FROM source_data
GROUP BY id, TRUNC(count_date, 'MM')You should get the following:
1 2012/02/01
1 2012/03/01
1 2012/01/01Now insert into the results table:
INSERT INTO result_data
SELECT id, TRUNC(count_date, 'MM')
FROM source_data
GROUP BY id, TRUNC(count_date, 'MM');Select from that table and you get:
1 2012/03/01
1 2012/03/01
1 2012/03/01The most recent month is repeated for each row.
Truncate your table and insert with the following statement and the results should now be correct:
INSERT INTO result_data
SELECT id, TRUNC(count_date, 'MM')
FROM source_data
GROUP BY id, TRUNC(count_date, 'MM')
ORDER BY 1, 2;If anyone has encountered this behavior before could you please let me know, I can't see that I am making a mistake as the selects results are correct they should not differ from what is being inserted.

Edited by: user11285442 on May 13, 2013 6:15 AMHi,
welcome to the forum. I cannot reproduce the same behavior.
Could you please post the SQLPlus output while executing all commands, like it has been done by S10390?
Also post the output of the following command:
SELECT * FROM v$version;When you put some code or output please enclose it between two lines starting with {noformat}{noformat}
i.e.:
{noformat}{noformat}
SELECT ...
{noformat}{noformat}
Formatted code is easier to read.

Performance issue after Upgrade from 4.7 to ECC 6.0 with a select query
Hi All,
There is a Performance issue after Upgrade from 4.7 to ECC 6.0 with a select query in a report painter.
This query is working fine when executed in 4.7 system where as it is running for more time in ECC6.0.
Select query is on the table COSP.
SELECT (FIELD_LIST)
INTO CORRESPONDING FIELDS OF TABLE I_COSP PACKAGE SIZE 1000
FROM COSP CLIENT SPECIFIED
WHERE GJAHR IN SELR_GJAHR
AND KSTAR IN SELR_KSTAR
AND LEDNR EQ '00'
AND OBJNR IN SELR_OBJNR
AND PERBL IN SELR_PERBL
AND VERSN IN SELR_VERSN
AND WRTTP IN SELR_WRTTP
AND MANDT IN MANDTTAB
GROUP BY (GROUP_LIST).
LOOP AT I_COSP .
COSP = I_COSP .
PERFORM PCOSP USING I_COSP-_COUNTER.
CLEAR: $RWTAB, COSP .
CLEAR CCR1S .
ENDLOOP.
ENDSELECT.
I have checked with the table indexes, they were same as in 4.7 system.
What can be the reson for the difference in execution time. How can this be reduced without adjusting the select query.
Thanks in advance for the responses.
Regards,
Dedeepya.Hi,
ohhhhh....... lots of problems in select query......this is not the way you should write it.
Some generic comments:
1. never use SELECT
endselect.
SELECT
into table
for all entries in table
where.
use perform statment after this selection.
2. Do not use into corresponding fields. use exact structure type.
3. use proper sequence of fields in the where condition so that it helps table go according to indexes.
e.g in your case
sequence should be
LEDNR
OBJNR
GJAHR
WRTTP
VERSN
KSTAR
HRKFT
VRGNG
VBUND
PARGB
BEKNZ
TWAER
PERBL
sequence should be same as defined in table.
Always keep select query as simple as possible and perform all other calculations etc. afterwords.
I hope it helps.

My "undo" command does not work in the new version of GB. Please advise. This is a real problem. I had no issues with GB from iLife 11.
Most likely you have Office 2004 which are PPC-only applications and will not work in Lion. Upgrade to Office 2011. Other alternatives are:
Apple's iWork suite (Pages, Numbers, and Keynote.)
Open Office (Office 2007-like suite compatible with OS X.)
NeoOffice (similar to Open Office.)
LibreOffice (a new direction for the Open Office suite.) -
Issuing commands from a Linux box
I need to let a Linux box send simple commands to a Windows Server host.
I am considering PowerShell Web Access but it looks complex, while the commands I need to send are quite simple (1-5 command lines).
What is the simplest way to allow a Linux box send commands to a Windows Server?
Consider that both the Linux box and the Windows Server are in the same LAN, so security is an issue but access from the web is not required.

asnAlso 'NOT IN' + nullable columns can be an expensive combination - and may not give the expected results. For example, compare these:
with test1 as ( select 1 as key1 from dual )
, test2 as ( select null as key2 from dual )
select * from test1
where key1 not in
( select key2 from test2 );
no rows selected
with test1 as ( select 1 as key1 from dual )
, test2 as ( select null as key2 from dual )
select * from test1
where key1 not in
( select key2 from test2
where key2 is not null );
KEY1
1
1 row selected.Even if the columns do contain values, if they are nullable Oracle has to perform a resource-intensive filter operation in case they are null. An EXISTS construction is not concerned with null values and can therefore use a more efficient execution plan, leading people to think it is inherently faster in general. -

Can I Select from table skipping extents linked with lost datafiles?
Hi~,
I need your help to recover my database.
I'm using oracle 9.2.0.8 at Fedora 3 with no-archive mode.
and I don't have any backup.
Last night, I experenced hard disk failure.
I tried OS-level recovery, but I lost some datafiles of tablespace.
anyway, I wanted to recover my database without data of lost datafiles.
so, I issued "alter database datafile offline drop" and
start oracle instance.
But, datafiles were not removed from dba_data_files view and
extents linked with lost datafiles were not removed from dba_extents view!
Selecting query of some table containing extents linked with lost data files,
I got "ORA-00376: file xxx cannot be read at this time" message.
So, my question is that..
HOW CAN I SELECT FROM THAT TABLE WITHOUT SCANNING EXTENTS LINKED WITH LOST DATA FILES?
Thanks.Hi,
Without being in archivelog and without backup, one can't do any sort of recovery. That's why backups and archivelog are so so important.
The offline data file command never does actually drop the datafile. It merely indicates to the control file that now the said tablespace will also be dropped. This won't update any view that the files are not supposed to be used or shown to you anymore.
This is what documentation says about the recovery of the database in the NoARch mode,
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14191/osrecov.htm#i1007937
You do need a backup in order to get those tables being read. Oracle doesn't have any feature which can offline/skip the missing extents for you and let you read the data without them.

2006-03-31 13:26:40.983 Mail[1067] Unhandled response to command SELECT: * NO Trying to get mailbox lock from process 81293
2006-03-31 13:26:42.171 Mail[1067] Unhandled response to command SELECT: * NO Trying to get mailbox lock from process 81292
2006-03-31 13:28:33.627 Mail[1067] Unhandled response to command SELECT: * NO Trying to get mailbox lock from process 81332
2006-03-31 13:38:33.316 Mail[1067] Unhandled response to command SELECT: * NO Trying to get mailbox lock from process 83190
Are these errors on the IMAP server side, or are these errors on the Mail.app side. If the latter, what should I do to fix the problem?
Thanks,

iMac (lampshade) Mac OS X (10.4.5)Greetings,
This is hard to tell. The IMAP select command is how an IMAP client (like Mail) polls each folder on the server to update its contents. The error you see logged is because Mail does not get an expected response when it issues the Select command. Now this is likely a server side issue as first Mail issues a List command to find out what server side folder are available and the commences to select them. Some servers do not properly expunge deleted folders at times and this error can result or an IMAP folder may have been named with a name that is causing problems for Mail. I have seen both.
The best remedy is to access the IMAP server using its web interface and look for folder structure issues and/or disable the Keep Synchronized option in Mail preferences for the imap account (this may or may not help). You can also try the rebuild and synchronize commands in Mail to see if it is a local Mail index that is the problem, but I would not place this on the top of the list.

Can not select from my own MV. Please help.
Hello Gurus,
I have created a MV with following clauses
CREATE or REPLACE MATERIALIZED VIEW "OWNER_NAME1"."MV_Name1"
BUILD IMMEDIATE
USING INDEX
REFRESH COMPLETE
AS
SELECT column1, column2 .... from table1,table2
where .....
I have logged in to DB with the 'owner_name1' schema itself which is the owner of the MV.
But, when I try to select from the above MV. It gives error "Ora-00942 table or view does not exist"
I can see the same under 'user_objects' view as an object of owner_name1 schema.
Could you please help me in understanding where I have gone wrong?
DB - Oracle 9i on unix platform.
Thanks in advance!
Abhijit.Oh! I missed to mention the exact steps followed by me which created error for me,
viz.
1) I have 2 Database and their users as follows
bq. i) DB1 in local server - 'localUser'
bq. ii) DB2 in remote server - 'RemoteUser1' and 'RemoteUser2'
2) 'RemoteUser2' user in DB2 has 'select' privilage on table 'RemoteTable1' of 'RemoteUser1' ( both are remote DB's users ! )
i.e. select * from RemoteUser1.RemoteTable1; --works okay when logged into RemoteUser2. no synonyms are created hence using schema_name.table_name convention.
3) Logged in to 'localUser' in DB1.
4) Created a DB link 'local_to_remote2' in 'localUser' schema ( in DB1) to 'RemoteUser2' schema (in DB2)
i.e.
create database link local_to_remote2 connect to RemoteUser2 identified by password using 'connection_string';
DBLink was created successfully.
5) I could select from the tables of 'RemoteUser2' using DB Link. (by logging in to 'localUser')
i.e. select * from RemoteUser1.RemoteTable1@local_to_remote2 ; --- gives me expected output. no issues!
6) Now, I created below MV in 'localUser' ( no need to tell in 'DB1' )
the exact syntax I used is as follows,
CREATE or REPLACE MATERIALIZED VIEW "localUser"."MV_Name1"
BUILD IMMEDIATE
USING INDEX
REFRESH COMPLETE
AS
SELECT column1, column2
From RemoteUser1.RemoteTable1@local_to_remote2
where condition1
and condition2;
The MV was created successfully, and I could see it as an 'Valid' object of 'localUser' schema.
i.e. select * from user_objects where object_name ='MV_NAME1' and status ='VALID' --- tells that above create MV is an object of owner 'localUser'
But, when I try to select from the said MV. it gives me error "Ora-00942 table or view does not exist"
i.e. select * from MV_Name1; ---- neither this
select * from localUser.MV_Name1; ---- nor this works :(
Even when I try to drop the same MV it gives me same error. :(
Could you please suggest me anything so that I will be able to select from MY OWN MV ?
Please help Gurus. -
