Flashback query: Historical rows not always returned

Hello all,
I have a problem using flashback queries, like e.g.
SELECT id, description, versions_starttime, versions_operation, versions_xid FROM testtable VERSIONS BETWEEN TIMESTAMP MINVALUE AND MAXVALUE
The point is, that the historical rows are returned only for a certain period of time. Executing the above query after a certain period of time will result in returning only the current rows in the table (having versions_xxx columns returned as NULL).
Do you have any ideas how I can fix it so I can always access the historical rows?
Is it possible to use flashback queries to implement a complete history mechanism (including restore of rows) ?
Many thanks in advance and best regards,
Martin

Flashback query works, but not flashback versions query

This is a test database (Oracle10g 10.1.0.5), not in archivelog mode. I deleted one row 2 hours ago. I can still use flashback query:
select * from tm_instances as of timestamp to_timestamp('STARTTIME_HERE') to view this row. But I can't use the following flashback versions query:
SELECT versions_startscn, versions_starttime,
versions_endscn, versions_endtime,
versions_xid, versions_operation from tm_instances VERSIONS BETWEEN TIMESTAMP to_timestamp('STARTTIME_HERE') and MAXVALUE
It gave the following error:
ORA-30052: invalid lower limit snapshot expression
So I guess flashback query works better than flashback versions query?
undo_retention is set to 900 by default here.
Thanks,

currently function returns all mydate rows, i just want mydesired date rowsCheck if there is a column in the table with the same name as the function parameter. It's the most probable reason of such DML operations behaviour in PL/SQL procedures and function.

SQL Query Single Row not working

My workflow contain a Query Single row activity. I have added a where clause in Arabic which is not working. If I remove the Arabic condition its working.
Is there something to do with the server?
My server is windows 2008 R2 Server.
The same workflow is running perfectly on another identical environment.
Thanks for any valuable suggestions,

Hi Sastry,
Connection to the database is trough Pivotal, I have tried ODBC connection as well but same error
The instruction at "0x005d53e0" refereced memory at "0x00000014'. The memory could not be "read".
With ODBC I have always compilation error saying
Query Engine Error: '42000:[Microsoft][ODBC SQL Server Driver][SQL server] Incorrect syntax near the keyword 'SELECT'. '.
but even the simple select statment is showing the error.
Do you think the error is with Drivers???

Query rewrite does not always work?

Hi -
I created several cubes at this point.
Cube #1: simple time and volume. Query re-write works great.
Cube #2: simple customer (geography) hierarchy and volume. Query re-write works great.
Cube #3: Added product dimension along with time and customer. I also added ytd volume and same period prior period volume calculations.
The Cube#3 is not peforming a query re-write.
All cubes have MV and Query rewrite enabled.
I am using lastest verisons of 11G and AWM.
Any ideas how to debug why query rewrite is not working?
Thanks,
Frank.

In range and coerce function does not always return a correct result

I passed 20E6 as DBL to "upper limit" input of "in-range and coerce" built-in VI, and also passed 20E6 as DBL to the X input of the VI, yet it says that it is not in range. (Note: lower limit was hardwired to 0.)
Apparently, there is some kind of roundoff error going on with LabVIEW.
I've seen this before when just wiring 2 doubles of the same value to an "=?" built-in VI.
When I display 30 digits or so, the values then display slightly differently.
How do 2 numbers which were entered by ME (not anything else) precisely as 20E6 manage, over time or by passing thru VIs, or by being copied & pasted -- or whatever -- to become "different"?

This simpliest 'In Range and coerce' does not work on my setup (8.0 and XP). The result should be 0 but it returns -5.

Cascading LOV always returns first row in af:query

HI
JDEV 11.1.1.3.0
A strange thing is happening with my cascading LOV which is input text with LOV.
I have a read only table with a query section. I then also bring up any of the tables rows in a popup with single record view where the row is then in an af:form for inserting and updating.
Both the af:query and af:form have the cascaing LOV in them.
When testing the cascading LOV in the BC Browser it works fine. When I use it in the popup in the af:form record it works fine. But in the af:query section, no matter which row I choose in the LOV, it always returns the 1st row of the LOV back to my input text component.
Has anyone experienced this...any ideas?
Thanks,
Mario

Aha...and the above log message lead me to the solution!! :-)
The VO is based on an Oracle data dictionary view, DBA_TAB_COLUMNS. When you create the read only VO, by default it does not create any of the attributes as "key" attributes, because the oracle view has no primary key.
Setting owner, tableName and columnName as key attributes solved this issue, now my cascading LOV works in the BC Tester, af:query component and my af:form component.

Mario

SQL Query works in SQL Developer, but not always in MII

Hi all,
I encountered a strange behaviour with a query in MII 12.0.2. Maybe someone has a guess what happens.
I have created a SQL query which runs against Oracle 10g tables. I have tested the query using SQL Developer, and it throws a couple of lines, depending on the contents of the where clause.
Next I have copied the query to a MII SQL Query (FixedQuery). However, the output is empty most of the time, without showing any errors. After some testing I got the impression that older data are not displayed, but there is no time or date setting in MII.
As the SQL Developer always returns rows, I am unsure where to search for the error.
Regards
Michael

Michael,
I would imagine that you have sub-select statements in your FixedQuery, all which will fall subject to the RowCount property of the query template (SQL defaults to 100), which is issued through the driver and typically honored by the database when returning the data from your request.
Most of the native database query tools allow you to make unbound query requests with no limit on rows, which would probably account for the difference between SQL Developer and the query template.
For SQLServer it's ROWCOUNT: http://msdn.microsoft.com/en-us/library/ms188774.aspx
For Oracle it's ROWNUM: http://www.oracle.com/technology/oramag/oracle/06-sep/o56asktom.html
So the answer would be not to make the query template row count some rediculous number, but more appropriately refine the way that the database request is issued.
Regards,
Jeremy

Oracle Query Always return records

I want to have an Query In Which i always want to return one records regardless of exitence.
If no records exist ...it should appear as

0 0
if records exit it should appear as

manish 1

Hi,
You can do that with a UNION of your real query and something that selects the default values from dual. Just be sure the second part returns 0 rows when the real query returns anything.
WITH     real_query     AS
     SELECT     name
     ,     id
     FROM     table_x
     WHERE     ...
SELECT     *
FROM     real_query
UNION ALL
SELECT     '0'     AS name
,     0     AS id
FROM     dual
WHERE     NOT EXISTS (
                 SELECT 1
             FROM        real_query
;As always, be careful that the two prongs of the UNION have the same number and types of columns in the SELECT clause.

SQL Query (PL/SQL Function Body returning SQL query) doesn't return any row

I have a region with the following type:
SQL Query (PL/SQL Function Body returning SQL query).
In a search screen the users can enter different numbers, separated by an ENTER.
I want to check these numbers by replacing the ENTER, which is CHR(13) || CHR(10) I believe, with commas. And then I can use it like this: POD IN (<<text>>).
It's something like this:
If (:P30_POD Is Not Null) Then
v_where := v_where || v_condition || 'POD IN (''''''''||REPLACE(''' || :P30_POD || ''', CHR(13) || CHR(10), '','')||'''''''''')';
v_condition := ' AND ';
End If;
But the query doesn't return any rows.
I tried to reproduce it in Toad:
select * from asx_worklistitem
where
POD IN (''''||REPLACE('541449200000171813'||CHR(13) || CHR(10)||'541449206006341366', CHR(13) || CHR(10), ''',''')||'''')
==> This is the query that does't return any rows
select (''''||REPLACE('541449200000171813'||CHR(13) || CHR(10)||'541449206006341366', CHR(13) || CHR(10), ''',''')||'''')
from dual;
==> This returns '541449200000171813','541449206006341366'
select * from asx_worklistitem
where pod in ('541449200000171813','541449206006341366');
==> and when I copy/paste this in the above query, it does return my rows.
So why does my first query doesn't work?
Doe anyone have any idea?
Kind regards,
Geert

Thanks for the help.
I made it work, but via the following code:
If (:P30_POD Is Not Null) Then
v_pods := REPLACE(:P30_POD, CHR(13) || CHR(10));
v_where := v_where || v_condition || 'POD IN (';
v_counter := 1;
WHILE (v_counter < LENGTH(v_pods)) LOOP
v_pod := SUBSTR(v_pods, v_counter, 18);
IF (v_counter <> 1) THEN
v_where := v_where || ',';
END IF;
v_where := v_where || '''' || v_pod || '''';
v_counter := v_counter + 18;
END LOOP;
v_where := v_where || ')';
v_condition := ' AND ';
End If;But now I want to make an update of all the records that correspond to this search criteria. I can give in a status via a dropdownlist and that I want to update all the records that correspond to one of these POD's with that status.
For a region you can build an SQL query via PL/SQL, but for a process you only have a PL/SQL block. Is the only way to update all these records by making a loop and make an update for every POD that is specified.
Because I think this will have a lot of overhead.
I would like to make something like a multi row update in an updateable report, but I want to specify the status from somewhere else. Is this possible?

Bc4j:RowScope on a Master Detail page always returns 0 rows for detail

Hi,
I have a problem with a Master Detail page that is called from another page. The Master Detail page has two View Objects, Budgets and Budget Versions. These are linked properly in BC4J and when I use these VOs together I can navigate through the Budgets (master) and the Budget Versions (details) are populated correctly.
However, I want to navigate to this page from another page which lists all possible Budgets. I pass the key of the selected Budget to the Master Detail page and the correct Budget is displayed, BUT the Budget Versions are NOT displayed - I get 0 rows returned.
The mechanism I use to pass the selected Budget ID to my Master Detail page is:
<ctrl:property name="key">
<ctrl:selection name="ViewTable" key="key"/>
</ctrl:property>
My BC4J Registry is set up as follows:
<bc4j:registryDef>
<bc4j:rootAppModuleDef name="BudgetModule"
defFullName="BudgetPackage.BudgetPackageModule"
configName="BudgetPackageModuleLocal"
releaseMode="stateful">
<bc4j:viewObjectDef name="ItiBudgetsView1">
<bc4j:rowDef name="CurrentBudgetRow" usesCurrency="True">
<bc4j:propertyKey name="key"/>
</bc4j:rowDef>
</bc4j:viewObjectDef>
<bc4j:viewObjectDef name="ItiBudgetVersionsView2" rangeSize="15"/>
</bc4j:rootAppModuleDef>
</bc4j:registryDef>
I then use
<bc4j:rowScope name="CurrentBudgetRow">
to get the correct Budget row in my master VO. But this always returns 0 rows in my detail VO. If I comment out the rowScope element, I don't get the desired Budget row, but I do get the correct Budget Version rows displayed. Is the rowScope element on the Budget VO interfering with the Budget Version VO?
Hope this is not too confusing!!
Thanks,
Steve

Steve,
I tried to create a comparable set of two pages and initially ran into the same problem. I just realized that my issue (which I hope is yours too) is that the rootAppModule name was different across my two pages. This led to each page having its own application module instance, so the currency was different on each page.
By changing all of my pages to use the same application module name (in the registryDef, in the appModuleScope tags in the page, and in the findAppModule tags in the handlers), I resolved this problem.
My event handler to go to the master/detail page from the master page, FYI, looks like this:
<event name="details" >
   <bc4j:findRootAppModule name="MyApp" >
    
    <bc4j:findViewObject name="CustomersView1" >
     
     <bc4j:findRowByKey>
      <bc4j:keyBinding>
       <bc4j:selectionKey name="viewTable" key="key" />
      </bc4j:keyBinding>
     </bc4j:findRowByKey>
    </bc4j:findViewObject>
    <bc4j:executeQuery />
    <go name="OrdersByCustomer_View" redirect="true" />
   </bc4j:findRootAppModule>
</event>Hope this helps.

Select query on table rcv_lots_interface is always returning null

Hi ,
I need a help on the below issue.
The issue is after creating PO in Oracle 11i I receive it in MSCA application.
When we receive it at that point data gets inserted in the table " rcv_transactions_interface " and we have written a trigger on it.
From the trigger on table " rcv_transactions_interface " we are calling a package and in the package we have select query on "rcv_lots_interface."
But the select query is always returning null even though we are passing the correct "interface_transaction_id " and also after the "Receiving Transaction Processor" is executed i can see data in the table " RCV_LOT_TRANSACTIONS " for the same transaction.
Below is the sample code i am using.

Based on reviewing them the workarounds range from dropping the index to setting "_disable_function_based_index" to TRUE.Facinating. It seems to me that if you use the undocumented intitialization parameter you might just as well drop the FBIs too.
Another hazard of FBIs is the Law of Unintended Consequences. 2 years ago we tried to use one to speed up a query in a PL/SQL package. Worked OK for that purpose, but an unrelated loader on the affected table ran and rand but never finished until the FBI was dropped.

ViewObject with rows not based on a query

Hello,
I have an ViewObject with rows not based on a query. For example, if in activate method from my application module I insert a row, that row will not show when I test my app module. Please do not answer with a link for SRDemo ADF+BC as i've read it and didn't find any answers there.

Yes,thanks, I found that, but I don't know how to do a ViewLink that have as destination a viewobject like that. I get all rows from destination for any row from source. There is a way to do that?

Portal report - If rows returned are 1 greater than max,last row not shown

We are experiencing what appears to be a bug with reports developed from a locally built Provider in Portal...
If my "maximum rows to return" is set to 20, and my search returns 21 rows/results, the "next" button to navigate to the last row does not appear. Therefore, the last row is not returned to the user....
We have been able to duplicate this with any number... For example, if we set the "max rows to be returned" to 59, and our results come back with 60 rows, neither the "next" button or last row are returned...
Bug by chance?
Thanks in advance for any help offered....

Hi Varsha,
Please pay attention when you are requesting motnly period for
start date : 1st July 2008
end date : 1st july 2008
After saving the period is changed to
Start Date : 7/1/2008
End Date : 7/31/2008
When you are requesting weekly period for the same interval, after sving the dates are changed again, according
you settings of first day of the week. It it is Monday it could be as following
Start Date : 6/30/2008
End Date : 7/6/2008
So you are asking data for not quite the same period.
Do you have data for monthly period in that interval?

Flashback query on the v$transaction

Spatial Queries Not Always Producing Accurate Results

Hi,
Spatial queries are not always producing accurate results. Here are the issues. We would appreciate any clarification you could provide to resolve these issues.
1. When querying for points inside a polygon that is not an MBR (minimum bounded rectangle), some of the coordinates returned are not inside the polygon. It is as though the primary filter is working, but not the secondary filter when using sdo_relate. How can we validate that the spatial query using sdo_relate is using the secondary filter?
2. SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT returns true when validating geometries even though we find results that are invalid.
3. Illegal geodetic coordinates can be inserted into a table: latitude > 90.0, latitude < -90.0, longitude > 180.0 or longitude < -180.0.
4. Querying for coordinates outside the MBR for the world where illegal coordinates existed did NOT return any rows, yet there were coordinates of long, lat: 181,91.
The following are examples and information relating to the above-referenced points.
select * from USER_SDO_GEOM_METADATA
TABLE_NAME      COLUMN_NAME      DIMINFO(SDO_DIMNAME, SDO_LB, SDO_UB, SDO_TOLERANCE)      SRID
LASTKNOWNPOSITIONS      THE_GEOM SDO_DIM_ARRAY(SDO_DIM_ELEMENT('X', -180, 180, .05), SDO_DIM_ELEMENT('Y', -90, 90, .05))      8307
POSITIONS     THE_GEOM SDO_DIM_ARRAY(SDO_DIM_ELEMENT('X', -180, 180, .05), SDO_DIM_ELEMENT('Y', -90, 90, .05))      8307
Example 1: Query for coordinates inside NON-rectangular polygon includes points outside of polygon.
SELECT l.vesselid, l.latitude, l.longitude, TO_CHAR(l.observationtime,
'YYYY-MM-DD HH24:MI:SS') as obstime FROM lastknownpositions l where
SDO_RELATE(l.the_geom,SDO_GEOMETRY(2003, 8307, NULL,
SDO_ELEM_INFO_ARRAY(1, 1003, 1),
SDO_ORDINATE_ARRAY(-98.20268,18.05079,-57.30101,18.00705,-57.08229,
54.66061,-98.59638,32.87842,-98.20268,18.05079)),'mask=inside')='TRUE'
This query returns the following coordinates that are outside of the polygon:
vesselid : 1152 obstime : 2005-08-24 06:00:00 long : -82.1 lat : 45.3
vesselid : 3140 obstime : 2005-08-28 12:00:00 long : -80.6 lat : 44.6
vesselid : 1253 obstime : 2005-08-22 09:00:00 long : -80.0 lat : 45.3
Example 2a: Using SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT
Select areaid, the_geom,
SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT(the_geom, 0.005) from area where
areaid=24
ResultSet:

Hi Carol,
1) I think the results are correct. Note in a geodetic coordinate system adjacent points in a linestring or polygon are connected via geodesics. You are probably applying planar thinking to an ellipsoidal problem! I don't have time to do the full analysis right now, but a first guess is that is what is happening.
2) The query window seems to be valid. I don't think this is a problem.
3) Oracle will let you insert most anything into a table. In the index, it probably wraps. If you validate, I think the validation routines will tell you is is illegal if you use the signature with diminfo, where the coordinate system bounds are included in the validation.
4) Your query window is not valid. Your data is not valid. As the previous reply stated, you need to have valid data. If you think in terms of a geodetic coordinate system, you will realize that -180.0,-90.0 and 180.0,-90.0 are really the same point. Also, Oracle has a rule that polygon geometries cannot be greater than half the surface of the Earth.
Hope this helps.
