Different results for the same query and same data ! (oracle 9i)

Hi,
This is a mystery for me. I've got on my database exactly the same data that my customer (exported schema). We both launch the same query (generated by the software that we sold him). This query has a criteria IN (SELECT MAX()...) to get only data from the last year.
The query gives 477 rows on my computer (correct answer), but no row on his! We have the same data! The only difference is the Oracle release : 9.2.0.6.0 for him, 9.2.0.1.0 for me.
If he executes the subquery alone, it gives the expected result.
If he replaces the MAX() in the subquery by the returned value (year 2016), he gets his 477 rows.
I've rewritten the query with a NOT EXISTS, and now all is fine. (Less efficient but it works).
I have no rational explication. Did I miss something ?
Thanks for any answer.
This is the query:
SELECT ...
FROM
CRA, GRA, ...
WHERE
/* subselect */
(CRA.COLLCOD, CRA.CRANEXE, CRA.CRANCODBUD, CRA.GRANNUM, CRA.CRANCOD1, CRA.CRANCOD2, CRA.CRANCOD3, CRA.CRANCOD4)
IN (
SELECT b.COLLCOD, MAX(cranexe), b.CRANCODBUD, b.GRANNUM, b.CRANCOD1, b.CRANCOD2, b.CRANCOD3, b.CRANCOD4
FROM CRA b
GROUP BY b.COLLCOD, b.CRANCODBUD, b.GRANNUM, b.CRANCOD1, b.CRANCOD2, b.CRANCOD3, b.CRANCOD4
AND... /* other filters and joins */

v9.2.0.1 was full of bugs. a lot of these bugs had to do with "incorrect results", typically associated with old stats or complex queries (certain types of subqueries were very likely to give wrong resutls, due to the way they were rewritten by the optimizer).
apply the 9.2.0.6 patch set

Different names for the 2.4 and 5 GHz networks are optional, but can be convenient for you to distinguish one from another. It's up to you.

PWA 2010 timesheet: 2 different colors for the rows "Actual " and "Planned

Hello,
To make timesheet easier to read and fill, is it possible to have 2 different colors for the rows “Actual “ and “Planned”?
Thanks,
soudha

Hello Soudha,
By default the timesheet grid shows the cells in white color. But if you have little coding skills or a developer at your end, you can try this using "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\LAYOUTS\JsGrid.js" java
script file.
You may have to modify it but I recommend to take a backup of the file and test in your test environment first.
Happy troubleshooting.....

Different results for the semantically the same queries

Hi,
I'm encountering a very odd problem. Before providing an XQuery code, I will ask on the abstract level. I have an XQuery module with my own functions defined. Then in my main query I import that module and execute one function from there. I get let's say 5 results. However if I copy that module into the body of the main query and execute the same function, I get 53 results. Can anybody tell me please, what might be wrong? Any pitfalls?
Vyacheslav

I narrowed down the query and the module code.
module:
module namespace mmt = "http://omdoc.org/ns";
declare namespace abox = "http://omdoc.org/abox";
declare function mmt:importsaux($graph as element()*, $tovisit as xs:string*, $visited as xs:string*) as xs:string* {
if (empty($tovisit))
then $visited
else let $to   := $tovisit[1],
            $from := $graph[@subject = $to]/@object[not(.=$visited)]
        return mmt:importsaux($graph, ($from, $tovisit[not(.=($to,$from))]), ($visited, $to))
};The main query:
import module namespace mmt = 'http://omdoc.org/ns' at 'http://alpha.tntbase.mathweb.org/repos/cds/db/mmt.xq';
declare namespace abox = "http://omdoc.org/abox";
declare function mmt:importsaux2($graph as element()*, $tovisit as xs:string*, $visited as xs:string*) as xs:string* {
if (empty($tovisit))
then $visited
else let $to   := $tovisit[1],
            $from := $graph[@subject = $to]/@object[not(.=$visited)]
        return mmt:importsaux2($graph, ($from, $tovisit[not(.=($to,$from))]), ($visited, $to))
(: change this to importsaux2 in order to change number of results :)
mmt:importsaux(collection('xml_content.dbxml')[dbxml:metadata('tnt:type')='mmt']/abox:mmtabox/
                             abox:relation[@predicate='HasOccurrenceOfInImport'],
                            "http://cds.omdoc.org/logics/first-order/model_theory/fol.omdoc?FOLMOD",
)So if I execute the query as it is, then I get 5 results. If I change the function name from the main query from importsaux to importsaux2, then I get 53 results. Those two functions are identical, but is in the module and another is in the query body. Don't know why the results are different.

Why am I getting different results for the same resolution but different Windows boxes, Win 7 and XP

I am running an .exe on two different windows boxes, one in Win 7 and one on XP. I set both for resolution 1024 x 768.
On Win 7 (laptop and old Dell desktop) I have a great looking app. On the WIn XP boxes all the fonts to large. THis doesn't make sense to me as all the PC's have the same resolution.
Has anyone run across this before?

The system fonts for XP and Vista/Win7 are different.

Process emthod in RT.jar producing different result for the same input

Hi All
I'm using the process method to manage my prcoess and Runtime to run a command, on onc pc it works fine but on the other it dosen't even though the input are the same, both pc are windows xp. Also there is a debug options which uses log4j, when that is set to true it adds more logging to the code and the code works fine if that is turned on (but there is not a different course of action if debug mode is on, just more logging i.e. if debug.enabled logInfo("more loggin").

Returning Different Results for the Same Search Value

I'm creating a word list and I'm using Lookup to find text entries in column D and return values from column A. I can manage one result based on the search criteria however I'm wondering if it's possible to return multiple entries from column A if multiple matches are found in column D:
As you can see I'm trying to use the formula =LOOKUP("Aggression",D,A) to find all the instances of "Aggression" in column D and return all the corresponding results from column A (audacious, barefaced, and depredation). Lookup however only returns the last match (depredation).

I wish you'd shown where your LOOKUP function is located and what you're trying to do with it. Are you going to be using these results in another function? Or are you simply wanting to display the results of your search?
If the latter, there's an elegant way to make this happen. Let's create a single-cell table on the same page, holding the word you're searching for. (Ideally, this could be a drop-down list -- and that can be made to dynamicly hold all the discrete values in column D -- but that's another discussion.) Let's call this table "Search".
Add a column (which can be hidden) to your original table. Let's insert this next to your column D, making it column E. Cell E2 contains =IF($D2=Search :: $A$1,TRUE,FALSE). Drag/copy that down the column. You'll now have a value of TRUE in this column for all the words you're looking for. Now click on the top of this column E and click "Show More Options".... and click on "Show rows that match the following". Set it to show where Column E is true. You now show only the words in which the "category" matches the search word.
Change the word in your Search table, and the display of your original table automatically adjusts.
The nice part is that the entire line is displayed so you can see definitions and contexts as well.

Different results for same query on different servers

1. database being converted from 7.3.4 to 9.2
2. query is executed on both servers
3. different results!
The tables and data are the same, and indexes are setup on new server. EXPLAIN PLAN was run on both but with (predictably) widely different results.
I know, not much detail here, but has anyone ever ran into anything like this?
Thanks,

Discussion:
Notice the repeating result for X,E,5,5,23,.... in the Oracle9i retrieval using CBO.
The execution of this query returned approximately four times the number of rows as
Oracle 7.3.4 using RBO. This is a function of how many "fours" there are in table3
that have matching "threes and fours" in table1. If you put a DISTINCT clause at the
very front of the query (SELECT DISTINCT one,two,three ....) then the result is
accurate and the same as Oracle 7.3.4. In one execution of this query, 27,000 rows
are expected to be returned, but the server returned over 1 million rows!
When RBO was used on Oracle9i, the results were identical to the ones on Oracle 7.3.4.

SDO_RELATE - EQUAL MASK - Different results on the same query

Hello.
I'm trying to find all spatial duplication in the point layer (using certain tolerance). That layer has q-tree spatial index and appropriate tolerance in the user_sdo_geom_metadata table (let's say 1 meter). I have SDO_VERSION=9.2.0.5.0.
To perform that I use SDO_RELATE operator with EQUAL mask (I know that actually I can use other operators but lets consider EQUAL):
SELECT /*+ ordered */t1.OBJECTID, /*+ ordered */t2.OBJECTID from points_table t1, points_table t2 WHERE t1.OBJECTID < t2.OBJECTID
AND sdo_relate (t2.shape, t1.shape, 'mask=EQUAL querytype = JOIN') = 'TRUE'
The problem is:
If I create Q-tree index using SDO_LEVEL=8 query takes 10 minutes and returns lets say 1000 dup events
If I create Q-tree index using SDO_LEVEL=10 query takes 20 seconds and returns lets say 996 dup events
I'm confusing about that - Why the results are depend from SDO_LEVEL? For me it is more important then performanse.
Those missed duplication events are really duplication events (point closer to each other than 1 meter) and SDO_DISTANSE for those particlar poins returns 0. It is correct, but SDO_RELATE monitors that those points are not equal.
So how can I rely on the SDO_RELATE function? What SDO_LEVEL need I use to get correct results? I choosed Q-tree indexes because of performance I didn't get success to get result using R-tree indexes on big datasets at all.
Regarding polylines:
I suppose that I can get similar problem and for polylines (Im also using same query to find dups polylines).
Sometimes SDO_RELATE finds polylines which ones are not really equal in the specified tolerance (1 meter). All cases that I saw it was simple segments which ones share only one vertex but the other ends are spatially disjoint more that 3 meters. Why SDO_RELATE finds such cases as EQUAL?
Thank you very much in advance.

Thank you Siva for advice.
I've tried R-tree indexes and got reasonable performance on the tables with ~20k rows.
But when I try to ran that query on the table (points) with 250k rows it takes forever :(.
1) Create index:
Create index nodes_idx on nodes(SHAPE) indextype is mdsys.spatial_index parameters ('LAYER_GTYPE=POINT initial=10m next=5m sdo_rtr_pctfree=10 pctincrease=0');
/* actually 'initial=10m next=5m sdo_rtr_pctfree=10 pctincrease=0' options only decreased slightly performance */
2) Execute query:
SELECT /*+ ordered */t1.OBJECTID, /*+ ordered */t2.OBJECTID
from nodes t1, nodes t2 WHERE t1.OBJECTID < t2.OBJECTID AND
sdo_relate (t2.shape, t1.shape, 'mask=EQUAL querytype = WINDOW') = 'TRUE'

Using different templates for the desktop and phone versions of the same blog

I have a site which was created in Adobe Muse and is hosted on Business Catalyst.
I have created both a desktop and a phone versions of the site.
I want to know how I can integrate the blogs that I currently have on the desktop site with the phone version that I just did, using different templates for the desktop and phone versions of the same blog. This is in order to ensure that visitors to the blogs on the website are directed to the templates that render correctly for the devices they are using.
My current approach has been to create both a desktop and phone versions of the blogs. The problem with this however, is that the dates are different and the comments are separated between the two blog versions!
I have also tried enabling mobile templates in BC, but still couldn't find a way to specify the mobile versions of the templates for the same blog?
To recap my problem, I basically need a solution where the same blog uses different templates for desktop and mobile (both templates use different navigation headings and menu styles)
Thanks.

There can be few reason for this, including page contents links or contents used in phone/tablet version.
Please provide the site url , also try to publish the site as a trial site in Business Catalyst with all layouts which would help to isolate the issue.
Thanks,
Sanjit

If I already have a particular app under one apple Id and I purchase the same app under a different Id for the same device, will it overwrite or replace the previous or will I have two of the same app on the same device??

If I already have a particular app under one apple Id and I purchase the same app under a different Id for the same device, will it overwrite or replace the previous or will I have two of the same app on the same device??
I'm asking because I purchased an app with an id that has been cancelled so I cannot update that particular app. I can purchase the app with my new id but I don't want to do so if its going to erase all the data I have with the previous purchase...

Figured it out. Thanks.

CBO generating different plans for the same data in similar Environments

Hi All
I have been trying to compare an SQL from 2 different but similar environments build of the same hardware specs .The issue I am facing is environment A, the query executes in less than 2 minutes with plan mostly showing full table scans and hash join whereas in environment B(problematic), it times out after 2 hours with an error of unable to extend table space . The statistics are up to date in both environments for both tables and indexes . System parameters are exactly similar(default oracle for except for multiblock_read_count ).
Both Environment have same db parameter for db_file_multiblock_read_count(16), optimizer(refer below),hash_area_size (131072),pga_aggregate_target(1G),db_block_size(8192) etc . SREADTIM, MREADTIM, CPUSPEED, MBRC are all null in aux_stats in both environment because workload was never collected i believe.
Attached is details about the SQL with table stats, SQL and index stats my main concern is CBO generating different plans for the similar data and statistics and same hardware and software specs. Is there any thing else I should consider .I generally see environment B being very slow and always plans tend to nested loops and index scan whereas what we really need is a sensible FTS in many cases. One of the very surprising thing is METER_CONFIG_HEADER below which has just 80 blocks of data is being asked for index scan.
show parameter optimizer
optimizer_dynamic_sampling integer 2
optimizer_features_enable string 10.2.0.4
optimizer_index_caching integer 0
optimizer_index_cost_adj integer 100
optimizer_mode string ALL_ROWS
optimizer_secure_view_merging boolean TRUE

Note: : There are slight difference in the no of records in the attached sheet.However, I wanted to tell that i have tested with exact same data and was getting similar results but I couldn't retain the data untill collecting the details in the attachment

Hi Paul,
I misread your question initially .The system stats are outdated in both ( same result as seen from aux_stats) .I am not a DBA and do not have access to gather system stats fresh.

Why do I get two different results from the same coefficients?

I am getting two different results from the Polynomial Evaluation function.
For the first one, I am getting the coefficients from a Polynomial Fit function. I feed the coefficients from the Fit function into the Poly Eval function and get the correct result of 12.8582 when I evaluate 49940.
For the second one, I create constant array of the SAME values that were returned from the Polynomial Fit function (i typed them in). However, I am getting an incorrect result of -120.7913 when I feed the constant array into the Poly Eval function when I evauate 49940.
How can this happen when I am using the same array values?
Attached is an image of what I am explaining.
Solved!

Hi Altran,
are you sure about using the "same" coefficients?
Did you compare them? Did you (atleast) set the display properties to 17 significant digits?
Please attach a VI instead of a picture...

Java-puzzlers...Why 2 different outputs for the same line

Here, why it is giving 2 different outputs for the same set of lines
Line-1 and Line-2 are both same.But giving 2 different results ???
/*java-puzzlers*/
public class Elementary {
    public static void main(String[] args) {
         System.out.println(12345 + 5432l); /*Line-1: Original statement- didn't modify*/
      System.out.println(12345 + 54321); /*Line-2: I wrote - I delete 12345 + 54321 and wrote the same thing again*/
}

Thank you for your co-operation.

Different results for the same query and same data ! (oracle 9i)
