Explanation of Query

I need the explanation of the below query:
Want to know the use of the Decode function used along with Row_Number, OVER, Partition by, order by and CASE.
DECODE (ROW_NUMBER () OVER (PARTITION BY cust_xref.source_cust_id ORDER BY
CASE
WHEN best_calling_addr_id = cust_addr.addr_id THEN 1
WHEN (best_calling_addr_id <> cust_addr.addr_id AND incentive_addr_id = cust_addr.addr_id) THEN 2
WHEN (best_calling_addr_id <> cust_addr.addr_id AND incentive_addr_id <> cust_addr.addr_id
AND best_mailing_addr_id = cust_addr.addr_id ) THEN 3
WHEN (best_calling_addr_id = best_mailing_addr_id AND best_calling_addr_id = '--') THEN 4
ELSE 5
END,
(DECODE (cust_az_addr.txn_fg, 'U', 1, 'I', 2, 3)), cust_addr.publish_dt DESC), 1, 1, 0 ) AS addr_rank

Hi,
What about reading some oracle doc. about these functions
http://docs.oracle.com/cd/B19306_01/server.102/b14200/functions040.htm

Very Slow Query due to Bitmap Conversion

I have a strange problem with the performance of a spatial query. If I perform a 'SELECT non_geom_column FROM my_table WHERE complicated_join_query' the result comes back sub-second. However, when I replace the column selected with geometry and perform 'SELECT geom_column FROM my_table WHERE same_complicated_join_query' the response takes over a minute.
The issue is that in the second case, despite the identical where clause, the explain plan is significantly different. In the 'select geom_column' query there is a BITMAP CONVERSION (TO ROWIDS) which accounts for all of the extra time, where as in the 'select other_column' query that conversion is replaced with TABLE ACCESS (BY INDEX ROWID) which is near instant.
I have tried putting in some hints, although I do not have much experience with hints, and have also tried nesting the query in various sub-selects. Whatever I try I can not persuade the explain plan to drop the bitmap conversion when I select the geometry column. The full query and an explanation of that query are below. I have run out of things to try, so any help or suggestions at all would be much appreciated.
Regards,
Chris
Explanation and query
My application allows users to select geometries from a map image through clicking, dragging a box and various other means. The image is then refreshed - highlighting geometries based on the query with which I am having trouble. The user is then able to deselect any of those highlighted geometries, or append others with additional clicks or dragged selections.
If there are 2 (or any even number of) clicks within the same geometry then that geometry is deselected. Alternatively the geometry could have been selected through an intersection with a dragged box, and then clicked in to deselect - again an even number of selections. Any odd number of selections (i.e. selecting, deselecting, then selecting again) would result in the geometry being selected.
The application can not know if the multiple user clicks are in the same geometry, as it simply has an image to work with, so all it does is pass all the clicks so far to the database to deal with.
My query therefore does each spatial point or rectangle query in turn and then appends the unique key for the rows each returned to a list. After performing all of the queries it groups the list by the key and the groups with an odd total are 'selected'. To do this logic in a single where clause I have ended up with nested select statements that are joined with union all commands.
The query is therefore..
SELECT
--the below column (geometry) makes it very slow...replacing it with any non-spatial column takes less than 1/100 of the time - that is my problem!
geometry
FROM
my_table
WHERE
primary_key IN
SELECT primary_key FROM
SELECT primary_key FROM my_table WHERE
sdo_relate(geometry, mdsys.sdo_geometry(2003, 81989, NULL, sdo_elem_info_array(1, 1003, 3), sdo_ordinate_array( rectangle co-ords )), 'mask=anyinteract') = 'TRUE'
UNION ALL SELECT primary_key FROM my_table WHERE
sdo_relate(geometry, mdsys.sdo_geometry(2001, 81989, sdo_point_type( point co-ords , NULL), NULL, NULL), 'mask=anyinteract') = 'TRUE'
--potentially more 'union all select...' here
GROUP BY primary_key HAVING mod(count(*),2) = 1
AND
--the below is the bounding rectangle of the whole image to be returned
sdo_filter(geometry, mdsys.sdo_geometry(2003, 81989, NULL, sdo_elem_info_array(1, 1003, 3), sdo_ordinate_array( outer rectangle co-ords )), 'mask=anyinteract') = 'TRUE'

Hi
Thanks for the reply. After a lot more googling- it turns out this is a general Oracle problem and is not solely related to use of the GEOMETRY column. It seems that sometimes, the Oracle optimiser makes an arbitrary decision to do bitmap conversion. No amount of hints will get it to change its mind !
One person reported a similarly negative change after table statistic collection had run.
Why changing the columns being retrieved should change the execution path, I do not know.
We have a numeric primary key which is always set to a positive value. When I added "AND primary_key_column > 0" (a pretty pointless clause) the optimiser changed the way it works and we got it working fast again.

Index for "group by" statement.

Hi,
I have a statement directed at the GLPCP table.
It sums op the plan number in each month.
In ABAP it looks like this
SELECT ryear rprctr racct kostl ps_psp_pnr rfarea
         SUM( hsl01 ) SUM( hsl02 ) SUM( hsl03 )
         SUM( hsl04 ) SUM( hsl05 ) SUM( hsl06 )
         SUM( hsl07 ) SUM( hsl08 ) SUM( hsl09 )
         SUM( hsl10 ) SUM( hsl11 ) SUM( hsl12 )
         INTO TABLE e_t_data
         FROM glpcp
         WHERE kokrs   EQ '0020'
         AND   ryear   IN l_r_year
         AND   rldnr   EQ '8A'
         AND   rrcty   EQ '1'
         AND   rvers   EQ '010'
         AND   rbukrs EQ '0020'
         GROUP BY ryear rprctr racct kostl ps_psp_pnr rfarea.
I have created an index on KOKRS, RYEAR, RLDNR, RRCTY, RVERS, RBUKRS. To support the where statement.
This speeds up the process some but i believe that greater performance can be achieved.
I ran the expression through the SQL explain routine.
The path looks like this http://yfrog.com/jdexplainpathj
It came out with poor performance regarding the group by sentence.
Explanation of query block number: 1   step: 2
Query block type is SELECT
Performance appears to be bad
Method:
.          additional sorts needed
.          for the composite table (current result table)
.          the sorts are performed
.          - to meet an GROUP BY
.          unknown or no prefetch is used
How can i build an index to support the group by sentence.
Best Regards

Hi Hermann,
I can see why you are confused. It is hard to keep track with the changes.
I will sum up:
The abap statement.
SELECT ryear rprctr racct kostl ps_psp_pnr
         SUM( hsl01 ) SUM( hsl02 ) SUM( hsl03 )
         SUM( hsl04 ) SUM( hsl05 ) SUM( hsl06 )
         SUM( hsl07 ) SUM( hsl08 ) SUM( hsl09 )
         SUM( hsl10 ) SUM( hsl11 ) SUM( hsl12 )
         INTO TABLE it_glpcp
         FROM glpcp
         WHERE kokrs   EQ '0020'
         AND   ryear   IN l_r_year
         AND   rldnr   EQ '8A'
         AND   rrcty   EQ '1'
         AND   rvers   EQ '010'
         AND   rbukrs EQ '0020'
         GROUP BY rprctr racct kostl ps_psp_pnr ryear.
The SQL statement mad from the abap:
SELECT
"RYEAR" , "RPRCTR" , "RACCT" , "KOSTL" , "PS_PSP_PNR" ,"RFAREA" , SUM( "HSL01" ) , SUM( "HSL02" ) ,

Clamav not updating at expected times after update

I am running an intel xserve macosx server 10.4.10
my clamav was version 0.88.5
I updated clamav this morning to 0.91.1 using the tutorial from http://osx.topicdesk.com (I am still using clamscan and haven't made the changes to use clamd)
My clamav was set to update 8 times a day, ie every three hours.
However as of time of writing the system still hasn't checked for new updates.
It appears that /etc/freshclam.conf is set to 12 times a day (see below), whilst the SA GUI is still showing 8 times. Where does it get the frequency from?
Also /var/log/freshclam.log appears to show using clamav 0.91.1,
where clamscan --version
ClamAV 0.88.5/4107/Wed Aug 29 17:16:42 2007
Can someone tell me if I have made a config error. How do I get freshclam to start updating again at the required intervals?

If you followed my tutorial and used the support files referenced by it, then freshclam is set to update 3 times a day (which is more than enough).
If you are not happy with that, edit:

and change the value below "-c".
When done issue:
sudo launchctl unload /System/Library/LaunchDaemons/net.clamav.freshclam.plist
sudo launchctl load /System/Library/LaunchDaemons/net.clamav.freshclam.plist

Clamav end of life issue

So, will installing Xcode 3.1.4 give me the right gcc compiler and make things work? If so, do I need to delete the clamav-0.96 directory and start over? For what it's worth, the gcc file on my server is Developer/usr/bin/gcc-4.0.
I'm also wondering if updating to 10.5.8 would install an acceptable version of clamav. I'm a little hesitant to do that because everything has been running perfectly for quite a while now and I don't want to break it.
Any suggestions are greatly appreciated.
Thanks.
Keith

Okay, just updated to 10.5.8 successfully but still have the same clamav issue. Here's the latest freshclam log entry:

Should I go ahead with the separate clamav update? If so, is the topicdesk tutorial compatible with 10.5.8?
Another thing I've noticed is the log file problem with clamav. I've been getting this in the log for a couple of days:
Log size = 1048620, max = 1048576
LOGGING DISABLED (Maximal log file size exceeded).
Any fix for that. I've seen some solutions on other sites involving editing some files but it seems like there should be an easier way.
Thanks for your help.

Default; File Fault On in Yosemite?

I run a free Mac consultation service and recently I have had a few clients with Hard Drive issues on brand new MBA's. On investigation I found they had File Vault switched on. They were completely unaware of this and denied switching it on themselves. The issue here is that many people cant even remember their Admin Password much less a Recovery Key. It unnecessarily complicates repair, restore and login issues and causes problems with backups using third party Apps such as Carbon Copy Cloner and SuperDuper. I know everyone is a little paranoid these days but unless you are a spy or carrying top secret files internationally what the heck are you worried about.
I personally use a small encrypted .dmg Folder for the few details I would not want accessed. Otherwise who cares? I can always erase my laptop from Find My computer.
Why would Apple do this and if it's not Apple then it's the dealers and they have even less right to make those sorts of decisions for a user without proper explanation and query.

Got it! Now I understand; "But what's new in OS X Yosemite, is that more users are likely to enable FileVault than ever before—as at installation you have to consciously opt-out of having your hard drive encrypted, rather than opt-in."
Taken from this site (all credit to them)http://www.intego.com/mac-security-blog/yosemite-filevault/
So it would appear that you are correct. File Vault will be enabled unless you choose not to.
I can only say if I was given the option at my recent upgrades I must have pressed "no".
Can't say I remember that so it may be an inclusion of the most recent version 10.10.2 that behaves this way.
My guess is a lot of people would opt for this without thinking much about the possible complications. After all everybody wants security, right?
Setting it this way Apple seems to be saying, this is what we advise but the choice is up to you. I'd call that enticement.
As for devices bought already set up with Yosemite by a dealer for a purchaser my guess is they would advise enabling File Vault.
I love the heading "Take that FBI !!" Wow, emotive stuff for the paranoid among us.;)

How to determine estimated cost of dynamic SQL queries before execution?

Hi Performance Gurus,
Does anybody need know of a function module or program which can give me an estimated cost for a given SQL query. SQL query is a dynamic query and we need to know the estimated cost before we execute it.
Cheers
Jiby
Moderator message: subject corrected, in the future please use one that describes your problem better.
Edited by: Thomas Zloch on Aug 24, 2010 12:56 PM

Hi,
The mentioned function module does not give you the cost but the plan.
On DB2 e.g.
U Explanation of query block number: 1   step: 1
D Query block type is SELECT
S Performance appears to be bad
S No index is used. Sequential tablespace scan
E Method:
D           access new table.
D           data pages are read in advance
D           pure sequential prefetch is used
D           new table:
D                       SAPD8M.DD02L
D                       table space locked in mode: N
D           Accesstype: sequential tablespace scan.
I think there is some information that could be used as well (cost figure transformed to text)
S Performance appears to be bad
S No index is used. Sequential tablespace scan
But as already said: the whole requirement is quite strange...
I'm not aware of any other options, sorry.
Kind regards,
Hermann

Callconnector database goes down every hour

We have been running callconnector with no problems for the past 1 year, as of last week the database goes down pretty much hourly. The only change we made around the same time as this started was we changed admin passwords on all our servers / routers / switches due to a senior admin being let go from the company. Any help anyone can give would be great as we are a small non-profit company.
Our versions that we are running are CM Version 2.0.0.40 - Server Version 2.01.010
To get it back running I just have to click the database server button within configuration manager and it will work for another hour. The windows services don't seem to be affected only the services within the configuration manager. We are running this on a 2008 R2 VM environment.

I remembered it used to say 0.91, but now says 88.5, so I typed the following two lines in Terminal:
sudo /bin/launchctl unload -w /System/Library/LaunchDaemons/org.clamav.freshclam.plist
sudo /bin/launchctl load -w /System/Library/LaunchDaemons/net.clamav.freshclam.plist
Then I rebooted once more.
When it came back up, I checked the Server Admin Virus Update log and it now says:
Current working dir is /var/clamav
freshclam daemon 0.91.2 (OS: darwin8.10.0, ARCH: ppc, CPU: powerpc)

I assume this is what it is supposed to say now. ClamD (as of right now) is not taking up any resources, so maybe it will be better now. I will keep this topic posted of any changes.
Is there any recommended commercial products for OS X Server regarding anti-virus and anti-spam instead of using clamav? Also what command in Terminal will force a restart of clamd? I also saw a reference to a "rebuild of ClamAV" in another topic. How do you "rebuild" ClamAV?

Hi Alex,
Thanks for all your help it's just unfortunate where that linebreak fell in the tutorial!
missing space:
... --mandir=/usr/share/man--sysconfdir=/private/etc/spam/clamav/new ...
should be:
... --mandir=/usr/share/man --sysconfdir=/private/etc/spam/clamav/new ...
Issuing the previously mentioned commands now gives;

sudo launchctl list | grep clam

Freshclam.log is now showing the correct version but clamav.log and amavis.log still haven't changed.
You mentioned something about amavisd.conf is this why they logs are not updating and if so how do amavisd to log in the right place?
Thanks,
John

(with the maintenance recently, have they removed the search field or is that just me?)

The update virus database will not remain checked to run and as a result has not updated since February.
Ideas?

Any Explanations y this query is not ordering ?

SELECT dept_id, salary, job_id
FROM employees
ORDER BY
( SELECT dept_id
FROM departments
WHERE last_name='Abel');
Assumptions:
1. The inner subquery gives a value of 10 only.
2. There is no 10th column in the Table Employees.
3. There is only 1 employee in the department 10.
Output it gives :
It gives all that is there in the employees table(projected cols), However the first record is always from dept_id= 10, then it just displays without ordering.

yes you are partially correct. The subquery will return only 10 and not 1 or 5 or any other value.
I have an explanation to this query bt I'm not sure about it.
Oracle checks for semantics and syntax at compile time. So if everything is correct then only it submits the query for execution. Now when a subquery executes only then oracle knows there is no 10th col in the database so it is a runtime error.

Query Correction and Please Explan

Dear Experts
I have created a query to Sales Order ORDR and its Data from RDR1 and RDR1 and Connected it to Delievery ODLN. I want all the Sales Order irrespective of the Delievery is made or not. I some documents I am getting cartesian product. Please check the query and if can correct the mistake and Please do explain the your joining statement as the problem lies their.
Please find the query is below:
SELECT * FROM
ORDR T0 INNER JOIN RDR1 T1 ON T0.DocNum = T1.DocEntry
LEFT JOIN RDR2 T2 ON T0.DocEntry = T2.DocEntry
LEFT JOIN ODLN T3 ON T0.DocNum = T3.DocNum AND
T1.LineNum=T2.LineNum
Ill be grateful.
Faisal

Hi Faisal.......
Try this.....
SELECT * FROM
ODLN T0 LEFT JOIN RDR1 T1 ON T0.DocEntry = T1.TrgetEntry
LEFT JOIN RDR2 T2 ON T1.DocEntry = T2.DocEntry
Hope this will help you.....

Explanation For the query

Hi All,
Could anybody please explain me the following query.
How to display number value in words?
SQL> select sal, (to_char(to_date(sal,'j'), 'jsp')) from emp;
i know that j indicates Julion day.
i am unable to understand how to_date converts sal into date
Pls explain me in detail.
thanks in advance.
rampa

You've a decent instructor. The example is based on the SCOTT/TIGER sample schema.
Here's your code:
select sal, (to_char(to_date(sal,'j'), 'jsp')) from emp;Start inside the most nested parentheses:
SELECT TO_DATE(sal, 'J') FROM emp;Then convert that date to a string.
SELECT to_char(to_date(sal,'j'), 'jsp') FROM emp;Then add sal to the SELECT statement.
To understand each specific piece
TO_CHAR, TO_DATE, 'J', and 'JSP'go to the Oracle docs at http://tahiti.oracle.com and look them up.

I need a detailed explanation about this query!

Hey Guys,
I'm doing a course on distributed databases at uni. I have got this query but I am not 100% sure what is being executed first, the queries between brackets or outter ones.
What is the difference between semi-join and join queries?
what's meant by "WHERE EXISTS" clause?
what's the union do with the results?
SELECT C.COUNTRYNAME, C.CODE FROM "USER_HP_FULL"."COUNTRY" C
WHERE EXISTS(
SELECT 1 FROM (SELECT * FROM "USER1_HP_FULL"."ATHLETE1_REPLICA1"
UNION SELECT * FROM "USER2_HP_FULL"."ATHLETE2_REPLICA1"
UNION SELECT * FROM "USER3_HP_FULL"."ATHLETE3_REPLICA1") A
WHERE A.CCODE = C.CODE)
ORDER BY C.COUNTRYNAME;
Thank you!

Then you should
1. open a sql*plus command window
2. log on as a user with the correct privileges
3. set serveroutput on
4. set autotrace traceonly
5. execute the query
Examine the execution plan - it will show you what is being executed first. If you have questions post the plan using \ tags.
