Partial fields of Secondary index being used by the DB Optimizer

Hello,
I have written the following Query to select an std. SAP Index from GLPCA~1. However, when i run the SQL trace although the index is selected by the DB optimizer the results say that only 3 matching columns were used.
bold Index GLPCA~1. bold
KOKRS
RYEAR
RPRCTR
RVERS
RACCT
    SELECT rldnr
           rrcty
           rvers
           ryear
           rtcur
           rpmax
           rbukrs
           rprctr
           rfarea
           kokrs
           racct
           hslvt
           hsl01
           hsl02
           hsl03

           kslvt
           ksl01

           ksl08
           ksl09
           ksl10
           ksl11
           ksl12
           FROM glpct
           INTO TABLE i_glpct
           WHERE kokrs = 'BFS'
              AND ryear = p_gjahr
              AND rprctr IN r_prctr
              AND rvers = '000'
              AND racct IN r_acct.
Now i am not sure which of the above 3 fields of the where condition are being selected but probably KOKRS and RVERS are not being used by the optimizer.
Any pointers on how to make the optimizer utilize all 5 fields would be greatly appreciated.
Thanks,
Minhaj.

Materialized view not being used in the report

I have had a materialized view (MV) for a particular report. Recently, the report definition has changed little bit, so the existing MV is not being used by the report anymore. I copied the code Discoverer's SQL Inspection and recreated the materialized view. But still it is not working. Obviously, I am missing something at the database level. Does anyone have any idea? The database is 9i and Discoverer is 9.0.2. Thank you!

The SQL that you see from the Inspect SQL option will provide you with the SQL that Discoverer sends to the database. The database then may do a query rewrite to point to an available materialized view if available. This rewrite won't be seen from the inspect sql option. You need to check at the database level to verify if a query rewrite did in fact take place.
You may want to check the section titled "Query Rewrite with Materialized Views" from Ch1 - "Introduction to the Optimizer" in the Oracle9i Database Performance Tuning Guide and Reference, Release 2 (9.2), Part Number A96533-02, available at http://download-uk.oracle.com/docs/cd/B10501_01/server.920/a96533/optimops.htm#37287

Do you mean a trial account from .Mac? (DotMac)
"Get an AIM Screen name and set it to Display what you want as you set it up.
The Screen name can be whatever yu want but you can also set it to display something else as well."
I had thought about this, but it seems other people have already chosen the screen name "pinksharkmark" and virtually every variation of it I can think of. So that isn't an option for me. As for getting it to display something else as well, do you mean that if I were to get an AIM screen name like "CromulentCat" I could somehow log in to iChat under the AIM account "CromulentCat" yet get iChat to represent me to my Buddies as "PinkSharkMark"? Because I have to admit I don't see how that can be done. It appears as if iChat displays to anyone chatting with you precisely the account name you logged in under and nothing else. So if you logged in using a .Mac account, then you are displayed as "[email protected]" while if you logged in under an AIM account, you are displayed as "CromulentCat". But that's it that's all... there is no way to change CromulentCat to PinkSharkMark.
Thanks very much for taking the time to reply, though.

Another handy Firefox Add-on to add to your tool chest is called "Dust-Me Selectors."
http://www.sitepoint.com/dustmeselectors/
"It extracts all the selectors from all the stylesheets on the page you're viewing, then analyzes that page to see which of those selectors are not used. The data is then stored so that when testing subsequent pages, selectors can be crossed off the list as they're encountered.
You can test pages individually, or spider an entire site, and you'll end up with a profile of which selectors are not used anywhere."

How to know the Z tcodes being used by the company.

Hi Everyone,
Can you please tell me how do i know what are the Z tcodes being used by the company.My client is asking me to check all the Ztodes & tell them if there is any problem in them or not.
Regards,
Reah

Hello
You can find transaction code list in table TSTC.
All Z transaction code start with character Y or Z, you can query above table to get list of Z transaction codes.
Additionally you can use transaction code SE93 to view list of transaction Z transaction code and reports associated with these tcodes.
For second question you should get adequate knowledge transfer from existing IT or developer who developed these reports to be able to understand and test functionality of z tcodes.
Or
Please refer functional and technical documentation of these Z tcodes or reports.
Thanks!

CPU being used on the LIVE database server

Hi,
I'm seeing a lot of CPU being used on the LIVE database server, primarily by sessions running the following SQL :- As this is for audit log and a developer wrote it how can i optimize it or advise me pls
select * from ( select this_.ID as ID22_0_, this_.EVENT_TIME as EVENT2_22_0_, this_.AUDIT_LOG_EVENT_ID as AUDIT3_22_0_, this_.USER_ID as USER4_22_0_, this_.PUBLIC_OBJECT_ID as PUBLIC5_22_0_, this_.DESCRIPTION as DESCRIPT6_22_0_ from AUDIT_LOG this_ where this_.PUBLIC_OBJECT_ID=:1 order by this_.ID desc ) where rownum <= :2
thanks

It's a Top-N query and can be better written this way:
select this_.ID as ID22_0_, this_.EVENT_TIME as EVENT2_22_0_,
       this_.AUDIT_LOG_EVENT_ID as AUDIT3_22_0_,
       this_.USER_ID as USER4_22_0_, this_.PUBLIC_OBJECT_ID as PUBLIC5_22_0_,
       this_.DESCRIPTION as DESCRIPT6_22_0_
from (select AUDIT_LOG.*, row_number() over (Order by ID desc) rn
          from AUDIT_LOG
     where PUBLIC_OBJECT_ID=:1 ) this_
where rn <= :2I don't know if it will solve your issue...there are so many other variables...

This forum is dedicated to topics related to custom application development or deployment with Crystal Reports in .Net. This includes full versions of Crystal Reports as well as those versions of Crystal Reports bundled with Microsoft Visual Studio .Net.
As you do not want to do any coding, this query is in the wrong forum. However, in most versions of Crystal Reports, you can look up the database connection information by simply opening the report in the CR designer. Then go to the database menu and select "Set Datasource Location..."

My old apple ID is being used for the iCloud account. I need to change it to my current Apple ID, My old apple ID is being used for the iCloud account. I need to change it to my current Apple ID

My old Apple ID is being used for the iCloud account on my phone. I cannot change the account when I click on iCloud Settings. Please help!!

You will have to sign out from the iCloud preference pane and sign in with the new ID. Of course when you sign out all your iCloud data - email, calendars, contacts - will disappear from your Mac, assuming you have indeed been syncing them to the iCloud account you want to stop using. You can transfer the calendars and contacts manually, but you can't move the email addresses from one iCloud account to another.

Partial insert with secondary index

I'd like to use partial inserts (DB_DBT_PARTIAL).
However, I also need secondary indexes. Now when I insert partial data, the secondary index function is immediately called, but still I do not have enough data to calculate the secondary key. I tried to supply some app_data do the DBT, but it does not reach the secondary index function.
Is there any way I can use partial inserts together with secondary indexes?

When writing a partial record to the primary database, here's what we do:
1. Look up the existing record via get()
2. Using the existing record and the partial DBT, construct the new record
3. Pass that newly constructed record to the secondary key generation function
You don't need to do anything special, your callback will receive the full record, even though you passed us a partial DBT. If that's not the case, there's a bug in BDB and we'd need to see your code.
app_data is a private field, you should not try to use it or expect it to work predictably. In this situation, we're passing a brand new DBT to the callback function, not the DBT you gave us. That's why app_data is empty.

Using a byte[] as a secondary index's key within the Collection's API

I am using JE 4.1.7 and its Collections API. Overall I am very satisfied with the ease of using JE within our applications. (I need to know more about maintenance, however!) My problem is that I wanted a secondary index with a byte[] key. The key contains the 16 bytes of an MD5 hash. However, while the code compiles without error when it runs JE tell me
Exception in thread "main" java.lang.IllegalArgumentException: ONE_TO_ONE and MANY_TO_ONE keys must not have an array or Collection type: example.MyRecord.hash
See test code below. I read the docs again and found that the only "complex" formats that are acceptable are String and BigInteger. For now I am using String instead of byte[] but I would much rather use the smaller byte[]. Is it possible to trick JE into using the byte[]? (Which we know it is using internally.)

We have highly variable length data that we wish to use as keys. To avoid massive index sizes and slow key lookup we are using MD5 hashes (or something more collision resistant should we need it). (Note that I am making assumptions about key size and its relation to index size that may well inaccurate.)Thanks for explaining, that makes sense.
It would be the whole field. (I did consider using my own key data design using the @Persistent and @KeyField annotations to place the MD5 hash into two longs. I abandoned that effort because I assumed (again) that lookup with a custom key design would slower than the built-in String key implementation.)A composite key class with several long or int fields will not be slower than a single String field, and will probably result in a smaller key since the UTF-8 encoding is avoided. Since the byte array is fixed size (I didn't realize that earlier), this is the best approach.

Will indexes be used on the both sides of the join?

SELECT * FROM emp a, dept b WHERE a.dept_no = b.dept_no
Assume we have bitmap index on emp (dept_no) and we have binary index on dept (dept_no), will both the indexes be used for searching when equated?

I had looked the Explain plan, but it is taking only one index (index on dept (deptno)).
I tried giving hint for the other index, still no change in explain plan.
Will the other index be used while joining and not shown in explain plan?Care to show us your test case?
And your Oracle version?
Here's mine....

Change the Table being used insight the Procedure

Dear All,
I had 1 table "Customer" which is being used in 100 store procedures.
Now I rename that table to "Customer_Q".
Is there any method in SQL to repoint that table name insight All procs, without open my procedures?
If not, pls suggest any smart way..

Can you please throw some more light into it !!
Another way is this which will do replace behind the scene
DECLARE @Script varchar(max) = ''
SELECT @script = @script + REPLACE(definition,'CREATE PROC','ALTER PROC') + CHAR(13) + CHAR(10) + ' GO ' + CHAR(13) + CHAR(10)
FROM sys.sql_modules m
INNER JOIN sys.objects o
ON o.object_id = m.object_id
AND o.type = 'P'
WHERE definition like '% TableName %'
--double check script before execution
SELECT @script
--once happy uncomment below line and run full script again
--EXEC (@Script)
see this for more details
