Force use of an INDEX in ABAP
Is there a way to force the use of an index for a select statement in ABAP?
Is it possible ? Maybe with EXEC SQL . . .
Here find a trace
SELECT STATEMENT ( Estimated Costs = 28.747 , Estimated #Rows = 9 )
5 2 TABLE ACCESS BY INDEX ROWID EDIDC
( Estim. Costs = 28.747 , Estim. #Rows = 9 )
1 INDEX RANGE scan EDIDC~3
( Estim. Costs = 1.207 , Estim. #Rows = 269.667 )
As we can see sql optimizer choose index 3 but I though index 1 is better....

Hi Guys,
With reference to Indexes, the best way to use them is to check out all the fields that are available in the index and make your Select Query in such a way that :
(1) The fields in the index are present in your query.
(2) The fields are in the same order in the index and the query.
(3) OR conditions are avoided in the same line. E.g. Where ( matnr = '10000034' OR maktx = 'BB Prod.')
- Such statements are to be avoided.
If in a table there are many indexes SAP will decide by itself which index to use. This decision is based on a sampling percentage. This data is filled based on your configuration and can be viewed in ST05. In case the data has not been updated, you may find that SAP will use an index which you might not find suitable. Hence a situation may come up when you are required to force an index to be used in your SELECT query.

We’re seeing the following issue: sql - Can Oracle be forced to use the spatial index for sdo_filter in combination with an or clause? - Stack Overflow (posted by a colleague of mine) and are curious to know if this behaviour is due to a difference between standard and enterprise, or could we doing something else wrong in our DB config.?
We have also reproduced the issue on the following stacks:
Oracle SE One 11.2.0.3 (with Spatial enabled)
Redhat Linux 2.6.32-358.6.2.el6.x86_64 #1 SMP Thu May 16 20:59:36 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
11.2.0.3.0 Standard Edition and 11.2.0.4.0 Standard Edition (both with Spatial enabled)
Microsoft Windows Server 2003R2 Standard x64 Edition
However, the SQL works fine if we try it on Oracle 11.2.0.3.0 *Enterprise* Edition.
Any help or advice would be much appreciated.
Kindest Regards,
KevinIn my experience sdo_filter ALWAYS uses the spatial index, so that's not the problem. Since you did not provide the explain plans, we can't say for sure but I think yhu is right: Standard Edition can't use the bitmap operations, and thus it'll take longer to combine the results of the two queries (because the optimizer will surely split this OR up in two parts, then combine them).
BTW: when asking questions about queries here, it would be nice if you posted the queries here as well, so that we do not have to check another website in order to see what you are doing. Plus it will probably get you more answers, because not everyone can be bothered to click on that link. It would also have been nice if you had posted your own answer on the other post here as well, because my recommendation would have been to use union all - but since you already found that out for yourself my recommendation would have been a little late. -
Effect of Force use of non-existing index in program
Hi,
What is the Effect of Force use of non-existing index in program?
We have forced the use of a custom index in our program, i want to know the effect in the program if in the future this index will be deleted or removed from the database?
Thanks a lot!Hi Freishz,

Hints note, it is a hint not a command, are ignored by the optimizer if they are not
syntactically and/or semantically correct. An index hint pointing to a non-exisitng index
is semantically not correct -> will be ignored. (A normal costing with the available indexes
is done).

Hi Guys,
I have a problem with index. I created index on VBRK table with fieldsd VKORG & FKDAT and in selection query i am using only these two fields in where condition.
Most of the times the application is running perfectly. But some times it is running too long and giving a dump.
I checked with basis & dba team, they are saying it is running on different index when it is giving a dump i.e., it is executing on different index some times.
Can anybody give me a suggestion why it is taking a different index?
Or is there any chance to give a HINT in select statement in ABAP or specifically mension the index name in select statement?
regards,
shyleshHi,
this may occur when you are selecting on several different fields, not only those in the secondary index.
If too many fields are involved, the optimizer may not find the best index any more.
Possible reasons:
- table statistics are not up to date
- bug in the database software (Oracle 10 had some of those...)
- bad ABAP coding
Yes, you can use a hint to force the database to use a certain index, if you know what you're doing. But keep in mind that you are not database-independent any more with your code.
I have done this successfully with the BKPF table (90 million entries in our box...)

Query don't use the right index when using bind variables
Hi people !
I need some help because I have an issue with a query that don t use the right Indexes as it should
First of all, I have mainly three tables :
ORDER : Table that contains description for each Order (approximately 1 000 000 Records)
ORDER_MVTS : Table that contains the tasks made (called movements) to set up each Orders
with quantity of packages prepared for each product (approximately 10 000 000 Records)
PRODUCT : Tables that contains the products (approximately 50 000 Records)
When I launch the query with hard coded values, it brings back response very fast
because it uses the right index (ORDER_DHR_VALID) which represent the date and hour of the order
(with format 'DD/MM/YYYY HH24:MI:SS'). The selectivity for this index is good.
NB 1: I have to use the trick " >= Trunc(date) and < trunc(date) +1 " to filter on a simple date because
the index contains hour and minutes (I know it wasn't probably a bright idea at conception time).
NB 2: The index on ORDER_MVTS.PRODUCT_CODE is'nt discriminating enough because there is'nt enough different products.
It's the same for index on CUSTOMER_CODE and on MVT_TYPE so only the index on ORDER.DHR_VALID is good.
Here is the correct explain plan when I execute the query with hard coded values :
SELECT SUM(ORDER_MVTS.NB_PACKAGE)
FROM ORDER_MVTS, PRODUCT, ORDER
WHERE ORDER.DHR_VALID >= TRUNC(to_date('14/11/2008 10:04:56','DD/MM/YYYY HH24:MI:SS'))
AND ORDER.DHR_VALID < TRUNC(to_date('14/11/2008 10:04:56','DD/MM/YYYY HH24:MI:SS')) + 1
AND ORDER_MVTS.MVT_TYPE = 'DELIVERY'
AND PRODUCT.CODE = ORDER_MVTS.PRODUCT_CODE
AND ORDER_MVTS.ORDER_CODE = ORDER.CODE
AND ORDER.CUSTOMER_CODE = 'ADIDAS'
AND PRODUCT.CODE = 1234
Rows Row Source Operation
1 SORT AGGREGATE
2 NESTED LOOPS
4 NESTED LOOPS
2 INDEX UNIQUE SCAN (object id 378548) --> PRODUCT_PK
4 TABLE ACCESS BY INDEX ROWID ORDER
777 INDEX RANGE SCAN (object id 378119) --> ORDER_DHR_VALID
2 TABLE ACCESS BY INDEX ROWID ORDER_MVTS
30 INDEX RANGE SCAN (object id 377784) --> ORDER_MVTS_ORDER_FK
Now the problem is when the query is used in a Cursor with bind variables.
It seems like Oracle don't use index on ORDER.DHR_VALID because he can't figure out that he have
to actually filter on a short period of time (only one day).
So Oracle uses the index on ORDER_MVTS.PRODUCT_CODE which is'nt a bright idea (it takes 10 secondes instead of just one)
Here is the bad explain plan :
Rows Row Source Operation
1 SORT AGGREGATE
2 NESTED LOOPS
722 NESTED LOOPS
2 INDEX UNIQUE SCAN (object id 378548) --> PRODUCT_PK
722 TABLE ACCESS BY INDEX ROWID ORDER_MVTS
1790 INDEX RANGE SCAN (object id 377777) --> ORDER_MVTS_PRODUCT_FK
2 TABLE ACCESS BY INDEX ROWID ORDER
1442 INDEX UNIQUE SCAN (object id 378439) --> ORDER_PK
Now I have found two solutions to this problem :
1) using a Hint to force the use of index on ORDER.DHR_VALID (with /*+ INDEX(ORDER ORDER_DHR_VALID) */ )
2) Using Dynamic SQL and keeping the date hard coded (but not the other values except mvt_type)
For example :
QUERY :=
'SELECT SUM(ORDER_MVTS.NB_PACKAGE)
FROM ORDER_MVTS, PRODUCT, ORDER
WHERE ORDER.DHR_VALID >= TRUNC(TO_DATE('''||To_char(P_DTE_VAL,'DD/MM/YYYY')||''',''DD/MM/YYYY'')) '||
AND ORDER.DHR_VALID < TRUNC(TO_DATE('''||To_char(P_DTE_VAL,'DD/MM/YYYY')||''',''DD/MM/YYYY'')) + 1 '||
AND ORDER_MVTS.MVT_TYPE = 'DELIVERY'
AND PRODUCT.CODE = ORDER_MVTS.PRODUCT_CODE
AND ORDER_MVTS.ORDER_CODE = ORDER.CODE
AND ORDER.CUSTOMER_CODE = :CUSTOMER
AND PRODUCT.CODE = :CODE ';
These two solutions work but Number 1 is bad in theory because it uses a Hint
and Number 2 may be difficult to code.
So my question is : Does someone knows another solution to force the use of index ORDER_DHR_VALID that can be simple and reliable.
Thank you very much for support
Edited by: remaï on Apr 1, 2009 4:08 PMWhat version of oracle you have? CBO work is different in 9i and 10g.
Usually cost based optimizer do not want to use index for >< condition with binding variables because optimizer can not use statistic to determine selectivity, and by default selectivity of <> operators is low.
(As I remember '>' selectivity by default is 5%, you have two conditions > and <, therefore resulting selectivity will be 0.05*0.05=0.0025 as two independent events, but selectivity of other conditions
ORDER_MVTS.MVT_TYPE = 'DELIVERY' or ORDER.CUSTOMER_CODE = 'ADIDAS' looks much better for CBO)
The best solution I see is do not use binding variables. Actually your query looks as searching query, which executes not so often, therefore you will not have perfomance win along of skipping execution plan creation.

Unknown indexes in ABAP dictionary
Hi all,
can anyone help me with the procedure to handle unknown indexes in ABAP dictionary for a BW SAP_BW 350 Production system?
The list of some of the indexes are as follows :
/BI0/E0CCA_C11~P
/BI0/E0FIGL_C01~P
/BI0/E0OPA_C11~P
/BI0/E0PS_C04~P
/BIC/EIEFERC~P
Thanks a lot in advance ....Hello Varsha,
It seems that the index for these InfoProviders are missing.
Goto RSRV -> Elementary Test -> Database -> Database Indices of an InfoCube and Its Aggregates
It should be green. If its red there will be a correct button on the top just excute it
or You can use the following Function Module to check
RSDU_INFOCUBE_INDEXES_CHECK
To Repair

Query tuning and using the "better" index.
I have a database table with about 40,000 records in it. Using
a certain index first limits the number of rows to 11,000
records. Using a different index first (by disabling the other
index in the query) limits the number of rows to 2,500 records.
Using the explain plan, the rest of the query is parsed the same
way for both queries. What reasons can explain why when the
index that returns 11,000 records first runs faster than
the "better" index? I thought the whole idea behind query
tuning is to use the index that limits the data the most.It looks like Oracle likes the equality condition more than the greater than -less than combination (which you might like to recode as a BETWEEN condition for clarity).
There are a number of factors here.
i) Are the "test names" equally distributed? Do some test names appear with greater frequency than others? If so, collecting column statistics might cause the BATCH_2 index to be used for some test names, and not for others.
ii) Likewise, what is the distribution of cdates? How does the distribution of cdates vary by test name?
iii) You could force the use of the BATCH_6 index over the BATCH_2 by using an optimizer hint instead of dropping the BATCH_2 index ...
select /*+ index(batch batch_6) */ id, test, cdate
from batch
where test = 'Some test name'
and cdate >= &start date&
and cdate < &end date& + 1
... or even try prompting Oracle to use both indexes ...
select /*+ index(batch batch_6) index(batch batch_2) */ id, test, cdate
from batch
where test = 'Some test name'
and cdate >= &start date&
and cdate < &end date& + 1
... and test the response times, then chose to use the optimizer hint in your application
iv) You might like to replace the rather unselective BATCH_2 index with a BATCH_2_6 index on both test and cdate (in that order). That would probably give you an excellent result, and the BATCH_6 index can still be used to satisfy queries slective on cdate that are not selective on test (in very recent versions of Oracle the BATCH_2_6 index might be used for such an operation, and you could drop both BATCH_6 and BATCH_2)
Well, see if any of this helps. -
Problem in accessing mseg table using MSEG~M Index.
Hi Experts,
I am facing problem in accessing mseg table using MSEG~M Index. I used same sequence of fields and i tried with mandt field also. but it is not taking the Index and it is going for TImeout ABAP dump.

The above all code is not at all taking the index in Quality server .but in Development it is taking .In Quality server it is reading all datas without using the index and going Timeout ABAP dmup
Please, Suggest me some solutions.
Thanks in Advance.

Notes on using Object oriented concept in ABAP
Hi ,
I want somes notes on how to use Object oriented concept in ABAP.
Thanks in advance.
ChetanHi, this may help you
OOPs ABAP uses Classes and Interfaces which uses Methods and events.
If you have Java skills it is advantage for you.
There are Local classes as well as Global Classes.
Local classes we can work in SE38 straight away.
But mostly it is better to use the Global classes.
Global Classes or Interfaces are to be created in SE24.
SAP already given some predefined classes and Interfaces.
This OOPS concepts very useful for writing BADI's also.
So first create a class in SE 24.
Define attributes, Methods for that class.
Define parameters for that Method.
You can define event handlers also to handle the messages.
After creation in each method write the code.
Methods are similar to ABAP PERFORM -FORM statements.
After the creation of CLass and methods come to SE38 and create the program.
In the program create a object type ref to that class and with the help of that Object call the methods of that Class and display the data.
Example:
REPORT sapmz_hf_alv_grid .
Type pool for icons - used in the toolbar
TYPE-POOLS: icon.

Why is my query using the wrong index?
Hi SQL Tuning experts....
I'm running Oracle 11.2.0.2 EE on Solaris 10
I've just checked my top SQL statements in OEM and drilling down on the top query of the list, I decided to run SQL Advisor on the query.
Low and behold, it came back with a profile that gives me a 99.9% improvement.
When I compared the original plan to the new plan the only difference is that the SQL Advisor is using a different index.
Now, the dumb DBA question: why? why is Oracle picking the wrong index?
original plan
SELECT STATEMENT
COUNT STOPKEY
VIEW
SORT ORDER BY STOPKEY
TABLE ACCESS BY INDEX ROWID ARADMIN.T2179 TABLE
INDEX RANGE SCAN ARADMIN.T2179_C3 INDEXnew plan...
SELECT STATEMENT
COUNT STOPKEY
VIEW
SORT ORDER BY STOPKEY
TABLE ACCESS BY INDEX ROWID ARADMIN.T2179 TABLE
INDEX RANGE SCAN ARADMIN.T2179_C536870923 INDEXThe stats:
table has approx. 3.3Mil rows
table segment is approx. 15G (5G of it is reclaimable space, but probably not related)
table has fresh stats and indexes have been recently rebuilt
indexes in this discussion are both b-tree
the C3 column is number(15) with 2836897 distinct rows
the C536870923 columns is VARCHAR2(255) with 1080533 distinct values
Here is the actual query:
SELECT *
FROM (
SELECT T2179.C1,C536871040,C536871037,C536870944,C3,C536870918,C536870919,
C536870924,C536871048,C536871049,C536871050,C536870926,C536870925,
C536870916,C4,C536871275,C536871095,C536870913
FROM T2179
WHERE ((T2179.C536870923 = :"SYS_B_0") AND (T2179.C3 > :"SYS_B_1")) ORDER BY C1 DESC )
WHERE ROWNUM <= :"SYS_B_2"Obviously this is a good example of why we should use profiles. :-)

Lack of support for Google Chrome in forced-use email app
If this isn't resolved, I will cancel all Verizon services. Am seeing a consistent decline in VZ services:
1. ghosting and massive digital artifacts in HD programming, INCLUDING "Premium" channels
2. HD set top box quality is very poor
3. High pricing
4. VZ has terminated use of preferred browser (Chrome, which is SECURE and much faster than any others) in new forced-use email client.
As expected, VZ is acting once again as if they were "the phone company".
Not true.
Expect this post to be taken down quickly.Going to side with Justin here as well (and those of us who have been here for a while know, like ourselves, that he isn't a Verizon employee) ... the issues being described are indicative of a local inside wiring problem (poor cabling, loose connections, unterminated/noise introducing cable outlets, etc.). Since the TV is indicating problems, it's likely also interfering with the MoCA signal to the modem which would result in internet issues as well.
I can second my experience with Chrome as well ... it works just fine with Verizon webmail. Just tried it again to be sure.
If you are encountering problems, it would be helpful if you could be more specific. I suspect the you have an anti-virus / malware product that is probably set to block certain kinds of traffic (like Javascript, etc.) that is potentially interfering. The solution in such cases is to whitelist the Verizon site as a known location -- how to do that however is a function of your anti-virus/anti-malware product.
As for cost, I've been a customer for several years now. My rate went up by $10 once in that time and I ended up rebundling my STB's and essentially negating that increase. Compared to my cable provider -- who I continue to evaluate every year for cost/speed (while I like FiOS, I believe in fair competition and the best price / speed will always win my business) -- they are still the best deal for my money (don't get me wrong, cheaper or more bundle optons would be better!). YMMV. -
Unable to download OS X using Zapping PRAM index.
Unable to download OS X using Zapping PRAM index. Gives OS X Mavericks failed to download use the purchases page to try again - But cant see Mac app store icon as screen has completely gone grey
Since yesterday my Macbook Pro is not working - rather I cant see finder and upon booting, instead of any screen savers and icons displaying it is showing a balnk grey screen.
After reading some discussion and watching to some videos on You Tube, I managed to empty my Mac HD by traferring all the files to an external HD and then suing zapping PRAM keys, I got to a screen from where I am trying to download OS X to re install it.
However after some time it is giving error as 'OS X Mavericks failed to download use the purchases page to try again'.
But to access purchase page, I am unable to view Mac app stores application or icon.
Please help in fixing this issue.Hi there,
Mine is 2011.
I tried the suggestion you gave, but it didnt work.
However can someone help with clarification - mine is 2011 MBP and I reconk that it came with OS X Lion pre-installed and now with OS X utilities page, when I try to reinstall OSX it tries installing Mavericks and fails at certain stage.
When it fails I get pop-up message as 'OS X Mavericks failed to download use the purchases page to try again'
But I am unable to get App stores and go to purchases, as I dont see that option anywhere using OS X Utilities (which is the only way I am able to access my mac once I start)
So, Kindly help whether I need to get OS X Lion reinsalled first and then upgrade OS X Mavericks?
To do so, should I buy OS X Lion (as I dont think there is any back-up of OS available on my machine)?
Any suggestion will be much appreciated. -
Unknown indexes in ABAP dictionary for a BW SAP_BW 350 ?????????
Hi all,
can anyone help me with the procedure to handle unknown indexes in ABAP dictionary for a BW SAP_BW 350 Production system?
The list of some of the indexes are as follows :
/BI0/E0CCA_C11~P
/BI0/E0FIGL_C01~P
/BI0/E0OPA_C11~P
/BI0/E0PS_C04~P
/BIC/EIEFERC~P
Thanks a lot in advance ....
Madhavi RaneYou should be able to delete and recreate indexes from the infocube performance tab, RSRV or DB02. The bigger question is why these e fact table indexes are not being handled properly. I would try searching OSS Notes to see if yo ufind one relevant for your DB;
This older Notes provides some good background
