Best way to query sap tables

hi everyone. i am new to data services, so here we go. we are using an sql2005 server for our end data repository. i am trying to create a temp table of sap po data. i have split the queries up so that query 1 is 2 sap tables, query 2 pulls in another sap table, etc. so that i only have one sap table, other then the first query, being queried at a time. it takes a really long time - i end up killing the job. is there a better way to pull sap data?
thanks - sandra.

Opinion needed on best way to map multiple table joins (of the same table)

Hi all
I have a query of the format:
select A.col1, B.col1,C.col1
FROM
MASTER_TABLE A, ATTRIBUTE_TABLE B, ATTRIBUTE_TABLE C
WHERE
A.key1 = B.key1 (+)
AND
A.key1 = C.key1(+)
AND
B.key2(+) = 100001
AND
C.key2(+) = 100002
As you can see, I am joining the master table to the attribute table MANY times over, (over 30 attributes in my actual query) and I am struggling to find the best way to map this efficiently as the comparison for script vs. mapping is 1:10 in execution time.
I would appreciate the opinion of experienced OWB users as to how they would tackle this in a mapping and to see if they use the same approach as I have done.
Many thanks
Adi

If I run this it takes less than a second in TOAD, when mapped in OWB it takes ages. 10:1 is a conservative estimate. In reality it takes 15-20 minutes. CSI_IEA_VALUES has 30 million rows CSI_ITEM_INSTANCES has 500,000 rows.
Hope that helps. I would love to know how others would tackle this query.

Best way to update custom table

Hello experts,
Iu2019m writing a report program and after pulling data from a custom table Iu2019m modifying certain fields within internal table and then eventually update custom table. The way Iu2019m updating custom table is working fine. However Iu2019m concern about performance issues because Iu2019m doing update on custom table within loop.
Here is my code for reference.
*&      Form update_contracts
      text
--> p1        text
<-- p2        text
FORM update_contracts .
Update record in an internal table first
loop at izsc_compliance into wa_zsc_compliance..
    wa_zsc_compliance-zapproval = c_accepted.
    wa_zsc_compliance-CHANGED_DT = sy-datum.
    wa_zsc_compliance-CHANGED_TM = sy-uzeit.
    wa_zsc_compliance-CHANGED_BY = sy-uname.
    modify izsc_compliance from wa_zsc_compliance index sy-tabix.
    write:/ sy-tabix, wa_zsc_compliance-vbeln_new, wa_zsc_compliance-zapproval.
    if p_test is initial.
      move wa_zsc_compliance to zsc_compliance.
      update zsc_compliance.
    endif..
endloop.
Write records to database
if p_test = 'X'.
    skip.
    write:/ 'Test mode'.
endif.
ENDFORM.                    " update_contracts
Iu2019m not certain if there is any better way by not doing update within loop and update custom table outside this loop.
Many thanks in advance.

Hi,
Yes, there is a better way to update the custom table. That will be more performance oriented and will be a much cleaner approach. As, I am not much aware of the custom table structure which you have in your program, the best way that I can suggest is to remove the update statement from that check. I guess you are checking against the mode - test or production. Once you have done the check, put the selected entries in an internal table which is same as database table. And then in a single command - a single array operation as it is commonly called, you can update the custom table.
Have a look at the following link
[Overwriting Several Lines Using an Internal Table|http://help.sap.com/saphelp_bw33/helpdata/en/fc/eb3a94358411d1829f0000e829fbfe/content.htm]
[Inserting or Changing Lines|http://help.sap.com/saphelp_bw33/helpdata/en/fc/eb3ac8358411d1829f0000e829fbfe/content.htm]
You can also scan the forum for multiple links and references and sample examples.
Hope this will help. The above approach will be much more performance oriented and will help to optimize. Also, check where exactly you are providing the locking feature if at applicable in your business functionality.
Regards,
Samantak.

Best way to check if table is empty or not

Hi. I had to check if a table was empty or not, and found different solutions.
One of them called my atention, I readed it was the best way to do it (some 'dual' trick from Steven Feuerstein, they say) :
SELECT 1 FROM DUAL WHERE EXISTS (SELECT 'X' FROM TABLE);
Plan
SELECT STATEMENT ALL_ROWSCost: 4 Cardinality: 1
     3 FILTER
          1 FAST DUAL Cost: 2 Cardinality: 1
          2 INDEX FAST FULL SCAN INDEX (UNIQUE) TABLE.UB_PK Cost: 2 Cardinality: 1
But doing some tests I found this query to have lower cost:
SELECT 1 FROM TABLE WHERE ROWNUM=1;
Plan
SELECT STATEMENT ALL_ROWSCost: 2 Cardinality: 1
     2 COUNT STOPKEY
          1 INDEX FAST FULL SCAN INDEX (UNIQUE) TABLE.UB_PK Cost: 2 Cardinality: 1
So, what about that dual table trick? Should I keep the 'select 1 where rownum=1' as best possible way?
I know it shouldn't matter much, but just wanna know what method works best for checking empty tables :)
Thanks.

As already mentioned, you cannot just base it on cost, as the cost is not specifically a good indicator of the amount of work that will need to be done, it's just an internal figure calculated for that query and isn't really that comparible across different queries.
If you're intending to see if there is data in a table because you want to know whether to query it or not, you are actually better to just try and query the data and capture the NO_DATA_FOUND exception and handle that. In that case it requires no effort or cost up front.

Best way to to display tables with a select drop down

I have created many SQL query report portlets, but I need a way for the users to select a specific acct nbr in a drop down list and then update a table on the same page. What is the best way to do this? I had created a Frame Driver, but I can not find a way to publish it to a page. Any ideas would be great, thanks.

Hi,
You can use a form based on table to do this. Build the form and publish it on the same page. The form can have a combination of various form items like textbox, textarea and drop down list etc. The form allows to query on the table and update the table.
Thanks,
Sharmila

What is the best way to learn SAP-ABAP

What is the best way to learn ABAP??
Stick to SAP press books and understand and learn theroitically
'or'
Move to ABAP programming and experiment all the things you have learn.
If both want to go hand in hand and if we want to do more practise, where can i find a source of abap programming questions (like codechef for java,c,c++..). Bcoz understanding new concepts require practise and to creating programs to practise is a really difficult.
Thnak you
Md Omar saleem

Hi,
Do the SAP course (BC400 - 5 days - it is a great course) and then practice practice practice.
The language itself is not difficult, but finding your way around the SAP system can be challenging.
Try to do real-life examples.
good luck!

Business rules to implement - BEST way - triggers and mutating table

I have the following table where it has Foreign Key defined on itself(self reference for parent_id column which can be null or valid site_id)
create table test_virtual_site
site_id number CONSTRAINT site_id_pk primary key,
parent_id number CONSTRAINT parent_site_id_unq UNIQUE ,
closed_date date default NULL ,
CONSTRAINT check_self_ref CHECK(parent_site_id <> site_id), --avoid self refernce
CONSTRAINT check_valid_site foreign key(parent_site_id) references test_virtual_site(site_id)
I have the following business rules to implement and my problem is related to their implementation
1)     A check should be made that Site_id specified as parent_id should not be a child of any other store (parent should have its parent_id column as NULL)
Site_id Parent_id
1
2 1
3 2 =>NOT VALID 2 is a child of another store
2)     Parent is not closed
Site_id Parent_id Closed_date
1 10-May-2005
3     1 =>NOT VALID 1 is a closed
3)
when parent store is closed - updated so at closed_date is not null
Want to set the parent_id as NULL for the child store.
OR
SET the closed_date for child store too same as the parent_store.
Example
Site_id Parent_id Closed_date
1
1 2
Update test_virtual_site
SET closed_date = sysdate
Where site_id = 1 ;
Through Trigger
Site_id Parent_id Closed_date
1     22-Mar-06
1 2 22-Mar-06
OR
Site_id Parent_id Closed_date

When I am trying to do the above mentioned through constraints I am running into mutating trigger problem. Can you please guide me what is the best way to handle the above-mentioned scenarios.
I am aware that I can avoid the 3rd problem using the following
-- - Initialize an array in the before statement trigger.
-- - Add the processed rowid to the array in the after row
-- trigger.
-- - In the after statement trigger: get each rowid from the
-- array and process it. When all rowids are processed, clear
-- the array.
BUT for 1 and 2 I need to look at the parent specified , the parent exists in the same table BUT I can not perform the lookup from the BEFORE INSERT ROW LEVEL trigger but I want to ensure at the row level , so if the parent store is closed or parent specifed itself is a child(not permissible) I want to rollback the insert RAISE_APPLICATION_ERROR.

What is the best way to learn SAP Java

Hi,
I would like to understand basic principles of SAP Java, to check how it is working, primarily J2EE components like JMS, WS, EJB, Persistence... As I'm ABAP and PI consultant, I see this as my next step, sure I'm not aiming to be experienced Java developer beacuse this would require much more time than I have now.
So far I read "Foundations of Java for ABAP Programmers" but I think that this is just a begining. I want to learn more stuff about SAP J2EE and J2SE is for me, let say, clear.
Also I start reading "Java Programming With The Sap Web Application Server" as my next book about SAP Java, but it is not quite that I don't like this book, it is somehow not interested for me.
So I would like to hear your suggestions what is the best way or the best approach to learn SAP Java. I see this as future help for one ABAP and PI consultant. Also I've done some Mapping developments for PI (SAX and DOM parser), so really think for me to know Java better it will be "bigger plus" for me.

It contains lot of practical examples which will keep you interested as well..
But you wil lhave to be very selective there on whaich topic you wish to kick start.........
For example there is one called :

Best way for an SAP newbie to work towards SAP BW + HCM

Hi, I am looking to be a part of a SAP HCM analytics group however an completely new to SAP. I would like to know what would be the best way to learn it. I am a Software engineer by profession however have not worked with SAP before. I have purchased a SAP Netwearver BI book from SAP press and have gone over various components of SAP BW, however not having a system to get my hands dirty learning is a challenge. Also from a functional perspective i have no experiance with HR and hence that is another challenge I am trying to work against. You help is appreciated.
Thanks

Ya as I was typing my message I realized I probably wasn't going to need the .net connector since I want a very generic service that basically just hands off the payment details to SAP.
As for what is going to consume the webservice ideally it would be independent of the type of SAP being used since potentially serveral different SAP installations would be able to access the service.
For the first version I am making the service be consumed by SAP Netweaver 7 Trial version. My company has a few clients using SAP lined up already to use the service once it is working but I don't know yet what version of SAP they each run.
If that is not possible I will either have to make a separate webservice for each type of SAP or else go another route and perhaps send the data as xml to SAP and let it import it on its own.
Right now I am playing around with the SOA manager, is that where the SAP PI is or am I on the wrong track.
I'll keep posting to this thread as I go along so someone in the future doing something similar can benefit.
I am trying to get the example at /people/wolfgang.bauer2/blog/2009/07/08/call-wcf-service-net-from-sap-with-usernametoken-and-ssl "Call WCF Service (.NET) from SAP with UsernameToken and SSL" going as a first step to understanding things.

Best way to clone a table?

Hi,
What is the best way to clone an existing table definition?
What I mean is, I want to do the following:
create table tab2 as
select * from tab1;
delete from tab2;
commit;
But clearly this involves copying all the data and then delete it. Is there a more efficient way?
Another alternative I could think of is:
create table tab2 as
select * from tab1 where rownum < 2;
delete from tab2;
commit;
This would copy only one row instead of all the rows in tab1. This is clearly much more efficient than the first approach, but I still don't like the idea of copying the data and deleting it.
I am sure there would be a "cleaner" way. Any ideas?
Thanks in advance,
Rajesh

Hi Justin,
My work involves generating statistics by running various queries. So, I have written a few procedures that generate the statistics and insert into certain tables. Usually before starting to generate a new round of stats, I take back up of the previously generated data like this.
Approach I:
alter table summary_tab rename to summary_tab_20th;
create table summary_tab as
select * from summary_tab_20th
where rownum < 2;
delete from summary_tab;
commit;
Of course, another alternative I have is the following:
Approach II:
create table summary_tab_20th as
select * from summary_tab;
delete from summary_tab;
commit;
But I thought this is inefficient when compared to Approach I because it copies ALL the data from summary_tab to summary_tab_20th and then deletes ALL the data from summary_tab.
However, one disadvantage with Approach I is that everytime I do this the stored procedure gets invalidated and I have to recompile it.
So, that is where I stand. If all this looks very dirty, please suggest how I can 'clean up' my process :-)
Thanks,
Rajesh

Best way to query data with varchar (max) cloumn.

whats the best way to select varchar(max) over a period?
Can anyone please help me on this?
Thanks,

I have joined three table and selected 15colmuns over a period of 6months it tooks 10sec .

That appears to be normal behavior for any RDBMS.
