Inner Join Condition For Database Tables in JDBC Adapter

Hi
Is there any restriction for Number of database tables to Write Inner join Condition in JDBC.
Thanks

Venkat,
No there is no restriction in Inner join. If your query executes perfectly in target Database then the same query will exceute perfectly while calling through XI.
Best regards,

More than one join condition for 2 tables in obiee

Hello,
I am using obiee 11g.
There are 2 tables tableA and tableB where the join condition is like (tableA.col1=tableB.col1) or (tableA.col1 is null and tableB.col1 is null)
where should i do these type of joins.
I tried putting in physcial layer->f(x) but giving error like here only columns an d opertaors are allowed.
Thanks

ok here it goes.
I have a tableA with columns col1(pk),col2 and other columns
I have tableB with columns col1(pk),col2..Only these 2 columns.
Now distinct tableA.col2 values are put in tableB.col2. For those distinct values i have put the tableB.col1 values.
Now tableA.col2 as well as tableB.col2 can be null beacuse there may be null values in tableA.col2.
Now in tableB i have added one more row which has col1 as value and col2 as null.
Now when in physical layer when i do tableA.col2=tableB.col2 i dont get the null values.
What i want is whenever the tableA.col2 and tableB.col2 is null then take tableB.col1 for those vales.
So when i query i do
select * from tableA,tableB where
((tableA.col2=tableB.col2) or (tableA.col2 is null and tableB.col2 is null))
What i want is when i do a join i should be able to give this OR condition in rpd thats it.
because when i do in where clause of content tab it goes like a AND condition and not OR.
Thanks

Populating SAP Database table using JDBC adapter

Hi Folks,
I have a requirement to populate a SAP database table say ZTABLE using XI. The Model is the table has to be populated through a file which will be processed by SAP XI. Basically this is a File to JDBC scenario. The database used is ORACLE. Kindly provide me some idea to go ahead.

I tried to place the MS access table in the shared folder of the Application server system but still it seems the table is not being populated.
did you check the log in your receiver channel? (/people/sameer.shadab/blog/2005/10/24/connecting-to-ms-access-using-receiver-jdbc-adapter-without-dsn)
The requirement is to update the tables directly as those are the custom tables.
i would still say that do not update SAP tables directly from XI/ PI.....this is not a standard architecture/ solution....

Inserting Multiple Rows into Database Table using JDBC Adapter - Efficiency

I need to insert multiple rows into a database table using the JDBC adapter (receiver).
I understand the traditional way of repeating the statement multiple times, each having its <access> element. However, I am just wondering whether this might be performance-inefficient, as it might insert records one by one.
Is there a way to ensure that the records are inserted into the table as a block, rather than record-by-record?

Hi Bhavesh/Kanwaljit,
If we have multiple ACCESS tags then what happens is that the connection to the database is made only once. But the data is inserted row by row.
Why i am saying this?
If we add the following in JDBC Adapter..logSQLStatement = true. Then incase of multiple inserts we can see that there are multiple
Insert into tablename(EMP_NAME,EMP_ID) VALUES('J','1000')
Insert into tablename(EMP_NAME,EMP_ID) VALUES('J','2000')
Doesnt this mean that rows are inserted one by one?
Correct me if i am wrong.
This does not mean that the transaction is not guaranted. Either all the rows will be inserted or rolled back.

Sumit

Inner joins Vs for all entries

Hi All,
Pls let me know
the differences b/w innerjoins and for all entries,,,,which is the best option and Y??
Thanks in Advance,
Bye

Hi!
INNER JOIN is used if we want to retrieve some data from more than one table.
FOR ALL ENTRIES is used if we want some data from a table based on some conditions of some other table.
Using several nested INNER JOIN statements can be inefficient and cause time out if the tables become too big in the future."
In ABAP, these joins are first split by the ABAP processor and then sent to the database, with the increase in DATA in production system, these joins tend to give way if your database keeps growing larger and larger.
You should rather use "FOR ALL ENTRIES IN" (Tabular conditions), which is a much efficient way as far as performance is concerned.

INNER JOIN with FOR ALL ENTRIES IN Performance ?

I am using following the following Select using Inner join with For All Entries in.
 SELECT kebeln kebelp kvbeln kvbelp
 FROM ekkn AS k INNER JOIN ekbe AS b ON kebeln = bebeln
 AND kebelp = bebelp
 INTO TABLE gi_purchase
 FOR ALL ENTRIES
 IN gi_sales
 WHERE k~mandt EQ sy-mandt
 AND k~vbeln EQ gi_sales-vbeln
 AND k~vbelp EQ gi_sales-posnr
 AND b~budat EQ p_date.
If i am not doing inner join then I will have to do 2 select with for all entries in on ekkn and ekbe tables and then compare them.
I want to know which one has better performance
Inner join with for all entries in
 or
2 Selects with for all entries in

the join is almost aways faster:

An Inner Join with for all entries should be done if you add this....
IF NOT gi_sales[] IS INITIAL.
SELECT k~ebeln k~ebelp k~vbeln k~vbelp
FROM ekkn AS k INNER JOIN ekbe AS b ON k~ebeln = b~ebeln
AND k~ebelp = b~ebelp
INTO TABLE gi_purchase
FOR ALL ENTRIES
IN gi_sales
WHERE k~mandt EQ sy-mandt
AND k~vbeln EQ gi_sales-vbeln
AND k~vbelp EQ gi_sales-posnr
AND b~budat EQ p_date.
ENDIF.
Also, while you use an index or the complete key for the SELECT, your not going to suffer from lack of performance -;)

Inner Join between two big tables

Hi There,
I have a situation where in which I have to write an inner join between two table of the order of (30k to 60 rows).
My query is as simple as,
select A.a,B.b from A ,B where A.a = B.b;
N.B: a and b are of type varchar
But the problem is it takes nearly 15 mins to run. Is there any better way of doing an inner join between such bigger tables?
Thanks,
Jose John.

Thank you all for your help.....Indexing works....:)

Join multi access database tables

Anybody knows how to join multi Access database tables
by using LAbview SQL tool kit? It seems Labview SQL does not support "JOIN" feature.
Thanks

But I still dont know how to join multiple tables.
I've tried:
SELECT pd.NAME, pp.PART_ID, pp.MATERIAL, pt.NAME
FROM PRODUCT pd INNER JOIN LOOKUP_PRODUCTPART pp
   ON pd.PRODUCT_ID=pp.PRODUCT_ID INNER JOIN PART pt
   ON pp.PART_ID=pt.PART_ID
But it doesn't work.
Hm.. the following (joinig two tables) works. It's shows that INNER JOIN works in LabVIEW:
SELECT pd.NAME, pp.PART_ID, pp.MATERIAL, pt.NAME
FROM PRODUCT pd INNER JOIN LOOKUP_PRODUCTPART pp
   ON pd.PRODUCT_ID=pp.PRODUCT_ID

best practise ... don't know ... it is allowed and o.k.
If possible you should of coourse to have no FOR ALL ENTRIES at all !
Joins, there is no general rule, check indexes etc.
The first SORT, I don't that it help for anything, use it together with the delete adjacent duplicates if you expect duplicates in the driver table.
o.k., it can help, if there is a loop afterwards and an append inside, because the new table itab1 is then sorted.

Temporary data carriers for Database tables

hi Gurus,
How can we find temporary Data Carriers for database tables. For eg. when we craete a BOM in CS01/CS02 the data first goes to RC29P structure and when system finishes it goes to STPO.
This is one example. how canw e find other structures and theirs corresponding Database Tables?
Any idea?
Regards

Hi Greg,
Those are the aggregated tables. If they are not filled with data although the Portal Activity Report is activated, you should check whether the aggregation finished successfully.
In the older SPs there were some problems that were fixed in later SPs of 7.0.
In order to have the latest version of Portal Activity report, you can check SAP note 1084379 - Portal Activity Report - Latest Version (SDA file).
You can compare the SP via the MANIFAST file, as it contains the version and SP number.
In order to troubleshoot problems in Activity Report, you can follow SAP note: 1690023 - Portal Activity Report - Component-specific Note
Some basic checks that you can do:
Run query on the raw data tables to check since when there is data in those tables:
select min(timestamphour) from SAP<SystemID>DB.WCR_WEBCNODESTAT;
If there is too much data from long time ago, then you should delete the old data, and leave only the new data (there is anyways retention time for the data to be kept).
If there is no data, then it means that the Portal Activity Report does not collect data, and not really activated (usually this is not the case).
The aggregation runs every top of the hour, so you can check in the default traces for an error during that time.
In most of the cases something went wrong while aggregating the data.
As a result the aggregation is not finished, so the transaction is not being committed, and the aggregated tables stay empty.
If there is a DuplicateKeyException in the trace, you can follow SAP note 1054145 - Duplicate Key Exception.
If you have any more questions, please don't hesitate to ask.
I hope this information helps,
Thanks & regards,
Michal Zilcha-Lang

Join conditions for the given tables

Hi,
I would like to join the below tables
FA_INVOICE_DETAILS_V FID
,AP_INVOICE_PAYMENT_HISTORY_V AIP
,PO_DISTRIBUTIONS_all PD
,AP_BATCHES_ALL AB
,PO_HEADERS_ALL POH
,PO_LINES_ALL POL
,FA_ADDITIONS_V FAA
can anyone give me the conditions to join the above tables. Its an urgent please suggest me
Thanks in advance

Only you can know how to join those tables. We don't know your business, your data, or your requirements.
If you would like us to help you, you need to provide the definitions of all the tables and which columns match between these tables. Then you have to tell us if you want inner joins, outer joins, theta joins, etc.
Please see the following link:

Inner Joins vs For All Entries - performance query

Hi All,
I'm a bit confused here... I see lots and lots (and lots...) of postings from people asking how to get data from multiple tables.
To me the immediate answer is to use joins in my select statement to reduce the database load but more and more I see people suggesting FOR ALL ENTRIES is better from a performance perspective.
Now, simple question time, which is more efficient in the real world when doing something like the following:- (this is a basic example but I'm sure you know what I mean.)
Select *
into table lt_sales_data
from vbap as vbap
inner join vbak as vbak
     on vbak~vbeln eq vbap~vbeln
where vbak~vbeln in so_vbeln.
or
Select *
into table lt_vbak_data
from vbak
where vbeln in so_vbeln.
if lt_vbak_data[] is not initial.
select *
into table lt_vbap_data
from vbap
for all entries in lt_vbak_data
where vbeln eq lt_vbak_data-vbeln.
endif.
Basically I want to know whether joins or for all entries is better from a database performance perspective.
I want to know why as well so please don't just post links, random cut and paste answers or one liners. I'm convinced for all entries is slower but am willing to be persuaded otherwise if someone can show me proof.
Thanks,
Gareth.

Thanks to all the opinions so far... You've backed up what I suspected although I maybe wasn't clear enough with my question and desired result. I was hoping someone could produce some hard and fast guidelines from SAP themselves dictating which is the better method. I know 10 years ago I was taught to use joins and to keep my database access to minimal levels, using keyed reads where applicable and using internal tables to filter data where I couldn't use key fields.
Gautham, I am aware of SM30 but that doesn't answer the general question I was asking. I've obviously used SM30 to run some comparisons but I was really hoping someone could give me a definitive answer based on hard facts or from attending some training at SAP recently. And no points for asking for them
Tamás, I agree with what you are saying about runing many comparisons - it appears to be dependant on any number of criteria which means each case may require different code. I've not managed to find a consistent comparison of the two methods that would lead me to use one method or the other...
Karan, thanks for your feelings but it doesn't really help me! Why/how does it retrieve the data faster than a join? Have you got testing/proof to back this up?
Raam, thanks for those links - they are interesting reads and seem to go through the same arguments I'm currently considering. Although I still don't have a definitie answer!
Amit, I understand exactly what yuo are saying about myths and urban legends That was my motivation for this post. To bo honest, it seems to me that a lot of the "newer" ABAP coders always go for FOR ALL ENTRIES but I wanted to know - is there a reason or do they all just cut and paste off SDN?! Are they all just scared of complex inner joins?! What would you all make of this Select statement for example? -
select afvc~arbid
            afko~aufnr
            aufk~objnr
            afko~plnnr

            afko~zaehl
            afpo~matnr
            makt~maktx
            afvc~vornr
            afvc~ltxa1
            afvu~aplzl

            afab~aplzl_vor
      into table lt_recipe_orders
      from afko as afko
     inner join aufk as aufk
        on aufk~aufnr eq afko~aufnr
     inner join afpo as afpo
        on afpo~aufnr eq afko~aufnr
     inner join makt as makt
        on makt~matnr eq afpo~matnr
     inner join afvc as afvc
        on afvc~aufpl eq afko~aufpl
     inner join afvu as afvu
        on afvu~aufpl eq afvc~aufpl
       and afvu~aplzl eq afvc~aplzl
     inner join afvv as afvv
        on afvv~aufpl eq afvu~aufpl
       and afvv~aplzl eq afvu~aplzl
      left outer join afab as afab
        on afab~aufpl_nch eq afvu~aufpl
       and afab~aplzl_nch eq afvu~aplzl
       for all entries in t_resources
     where afko~gltrs ge v_start_date
       and afko~gstrs le v_start_date
       and afko~plnty eq gc_task_list_type_2
       and afpo~dwerk eq v_werks
       and makt~spras eq sy-langu
       and afvc~arbid eq t_resources-objid.
Twinkal, I've always thought less DB hits is a better performing program too - the above example compares 2 db hits to 1... I don't have issues with complex joins because I've used them so long so can discount that problem but do agree that less DB hits is the ultimate goal. Providing of course the Selects you write are actually efficient in themselves.
Murthy, if you build your select statement correctly duplicate records can be avoided in most cases. How can you say a join statement will hit the database more when in my example there is 1 DB hit compared to 2 for a for all entries? And I'd love to know the reasoning behind never using a join on more than 2 tables?! Is that just an urban myth?!
Thomas, I've just been looking at some of Siegfried's posts and like what I am reading. As you say, using full keys via joins is essential.
