Fetching data from a number of tables selected at runtime

Hi,
I have this application that stores user specific information on weekly basis. The application creates a new table every week and stores information in it on around 60 thousand users. The table structure is exactly the same for every week. Analytical reporting has to be done on this data which keeps on increasing every week. Views cannot be created as the reporting is dynamic and based on multiple tables which are in turn based on multiple time spans. For the same reason, the options to implement indexing and partitioning are ruled out. Is there an efficient way of doing it?
Thanking in anticipation,
Mehwish

Hi
What is your question?
Do you want to separate the data by week but you don't want to change the queries? Use partitions. What is the problem with them?

Authorization control when fetching data from PA OM tables

Hi all,
I want to know how to control DB level authorization using HR_READ_INFOTYPE and RP_READ_INFOTYPE. Taht is, i want to check whetehr the user who is executing a report is having read authorization for that infotype. If not, i should not fetch the data and the report should return error message?
Instead of authorization (std, custom) object, i want to control when fetching data from PA and OM tables in HR. How to achieve the same?

As EJP said, your query might have problem with the using clause. Post your query.
It gives an exception when I try to run the query, and I'm trying to fetch all columns not only 'taskid'
java.sql.SQLException: ORA-25154: column part of USING clause cannot have qualifier
Yes, with the exact sql query he posted. It gives that exception.I guess you are trying to fetch all the columns by using the above query which i posted. No you should not fetch all the columns. Because the rs will only the three columns.
Also, use 'as' with that query like,
select t1.taskid as t1_taskid, t2.taskid as t2_taskid ,t3.taskid as t3_taskid from...Edited by: Ram on Aug 23, 2011 6:20 PM

You need to perform some native SQL to fetch data. Before doing this connection must be exists b/w your R/3 and Oracle server.
Basis team will help you to have connection.
Check the connection name in the table DBCON.
Check the below code to handle native SQL.
SELECT SINGLE DBMS
           FROM DBCON
           INTO DBTYPE
           WHERE CON_NAME = DBS.
IF DBTYPE = 'ORA'.
    TRY.
      EXEC SQL.
        CONNECT TO :dbs
      ENDEXEC.

Select query taking too much time to fetch data from pool table a005

Dear all,
I am using 2 pool table a005 and a006 in my program. I am using select query to fetch data from these table. i.e. example is mentioned below.
select * from a005 into table t_a005 for all entries in it_itab
                   where vkorg in s_vkorg
                   and     matnr in s_matnr
                   and     aplp   in s_aplp
                   and     kmunh = it_itab-kmunh.
here i can't create index also as tables are pool table...If there is any solutions , than please help me for same..
Thanks ,

it would be helpful to know what other fields are in the internal table you are using for the FOR ALL ENTRIES.
In general, you should code the order of your fields in the select in the same order as they appear in the database. If you do not have the top key field, then the entire database is read. If it's large then it's going to take a lot of time. The more key fields from the beginning of the structure that you can supply at faster the retrieval.

SELECT is taking lot of time to fetch data from cluster table BSET

<Modified the subject line>
Hi experts,
I want to fetch data of some fields from bset table but it is taking a lot of time as the table is cluster table.
Can you please suggest me any other process to fetch data from cluster table. I am using native sql to fetch data.
Regards,
SURYA
Edited by: Suhas Saha on Jun 29, 2011 1:51 PM

Hi Subhas,
As per your suggestion I am now using normal SQL statement to select data from BSET but it is still taking much time.
My SQL statement is :
SELECT BELNR
              GJAHR
              BUZEI
              MWSKZ
              HWBAS
              KSCHL
              KNUMH FROM BSET INTO CORRESPONDING FIELDS OF TABLE IT_BSET
              FOR ALL ENTRIES IN IT_BKPF
              WHERE BELNR = IT_BKPF-BELNR
                  AND BUKRS = IT_BKPF-BUKRS.

Can you suggest me anymore?

SQL Select Performance - Approached to fetch data from big table

Hi
I just wanted to know view on different approached to fetch data from a table which has 40 billion records and which joined to another table which has 1 million record.
e.g.
I have two tables TableA and TableB
TableA has 40 Billion records has 6 columns
     TableA has partitions on Date
     TableA has required indexes
TableB has 1 Milluion record and has 10 columns
     Table A has indexes
Now I have written query like
select distinct TableA.column1,TableA.column2,TableB.columnA
FROM TableA join TableB
ON TableA.Column1=TableB.Column2
WHERE TableA.DateColumn between StartDate and EndDate
for a given date range it will fetch 5 billion of records which takes around 40 minutes.
I just wanted to know what all tuning approaches I can follow. What would be the best approach to make record retrieval faster in such a scenario.
Just wanted to know your vies/experience in such a scenario

Sufficiently large array fetchsize
and,
possibly using parallel query,
pop into my mind.
I would be interested though in the business requirement that asks for you to write a program that gets 5 billion (!) rows out of the database...

Select query taking 30 sec to fetch data from table containing BLOB column.

Hi Friends,<o:p></o:p>
Please help me...<o:p></o:p>
I have 15 columns in a table, in that 2 columns containing blob (images).<o:p></o:p>
More than 22 lakhs records are in a table.<o:p></o:p>
While i am try to fetch data from this table it nearly takes 25~30 sec to execute that query.<o:p></o:p>
When i deleted the two columns containing blob and i tried its executing fast .<o:p></o:p>
I should not change the table schema.<o:p></o:p>
Views also i created and indexes also there in a table.<o:p></o:p>
How can i improve the query execution speed?.<o:p></o:p>

And how large is the size of BLOB data in your table? If it's several giga bytes, then the time is simply required to read the amount of data from disk and to transfer it to the Client.

RFC fetching data from table which is not commited

Hi Experts,

here in first RFC call i am creating a record in ZTABLE , and then at break-point
i check the ZTABLE where it does not create any record because data is not commited into ZTABLE upto this point, but just after it i have written code for fetching data from ZTABLE but i am able to get this new record in lt.
Can anybody please explain that from where this serach RFC is providing data because inside serach i am simply selecting data from ZTABLE.

I have two RFCs 1. Create 2. Search , Now from web dynpro user will call first Create RFCs but at this point it should not insert record in ZTABLE and just after it user will call another search RFC and in this search he should be able to get these newly created records.
I want to have the functionality which a user gets when working with normal database front end like SQLPLus for Oracle. In these scenarios we see that whenever user does any insert or update the data sits in the table but still it is not committed. So there he fires Select query he sees the inserted data. But if he logs off from SQL PLUS and then logs in again, and fires Select query he does not see the data as it was not committed. I want a similiar functionalty in which if user inserts the data through Create RFC and fires the Select query through Search RFC then he can see the newly Created data also even though this data is not committed.
Although if i call create RFC in update task it will not update ZTABLE but in this situation , if user will call search RFC he will not be able to get newly created records.
So my requirement is that i should be able to get those records which are not commited in ZTABLE .If you have still any doubt regarding my question then please let me know.
Regards,
Abhishek

Generic datasource by function module to fetch data from multiple tables?

I'm writing a function module to fetch price, for generic datasource.
At first, extract test is OK. But InfoPackage never stop when loading data to PSA in BW.
And I find the example codes:
     OPEN CURSOR WITH HOLD S_CURSOR FOR
      SELECT (S_S_IF-T_FIELDS) FROM SFLIGHT
                               WHERE CARRID IN L_R_CARRID AND
                                     CONNID IN L_R_CONNID.
    ENDIF.                             "First data package ?
* Fetch records into interface table.
*   named E_T_'Name of extract structure'.
    FETCH NEXT CURSOR S_CURSOR
               APPENDING CORRESPONDING FIELDS
               OF TABLE E_T_DATA
               PACKAGE SIZE S_S_IF-MAXSIZE.
    IF SY-SUBRC <> 0.
      CLOSE CURSOR S_CURSOR.
      RAISE NO_MORE_DATA.
    ENDIF.
    S_COUNTER_DATAPAKID = S_COUNTER_DATAPAKID + 1.
ENDIF.
There using Cursor to fetch data package by package, and raise exception NO_MORE_DATA to stop the loading process.
Now I fetch data from multiple tables, I don't think I can use Cursor.
Then How can I handle this?
Thanks a lot.

Thanks
