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,
               I have a query regarding commit work.Below is the RFC that i have written
FUNCTION ZBAPI_CREATE.
*"*"Local Interface:
*" TABLES
*"      IT_ZABAP_RFC STRUCTURE ZBAPI_RFC_STR OPTIONAL
*"      RETURN STRUCTURE BAPIRET2 OPTIONAL
CALL FUNCTION 'ZBO_BAPI_CREATE'
TABLES
   IT_ZABAP_RFC       = IT_ZABAP_RFC
   RETURN             = return
Break-point.
DATA lt TYPE TABLE OF ZBAPI_RFC_STR_MAIN.
CALL FUNCTION 'ZBAPI_SEARCH_RANGE'
* EXPORTING
*   IS_STR        =
TABLES
   ET_TAB        = lt
*   RETURN        =
ENDFUNCTION.
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.
Regards,
Abhishek Bajpai

Hi Thomas,
                 Thanks for reply , i checked in ZTABLE ,before search RFC call data is not there but if i commit explicitly only then it is showing data in ZTABLE. Actually my requirement is different -
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

Fetch data from table and generate attachment than mail it.

Hello Experts,
From couple of day I am searching on Google for a better database procedure that will help me to get data from tables and generate attachment and mail it but i fail.
My Scenario is:
I have a query that will fetch almost 5000 records from database tables. Each record has almost 75 characters
select a.location_code,
 a.item_code,
 b.description item_desc,
 to_char(a.manufact_date,'ddMonyy')mfg,
 to_char((a.manufact_date + nvl(b.expiry_period,0)),'ddMonyy')expr,
 to_char((a.manufact_date + nvl(b.qurantine_period,0)),'ddMonyy')qrtn,
 round(nvl (b.qurantine_period, 0) - (sysdate - a.manufact_date)) days_elapsed,
 a.closing_balance_posted quantity
 from wms_stock_current_balance_v a, wms_item_setup_mast b
 where a.closing_balance > 0
 and a.item_code = b.item_code
 and a.loc_type in ('RACKING','PICKING','QUICKA','BUNDLED')
 and nvl(b.qurantine_period,0) > 0
 and round(nvl (b.qurantine_period, 0) - (sysdate - a.manufact_date)) <= 0
 order by a.item_code, a.location_code;
Sample data of above query is
LOCATION_CODE
ITEM_CODE
ITEM_DESC
MFG
Expiry
Quarantine
Days Elapse
Quantity

Fetch data from table(ET_) which is exporting parameter of function module

Hi,
I m new to ABAP programming.
I have to develop a smartform that has to be filled in with fields from few tables.
These tables have the naming convention ET_<XXX> (i.e. exporting parameter of function module).
I m not able to directly view its contents in se11 or use select query for it.
I have a report program which i can execute to view these parameter names.
Now, how do i fetch data from these parameters/tables and pass it from my driver program to smartform??
Someone pls guide me...
Thank You.

Hi,
I have done that using Field-Symbols.
Thanks,

Dear Team,

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...

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.

SURYA

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.
<Added code tags>
Can you suggest me anymore?
Regards,
SURYA

Fetch data from 3 tables (join vs select)
