Package size in select query

Hi all,
Can any body help for how to use package size in select statemtent.
I want to seletc record in lot of 300 form 10k records.
And i am using 4.6c version and wnat to know this statement (package size) is there in 4.6c.
I know it is in 6.0.

Hi
Package size in SELECT statements
Package size can be used to retreive a spcific number of records at a time. This can be used if you
for example only want tofinish processing a limited amount of data at a time due to lack of memory.
The exampel below read 50 records at a time from VBAK into an internal table, and selects the
corresponding entries from vbap into an internal table. Then the two internal tables can be
processed, and the next 50 records from VBAk can be read. remeber to reinitialize tha tables before
the next read.
Note the usage of SELECT - ENDSELECT !
REPORT z_test                        .
TYPES:
BEGIN OF t_vbak,
vbeln LIKE vbak-vbeln,
erdat LIKE vbak-erdat,
END OF t_vbak,
BEGIN OF t_vbap,
posnr LIKE vbap-posnr,
matnr LIKE vbap-matnr,
meins LIKE vbap-meins,
END OF t_vbap,
BEGIN OF t_report,
vbeln LIKE vbak-vbeln,
erdat LIKE vbak-erdat,
posnr LIKE vbap-posnr,
matnr LIKE vbap-matnr,
meins LIKE vbap-meins,
END OF t_report.
DATA:
li_vbak   TYPE t_vbak OCCURS 0,
l_vbak    TYPE t_vbak,
li_vbap   TYPE t_vbap OCCURS 0,
l_vbap    TYPE t_vbap,
li_report TYPE t_report OCCURS 0,
l_report TYPE t_report.
START-OF-SELECTION.
SELECT vbeln erdat
FROM vbak
INTO TABLE li_vbak PACKAGE SIZE 50.
SELECT posnr matnr meins
FROM vbap
INTO TABLE li_vbap
FOR ALL ENTRIES IN li_vbak
WHERE vbeln = li_vbak-vbeln.
IF sy-subrc = 0.
Now you have the two internal tables li_vbak and liÆ_vbap filled with data.
Do something with the data - remember to reinitialize internal tables

Package size

hi experts,
please help in usage of package size in select query with where clouses
without for all enteries
regards
prashant

Hi Prashant,
Package size option in select query is useful in multiple cases:
- When the number of records accessed by the select query for the given where clause are very large and it may slow down the performance of the program. In this case package size option is used such that data is fetched in multiple hits.
- If the program is checking for a particular record from the database table having very large number of records without knowing the actual key. In this case package size can be used such that we can check for the existence of the required record after each fetching and can be exited from loop immediately after finding the record.
Thanks,
Sankar

Select command using package size

Hi all,
I have to fetch the same record comparing the records from two data base table for which i m using
select * from dbtab1 into table itab1 package size n
select * from dbtab2 into itab2
where field = itab1-field.
endselect.
the loop of select is executed once for second time its givin dump.
please help.
regards,
Gayatri

Hi Gayatri,
You can try following code:
DATA: l_itab1 LIKE itab1 OCCURS 0 WITH HEADER LINE.
Select first data for first select statement. Then select data for second select statement outside the ***** first select statement.
SELECT *
    FROM dbtab1
    INTO TABLE itab1
    PACKAGE SIZE n
ENDSELECT.
IF NOT itab1[] IS INITIAL.
   SORT itab1 by field.
   l_itab1[] = itab1[].
   SELECT *
   FOR ALL ENTRIES IN l_itab1
   FROM dbtab2
   INTO itab2
WHERE field = l_itab1-field.
ENDIF.
Hope this help you.
Regards,
Anil

Select query written on view giving dump

Hi All,
I have written the following query on COAS view in my code:
      SELECT aufnr bukrs INTO TABLE gt_aufnr
        FROM coas
          WHERE
                aufnr IN r_aufrm AND
                auart IN s_auart AND
                autyp = c_autyp_01 AND
                kokrs = c_kokrs_mbca.
When records in range r_aufrm are too many like 6000 or so it gives me a run time error on this query - DBIF_RSQL_INVALID_RSQL. Error description says size of select query is large.
Question : Is this bug coming because I am using the view. If i select the records on table AUFK (only table on which the view is created), will it rectify the problem?? I am asking this because it's in production and I cant make any change and test then and there.
Note: the range r_aufrm contains two types of records for AUFNR - 1. with sign GE and others with sign LE. So I cannot use for all entries. If I still can, please tell me how?
Thanks a looot!
Waiting for the response,
Navita

Thanks All!!
I think, this range limit has caused the problem. Range limit is 999 records.
Just one question I have. At runtime when I check the number of entries in r_aufrm in the query, I get 6000 entries. So, does it allow 6000 records to enter the range variable even if it has a limit of 999. Is it the case that, in select query only it will throw a dump if records in range exceed 999??
SELECT aufnr bukrs INTO TABLE gt_aufnr
FROM coas
WHERE
aufnr IN r_aufrm AND
auart IN s_auart AND
autyp = c_autyp_01 AND
kokrs = c_kokrs_mbca.
Please clear my doubt.
Thanks a lot for ur help!!!!

Select query on table rcv_lots_interface is always returning null

Hi ,
I need a help on the below issue.
The issue is after creating PO in Oracle 11i I receive it in MSCA application.
When we receive it at that point data gets inserted in the table " rcv_transactions_interface " and we have written a trigger on it.
From the trigger on table " rcv_transactions_interface " we are calling a package and in the package we have select query on "rcv_lots_interface."
But the select query is always returning null even though we are passing the correct "interface_transaction_id " and also after the "Receiving Transaction Processor" is executed i can see data in the table " RCV_LOT_TRANSACTIONS " for the same transaction.
Below is the sample code i am using.
CREATE OR REPLACE TRIGGER inv.RCV_TRAN_TRIGGER

Based on reviewing them the workarounds range from dropping the index to setting "_disable_function_based_index" to TRUE.Facinating. It seems to me that if you use the undocumented intitialization parameter you might just as well drop the FBIs too.
Another hazard of FBIs is the Law of Unintended Consequences. 2 years ago we tried to use one to speed up a query in a PL/SQL package. Worked OK for that purpose, but an unrelated loader on the affected table ran and rand but never finished until the FBI was dropped.

Error in select query with package size

Hi Experts,
I have an issue.
SELECT * FROM (w_tab-tablename) I
NTO CORRESPONDING FIELDS OF TABLE <lt_data> PACKAGE SIZE 10000.
Am splitting the table for every 10000 records,for first time the select query is successful.
But when it comes for the second 10000 records,its throwing the following dump.
"DBIF_RSQL_INVALID_CURSOR"
Help Appreciated

Hi,
 There are a few instances where you get this error.
 1) If you are debugging inside select ... endselect.
 2) You have written any of the below statements inside select ... endselect.
Please look at the dump .. you'll find the below ..

PACKAGE SIZE n in SELECT query

Hi,
When using PACKAGE SIZE n option with SELECT queries, how to determine the best/optimum value of n ? Especially when we use this for querying tables like EKPO, EKKO etc.
Regards,
Anand.

> When using PACKAGE SIZE n option with SELECT queries, how to determine the best/optimum value of n ?
The 'package size' option to the select specifies how many
rows are returned in one chunk.
According to ABAP-Doku, it is best to use it with an internal table:
DATA: itab TYPE STANDARD TABLE OF SCARR WITH NON-UNIQUE
DEFAULT KEY INITIAL SIZE 10.
FIELD-SYMBOLS: <FS> TYPE scarr.
SELECT * INTO TABLE itab PACKAGE SIZE 20 FROM scarr.
LOOP AT itab ASSIGNING <FS>.
WRITE: / <FS>-carrid, <FS>-carrname.
ENDLOOP.
ENDSELECT.
But, basically, your application's requirements determine
what's the best value for n.
If you don't want a lot of DB-access, you choose a high
value for n. If you don't want a lot of data in memory, you adjust it to a lower value.
You can also use the 'up to n rows' construct in the select to limit the number of rows fetched from the db.

Will it improve performance if PACKAGE SIZE added to a select query?

Hi Gurus
While doing the performance optimization I could see that in the code it is splitting the BKPF entries selected to a package of 500 and selecting from BSEG cluster table. In effect the remaining tables are also getting hit based on the no. of entries(packets) in the selected BKPF internal table.
Cant we use the package size 500 in the select statement instead of this spliting and hiting the tables in a do loop.
eg:-
 SELECT x v z
 FROM bseg
 APPENDING TABLE lt_bseg
 PACKAGE SIZE 500
 FOR ALL ENTRIES IN lt_coep
 WHERE bukrs = lt_coep-bukrs
 AND belnr = lt_coep-belnr_fi
 AND gjahr = lt_coep-gjahr.
When I read the keyword documentation I saw a note in that as " If the addition PACKAGE SIZE is specified together with FOR ALL ENTRIES, it is not passed to the database system, but is applied to the result set on the application server, after all selected rows have been read" I did not understand the meaning of this.
So I am confused whether I can go ahead with this approach or will go along with the already used BKPF split logic and selct from BSEG and other tables in DO loop.
Can you please help me << removed >>.
Thanks & Regards,
Shinimol.

Hi,
regarding your second doubt:
> Second doubt is on the note I saw in key word documentation. " If the addition PACKAGE SIZE is specified together with FOR ALL ENTRIES, it is not passed to the database system, but is applied to the result set on the application server, after all selected rows have been read. " I couldn't understnd this. When I debugged the select with F5 it was selecting 500 each till it reaches th end.
> So what does it mean, we can use this option or we should not use?
the FAE does your select in pieces and collects the result in the database interface in an inermediate buffer and
eliminates the duplicates there. AFTER this it gives you the number of rows back to your ABAP program that are specified with package size. It simply means that the package size addition has no effect on the memory consumptionfor the intermediate
buffer in the database interface.
Kind regards,
Hermann

Can we find the size of the query which is retrived in select operation??

Hi,
We run one select query and found that the query is retriving 953368 records(rows). Now is there any way to calculate how big is that query in terms of size.??
Could you pls suggest me.
Thanks,
Srini....

>

>
Yes but how many different tables are involved? How many columns? What are the datatypes of the columns?
If I run a query that returns one row it could have 900 columns defined as CHAR(4000), or one column defined as CHAR(1).
So row length is somewhere between 1 byte and 3.6MB times 1 million rows.
I'm guessing 1 million bytes minimum and 3.6GB on the high side.

How to determine package size dynamically for select - endselect statement in ABAP

Hi All,
I was using select- edselect with package size but i have hard coding the package size. Can any one tell me the the process to determine dynamic package size so that i can use in parallel processing.

Hi,
If you are looking to determine or set the value of package size dynamically then use below code for reference.
DATA: itab TYPE TABLE OF spfli,
       wa like LINE OF itab,
       n    TYPE i.
n = 10.
SELECT carrid connid
FROM   spfli
INTO   CORRESPONDING FIELDS OF TABLE itab
PACKAGE SIZE n.
   LOOP AT itab INTO wa.
     WRITE: / wa-carrid, wa-connid.
   ENDLOOP.
ENDSELECT.
If you are concerned about the performance then either use SELECT with OPEN CURSOR and CLOSE CURSOR.
Let me know if it helped?

Zuber

Thanks for your help
Marie

Hi marie,
1. When you do a select using package size
Its done when number of records is very high.
and we don't want to fetch all records,
IN ONE SHOT.
2. At that time, we fetch records in BUNCHES / PACKAGES.
3. Just copy paste to get a taste of it.
REPORT abc.
DATA : t001 LIKE TABLE OF t001 WITH HEADER LINE.
DATA : ctr TYPE i.
selection screen.

Performance issue after Upgrade from 4.7 to ECC 6.0 with a select query

Hi All,
There is a Performance issue after Upgrade from 4.7 to ECC 6.0 with a select query in a report painter.
This query is working fine when executed in 4.7 system where as it is running for more time in ECC6.0.
Select query is on the table COSP.
SELECT (FIELD_LIST)
        INTO CORRESPONDING FIELDS OF TABLE I_COSP PACKAGE SIZE 1000
        FROM COSP CLIENT SPECIFIED

   ENDLOOP.
ENDSELECT.
I have checked with the table indexes, they were same as in 4.7 system.
What can be the reson for the difference in execution time. How can this be reduced without adjusting the select query.
Thanks in advance for the responses.

Dedeepya.

Hi,
ohhhhh....... lots of problems in select query......this is not the way you should write it.
Some generic comments:
1. never use SELECT
                   endselect.
   SELECT
into table
   for all entries in table
where.
   use perform statment after this selection.
2. Do not use into corresponding fields. use exact structure type.
3. use proper sequence of fields in the where condition so that it helps table go according to indexes.
    e.g in your case
          sequence should be
LEDNR
OBJNR
GJAHR
WRTTP
VERSN
KSTAR
HRKFT
VRGNG
VBUND
PARGB
BEKNZ
TWAER
PERBL
sequence should be same as defined in table.
Always keep select query as simple as possible and perform all other calculations etc. afterwords.
I hope it helps.
Regards,
Pranaya

Hi,
1) RESULT_PACKAGE internal table contains any duplicate records or not bassed on the where condotion like below
2) Remove the into CORRESPONDING FIELDS OF table instead of that into table use.
refer the below code is
RESULT_PACKAGE1[] = RESULT_PACKAGE[].
sort RESULT_PACKAGE1 by /BIC/ZREB_SDAT AGREEMENT /BIC/ZLITEM1.
delete adjustant duplicate form RESULT_PACKAGE1 comparing /BIC/ZREB_SDAT AGREEMENT /BIC/ZLITEM1.
SELECT /BIC/ZSETLRUN AGREEMENT /BIC/ZREB_SDAT /BIC/ZLITEM1
from /BIC/PZREB_SDAT
into table i_tab
FOR ALL ENTRIES IN RESULT_PACKAGE1
where
/bic/ZREB_SDAT = RESULT_PACKAGE1-/BIC/ZREB_SDAT
AND
AGREEMENT = RESULT_PACKAGE1-AGREEMENT
AND /BIC/ZLITEM1 = RESULT_PACKAGE1-/BIC/ZLITEM1.
and one more thing your getting 10 million records so use package size in you select query.
Refer the following link also For All Entry for 1 Million Records
