Reading data from BSEG table with Non-key fields in where clause

Hi All,
I have to read data from BSEG table based on WBS element field (PROJK). As I'm not passing key fields to WHERE clause system couldnt run the select statement. Since BSEG is a cluster table I cant even create secondary index on PROJK field.
Could you please tell me, how to improve its performance.
Regards
Jaker.

SELECT bukrs
 belnr
 gjahr
 shkzg
 dmbtr
 hkont
 lifnr
 matnr
 werks
 menge
 meins
 ebeln
 FROM bseg
 INTO TABLE it_bseg
 PACKAGE SIZE 10
 FOR ALL ENTRIES IN it_final
 WHERE bukrs EQ it_final-bukrs
 AND belnr EQ it_final-belnr
 AND gjahr EQ it_final-gjahr
 AND buzei EQ it_final-buzei
 AND hkont EQ it_final-hkont
 AND werks IN s_werks.
By using package and fetch from BSEG table. gathering all other information to a final internal table.This will reduce the hit to database.And also try to put that data in hashed internal table which is it_bseg....then definetly improve the performance.

Data from two tables with no key fields

Hi Friends,
I want to retrieve data from mara and mseg tables,matnr from mara and menge from mseg but problem is there is no key fields
from these two tables how can i retrieve the data from these two tables?
regards,
bikash

Hi,
You need to have a common field between 2 tables if you want to put a join between them.
Or otherwise,
Find the check table of the primary keys of the tables.
Try to find the common fields from one of the check tables of the primary keys.
Example,
If you want to join tables A and B.
Both tables don't contain common fields.
A has primary key fields X and Y.
go to check table of X or Y.
Let check table of X is C.
check any field in C which are exist in table B.
Join tables A and C.
Based on this pick the data from B.

Reading Data from a Table With an Expert

Hi all - I'm trying to write an Expert in OWB that would read data from a table and create a new table based on that information. I have the table creation part down, but how can I read data from a table with an Expert? From what I've read, Experts only deal with metadata, and there is no mechanism in Experts to actually read data in the tables. Does OraTcl work in Experts? Has anyone ever came across this problem, and if so, how did you solve it? Thanks in advance for your time! - Don

Hi Don
Can also use Java and JDBC from within Tcl, see the routines in this file below, take modify or whatever;
http://blogs.oracle.com/warehousebuilder/ombora.tcl
source <dir>\ombora.tcl
set g_user scott
set g_upwd zzzzzz
set g_hostname localhost
set g_port 1521
set g_srvname ora111
oraconnect $g_user $g_upwd $g_hostname:$g_port:$g_srvname
oraselect "select * from emp" ""
As well as dumping the results to stdout (you probably want to comment that part out and change any other part you don't like), g_res is a ResultSet object you can use to do whatever.

Read data from cluster tables

Hi,
I met a problem.
How to read data from cluster tables using:
b2-key-pernr = 20.
b2-key-pabrj = 2006.
b2-key-pabrp = 09.
b2-key-cltyp = '1'.
import saldo from database pcl2(b2) id b2-key.
the problem is that the sy-subrc is always 4, could anyone help me?
thank you very much!

Hi,
Import and export to database is used in two programs and not in the same program.
ZPROGRAM1.
tables : indx.
Data : SALDO type i,
indxkey LIKE indx-srtfd VALUE 'ZAB1'.
indx-aedat = sy-datum.
indx-usera = sy-uname.
indx-pgmid = sy-repid.
EXPORT SALDO TO DATABASE indx(zc) ID indxkey.
In another program,
ZPROGRAM2.
tables : indx.
Data : SALDO type i,
indxkey LIKE indx-srtfd VALUE 'ZAB1'.
indx-aedat = sy-datum.
indx-usera = sy-uname.
indx-pgmid = sy-repid.
IMPORT SALDO FROM DATABASE indx(zc) ID indxkey.
Best regards,
Prashant

How to read Data from ZL table

Can someone give me function module or sample code to read data from ZL table in B2 cluster
Edited by: Saurabh Desai on Jan 13, 2010 9:13 PM

You wanted to extract data, ZL table to precise, from B2 cluster, is that right?
For this the snipped I gave you can be used.
First you need an inlcude with appropriate declarations
INCLUDE rpc2b201.       "-> here b2 structure, ZL table are declared
Now you provide key for the cluster which is what below does
b2-key-pernr = "ee number
b2-key-pabrj = "year to extract data for
b2-key-pabrp = "month to extract data for
b2-key-cltyp = 1.
Now all you need is to extract ZL table form B2 cluster
IMPORT zl   "get ZL table
FROM DATABASE pcl2(b2) "from cluster B2
ID b2-key.    "for this key
That's it. Now you have correct data in ZL table which you can process further.
Hope now it is clear.

Reading data from BSEG

Hi,
I never read data from Cluster table like BSEG, is there any precautions to be taken while reading data from it? as it contains voluminous data
please suggest.
regards,
Pra

Cluster Tables (BSEG,BSEC)
Should be accessed via primary key - very fast retrieval otherwise very slow
No secondary indexes
Select * is Ok because all columns retrieved anyway. Performing an operation on multiple rows is more efficient than single row operations. Therefore you still want to select into an internal table. If many rows are being selected into the internal table, you might still like to retrieve specific columns to cut down on the memory required.
Statistical SQL functions (SUM, AVG, MIN, MAX, etc) not supported

Cartesian of data from two tables with no matching columns

Hello,
I was wondering – what’s the best way to create a Cartesian of data from two tables with no matching columns in such a way, so that there will be only a single SQL query generated?
I am thinking about something like:
for $COUNTRY in ns0: COUNTRY ()
for $PROD in ns1:PROD()
return <Results>
<COUNTRY> {fn:data($COUNTRY/COUNTRY_NAME)} </COUNTRY>
<PROD> {fn:data($PROD/PROD_NAME)} </PROD>
</Results>
And the expected result is combination of all COUNTRY_NAMEs with all PROD_NAMEs.
What I’ve noticed when checking query plan is that DSP will execute two queries to have the results – one for COUNTRY_NAME and another one for PROD_NAME. Which in general results in not the best performance ;-)
What I’ve noticed also is that when I add something like:
where COUNTRY_NAME != PROD_NAME
everything is ok and there is only one query created (it's red in the Query plan, but still it's ok from my pov). Still it looks to me more like a workaround, not a real best approach. I may be wrong though...
So the question is – what’s the suggested approach for such queries?
Thanks,
Leszek
Edited by xnts at 11/19/2007 10:54 AM

Which in general results in not the best performanceI disagree. Only for two tables with very few rows, would a single sql statement give better performance.
Suppose there are 10,000 rows in each table - the cross-product will result in 100 million rows. Sounds like a bad idea. For this reason, DSP will not push a cross-product to a database. It will get the rows from each table in separate sql statements (retrieving only 20,000 rows) and then produce the cross-product itself.
If you want to execute sql with cross-products, you can create a sql-statement based dataservice. I recommend against doing so.

Reading Data from Internal Table

Hi,
Can anyone please tell me how to read data from Internal Tables in the Event Handler without using the Select statement OnInitialization?
Thanks,
Gaurav

Hi Siddhartha,
Can you tell me the problem in my code. I tried to work on the way you suggested. Though I have not finished with the coding, I just wanted to know whether I am going in the direction or not.
I have declared the the structure in Type Defination as
TYPES: BEGIN OF TEST_STRUC,
         BEGDA TYPE BEGDA,
         ENDDA TYPE ENDDA,
       END OF TEST_STRUC.
TYPES: TEST_TAB_TYPE TYPE TABLE OF TEST_STRUC.
In the Event Handler, I have added the following code on OnInputProcessing:
event handler for checking and processing user input and
for defining navigation
DATA TEST_INFO LIKE LINE OF TEST_TAB.
DATA: MYTAB6 TYPE TABLE OF PA0006,
      MYTAB6_WA LIKE LINE OF MYTAB6.
REFRESH TEST_TAB.
CLEAR TEST_INFO.
MYTAB6_WA-BEGDA = REQUEST->GET_FORM_FIELD( STARTDATE ).
MYTAB6_WA-ENDDA = REQUEST->GET_FORM_FIELD( ENDDATE ).
IF EVENT->NAME EQ 'button'
   AND EVENT->SERVER_EVENT EQ 'click'.
LOOP AT MYTAB6 INTO MYTAB6_WA.
    TEST_INFO-BEGDA = MYTAB6_WA-BEGDA.
    TEST_INFO-ENDDA = MYTAB6_WA-ENDDA.
ENDLOOP.
APPEND TEST_INFO TO TEST_TAB.
CLEAR TEST_INFO.
NAVIGATION->SET_PARAMETER( NAME = 'test_tab'
VALUE = 'begda' ).
NAVIGATION->SET_PARAMETER( NAME = 'test_tab'
VALUE = 'endda' ).
NAVIGATION->GOTO_PAGE( 'MyBSP2.htm').
ENDIF.
P.S. MyBSP2.htm is my next page.
Thanks,
Gaurav

Do I have to use lock when I am reading data from a table

Hi,
When i am reading data from a table , do I have to set a lock on that table .
Is it necessary for us to set the lock on a table when I am reading data from the table.
When I am updating the table , do I have to set a lock on the table ?
If yes, then what sort of lock-read lock,write lock or shared lock?
Regards,
Sushanth H.S.

check it out,
Lock objects are use in SAP to avoid the inconsistancy at the time of data is being insert/change into database.
SAP Provide three type of Lock objects.
- Read Lock(Shared Locked)
protects read access to an object. The read lock allows other transactions read access but not write access to
the locked area of the table
- Write Lock(exclusive lock)
protects write access to an object. The write lock allows other transactions neither read nor write access to
the locked area of the table.
- Enhanced write lock (exclusive lock without cumulating)
works like a write lock except that the enhanced write lock also protects from further accesses from the
same transaction.
You can create a lock on a object of SAP thorugh transaction SE11 and enter any meaningful name start with EZ Example EZTEST_LOCK.
Use: you can see in almost all transaction when you are open an object in Change mode SAP could not allow to any other user to open the same object in change mode.
Example: in HR when we are enter a personal number in master data maintainance screen SAP can't allow to any other user to use same personal number for changes.
Technicaly:
When you create a lock object System automatically creat two function module.
1. ENQUEUE_<Lockobject name>. to insert the object in a queue.
2. DEQUEUE_<Lockobject name>. To remove the object is being queued through above FM.
You have to use these function module in your program.
check this link for example.
http://help.sap.com/saphelp_nw04s/helpdata/en/cf/21eea5446011d189700000e8322d00/content.htm
tables:vbak.
call function 'ENQUEUE_EZLOCK3'
exporting

mandt = sy-mandt
vbeln = vbak-vbeln

_WAIT = ' '

endif.
Normally ABAPers will create the Lock objects, because we know when to lock and how to lock and where to lock the Object then after completing our updations we unlock the Objects in the Tables
http://help.sap.com/saphelp_nw04s/helpdata/en/cf/21eea5446011d189700000e8322d00/content.htm
purpose: If multiple user try to access a database object, inconsistency may occer. To avoid that inconsistency and to let multiple user give the accessibility of the database objects the locking mechanism is used.
Steps: first we create a loc object in se11 . Suppose for a table mara. It will create two functional module.:
1. enque_lockobject
1. deque_lockobject
before updating any table first we lock the table by calling enque_lockobject fm and then after updating we release the lock by deque_lockobject.
Select the radio button "Lock object"..
Give the name starts with EZ or EY..
Example: EYTEST
Press Create button..
Give the short description..
Example: Lock object for table ZTABLE..
In the tables tab..Give the table name..
Example: ZTABLE
Save and generate..
Your lock object is now created..You can see the LOCK MODULES..
In the menu ..GOTO -> LOCK MODULES..There you can see the ENQUEUE and DEQUEUE function

Select max date from a table with multiple records

I need help writing an SQL to select max date from a table with multiple records.
Here's the scenario. There are multiple SA_IDs repeated with various EFFDT (dates). I want to retrieve the most recent effective date so that the SA_ID is unique. Looks simple, but I can't figure this out. Please help.
SA_ID CHAR_TYPE_CD EFFDT CHAR_VAL
0000651005 BASE 15-AUG-07 YES
0000651005 BASE 13-NOV-09 NO
0010973671 BASE 20-MAR-08 YES
0010973671 BASE 18-JUN-10 NO

Hi,
Welcome to the forum!
Whenever you have a question, post a little sample data in a form that people can use to re-create the problem and test their ideas.
For example:
CREATE TABLE     table_x
(     sa_id          NUMBER (10)
,     char_type     VARCHAR2 (10)
,     effdt          DATE
,     char_val     VARCHAR2 (10)
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0000651005, 'BASE',    TO_DATE ('15-AUG-2007', 'DD-MON-YYYY'), 'YES');
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0000651005, 'BASE',    TO_DATE ('13-NOV-2009', 'DD-MON-YYYY'), 'NO');
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0010973671, 'BASE',    TO_DATE ('20-MAR-2008', 'DD-MON-YYYY'), 'YES');
INSERT INTO table_x (sa_id, char_type, effdt,                          char_val)
     VALUES     (0010973671, 'BASE',    TO_DATE ('18-JUN-2010', 'DD-MON-YYYY'), 'NO');
COMMIT;Also, post the results that you want from that data. I'm not certain, but I think you want these results:
`    SA_ID LAST_EFFD
    651005 13-NOV-09
10973671 18-JUN-10That is, the latest effdt for each distinct sa_id.
Here's how to get those results:
SELECT    sa_id
,         MAX (effdt)    AS last_effdt
FROM      table_x
GROUP BY sa_id
;

Read data from 2 tables.

Hello everyone,
I created a SQL database in phpMyAdmin. It contains 2 tables.
'Woninginformatie' and 'Makelaars'.
I use the next SQL query in my PHP file to read from the
database:
SELECT DISTINCT * FROM Woninginformatie
INNER JOIN Makelaars ON Woninginformatie.ID_mk =
Makelaars.ID_mk
WHERE Huiscode = $huiscode"
The query works correct and I get all the fields from both
tables. Anyway, in Flash I can only read out the information in the
table 'Woninginformatie'.
I use these kind of codes to read from the database:
eigendomssituatie =
gegevens.childNodes[0].childNodes[24].firstChild.nodeValue;
How can I also read data from the second table?

you can't read data from the 2nd table because because you
have a table issue, php issue or you can read data from the table
but are having trouble getting those data into flash? are you using
echo to return data to flash?
