Long time taken to fetch data from Database Table
Moved to correct forum by moderator.
I had a requirement where i need to fetch records from table A912 for the matching entries in an internal table and satisfying some conditions.
The Internal Table(it_out) has 1,206 entries, while Databse table(A912) has 9,758,234 entries.
The Structure of Internal Table and Select Query are,
TYPES : BEGIN OF ty_a912,
matnr LIKE a912-matnr, "Material
kunwe LIKE a912-kunwe, "Ship-to party
datbi LIKE a912-datbi, "Validity end dt
datab LIKE a912-datab, "Validity start
knumh LIKE a912-knumh, "Cond rec no.
END OF ty_a912.
TYPES : BEGIN OF ty_out,
erdat LIKE vbak-erdat, "Date
vbeln LIKE vbak-vbeln, "Sales document
posnr LIKE vbap-posnr, "Item
kunnr LIKE vbpa-kunnr, "Customer
fkdat LIKE vbkd-fkdat, "Billing Date
ndc LIKE zndc-zndc, "EAN/UPC
matnr LIKE vbap-matnr, "Material
zr00p LIKE konv-kbetr, "ZR00 Price
zcarp LIKE konv-kbetr, "ZCAR Price
zrfcp LIKE konv-kbetr, "ZRFC Price
ctrnr TYPE char80, "Contract#
ctrnm TYPE char80, "Contract Name
a912p TYPE konv-kbetr,
END OF ty_out.
SELECT
matnr kunwe datbi datab knumh
FROM a912
INTO TABLE t_a912
FOR ALL ENTRIES IN t_out
WHERE matnr EQ t_out-matnr
AND kunwe EQ t_out-kunnr
AND datbi GE t_out-fkdat
AND datab LE t_out-fkdat.
It takes very long time to process this select query, is there any alternate way?
Please suggest some valid solution for this issue.

Hi,
can you give us an SQL trace in ST05? The SQL Trace (ST05) Quick and Easy
The FAE will be processed in a special way: see https://forums.sdn.sap.com/click.jspa?searchID=-1&messageID=6630311
If an index is NOT supported the FAE part will take forever...
if t_out is filled by another table you may go for a join? But again, index support is the key
bye

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 PMHi 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?

How to fetch data from database in javafx 2.2 table which is editable.
Dears!
I want to fetch data from database in javafx 2.2 tableformat with jdbc , which is also editable and i can add more records in this table also.
Can anybody help meI can vaguely recall some sort of JavaFX database connectivity feature, I'm not sure if it's valid anymore.The link is based on JavaFX Composer which only applied to NetBeans 6.9 and JavaFX 1.x (both of which are now dead techs).
There is a good chance you will have to write your own. There are several blogs describing other peoples' work. You could probably use them as a reference.Here is Narayan's basic [url http://blog.ngopal.com.np/2011/10/19/dyanmic-tableview-data-from-database/] tutorial for displaying data from a database in a TableView, you'll need to look elsewhere for the editing portion.
The [url http://docs.oracle.com/javafx/2/ui_controls/table-view.htm]JavaFX TableView tutorial gives info about how to handle edits in a TableView, but you will need to tie the updates back to the database yourself.
It is possible that [url http://www.javafxdata.org/]DataFX may provide some facilities to help support you. -

FETCHING DATA FROM A TABLE USING ARRAYLIST
how can we fetch data from database using arraylist????
Hi ,
This is the way to fetch data into 2d array , you can customize to fetch in array list .
we will assume that we have stm as Statement and rs as ResultSet
rs = stm.executeQuery("select * from emp");
int noOfColumns = rs.getMetaData.getColumnCount();
rs.last();
int noOfRows = rs.getRow;
rs.befpreFirst();
String [][] result = new String[noOfRows][noOfColumns];
for(int i = 0 ; i<noOfColumns;i++){
rs.next();
for(int y = 0;y<noOfColumns;y++){
result[i][y]=rs.getString(y+1);
rs.close; -
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 scenarioSufficiently 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... -
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

RameshHi Ramesh,
I have a query regarding accessing archived data through PBS.
I have archived SAP FI data ( Object FI_DOCUMNT) using SAP standard process through TCODE : SARA.
Now please tell me can I acees this archived data through the PBS add on FM : '/PBS/SELECT_INTO_TABLE'.
Do I need to do something else to access data archived through SAP standard process ot not ? If yes, then please tell me as I am not able to get the data using the above FM.
The call to the above FM is as follows :

How can we improve the performance while fetching data from RESB table.
Hi All,
Can any bosy suggest me the right way to improve the performance while fetching data from RESB table. Below is the select statement.
SELECT aufnr posnr roms1 roanz
INTO (itab-aufnr, itab-pposnr, itab-roms1, itab-roanz)
FROM resb
WHERE kdauf = p_vbeln
AND ablad = itab-sposnr+2.
Here I am using 'KDAUF' & 'ABLAD' in condition. Can we use secondary index for improving the performance in this case.
Regards,
HimanshuHi ,
Declare intenal table with only those four fields.
and try the beloe code....
SELECT aufnr posnr roms1 roanz
INTO table itab
FROM resb
WHERE kdauf = p_vbeln
AND ablad = itab-sposnr+2.
yes, you can also use secondary index for improving the performance in this case.

Drop Down list in table with data from database table
Hi,
I have created an interactive form in WD ABAP.
In Context tab I have created the nodes as follows:
ZSOHEADER node with cardinality 1..1
|-> MATERIAL node with cardinality 0..n. Under MATERIAL node there are 2 attrib. MAKTX and MATNR.
I am fetching data from MARA table into an internal table IT_MARA.
The node MATERIAL is bound to internal table IT_MARA.
I have created a table with property ' Body rows vary depending on data ' .
I have only one row in table. The first cell of the row is a drop down field.
I have bind the field to the node MATERIAL->DATA->MAKTX.
Now the issue is even though I have created only one row in my table, in preview it is creating as many rows in the table as the no.of records in the internal table.
I want only one row with the drop down list containing all values of the internal table.
Kindly suggest what to do.
Regards,
VinodHi,
In the WebDynpro Context, in the main node create another node like A1 with cardinality 0..n and in this node create attributes TEXT and VALUE.
Now goto method and in that method using code wizard read the node A1.
And use the below code snippet sample in your program, i.e. code this under respective method of the webdynpro.
*Declare the TYPES
TYPES : BEGIN OF TY_TABLE,
TEXT TYPE SOMETYPE,
VALUE TYPE SOMETYPE,
END OF TY_UOM.
*Define Internal Table and work area.
DATA : IT_TABLE TYPE STANDARD TABLE OF TY_TABLE INITIAL SIZE 0,
WA_TABLE TYPE TY_TABLE.
SELECT TEXT VALUE FROM TABLENAME INTO TABLE IT_TABLE.
lr_node_info->bind_table( IT_TABLE ).
And in the Adobe Form Layout
Go to Menu of the Adobe LiveCycle Designer:
Tools>Options..>DataBinding
In that window you just check the Show Dynamic properties Check Box.
Now for the Drop Down go the binding tab in object palette and click on the list items and there specify the Internal Table and specify the text as the internal table text field and value as internal table value field.
OR
From the WebDynpro Native Library Palette use the Value Help Drop Down and in object pallette goto binding tab and provide the form interface binding. Before this in the WebDynpro goto Context and for the particular field under the properties provide the search help as dictionary search help and specify the name of the dictionary search help.
OR
We have another method of setting the Text and Value to the DDL directly in the WebDynpro by coding in the methods, I dont have much knowledge on this.

Hey guys how to fetch data from db table using subroutine
hi guys,
I am fetching data from db table "mcha". now in the follwing code i get it in "HSDAT1_DATE."
now when i read out_tab with key "HSDAT1". it wont come in out_tab-value.plz tell me what is wrong whether some key condition in out_tab or any thing else.
and what should i write in changing && in script.
thanks in advance
FORM DATE_MGF TABLES IN_TAB STRUCTURE ITCSY
OUT_TAB STRUCTURE ITCSY.
tables :MCHA ,QALS.
DATA : WERKS1 LIKE QALS-WERK.
DATA : HSDAT1 LIKE MCHA-HSDAT.
DATA : DATE(2),
MONTH(2),
YEAR(4).
DATA : HSDAT1_DATE(10).
READ TABLE IN_TAB WITH KEY 'QALS-WERK'.
LOOP AT IN_TAB.
IF SY-TABIX EQ 1.
WERKS1 = IN_TAB-VALUE.
IF WERKS1 NE SPACE.
EXIT.
ENDIF.
ENDIF.
ENDLOOP.
SELECT SINGLE HSDAT INTO HSDAT1
FROM MCHA
WHERE WERKS = WERKS1.
DATE = HSDAT1+6(2).
MONTH = HSDAT1+4(2).
YEAR = HSDAT1+0(4).
CONCATENATE DATE '.' MONTH '.' YEAR INTO HSDAT1_DATE.
READ TABLE OUT_TAB WITH KEY 'HSDAT1' .
IF SY-SUBRC = 0.
OUT_TAB-VALUE = HSDAT1.
MODIFY OUT_TAB INDEX SY-TABIX.
ENDIF.Hi,
Let me understanf clearly what you want.
initally mine out_tab is blank
According to you, your table out_tab is blank. And you need to add out_tab-value = HSDAT1_date.
READ TABLE OUT_TAB WITH KEY 'HSDAT1' .
IF SY-SUBRC = 0.
OUT_TAB-VALUE = HSDAT1.
MODIFY OUT_TAB INDEX SY-TABIX.
ENDIF.
So, if your table is blank, then read statement will fail.
Please let me know if your table out_tab in blank when you are reading the table and if this table contains any field called HSDAT.
Basically i would like to know your internal table out_tab declaration.
Thanks,

Fetch data from different tables print them is assigned places
Hi Friends,
I have designed one SMART-Form (Receipt).
I need to fetch data from different tables and the data must be print in assigned places. Please help me how to achieve this requirement. Thanks for your help.
Best regards,
Manju.
Edited by: Alvaro Tejada Galindo on Feb 12, 2008 10:20 AMU're right.
When it creates a smartform it needs to decide when the main data have to be extracted:
- or in driver program
- or in smartforms
The difference can be in the performance, because the program can select the data only once, the smartforms needs to extract them everytime it's called.
I prefer to use a complex structure for the smartform interface as so all data I need are in only one structure, the problem is the complex structure is harder to be managed.
