Data access from weblogic

Hi,trying to figure out the most optimum of data access from weblogic. We initially used to do a preparestatement and then execute inside the dopost method of the servlets, but this causes the statement to be parsed everytime. To avoid this we decided to prepare the statements once in the init method of the servlets and do only an execute inside the dopost, but this causes the data in the resutl set objects to be mixed up if two or more users simultaneously accessed the same servlet(resutlsets are not thread safe??). To resolve this problem we did the executes inside a synchronized block but this is not very good for performance.So what is the best way?RgdsHarish

Make sure you declare your resultset locally.

Data fetch from table without Refresh and without using tab key.

hi Friends,
I have a problem i want to extract data from table without Refresh into text field without using Tab key. when i'll enter any value in a text field then corressponding value should come in to corressponding textfield without using Tab Key.
eg. when i enter emp_id 101 in a text field then the first_name and last_name ,adress should come in to corressponding text fields without refresh and without using Tab key.
How Can I do this.
Thanks
Manoj

Hi Manoj,
I assume that this is similar to: Data fetch without Refresh rather than Re: Value of one textfield should come into another textfield Without Using TAB ?
If so, the only change you need to make on the first one is to use "onkeyup" instead of "onchange" in the item's "HTML Form Element Attributes" setting.
Note, however, that the user must move away from the item at some point (for example, to click a button), so the onchange will be triggered anyway.

Data fetch from table

i have to select data from a database table into internal table but i want that it shud be selected as it is means i have a char 30 field which may have CAPS and small values in table but in the internal table it comes as all CAPS but it shud come as it is e.g "Data" shud come as "Data" in internal table but it comes as "DATA".

Just check the Domain of the concerned field. There will be a characteristic check box called "lower case" in the Definition tab of your domain. See if that is Flagged. If that is flagged, then the stored record will be case sensitive. In best practice, you should not have that flagged, So that the records will not be case sensitive and you will not have to face a similar situation.
Hope this helps.

Data relocation from table SOFFCONT1

Hi experts,
I have to relocate data from table SOFFCONT1 to an external repository with help of report RSIRPIRL...I went through all related Sap notes and it seems pretty straightforward.
When I run the report RSIRPIRL I see all the fields I have to fill up (I have already created an content repository as well as a catalogue) but my question is how to select some data manually for testing purpose? Is it any way how to see from table SOFFCONT1 just 1 file for example?? I couldn't see that field in the report RSIRPIRL.
Regards,
Blaiso

Applied OSS note 1536325 which will add an extra field to select by date and narrow the number of documents to test

Data retrivel from table ausp table

Helllo Experts,
I want to retrive data from table ausp based on the data retrived from the VBAK table.
I have selected data from VBAK and VBAP tabble using code :
SELECT VKORG VTWEG VBAKSPART VKGRP VKBUR KUNNR KNUMV VBAKVBELN VBAPMATNR VBAPARKTX INTO CORRESPONDING FIELDS OF TABLE GT_DATA
FROM VBAK INNER JOIN VBAP ON VBAKVBELN = VBAPVBELN
WHERE VKORG        IN SVKORG
AND VTWEG        IN SVTWEG
AND VBAK~SPART   IN SSPART
AND VKGRP        IN SVKGRP
AND VKBUR        IN SVKBUR
AND KUNNR        IN SKUNNR
AND MATNR        IN SMATNR.
SELECT MATNR BREIT ZEINR BRGEW INTO CORRESPONDING FIELDS OF TABLE GT_EANCODE FROM MARA
FOR ALL ENTRIES IN LT_DATA WHERE MATNR = GT_DATA-MATNR.
SORT GT_EANCODE BY MATNR.
ENDIF.
SELECT MATNR MVGR1 MVGR2 MVGR3 INTO CORRESPONDING FIELDS OF TABLE GT_MVGR FROM MVKE
FOR ALL ENTRIES IN LT_DATA WHERE MATNR = LT_DATA-MATNR.
SORT GT_MVGR BY MATNR.
ENDIF.
SELECT KNUMV KPOSN KSCHL KWERT INTO CORRESPONDING FIELDS OF TABLE GT_KONV FROM KONV
FOR ALL ENTRIES IN LT_DATA WHERE KNUMV = LT_DATA-KNUMV AND KSCHL IN ('ZG02').
SORT GT_KONV BY KNUMV.
So based on the material field in the table GT_DATA i have to select data from table ausp. The ausp table also having the field
material ( but the name of the material field in the ausp table is OBJEK) . Material field in t the VBAP table have data type character and field length 18 and OBJEC field in the ausp table have data type character and lenght 50.
So if i give select statement for ausp table
SELECT OBJEK ATINN ATWRT INTO CORRESPONDING FIELDS OF TABLE GT_AUSP FROM AUSP
FOR ALL ENTRIES IN GT_DATA WHERE OBJEK = LT_DATA-MATNR AND
          .                        MFID = '01' AND
                                   KLART = '001' AND
                                   ATINN = V_ATINN.
it is giving error : when you use addition for all entries in internal table the object and GT_DATA-MATNR must have same data type and same length.
So if i change the length of the matnr field it will effect for other select statement.
please let me know hw to over come errors.
Thakns in advace.
Best Regards,
Zubera

Hi shridarudupi ,
when you are declaring structure for GT_DATA,define matnr field of type ausp-objek , so when you will select data from AUSP using for all entries of GT_DATA , there will not be any type mismatch.
For Ex.
TYPES : BEGIN OF t_mara ,
         matnr TYPE ausp-objek,
         ersda TYPE mara-ersda,
        END OF t_mara,
         BEGIN OF t_ausp ,
         objek TYPE ausp-objek,
         atinn TYPE ausp-atinn,
        END OF t_ausp.
DATA : i_mara     TYPE STANDARD TABLE OF t_mara,
             i_ausp     TYPE STANDARD TABLE OF t_ausp,
            wa_mara LIKE LINE OF i_mara,
            wa_ausp LIKE LINE OF i_ausp.
SELECT matnr
             ersda
             FROM mara INTO TABLE i_mara
             WHERE matnr = '4510'.
IF sy-subrc = 0 .
SELECT objek
                atinn
                FROM ausp
                INTO TABLE i_ausp
                FOR ALL ENTRIES IN i_mara
                WHERE objek = i_mara-matnr.
IF sy-subrc = 0 .
    WRITE : 'successful'.
ENDIF.
ENDIF.
Hope this helps.

Fast data retreival from Table BSAD

Dear Friends,
I want to retrive data from table BSAD and right now it have more than 1,300,000 records.
for "where condition" i have Customer number, Document number, Document type fixed RV and only
debit side S.
What should i do for fast retreival or any function module . right now data fatching is too slow with simple select.
regards
Malik

Hi Malik,
Pass all the key fields present in the database table, and in the current selection you are using only 2 key fields. The remaining key fields in this table i.e, BSAD are:
BUKRS-----     BUKRS---     CHAR     4     0--
     Company Code
KUNNR-----     KUNNR---     CHAR     10     0--
     Customer Number 1
UMSKS------     UMSKS-----CHAR     1     0--
     Special G/L Transaction Type
UMSKZ------     UMSKZ-----CHAR     1     0--
     Special G/L Indicator
AUGDT-----AUGDT---DATS8     0--
     Clearing Date
AUGBL------     AUGBL------     CHAR--     10     0--
     Document Number of the Clearing Document
ZUONR-----DZUONR-     CHAR     180--
     Assignment number
GJAHR-----     GJAHR---     NUMC     4     0--
     Fiscal Year
BELNR-----     BELNR_D--     CHAR--10     0--
     Accounting Document Number
BUZEI--     BUZEI     NUMC     3     0--
     Number of Line Item Within Accounting Document
Therefore pass as many key fields as possible to improve the performance of the select query.

Md Ziauddin.

Data access from Application Server - Seeking Opinion

I am working on a fairly large scale ERP application that is written in Java both on the front end, and middle tier ( using a JBoss application server ).
All of the database access happens in my app server, and when I wanted to get peoples opinions on the best way to extract and pass data to and from the database from the app server, and of course to and from the client.
I am using JDBC to make database calls and extra data from the database. This is of course pretty trivial. And I first started writing POJO that represent tables in my database. I then wrote a faily length method that uses reflection to call the setting methods and pass in the objects returned from the database result set. This of course becomes tricky when you start to join multiple tables together. And often you only need a small subset of columns in a table and don't require an object with all the columns from the table ( some set, and some as null objects ).
So then I decided I was use a combination of ArrayList objects and HashMap's to store the data. If a result set returned multiple rows, it would return an ArrayList of HashMap objects. Each hash map would contain the data for that row, and the hash map keys are the column names.
This seems to work pretty well and resolves the problem of joining multiple tables together and keeping track of which columns get stored in which objects.
Does anyone have a different solution or idea as to how to handle this? And thoughts or ideas would be greatly appreciated.

If you had a table that had 40 columns in it and say 1000 rows. And you needed to run a query that returned all 1000 rows, but you only needed two out of the
40 columns. Would it be better to extract those two columns into the HashMap / ArrayList collection I mentioned in my original post? Or would using something like Hibernate and a class that mapped all of the columns in the table be okay?Why not just map the columns you needed in Hibernate? Who said you had to map all 40 and have them be null?
My concern is on efficiency,
and I was wondering if building 1000 objects that each have 40 members that only 2 are populated is the most efficient way of extracting the data.Doesn't sound very efficient.
I will admit, my knowledge of Hibernate is limited at best so I may be missing a component of Hibernate that would allow you to only extract the columns you required, but you are still working with an object that has 38 null value objects for the columns you didn't require.I don't believe you're required to map every column in a table.

Data fetch from table GLPCA taking long .

Hi Friends,
I am fetching five fields from GLPCA table and i have RACCT and RPRCTR ( account Number and profit Centre res ) in the where condition. neither of these field is the primary key of the table GLPCA. I have around 161096,482 entries in the GLPCA. It takes around 20 min to fetch the data. can you guys think of some method so that it works faster.

Hi Vidya,
The time utilization is due to the way data base is been accessed. Just think that you are selecting same data in SE16 with 200 hits. See how that behaves. If you find its Ok(i.e. around 1/2 mins) go for open cursor logic. Check this syntax and change the code accordigly and try:
OPEN CURSOR w_cur1 FOR
       SELECT ktabg vkorg ktaar ktaer kunnr
               vtweg spart
               FROM vbka
               WHERE ktabg IN so_ktabg AND
                     vkorg IN so_vkorg AND
                     kunnr IN so_kunnr AND
                     ktaar IN so_ktaar AND
                     ktaer IN so_ktaer.
    DO.
      FETCH NEXT CURSOR w_cur1 INTO CORRESPONDING
            FIELDS OF TABLE it_vbka2 PACKAGE SIZE 200.
      IF sy-subrc NE 0.
        CLOSE CURSOR w_cur1.
        EXIT.
      ENDIF.
   ENDDO.
It behaves just like Select ... Endselect. The most important thing here is the Pakage size which you have to decide based on the SE16 results. Also please mind that if the Package size is less, number of times it hits the DB is high, reducing the efficiency thereby.

Hi Amit,
Check if you are doing the following in your program
FIELD-SYMBOLS <T_TAB> TYPE STANDARD TABLE.
DATA: g_tabref type ref to data.   "Reference to your table structure
CREATE DATA g_tabref type standard table of (pa_tab).
ASSIGN g_tabref->* to <T_TAB>.
SELECT * FROM (PA_TAB) INTO TABLE <T_TAB>.
Hope this solves your problem.
Let me know if you require any further info.

Data selection from Table

Hi ,
My requirement is to have Commercial Documents which are not Accounted. So that I've used the following logic.
SELECT a~vbeln
                 a~vbtyp
                 a~fkdat
                 a~bukrs
         a~kunrg
         SUM( b~netwr )
       FROM vbrk AS a INNER JOIN vbrp AS b
       ON avbeln EQ bvbeln
       INTO ls_bill WHERE a~vbtyp EQ 'M'          AND
                          a~fkdat IN s_fkdat      AND
                          a~bukrs IN s_bukrs      AND
                          a~kunrg IN s_kunrg
                    GROUP BY a~vbeln
                             a~vbtyp
                             a~fkdat
                             a~bukrs
                             a~kunrg.
    l_awkey = ls_bill-vbeln.
    SELECT awkey FROM bkpf INTO l_awkey
                 WHERE awtyp EQ 'VBRK' AND
                       awkey EQ l_awkey AND
                       bukrs EQ ls_bill-bukrs.
    ENDSELECT.
    IF sy-subrc NE 0.
      APPEND ls_bill TO lt_bill.
    ENDIF.
    CLEAR : ls_bill, l_awkey.
ENDSELECT.
Is that the above logic for getting data is correct. or First taking all the entries from VBRK and VBRP table then selecting entries from BKPF and then if any entry of VBRK is not in BKPF then taking that.
