Collapsing two tables into one table or one queue

When you have data that exists in 2 tables A and B and B is essentially a child of A if you want to process these records such that you see all A's before their assoociated B how can you use either Streams or AQ to collapse these two tables into one? The data exists at it's source in database tables it will be replicated to another location and at that location I want to keep the data as it exists at the source but also process it in the ordered fashion I described above. My thinking is to publish the data to one queue but the challenge is to ensure that all A's are put on the queue before their B is. I don't just want a priority queue whereby all A's are processed before B's because if that happens B's will never be processed. but I simply want to avoid reading a B off the queue before I've read it's A.

No version number and no clarity of what you are trying to accomplish.
Without knowing that the problem is a nail ... I'd hardly be recommending using a hammer.

ABPA code to compress table into a table of fixed-length strings

Hi all,
I need to compress a large, sparse table into a table of fixed-length strings in my ABAP code, and then uncompress it. Is there a standard format or facility to do this? I seem to remember a function that does this, but any other hints would be appreciated.
Thank you in advance,
Sunny

For example, given a table like:
Column0    Column1    Column2
abc            C               !@#&@
                 P
def                              $*(
Compress it into a table consisting of one column of fixed-length strings, like:
Column0
0abc1C2
!@#&@01
P20def1
2$*(
..and then uncompress it back out to the original table.

Break table into multiple tables

I have a table with 700000 records and I need this data for calculating a value in excel using one of the third-party add-ins and then import all the data back into Oracle table. Since excel can only hold about 65000 records, I will have to break the oracle table into about 11 excel files each holding about 65000 records and then run my function and then import the calculated data back into Oracle. My question is how do I split the oracle table into 11 tables with each having 65000 records. There is no unique field in the table.
Format of table is like this;
num1 num2 cdat
12 43
12 34
45 65
32 45
I will need to use excel and calculate cdat column and then import it back to excel with cdat column calculated.
num1 num2 cdat
12 43 232
12 34 543
45 65 343
32 45 244
Any tips to guide me would be helpful.

No, I cannot do that because I have a third-party add-in that is installed in excel and it accesses its own proprietary database to peform some calculation and then gives the calculated number in excel. I cannot access this thirdparty database in oracle and I do not know the algorithm it uses to give me the desired number. The only option I have for now, is to get the data from oracle into excel, do my calculations and then import it back into oracle.

How can i put below table into internalt table

how can i put below table into internalt table and want to add both internal table into 3rd internal table.

ENDSELECT.
ENDSELECT.
please help
thanks in adavaced.

hi laxman,
use for all entries and get the required data.
SELECT * FROM J_1IEXCHDR into table itab1 WHERE STATUS = 'P'.
if not itab1[] is initial.
SELECT * FROM J_1IEXCDTL into table itab2 for all entries in itab1 WHERE TRNTYP = itab1-TRNTYP
AND DOCYR = itab1-DOCYR
AND DOCNO = itab1-DOCNO.
endif.
so itab2 will have the common records...This will solve ur problem..
also u can do other method declare an final internal table with the common fields of the two internal table.
then after getting data in itab1 and itab2.
loop at itab1.
move-corresponding itab1 to itab3.
read table itab2 with key <give the fields> = ......
if sy-subrc eq 0.
move-corresponding itab2 to itab3.
endif.
append itab3.
endloop.

Hi
You can use join for KNA1 and KNB1 which will much faster
then use for all entries of this itab to get the BSEG to improve the performance
here you need to do some trial and error method by joining removing the tables and also for all entries

INSERT of two records into different tables (pk value from first to second)

Hi there!
Have probably stupid question
Need to insert one record into table with primary key and then insert into other table record with value of primary key field from first record
How can I do it?
Thanks a lot!!!

You have several possibilities. Most easiest one is listed first :)
SQL> create table a (a number);
Table created.
SQL> alter table a add constraint a_pk primary key (a);
Table altered.
SQL> create table b (a number);
Table created.
SQL> alter table b add constraint b_a_fk foreign key (a) references a(a);
Table altered.
SQL> insert into a values (0);
1 row created.
SQL> insert into b values (0);
1 row created.Though that may not help always, so the next possibility maybe just using sequence with nextval and currval (currval can be used only in the same session and only after you have issued at least one nextval)
SQL> create sequence a_seq;
Sequence created.
SQL> insert into a values (a_seq.nextval);
1 row created.
SQL> insert into b values (a_seq.currval);
1 row created.And you can use also famous returning clause. It is a bit easier to show that in the pl/sql block than pure SQL.
SQL> declare
2   v number;
3 begin
4   insert into a values (a_seq.nextval) returning a into v;
5   insert into b values (v);
6 end;
7 /
PL/SQL procedure successfully completed.And at last contents of the tables :)
SQL> select * from b;
         A
         0
         1
         2
SQL> select * from a;
         A

Best way to JOIN 3 tables into internal table ?

Hi friends,
i have the following issue:
i need to join information of 3 different tables ( BUT000, BUT020 and ADRC ) concerning Business Partners and i need them into one internal table.
how would this be achieved with best performance ?
regards,
CL

Hi clemens,
As per my understanding, u can further improve this SQL By:
1. first select only BU000 and BU020 with inner join and then select material details in different different itabs. and process This will surely reduce load on DB and may increase load on ABAP which u can improve by using BINARY SERARCH!.
(Important: if u are using two table in join and giviing only PARTNER which is primary key field in both tables in WHERE clasuse ... this should be the only criteria in where clasue then i Dont think it will affect performance .... how many record may be there, this query will be BEST performer... I hope it will fetch 750000 records whithin few seconds)
2. Generally, U try to give more and more conditions in where clause on PRIMARY KEY fiedls only and not on not KEY fields...
3. In worst case, fetch data from three differnt tables into three different itabs and then process, this is best and last way to reduce load on DB and will increase load on ABAP which can be manages as above..
Still u want more info .. send codes to me.. We will try to make it more and more fast....

Breaking down SQL table into Multiple tables on the web using struts

I have a SQL table with business names and products. I am trying to display tables on a webpage for each individual business and their products. So one table is for each business and each business table lists all the products for that business. I'm not really sure how to do this.

Transform generated proxy tables into 'z' tables

Hello to everyone,
My doubt is really persistent and it's an important one...
Imagine we have an wsdl and we create a enterprise service proxy client. The R3 will generate 'Z' tables for the structure which the webservice needs for the request and the response.
How can I transform those generated proxy tables into normal 'Z' tables from the R3 Dictionary database?
Is it possible? Or do I have to create similar tables to the proxy tables?
The problem is that the response structure is really huge, and the work needed to create all the tables necessary to acomodate and all the mapping between the generated proxy tables and the ones that I'll have to create is HUGE!!!... Can I transform in any way those proxy tables?
Any help will be appreciated....

Hello Gonçalo
The generated proxy tables are indeed structures (and table types). In your case you have plenty of these structures that have to be "converted" into normal Z-tables.
One approach would be to use an
eCATT for this task. The steps could be as following:(1) Create a new z-table
(2) Include the corresponding proxy structure
(2.a) Transfer fields from include and remove .INCLUDE reference
(3) Remove obsolete fields
(4) Add additional fields
(5) Generate the z-table

Pass Structured table into dynamic table parameter in public method

Ladies and Gentlemen,
I have a requiremet to pass (1 at a time) any number of tables into a reuseable method in a custom class. The Method code is as follows:
method CREATE_OUTBOUND_FILE.
* Importing VALUE( IV_PATHNAME ) TYPE PATHEXTERN File Destination
* Importing VALUE( IT_FILE_RECORD ) TYPE REF TO DATA Table with Output
* Importing VALUE( IV_RECORD_STRUCTURE ) TYPE STRING OPTIONAL Record Structure
* Importing VALUE( IV_DELIMITER )     TYPE STRING     File Delimiter
* Exporting VALUE( EV_RECORD_CNT ) TYPE STRING Record Count
Data:
        ls_line_cnt(6) type n,
        lt_data_struc type zty_ddic_struc_T,
        ls_string      type string.
field-SYMBOLS: <fs_string> type any.
* Open Dataset for outputting file details
Open dataset iv_pathname for output in text mode encoding default.
Assign ls_string to <fs_string> CASTING TYPE (iv_record_structure).
loop at it_file_record into <fs_string>.
    transfer <fs_string> to iv_pathname.
    Add 1 to ls_line_cnt.
    clear <fs_string>.
endloop.
ev_record_cnt = ls_line_cnt.
where IV_PATHNAME = output destination & filename
            IT_FILE_REC     = data table
            IV_RECORD_STRUCTURE = is ddic structure definition for the data table
            IV_DELIMITER = file delimiter, in this case, let's say it's C (for CSV)
     and EV_RECORD_CNT is a count of numbe of records processed.
Lets say, for example, I wish to load data from table SFLIGHT into the method when program A is executed. Then another time I wish to excute Program B which is passing in data of table SFLCONN2. I hope that by using the "type ref to data" defintion, I can pass the table contents through. Is this true?
Secondly, I'm getting a syntax error saying that "IT_FILE_RECORD" is not defined as a table (and therefore can't be looped at), and therefore can't be read. How can I access the data in this table in preparation for output.
Any assistance or thoughts would be greatly appreciated.
Regards,
Steve

Hi Stephen ,
Graham already gve part of the solution.
If you declare
Importing VALUE( IT_FILE_RECORD ) TYPE REF TO DATA
it does not make sense to declare to pass by VALUE because you will not change this refernce in the method. Calling this method, you must pass a refefernce.
data:
lr_ref type ref to data.
get reference of <your itab here> into lr_ref.
CREATE_OUTBOUND_FILE( ...IT_FILE_RECORD = lr_ref ... )
In the method, it goes as graham explained.
Anyway, I would declare the table parameter as
Importing IT_FILE_RECORD TYPE TABLE
The your code could work, but you will have troube with any non-character fields in the tables.
Regards,
Clemens

Split Excel tables into individual tables in Numbers

Is there a way, having opened a file with multiple tables from excel, to make them into separate tables in Numbers. The tables have links between them and if I copy paste into a new sheet I lose the link. I no longer have access to Excel to put them all on separate Tabs. Thanks

Select a range of cells, press shift-command-X (mark for move), go to a cell in the new table and press shift-command-V (move).

How to pass the data of the dynamic table into internal table

Hi all,
I had designed an Dynamic table in my Online Interactive form.
I am able to pass only the First row data into the internal table which i had created
Now how can i pass data of all the rows into the internal table.
Needed some coding help
Thanks
Ajay

Hello Ajay,
If you have dynamic table in adobe and you want to capture all the added rows then you need to add corresponding element in the node bound to that table ui.
when u add a row using java script in adobe form there is no corresponding element created in the backend that is ur wd node bound to the table ui. and so u only get 1 row of data back.
try this,
create a button in your view holding adobe form say "add rows" and on click of this button write the code to add one more element to the node bound to ur table ui of adobe form. when server side rendering occurs it will recreate the table in adobe with added row in the node and you will be able to get the data entered by user.
Thanks,
Abhishek
