Single row editing for multiple tables in a single page

Hi!
I have split a table with many many columns into more tables with a lower number of columns. There is an ID column (sequence generated) that is Primary Key common for all tables. Obviously, the relationship between these tables is 1 to 1, so its not about having to build master-detail pages.
What I need now is to edit all these tables in a single page: one single row from each table. The Automated Row Fetch & Automatic Row Processing (DML) processes used for the old table must be replaced by something else.
Is there a way to use in a single page more pairs of such processes for more tables?
I want to avoid manually writing processes with lot of PL/SQL code to handle row fetch & update.
Keep in mind that the page will have an ID item that can be used to identify unique rows in all my tables.
Thanks,
Sorin

I have split a table with many many columns into more tables with a lower number of columns
IMHO that is a very bad idea. There is nothing wrong with having many columns in a table. If you would like to split them to better "categorize" them, just create views on the table and expose different subsets of the columns.
I want to avoid manually writing processes with lot of PL/SQL code to handle row fetch & update.
That is unavoidable given how you have designed the underlying tables.
You could try creating a view that joins all the tables by the PK and creating a form based on that view. Then write a INSTEAD OF trigger on the view that "doles out" the DML on the view to each of the underlying tables.

Can we use single DB Adapter for multiple tables

Hi,
I have 3 tables. ONE is the Master table and other 2 tables having Primary and foreign key relationships with the Master Table.
Data is enter in the Tables 2 & 3 (based on Master Table Primary key)
I have to use a DB Adapter in BPEL Process which will be in Transaction (what type of Transaction is Best in such a Scenario).
- How do i implement it in BPEL.
- Can i use a Single DB Adapter for Multiple Tables ? (*Views* should not be created for tables 1, 2 & 3),
as we want to avoid using multiple DB Adapters, as in future Tables may increase or decrease...
- while in Transaction if Table 2 fails in Inserting / Updating, it should roll back on error and also if Table 3 fails in Inserting / Updating, it should roll back table 2 and Table 3.
- how access to concurrent users is maintained / managed in such a scenarios.
But everything should be done using Single DB Adapter without creating a separate view.
Is this Possible in BPEL..
If not, How do we design, Implementation such a BPEL Process in Transaction with a best in Performance (both BPEL Process & DB Resources)
thanks in advance
thanks & regards,
anvv sharma

Hi,
Thanks for your quick response.
I have few quires.
If we use PL/SQL, how do we implement transaction and Exception Handling appropriately based on the Error / Exception in BPEL.
If the Table 2 or Table 3 gives out Error / Exception, i have to handle it separately and intimate accordingly.
Suppose, if Table 2 got Error / Exception - Error Handling would be 'Roll back due to error in Table2'
Thanks & regads,

Single Update query for multiple tables

Hiii ....
I want to update Table A and Table B in a single update query can it be possible.
it is something like i have previously done with Mysql.
e.g ..
UPDATE A, B set a.A=1, b.B=X where (id.A= id.B) and id=101.
Is it possible or how can i do it, help me out.

sorry, i am posting the mysql example agin, it is something like this
e.g ..

TO MAKE SINGLE ROW EDITABLE IN WEBDYNPRO ABAP

HI
I WANT TO MAKE A SINGLE ROW EDITABLE IN MY TABLE CONTROL IS IT POSSIBLE?
IF YES THEN HOW?
I KNOW ABOUT READ ONLY FIELDS BUT I DO NOT KNOW HOW TO UTILIZE IT

Hi Rajan,
Which particular row of the table do you want to set as editable? That would be important for formulating the way in which you should code.
Suppose you are displaying the data of MARA using a table and want to make editable only rows in which the unit of measurement is equal to "CCM" then you can proceed as below.
Create a context node (say MARA) with desired fields as attributes. (Cardinality 0..n, Selection 0..1, Initialize lead selection) In addition create an attribute (say READONLY) of type WDY_BOOLEAN under the same node (MARA) which you are using for binding to the table.
First of all take all the cell editors of the table as type, "InputField" to make the entire table as editable. Then go to the each cell editor (TABLE_MATNR_EDITOR, TABLE_ERSDA_EDITOR,...) and bind the readOnly property of the cell to the attribute created earlier. (READONLY)
Below is the coding in WDDOINIT through which you set the desired functionality
METHOD wddoinit .
DATA: lv_node TYPE REF TO if_wd_context_node,
        lt_mara TYPE ig_componentcontroller=>elements_mara,
        wa_mara TYPE ig_componentcontroller=>element_mara.
SELECT matnr
         ersda
         ernam
         mtart
         matkl
         meins FROM mara INTO CORRESPONDING FIELDS OF TABLE lt_mara
                                 WHERE meins = 'GM' OR meins = 'CCM'.
SORT lt_mara BY meins.
lv_node = wd_context->get_child_node( name = wd_this->wdctx_mara ).
LOOP AT lt_mara INTO wa_mara.
    IF wa_mara-meins = 'GM'.
      wa_mara-readonly = 'X'.
    ELSE.
      wa_mara-readonly = ' '.
    ENDIF.
    MODIFY lt_mara FROM wa_mara TRANSPORTING readonly.
ENDLOOP.
lv_node->bind_table( new_items = lt_mara ).
ENDMETHOD.

Merging of multiple rows in an internal table as a single record

Hi All,
I have an internal table which has the following columns:
text, date, time, user.
it stores notes in the internal table.
The problem is...when I save a note with multiple lines and spaces it saves each line of the note as a row in the internal table.
Thus i get more no. of rows in the internal table compare to the no. of rows!
I need to store each notes as single row in the internal table.
Please advise how to approach this?
Helpful answers will be rewarded.
Thanks & Regards,
Anshumita.

You can create a deep internal table. You can declare one Column as an internal table and store the NOTES in that Internal table for each row.

You could use SQL*Loader to load the data into a staging table with a varray column, then use a SQL insert statement to distribute it to the destination table, as demonstrated below.

[ADF Help] How to create a view for multiple tables

Hi,
I am using Jdeveloper 11G and ADF framework, and trying to create a view to update multiple tables.
ex:
Table A has these fields: ID, Name
Table B has these fields: ID, Address
A.ID and B.ID are primary keys.
B.ID has FK relationship with A.ID
(basically, these tables have one-to-one relation)
I want to create a view object, which contains these fields: B.ID (or A.ID), A.Name, B.Address.
So I can execute C,R,U,D for both tables.
I create these tables in DB, and create entity objects for these tables.
So there are 2 entity objects and 1 association.
Then I create a view object based on B and add fields of A into the view:
If the association is not a "Composition Association",
when I run the model ("Oracle Business Component Browser") and try to insert new data, fields of A can't edit.
If the association is a "Composition Association", and click the insert button, I will get
"oracle.jbo.InvalidOwnerException: JBO-25030: Failed to find or invalidate owning entity"
If I create a view object based on A and add filed of B into the view:
When I run the model and try to insert new data, fields of B can't edit, no matter the association is or is not a composition association.
So... how can I create a view for multiple tables correctly?
Thanks for any advices!
Here are some pictures about my problem, if there is any unclear point, please let me know.
http://leonjava.blogspot.com/2009_10_01_archive.html
(A is Prod, B is CpuSocket)
Edited by: user8093176 on Oct 25, 2009 12:29 AM

Hi Branislav,
Thanks, but the result is same ....
In the step 2 of creating view object, I can select entity objects to be added in to the view.
If I select A first, and then select B (the "Source Usage" of B is A), then finishing the wizards.
When I try to create a new record in the view, I can't edit any properties of B (those files are disabled).
If I select B first, and then select A in crating view object, the result is similar ...
Thanks for any further suggestion.

Single Transfer Order for Multiple Handling Units

I have been researchig the ability to create a single transfer order for multiple handling units. My assumptions are if it can be done that:
1) A transfer order can have a single source, so if the source document for the handling unit (delivery) is different, that means different transfer order
2) A TO can have multiple materials (line items) with different destination bins and quantities per bin
I looked at the configuration for TO Split, but it's not clear that this will handle my requirement.
I also saw this http://aq33.com/material-management/Articles-005798.html and it also says that my requirement can't be meant. I'm just checking before I tell my customer this cannot be done.

Yes you are right, if Source document is different, you need to go with different TO.
But you can choose the Handling unit split, while creating a TO itself. i.e., You can quantify the goods for each handling unit.

Single Supplimentary Invoice for Multiple Invoices

Hi
We are having Standardmanufacturing sales Process
Ex: We did the sales of 1000 quantity of goods over the period of time for Price 100 Rs/ and we had created invoices also in the system .After 3 months with the customer on mutual undersating we have decided to hike the price 110 Rs on excisting sales, Now i want to create Single Supplimentary invoice for multiple Invoices for the hiked amount 10,000 Rs( 1000 *10=10,000) along with Excise duties.
Please help me out to map this senario in sap
Thanks

Edited by: mujubur shaik on Nov 9, 2009 8:06 AM

Dear Mujubur,
It is generic feature of a business that price is changed for various reasons. So excise accounting is adjusted corresponding it.
What you do, please create a debit memo request which is a sale order type document by VA01 with reference of all commercial inovices against which you want to create the single supplementory invoice. Then create a debit memo which is a bimming document by VF01 with reference of that debit memo reuest and do the release to accounting.
Then part A/C will be debited and all other corresponding accounts with Excise provision A/C will be creadited. Now create a billing type as proforma invoice (Bill category U) in configuration and mainatin the copy control from debit memo document type.
It is better to do the configuration first. Then create the proforma invoice with reference of that debit memo. It will be like a image document of the debit memo. Then create excise invoice by J1IIN with refernce of that proforma invoice with different number series if you want tom maintain. Then excise account will take place - Ex provision Dr , ED payable Cr. That Excise document is your desired supplementory excise invoice. It will also come in the scope of excise utilisation in J2IUN. The proforma invoice is to be created other wise excise document with transaction type DLFC will not vecreated as it creates only from proforma inovice , not from any other type of billing document.
Don't go for Excise JV. Apparemntly it is seemed that will be easier but your accounting will be wrong and there will be no track of data which will lead a problem for long run.
Please do it. If more help required then inform. I have implemedted the same process.
Hope this will serve your purpose.

WHERE matnr = i_marc-matnr.
LOOP AT i_mard.

How to get row count(*) for each table that matches a pattern

I have the following query that returns all tables that match a pattern (tablename_ and then 4 digits). I also want to return the row counts for these tables.
Currently a single column is returned: tablename. I want to add the column RowCount.
DECLARE @SQLCommand nvarchar(4000)
DECLARE @TableName varchar(128)
SET @TableName = 'ods_TTstat_master' --<<<<<< change this to a table name
SET @SQLCommand = 'SELECT [name] as zhistTables FROM dbo.sysobjects WHERE name like ''%' + @TableName + '%'' and objectproperty(id,N''IsUserTable'')=1 ORDER BY name DESC'
EXEC sp_executesql @SQLCommand

The like operator requires a string operand.
http://msdn.microsoft.com/en-us/library/ms179859.aspx
Example:
DECLARE @Like varchar(50) = '%frame%';
SELECT * FROM Production.Product WHERE Name like @Like;
-- (79 row(s) affected)
For variable use, apply dynamic SQL:

Rows count all tables:

User Datastore for multiple tables and columns!

Hi,
I hop so much, someone can help me.
I've made a user datastore to index multiple columns of multiple tables.
Now, the Documentation of Oracle explains the idexing of one table.
I have multiple tables, which have all, the columns descr and tagnr. I want to make a query sth like this:
select table1.column, table2.columnd... where contains(indexed field,'gas within descr',1)>0
is it possible to index 4 seperate tables, without having a collective key? I dont want to make a Concatenated Datastore.
I have wrote this code.
But it doesn't work. It's been compiled fine. But I don't get any result with my queries.
create or replace
procedure My_Proc_Wide
Must be in ctxsys schema.
In a full-scale example, this would be a wrapper
for a proc in the user schema.
rid in rowid,
tlob in out NOCOPY clob /* NOCOPY instructs Oracle to pass
this argument as fast as possible */
is
v_descr varchar2(80);
v_tagnr varchar2(30);
v_descr_name constant varchar2(20) := 'descr';
v_descr_start_tag constant varchar2(20) := '<' || v_descr_name || '>';
v_descr_end_tag constant varchar2(20) := '</' || v_descr_name || '>';
v_tagnr_name constant varchar2(20) := 'tagnr';
v_tagnr_start_tag constant varchar2(20) := '<' || v_tagnr_name || '>';

begin
/* verify the env which called this */
if Dbms_Lob.Istemporary ( tlob ) <> 1
then
raise_application_error ( -20000,
'"IN OUT" tlob isn''t temporary' );
end if;
/* the real logic */
/* first tabel to be indexed */
select t1.tagnr, t1.descr
into v_tagnr, v_descr
from tweb.pdp_positions t1
where t1.rowid = rid;
v_buffer := v_tagnr_start_tag ||

/* second table to be indexed */
select t2.tagnr, t2.descr
into v_tagnr, v_descr

where t2.rowid = rid;
     v_buffer := v_tagnr_start_tag ||

     v_descr ||
     v_descr_end_tag;
v_length := length ( v_buffer );
Dbms_Lob.WriteAppend(tlob, length(v_buffer) + 1, v_buffer || ' ');
/*third table to be indexed */
select t3.tagnr, t3.descr

where t3.rowid = rid;
     v_buffer := v_tagnr_start_tag ||

v_tagnr_end_tag ||
v_descr_start_tag ||
     v_descr ||
     v_descr_end_tag;
v_length := length ( v_buffer );
Dbms_Lob.WriteAppend(tlob, length(v_buffer) + 1, v_buffer || ' ');
/* fourth table to be indexed */
select t4.tagnr, t4.descr
into v_tagnr, v_descr
from tweb.pdp_Projcode t4
where t4.rowid = rid;
     v_buffer := v_tagnr_start_tag ||

     v_descr_end_tag;
v_length := length ( v_buffer );
Dbms_Lob.WriteAppend(tlob, length(v_buffer) + 1, v_buffer || ' ');
end My_Proc_Wide;
what have I to do, to make this work?
Any Help would be appriciated!!
Kind Regards,
Arsineh

Arsineh,
I realise that it has been quite some time since you posted this question but I thought I'd reply just in case you never did manage to get your user datastore working.
The reason your procedure will not work is simple. A user datastore procedure accepts a rowid input parameter. The rowid is the ID of the row that Oracle Text is currently trying to index. In the example you have given, you are attempting to use the supplied rowid as the primary key for multiple tables, this will simply never work as the rowid's across multiple tables will never correspond.
The best way to achieve your goal is to create the index on a master table which contains the common primary keys for each of your four tables e.g.
MASTER_TABLE
COL:COMMON_KEY (NUMBER(n))
COL:USER_INDEX_COLUMN (VARCHAR2(1))
If you create the user datastore index on the MASTER_TABLE.USER_UNDEX_COLUMN column your stored proc simply needs to read the correct row from the MASTER_TABLE (SELECT t.common_key into v_CommonKey FROM master_table t WHERE t.rowid = rid) and issue subsequent queries to extract the relavant data from the t1..t4 tables using the common key e.g.
SELECT t1.tagnr, t1.descr into v_tagnr, v_descr FROM t1 WHERE t1.[PRIMARY_KEY_FIELD] = v_CommonKey;
SELECT t2.tagnr, t2.descr into v_tagnr, v_descr FROM t2 WHERE t2.[PRIMARY_KEY_FIELD] = v_CommonKey;
and so on...
Hope this helps

Get row count for different tables to the same line

How can I get the row count for different tables in one line:
SELECT count(A), count(B), count(C) from table tb_a A , tb_b B, tb_c C;
Thanks!

>
Hi,
How can I get the row count for different tables in one line:
SELECT count(A), count(B), count(C) from table tb_a A , tb_b B, tb_c C;Something like this? One of the many uses for CTE's - Common Table Expressions - AKA
subquery refactoring. Worth getting to know - very handy!
with acount as
select count(*) as counta from dual -- put your table name here
bcount as
select count(*) as countb from dual -- put your table name here
ccount as
select count(*) as countc from dual -- put your table name here
select a.counta, b.countb, c.countc from acount a, bcount b, ccount c;HTH,
Paul...

Single result set across multiple tables

Hi - what's the best way to perform a single query that can pull
a single result set across multiple tables, ie., a master table
containing subject details and child table containing multiple
records with detail.
I know how to do this for two columns in the same table via
indexing, but how about across tables?
Cheers,
John

I am not sure if I understood your question, but you can use
Intermedia Text with USER_DATA_STORE to create an index with data
source from multiple tables.
(see technet.oracle.com -> products -> oracle text)
