Fetch data from one table and insert into two tables in desired format

I have similar to the following data in a table and it is not normalized. The groupID is being used to group two records of similar nature.
DECLARE @OldDoc TABLE (oldDocID INT, groupID INT, deptID INT)
INSERT INTO @OldDoc (oldDocID, groupID) VALUES (1, NULL, 111),(2,NULL,111),(3,1,111),(4,NULL,333),(5,1,222),(6,NULL,333),(7,2,222),(8,2,333),(9,NULL,111),(10,3,222),(11,NULL,333),(12,3,444)
I need to process the data from the above table (@OldDoc) and write into two new tables (@NewDoc and @NewDocGroup) as follows.
oldDocID should be stored as newDocID when inserting to @NewDoc table. Only records with groupID NULL and one record (first one) per group should be considered (For example, oldDocID 5 is not considered as 3 and 5 belong to the same groupID 1) for insertion.
DECLARE @NewDoc TABLE (newDocID INT)
INSERT INTO @NewDoc (newDocID) VALUES (1),(2),(3),(4),(6),(7),(9),(10),(11)
All records from @OldDoc should be considered for insertion into @NewDocGroup table. OldDocID is inserted as NewDocID and deptID is as-is. Instead of groupID, the ID of the first record in the
group should be considered as parentNewDocID (For example, 3 is considered as parentNewDocID for newDocID 5 as 3 and 5 belong to the same groupID in @OldDoc table) for the newDocID.
DECLARE @NewDocGroup (newDocID INT, parentNewDocID INT, deptID INT)
INSERT INTO @NewDocGroup (newDocID, parentNewDocID, deptID) VALUES (1,1,111),(2,2,111),(3,3,111),(4,4,333),(5,3,222),(6,6,333),(7,7,222),(8,7,333),(9,9,111),(10,10,222),(11,11,333),(12,10,444)
How do I accomplish the above using SQL ? Thanks for the help.

Rows are not records. Tables have to have a key by definition. You do not do math with identifiers, so they should not be numeric. Let's ignore that error for now. In short, you are posting garbage. If you had followed Forum Netiquette, would you have posted
this?
CREATE TABLE Old_Documents
(old_doc_id INTEGER NOT NULL PRIMARY KEY,
group_id INTEGER,
dept_nbr INTEGER NOT NULL
REFERENCES Departments (dept_nbr));
INSERT INTO Old_Documents(old_doc_id, group_id, dept_nbr)
VALUES (1, NULL, 111),
(2, NULL, 111),
(3, 1, 111),
(4, NULL, 333),

Just like punch cards and mag tape data processing! Being old and being new are a status, not another kind of entity. But that is how mag tapes work. And you even use the verb "fetch" from tape files. This design flaw is called attribute splitting.
Do you have a Male_Personnel and Female_Personnel table? NO! It is just Personnel!
>> old_doc_id should be stored as new_doc_id when inserting to New_Documents table. Only records [sic] with group_id NULL and one record [sic] (first [sic; no ordering in a table] one) per group should be considered (For example, old_doc_id 5 is not considered
as 3 and 5 belong to the same group_id =1) for insertion. <<
Think about your punch card mindset. Why did you physically materialize that redundant New_Documents table? Let me answer that: this is how you work with punch cards! In SQL we use a VIEW:
CREATE VIEW New_Documents (new_doc_id)
AS
SELECT old_doc_id
FROM Old_Documents;
>> All records [sic] from Old_Documents should be considered for insertion into New_Documents_Groups table. The old_doc_id is inserted as new_doc_id and dept_nbr is as-is. Instead of group_id, the ID [sic: which identifier??] of the first [sic: tables
have no ordering like a deck of punch cards] record [sic] in the group should be considered as parent_new_doc_id (For example, 3 is considered as parent_new_doc_id for new_doc_id 5 as 3 and 5 belong to the same group_id in Old_Documents table) for the new_doc_id.
<<
Why not use 5 as the parent? My guess is that you are trying to form equivalence classes. See:

Fetch data from two tables and insert into one table

I have similar to the following data in two tables (@Plant, @PlantDirector) and need to consolidate into one table (@PlantNew) as follows.
DECLARE @Plant TABLE (PlantID INT, PlantName VARCHAR(100))
INSERT INTO @Plant (PlantID, PlantName) VALUES (1, 'Name One'),(2, 'Name Two'),(3, 'Name Three'),(4, 'Name Four'),(5, 'Name Five'),(6, 'Name Six')
Director data for the Plants exist in the following table. Assistant value 1 means Assistant Director and 0 means Director.
Data exists only for subset of plants and a Plant may have one or both roles.
DECLARE @PlantDirector TABLE (PlantID INT, PlantDirectorID INT, Assistant bit)
INSERT INTO @PlantDirector (PlantID, PlantDirectorID, Assistant) VALUES (2, 111, 1),(2, 222, 0),(4, 333, 0),(6,444,1)
The above data needs to be inserted into one table (@PlantNew) as follows:
PlantID in @Plant table is IDENTITY value and needs to be inserted as-is into this table.
PlantDirExists will get a value of 1 if at least one record exists in @PlantDirector table for a PlantID. PlantAssistantDirID and PlantDirID should be set to the corresponding PlantDirID or NULL appropriately depending on the data.
DECLARE @PlantNew TABLE (PlantID INT, PlantName VARCHAR(100), PlantDirExists bit, PlantAssistantDirID INT, PlantDirID INT)
INSERT INTO @PlantNew (PlantID, PlantName, PlantDirExists, PlantAssistantDirID, PlantDirID)
VALUES (1, 'Name One', 0, NULL, NULL),(2, 'Name Two', 1, 111, 222),(3, 'Name Three', 0, NULL, NULL),(4, 'Name Four', 1, NULL, 333),(5, 'Name Five', 0, NULL, NULL),(6, 'Name Six',1, 444, NULL)
How do I achieve the above using SQL ? Thanks.

like this
INSERT @PlantNew (PlantID, PlantName, PlantDirExists, PlantAssistantDirID, PlantDirID)
SELECT p.PlantID,
p.PlantName,
CASE WHEN pd.PlantID IS NULL THEN 0 ELSE 1 END,
PlantAssistantDirID,

GROUP BY PlantID)pd
ON pd.PlantID = p.PlantID
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs

Read data from E$ table and insert into staging table

Hi all,
I am a new to ODI. I want your help in understanding how to read data from an "E$" table and insert into a staging table.
Scenario:
Two columns in a flat file, employee id and employee name, needs to be loaded into a datastore EMP+. A check constraint is added to allow data with employee names in upper case only to be loaded into the datastore. Check control is set to flow and static. Right click on the datastore, select control and then check. The rows that have violated the check constraint are kept in E$_EMP+ table.
Problem:
Issue is that I want to read the data from the E$_EMP+ table and transform the employee name into uppercase and move the corrected data from E$_EMP+ into EMP+. Please advise me on how to automatically handle "soft" exceptions in ODI.
Thank you

Hi Himanshu,
I have tried the approach you suggested already. That works. However, the scenario I described was very basic. Based on the error logged into the E$_EMP table, I will have to design the interface to apply more business logic before the data is actually merged into the target table.
Before the business logic is applied, I need to read each row from the E$EMP table first and I do not know how to read from E$EMP table.

How to get the data from one table and insert into another table

Hi,
We have requirement to build OA page with the data needs to be populated from one table and on save data into another table.
For the above requirement what the best way to implement in OAF.
I understand that if we attach VO object instance to region/page, we only can pull and put data in to only one table.
Thanks

You can achieve this in many different ways, one is
1. Create another VO based on the EO which is based on the dest table.
2. At save, copy the contents of the source VO into the dest VO (see copy routine in dev guide).
3. commiting the transaction will push the data into the dest table on which the dest VO is based.
I understand that if we attach VO object instance to region/page, we only can pull and put data in to only one table.
if by table you mean a DB table, then no, you can have a VO based on multiple EOs which will do DMLs accordingly.Thanks

Table Scan Insert Delete

I have 1 View(A_VW) and 1 Table (B_TBL)
I want to be eifficent in table scan . prefer only one scan
Samplw Table below.
if Amount > 500 and New reord added in A_VW. The table also adds this row.
If a record is Deleted in A_VW then we delete the record if its STATUS in B_TBL is N
If Experiy Date is the same as sysdate then change the status from Y to N. There are around say a million records.
I am trying out the pseudo code for this and if anyone can help that will be great.
default status and code is Y and can assume default epr date as 30 days from inserted date.
A_VW
USERNAME AMOUNT
ABC1......... 200
abc2.......... 700
B_TBL
USERNAME STATUS Expiry DATE
abc2........... N.........1/12/2004
sscs.......... N.........1/31/2006

Trigger a process(IDOC) when Data in Z-table updated

Hi All,
I am working on an interface and the outbound IDOC from R/3 to XI needs to be triggered when a particular field value in a Z*table changes.
So far I am able to trigger the IDOC from the calling Z*prog which updates this table, but I need some exit, PAI etc which will get triggered only when the data in table is updated.
Current Flow chart:
Z-prog starts--->Updates a Z-table--->if sy-subrc=0--->I create an IDOC from the Z-prog itself
What I need:
Z-table is updated--->check if particular filed value changed--->Trigger IDOC
Is it possible to do this.
Many thanks
Shirin

Hi Balu,
I am triggering my IDOCS from the Z*program itself.
The trigger point is when I have successfully updated the table (sy-subrc = 0).
Then I have used the code below to populate my IDOC. I have also maintained a distribution model, so that is the reason I pass only the idoc type in edidc segment and do not pass any port , receiver etc.
Hope you find the code useful.
Regards
Shirin

Refresh af:table when data in another table changes

Hi
I am using jdev 11.1.1.7.0 and using bean datacontols..
I have 2 tables in the same page..
1. Language table
2. Items table
Language table has CRUD operations like user can created new language. The items table is a dynamic table with one fixed column that is "item" and remaining are the language columns.
So, if user give 3 languages in first table then the second table will have "item" + 3 columns i.e 1 column for each language. .
Because these 2 tables are on the same page.. I need to refresh the items table to show new column when user creates new language in the language table.. what is the best way of doing this?
Thanks

Jdev 11.1.1.7 is not oficialy released yet, so I suppose you are Oracle employee, right ?
As I understand, you have you own internal forum, right ?
BTW, you probably have something like "Commit" button, or similar. So set partlalTrigger for the Items table to that Commit button...

How to read LONG RAW data from one table and insert into another table

Hello EVERYBODY
I have a table called sound with the following attributes. in the music attribute i have stored some messages in the different language like hindi, english etc. i want to concatinate all hindi messages and store in the another table with only one attribute of type LONG RAW.and this attribute is attached with the sound item.
when i click the play button of sound item the all the messages recorded in hindi will play one by one automatically. for that i'm doing the following.
i have written the following when button pressed trigger which will concatinate all the messages of any selected language from the sound table, and store in another table called temp.
and then sound will be played from the temp table.
declare
     tmp sound.music%type;
     temp1 sound.music%type;
     item_id ITEM;
cursor c1
is select music
from sound
where lang=:LIST10;

     open c1;
     loop
          fetch c1 into tmp; //THIS LINE GENERATES THE ERROR
          temp1:=temp1||tmp;
          exit when c1%notfound;
     end loop;
CLOSE C1;
insert into temp values(temp1);
item_id:=Find_Item('Music');
go_item('music');
play_sound(item_id);
end;
but when i'm clicking the button it generates the following error.

How to know when an object is deleted?

Hi,
In Java, instances of classes are eliminate by garbage collector and programmers have no chance to do it.

} // class TableClientsthis code works well...
But if I implement the javaBeans on more than one Dialogs (windows) and the user uses
this dialogs sequentially, then the JavaBean responds to the events always as the caller is the
first dialog that run...
If I delete all listener (on the dialog) when the dialog is close then I have not problems
still thank you

Procedure to insert data into table by selecting data from another table

Hi all,
I have to create a procedure where i have to select the data from one table and insert it into another table. Any help on this. And i have to update the 2nd table also when ever new records got inserted in the 1st table then.
Regards

Hi, you can try something like:
CREATE [OR REPLACE] PROCEDURE procedure_name
IS
BEGIN
INSERT INTO TABLE1
VALUES (SELECT * FROM TABLE2);
END;
For the other part you may create a trigger on the first table AFTER INSERT to insert the values in the second table too.

To know when data in a table is inserted,deleted.
