For this do we need to apply CDC?
I am not clear on how to delete rows under target, Can you please share the steps to be followed.If you are able to track the deletes in your source data then you dont need CDC. If however you cant - then it might be an option.
I'll give you an example from what im working on currently.
We have an ODS, some 400+ tables. Some are needed 'Real-Time' so we are using CDC. Some are OK to be batch loaded overnight.
CDC captures the Deletes no problem so the standard knowledge modules with a little tweaking for performance are doing the job fine, it handles deletes.
The overnight batch process however cannot track a delete as its phyiscally gone by the time we run the scenarios, so we load all the insert/updates using a last modified date before we pull all the PK's from the source and delete them using a NOT EXISTS looking back at the collection (staging) table. We had to write our own KM for that.
All im saying to the OP is that whilst you have Insert / Update flags to set on the target datastore to influence the API code, there is nothing stopping you extending this logic with the UD flags if you wish and writing your own routines with what to do with the deletes - It all depends on how efficient you can identify rows that have been deleted.

How to delete some date in target table at a mapping?

How to delete some date in target table at a mapping?
I extract date from source tabel into target table,
but before extract date I want to delete some date from target?
how to do?

Just to change a bit of terminology in the reply, within the mapping, click on operator properties and choose TRUNCATE/INSERT.
Note that truncate is dependent on constraints, so you probably must disable those before doing this. You can of course do DELETE/INSERT...

How to soft delete a row from the target table?

Could someone help me on this requirement?
How to implement the below logic using only ODI? I am able to implement the below logic with the "DELETE_FLAG" as "N".
I want to make the latest record with the flag as "N" and all the previous other records with the flag as "D".
Thanks a lot in advance.
I have a source table "EMP".
EMP
EMPID FIRST_NAME
1 A
2 B
First name is changed from A to C and then, C to D etc. For each data change, I would add a target row and mark the latest row as "N" and the rest as "D". The target table would contain the following data:
Target_EMP
EMPID FIRST_NAME DELETE_FLAG
1 A D
1 C D
1 D N

The problem is that I can't delete the row cause it demands from me to fill the mandatory field previously. It takes place when the key field is ROWID. In other cases delete is succesful.

How to populate rows in the detail table of a form from another table.

please can someone help me here:
i have a master/detail page. the master data is created and then i would like to do this: when one goes to the detail page (when first created), i would like somehow to populate all the rows in the detail table from rows retrieved in another table (with conditions).
i am new to apex so if this is a stupid question i apologise in advance!

Hi
Firstly, there are no stupid questions, we all start somewhere!
However, I could do with some more detail (or even better an example on apex.oracle.com). Please can you post exactly what you have so far and what you want to achieve with simple details of the tables involved.
It sound like you may need to create a custom process to populate the details. You say 'with conditions'... what conditions?
Cheers

How to sort columns in the target table

I have a simple mapping which I am trying to design. There's only one table on the source and one in the target . There are no filter conditions, only thing is I want the target table to be sorted.
Literally, say
Src is source table has 3 columns x,y,z
Trg is dest table and has 3 columns a,b,c
x--->a
y---->b
z---->c
The SQL should be
select x,y,z from src order by x,y.
I could do the mapping but the order by ..I could not do it .

How to gather stats on the target table

Hi
I am using OWB 10gR2.
I have created a mapping with a single target table.
I have checked the mapping configuration 'Analyze Table Statements'.
I have set target table property 'Statistics Collection' to 'MONITORING'.
My requirement is to gather stats on the target table, after the target table is loaded/updated.
According to Oracle's OWB 10gR2 User Document (B28223-03, Page#. 24-5)
Analyze Table Statements
If you select this option, Warehouse Builder generates code for analyzing the target
table after the target is loaded, if the resulting target table is double or half its original
size.
My issue is that when my target table size is not doubled or half its original size then traget table DOES NOT get analyzed.
I am looking for a way or settings in OWB 10gR2, to gather stats on my target table no matter its size after the target table is loaded/updated.
Thanks for your help in advance...
~Salil

Hi
Unfortunately we have to disable automatic stat gather on the 10g database.
My requirement needs to extract data from one database and then load into my TEMP tables and then process it and finally load into my datawarehouse tables.
So I need to make sure to analyze my TEMP tables after they are truncated and loaded and subsequently updated, before I can process the data and load it into my datawarehouse tables.
Also I need to truncate All TEMP tables after the load is completed to save space on my target database.
If we keep the automatic stats ON my target 10g database then it might gather stats for those TEMP tables which are empty at the time of gather stat.
Any ideas to overcome this issue is appreciated.
Thanks
Salil

How to load data dynamically into target tables using files as a source

Hi ,
My scenario needs a single interface to load the data of 5 different files into five target tables using a single interface. All target tables have the same structure. It is possible to point to variable source files using ODI. But the same approach is not working with Database tables. I am getting errors while trying to make my target /source table as a dynamic one.
Can anybody suggest anything. The last option would be writing a dynamic PL/SQL block in the KM. Any other suggestions friends ?
Regards,
Atish

After creating a pair of identical source and target tables, I have carried out the following steps:
I am trying just keeping the target as variable
a)created a one to one interface,
b)tested that it is running.
c)created a variable(type =text),
d)used the variable as #v_name in the resource of the target table datastore.
e)in a package used the variable in a set variable step (first step).
f) used the interface as the second step.
g)executed the same in my context.
the <project_code>.variable_name is not getting substituted in the sql_code that is generated by the KM. My KM is SQL Control Append and following is the code that it generates in the Insert into I$ step:
/* DETECTION_STRATEGY = NOT_EXISTS */
insert /*+ APPEND */ into HR.I$_JOBS_COPY1
     JOB_ID,
     JOB_TITLE,
     MIN_SALARY,
     MAX_SALARY,
     IND_UPDATE
select
     JOBS.JOB_ID     JOB_ID,
     JOBS.JOB_TITLE     JOB_TITLE,
     JOBS.MIN_SALARY     MIN_SALARY,
     JOBS.MAX_SALARY     MAX_SALARY,
     'I' IND_UPDATE
from     HR.JOBS JOBS
where     (1=1)
and not exists (
     select     'X'
     from     HR.#PLAYGROUND."v_tab_name" T
     where     T.JOB_ID     = JOBS.JOB_ID
          and     ((JOBS.JOB_TITLE = T.JOB_TITLE) or (JOBS.JOB_TITLE IS NULL and T.JOB_TITLE IS NULL))
          and     ((JOBS.MIN_SALARY = T.MIN_SALARY) or (JOBS.MIN_SALARY IS NULL and T.MIN_SALARY IS NULL))
          and     ((JOBS.MAX_SALARY = T.MAX_SALARY) or (JOBS.MAX_SALARY IS NULL and T.MAX_SALARY IS NULL))

How to delete rows in the SQL Server table based on the contents of Excel file

Hello, everyone,
I have an Excel file which contains data for certain dates. I need to load it in a SQL Server table. But before doing that, I need to check if the table already contains data for the dates in the Excel file. If it does, I need to delete those data
first. Not sure what is the best and efficient way to do this. Your help and guidance would be much appreciated.
Thank you in advance.

there are multiple ways of doing this
Fastest method would be below
1. Have a data flow task using excel source. Then add a OLEDB destination to dump the data to a staging table
2. Have a Execute sql task to delete data from your actual table based on staging table data. The query would look like
DELETE t
FROM YourTable t
WHERE EXISTS (SELECT 1
FROM StagingTable
WHERE DateField = t.DateField)
3. Have another execute sql task to do final insert like
INSERT YourTable (Col1,Col2,...)
SELECT Col1,Col2,..
FROM StagingTable
the above operations will be set based and faster

How to update fields in the target table in correspondance with the source file values

Environment: win7, SQL server 2008 R2
Application: Microsoft Management SQL Studio 2008 R2, Business Intelligence 2008 - SSIS
SSIS competency level: Novice
Problem: I have been trying to update some of the fields in the destination table,student table, in reference to data set in the staging table and ssn table. I was able to insert/load new data to the destination using look up transformation
while the driver is ssn (data mapping) but i couldn't know how to update some of the fields in the student table while keeping the orignal pn_id of both tables(ssn and student tables), because pn_id already exists in the SSN table and student table. There
are other records also associated with the pn_id so I am not allowed to update the pn_id in the destination tables. For example,
SSN Table (pn_id,ssn)
('000616850',288258466)
('002160790',176268917)
Staging Table (ssn, id, pn_id, name, subject, academic year, comments)
(288258466, 1001, '770616858',Sally Johnson, English,A, 2005,'great student')

(1001, '000616850', ' ',' ', ,'')
(1002, '002160790', ' ',' ', ,'')
Expected Results:
My goal is to have student table updated as the following:
Student Table
(1001, '000616850', 'English','A' ,2005 ,'great student')
(1002, '002160790', 'Math ',' C',2014 ,'no comments')
please advise

Why can't you use simple UPDATE command in EXECUTE SQL Task as below,
DROP TABLE SSN
DROP TABLE STAGING
DROP TABLE STUDENT
CREATE TABLE SSN(pn_id VARCHAR(100),ssn BIGINT)
INSERT INTO SSN VALUES('000616850',288258466)

How to find a dependent row in the all tables using single SQL query

hi all,
I have created some table with master and some dependent tables.I want to mark a (row)tuple as inactive in master so that corresponding child records also should be marked as inactive.
So i decided to mark the master and dependent records as inactive starting from master table and traverse to child tables.
So I need SQL query to fetch all dependend records to the row(marked row in the master ) from the master table and dependent rows from the child row and to mark as flag inactive.
can anybody help me out to build this query or any other way to mark flag as inactive ?
Regards
punithan

You can find dependant tables from ALL_CONSTRAINTS, e.g:
SQL> CREATE TABLE m (id INT PRIMARY KEY, flag VARCHAR2(1) NOT NULL);
Table created.
SQL> CREATE TABLE d1 (m_id REFERENCES m, flag VARCHAR2(1) NOT NULL);
Table created.
SQL> CREATE TABLE d2 (m_id REFERENCES m, flag VARCHAR2(1) NOT NULL);
Table created.
SQL> SELECT table_name, owner, status
2 FROM   all_constraints c
3 WHERE c.constraint_type = 'R'
4 AND    ( c.r_owner, c.r_constraint_name ) IN
5         ( SELECT owner, constraint_name
6           FROM   user_constraints
7           WHERE table_name = 'M'
8           AND    constraint_type IN ('U','P') );
TABLE_NAME                     OWNER                          STATUS
D2                             WILLIAMR                       ENABLED
D1                             WILLIAMR                       ENABLED
2 rows selected.There is no SQL command to apply all updates in one go, if that's what you were looking for.
AFAIK the word "tuple" is for mathematics and relational theory, and does not refer to a physical row in a database.

And how do you imagine this happening with sqlloader?
The entire purpose of sqlloader is to load data (hence, the name sql*loader*) into a table from an external source. If you want to delete rows from a table, you use the sql DELETE statement.

Issue with INSERT INTO, throws primary key violation error even if the target table is empty

Hi,
I am running a simple
INSERT INTO Table 1 (column 1, column 2, ....., column n)
SELECT column 1, column 2, ....., column n FROM Table 2
Table 1 and Table 2 have same definition(schema).
Table 1 is empty and Table 2 has all the data. Column 1 is primary key and there is NO identity column.
This statement still throws Primary key violation error. Am clueless about this?
How can this happen when the target table is totally empty?
Chintu

Nope thats not true
Either you're not inserting to the right table or in the background some other trigger code is getting fired which is inserting into some table which causes a PK violation.
