How to jump a line to insert in the staging table
Hello worldI'm actually transform data from a source table in the staging table and staged, and then at the final table. I generated a primary key using the sequence. As I put the insert method of the staging table as truncate/insert. So whenever the mapping is loaded, intermediate table is truncated and new data are inserted but as I am with sequence of intermediate table, it will give the new numbering of old data from the source table and it will be duplicated data in the target table. So for this reason I use key look up on top of some attributes of entry and that the use of expression that I try to avoid duplication. At each exit of the attributes in the expression, I'm trying the case statement
"BOLD" CASE WHEN INGRP1. ROW_ID IS NULL
THEN
INGRP1.ID
END * bold *.
Because of this condition, I get the error message
"BOLD"
Warning
ORA-01400: cannot insert NULL into ('SCOTT'. "" "" STG_TARGET_TABLE '. "" ROW_ID")
"BOLD"
But I'm stuck when the row_id value is zero, that that condition or statement should I write to jump the insertion of data. I want to insert data only when ROW_ID IS NULL.
Kindly help me.
Thank you

You do not need identical tables to use LESS, only the 'select list' must match. Assuming you have the key of the enterprise (one or more columns that uniquely identifies a row of your data source) in the source and the final table, you can do the following:
-Use a Set operation where the result is the key to the business of staging table LESS the key to the business of the final table
-The output of the set operation is then joined to the staging table to get the rest of the attributes for these lines
-The output of the join is inserted into the final table
This will ensure that the lines with the new keys to the company are responsible.
Hope this helps,
Roald

Read data from table of $ E and insert in the staging table
Hi all
I'm new on ODI. I need your help to understand how to read data from a table ' E$ "and insert in an intermediate table.
Scenario:
The name of two columns, in a flat file, the employee and the employee id must be loaded into a data EMPstore +. A check constraint is added so that the data with the employee names in capital letters only to load in the data store. Check the command is set to the static movement . Right-click on the data store, select control , then check. The lines that have violated the check constraint are kept in E$ _EMP+ table.
Problem:
Problem is I want to read the data in the table E$ _EMP+ and transform in capital letters in the name of the employee and move the corrected data of E$ _EMP+ EMP+. Please advise me on how to automatically manage the 'soft' exceptions in ODI.
Thank youIf I understand, you want to change the columns in the tables of $ E and then load into the target.
Now, if you notice how ODI recycles the error, there is an incremental update to the target using the E table $ after he filled the I$ table.
I think you can do the same thing by creating an interface using the table of $ E as source and implement the business logic in this interface to fill the target.

How to jump a line with dynamic text in AS2
Hello!
I have another question, how skip a line using dynamic text? I want to do the following:
-DYNAMIC TEXT-

-THE END OF THE DYNAMIC TEXT.
I tried the following:
_root. RLinfo = ' - Info--

I get an error.
This:
_root. RLinfo = "-Info- asdasfasfsa"
He will only jump 1 line.
This is probably a very stupid question and has probably been answered a 1000000 times but I am too lazy to google it.

updated line and insert them into another table with trigger.
Hi guys I have a table that looks like this.
I'm going to insert the col1 and col2 values, but I need to get the value of column 3 of table 2 and then insert the complete record in table 3. I love doing that with a trigger. I get an error message and I can't for the life of me figuere out what im doing wrong.CREATE TABLE TEST ( "COL1" VARCHAR2(20 BYTE), "COL2" VARCHAR2(20 BYTE), "COL3" VARCHAR2(20 BYTE) )
So here is my nonfunctional trigger.
Here are the two table
HERE IS THE CODE OF THE TRIGGERCREATE TABLE TESTTABLE ( "COLUMN1" NUMBER(15,0), "COLUMN2" NUMBER(15,0) ) Insert into TESTTABLE (COLUMN1,COLUMN2) values (1,5);
I get an error of trigger mutation that I tried the other iterations of the above but I'm not getting anywhere. I have dumb down my problem at these 3 table.CREATE OR REPLACE TRIGGER TRIGGER1 AFTER INSERT ON TEST FOR EACH ROW BEGIN update TEST SET COL3 = (SELECT COLUMN2 FROM TEST, TESTTABLE WHERE COLUMN1 = :new.COL1); END
Can someone point me in the right direction.You'll have to do some reading, but it comes down to process the data on education instead of line level.
You may even be not at all a trigger.

How to update or insert for the fa_distribution_history table?
I need to change the location of an asset code when it changes its physical location. I looked in the tables and this change of assignment / location change updates and inserts a record in the fa_distribution_history table. I looked at a few documents, and there is a package called fa_distribution_history_pkg with the Update and Insert methods.
The question I have is changing the assignment, that I have to update the record of the old assignment and then create one with the new assignment?
Please let me know how I should proceed.
Thank you.Hello.
You should not use the package "fa_distribution_history_pkg" directly from your custom code.
The ideal way is to use the public APIs provided by Oracle. In this case, you should use is FA_TRANSFER_PUB.do_transfer.
Please try this one and advise if you are having trouble.

How to remove empty lines of chain between the relevant data?
I have problems with the removal of empty lines of final my data output string. I know this is simple to do, but I'm stuck in the same train of thought. The file is a converted hex file that is written in a series of recordings. Convert lines it is result in fa all that data should be deleted and the number of records adjusted accordingly. I have the code to take the file, convert, delete all of the records with F and adjust the number of files, but I'm left with a gap in my file no matter my approach I can't remove the empty spaces regularly. I have attached the file with spaces and the goal is to remove the spaces between the blocks of code, and spaces is not always in the same direction. Thanks for any help. If needed I can join the code I already developed if necessary.
Darrick
You can read the file line by line and write back only if the length of the string <> 0. (or maybe <> 1 in the case of the character line appears in the string to a blank line.)
However, there is probably a way to change the code you have now so that he does not write blank lines. Without seeing the code, it is difficult to help.

Why multi-threaded INSERT on the same table cannot work in a single connection
Environment: Win2k3, oracle10g, .net 2.
I tried the two roads, insert into a table with 20 columns. The code cannot be run directly, it describes just my thought. Note * [Q n] * and answer me please.
1. all OracleCommands share a single connection
main()
{
CNN OracleConnection = new OracleConnection;
[] Ths thread = new Thread [32]; 4 thread per CPU
for (int j = 0; j < ths.) Length; j ++)
{
Thread th = ths [j] = new Thread (proc);
FPE Start (CNN).
}
}
the static object sync_obj = new object();
Sub proc (object param)
{
OracleConnection cnn = param as OracleConnection;
OracleCommand cmd is cnn. CreateCommand();
cmd.CommandText =...; Insert statement on a specific table, using parameters
Lock (sync_obj) / / * [Q1] *: why lock is necessary? Deleting the line will result in ORA-01036 occasionally, details at the end
{
cmd ExecuteNonQuery());
}
}
2. a connection by OracleCommand
main()
{
[] Ths thread = new Thread [32]; 4 threads per processor
for (int j = 0; j < ths.) Length; j ++)
{
Thread th = ths [j] = new Thread (proc);
Th. Start();
}
}
Sub proc (object param)
{
CNN OracleConnection = new OracleConnection;
OracleCommand cmd is cnn. CreateCommand();
cmd.CommandText =...; Insert statement on a specific table, using parameters
* [Q2] *: why the lock is useless for a successful run?
cmd ExecuteNonQuery());
}
* [T3] * is it true that INSERT statement does not engage the table of data at all?
* [T4] * as shown in the code, it is the rule that a single INSERTION in a same table capable of running at the same time in a single connection?
In fact, I want to insert thousands of records to a table, each thread can insert several hundred.
I appreciate if you can provide a detailed answer and I am very happy that you can send the answer to [email protected] , because I check the email more frequently than the OTN forum.

Select values from the db1 table and insert into the DB2 table
Hello
I have three databases oracle running in three different machines. their ip address is different. among the DB can access databases. (means am able to select values and insert values into tables individually.)
I need to extract data from the DB1 table (ip say DB1 is 10.10.10.10 and the user is DB1user and the table is DB1user_table) and insert the values into DB2 table (say ip DB2 is 11.11.11.11 and the user is DB2user and table DB2user_table) of DB3 that is to have access to the two IPs DB.
How do I do this
Edited by: Aemunathan on February 10, 2010 23:12Depending on the amount of data must be moved between DB1 and DB2, and the frequency at which this should happen, you might consider the SQL * COPY more control. I think it's very useful for one-off tasks little, so I can live within its limits of the data type. More http://download.oracle.com/docs/cd/E11882_01/server.112/e10823/apb.htm#i641251.
Change some parameter of sqlplus session are almost mandatory in order to get decent transfer rates. Tuning ARRAYSIZE and COPYCOMMIT can make a huge difference in flow. LONG change may be necessary, too, depending on your data. The documentation offers these notes on use:
To activate the copy of data between Oracle and databases non-Oracle, NUMBER of columns is replaced by DECIMAL columns in the destination table. Therefore, if you are copying between Oracle databases, a NUMBER column with no precision will become a DECIMAL column (38). When copying between Oracle databases, you must use SQL commands (CREATE TABLE AS and INSERTION), or you must make sure that your columns have a specified precision.
SQL * the VALUE LONGER variable limits the length of the LONG column you are copying. If all LONG columns contain data exceeds the value of LONG, COPY truncates the data.
SQL * Plus performs a validation at the end of each successful COPY. If you set the SQL * variable more COPYCOMMIT DEFINED to a value positive n, SQL * Plus performs a validation after copying all lots n of records. The SQL * Plus ARRAYSIZE variable SET determines the size of a batch.
Some operating environments require that the service names be placed between double quotes.
From a SQL * Plus term on DB3, can resemble the command to move all content from my_table in DB1 to the same table in DB2
COPY from user1/pass1@DB1 to user2/pass2@DB2 - INSERT INTO my_table - USING select * from my_table
Note the SQL code * more line-continuation character ' - '. It is used to escape the newline character in a SQL * Plus command if you do not have to type all on one line. I use it all the time with this command, but I can't locate the documentation on that right now. Maybe someone else can put their finger on it.
There are other ways to accomplish what the command copy and it is not without its quirks and limitations, but I find that there is usefulness in an Oracle Toolbox.

insert into the summary table of the table.
I was wondering if there is a smart way to do it with SQL, but I'm not sure. I would like to consult you yo guys.
I have a table like this
I would like to at the rate of an update and you end up withCREATE TABLE "TEMPLE_FINANCE"."TEST" ( "COLUMN1" VARCHAR2(10 BYTE), "COLUMN2" VARCHAR2(10 BYTE), "COLUMN3" VARCHAR2(10 BYTE), "COLUMN4" VARCHAR2(10 BYTE) ) ; Insert into TEST (COLUMN1,COLUMN2,COLUMN3,COLUMN4) values ('1','2','50.00',null); Insert into TEST (COLUMN1,COLUMN2,COLUMN3,COLUMN4) values ('1','2','50.00',null);
What update statement can run for this?"COLUMN1" "COLUMN2" "COLUMN3" "COLUMN4" "1" "2" "100.00"
I would enter in the summary of the lines based on the column 1 and column2 and get rid of repeative lines.
I have try this insert statement, but it's bascially just adding an extra record in the table.
any help would be grateful.INSERT INTO TEST (SELECT COLUMN1, COLUMN2, SUM(COLUMN3), COLUMN4 FROM TEST GROUP BY COLUMN1, COLUMN2,COLUMN4);

Published by: mlov83 on January 25, 2013 13:03Hello
I can't help but wonder if you have the best design of table for what it is, you need to do.
The best solution would be to create a new table, using the SUM (TO_NUMBER (Column3)) and GROUP BY, and then delete the original table and rename a new one to the old name. While you're at it, change Column3 as a NUMBER and add a primary key.
In collaboration with just the existing table, INSERT one won't work. INSERT always adds new lines. You want something that can INSERT new lines (or update some existing routes) and DELETE lines at the same time. FUSION can do it all. Here's a way to use the MERGE:
MERGE INTO test dst USING ( SELECT column1, column2, column4 , SUM (TO_NUMBER (column3)) OVER (PARTITION BY column1, column2, column4) AS column3_total , ROWID AS r_id , MIN (ROWID) OVER (PARTITION BY column1, column2, column4) AS min_r_id FROM test ) src ON (src.r_id = dst.ROWID) WHEN MATCHED THEN UPDATE SET dst.column3 = TO_CHAR ( src.column3_total , 'FM9999999.00' ) DELETE WHERE src.r_id != src.min_r_id ;

Logging what data inserted in the outer table
Hello
We load a large number of data using external tables and inserts into tables partitioned by day nor the hour.
Other parts of the system want to know what partitions have been updated and when, so before load us all the data, we make a
That's when inserting into partitions of day, IE get all separate days of that specific file.insert into new_data(date_of_event) values (select distinct(trunc(date_of_event) from external_table)
These files, however, can be very substantial and after this first analysis, we do a full insertion in to the correct data table, that is, read the entire file again.
So my question is, is there another (better) way to retrieve the different days/times? A way to make the effective insertion in the table of data and information on which partitions Oracle inserted data into any dictionary etc.?
Haven't tried creating a 'good' temp-table, insert the data into it, extraction of dates and then inserting to the actual data table. But then, what is the best, creating a table and a fall or read the file twice?
Thanks in advanceYou don't say how you are querying and inserting, but if you have a control on a few possibilities come to mind.
1. use INSERT ALL make a multi-table insert. Insert the "date_of_event" into a new "Journal" table and insert data to the table that you insert now.
Then you can make the separate (trunc (date_of_event) "select" on the new table of newspaper. Just truncate the new log table before each query or add a column that contains the file that was imported.2. create a VIEW that includes all the columns in your current query and another copy of "date_of_event" and peel the date of the event in another table.
Option #1 is the simplest.

BULL, INSERTION IN THE PARENT TABLE AND THE CHILD TABLE
Hi all
We use bulk insert to improve performance. How to use this concept when I insert the records parent in table parent and child?
example... I have a procedure that accepts the array of student objects
each student object is defined as *(student name, student age, course_object_array) *.
the 3rd element course_object_array is defined as *(coursename,course fee,facultyname) *.
a student can be associated with several courses
Now, I have to insert the data into two tables namely students (studentname, studentage and student_number)
courses (course_id, coursename, fees, facultlyname, student_number)
I use sequences to fill the columns student_number and course_id.
If I use bulk insert, and insert all the records in the parent table how do I the association for each record of a child. How will I know what child folder must be associated with which of the parents?

Hi thanks for the reply Solomon.I actually know about the bulk collect and for all...
Have you read that FOR ALL with in fact BULK COLLECT? It will allow you to bulk insert via for ALL with VOTING student_numbers attributed to each student placed in a collection. Then, you will use this collection collection of course list to fill the RACE table.

Record is not inserted into the transparent Table Forms 10g
Hi all
I have the built in 10g (10.1.2.0.2) form.
Basically, the form has 2 blocks.
1 block with a single element, where we enter a value and press on enter (this place you block2 and run the query).
Block 2 (tabular) will get the records. This block2 have now 3 columns (caseid, userid, date).
Now when I insert a new record, I just need to get the caseid only. And username and date must be filled in automatically.
I can fill fields username and the DATE.
And when I enter a value element of the block 2 caseid and then Control + S(to insert the record and Save the transaction),.
I get the message saying FRM-40400: transactions: 1 applied and saved records.
But when I ask again for the same thing, I do not have is the record inserted into the table.
Why is this happening?
Help please...Drop the trigger for INSERTION WE (do not comment code or write NULL) and move your code to INSERT before trying.
