Before insert Trigger and SQL Loader
Hi,
I have a table with a BEFOR insert on each row trigger . I am loading the data to that table using sqlloader and I want my trigger to fire for each row. But the trigger is firing only for alternate rows.
body of trigger as follows.
select max(pd_id) into VarVal from <table name> where tar_id=:new.tar_id;
select pd_id+1 into :new.pd_id from dual;
if I remove the first select statement from my trigger , then it is firing for all the rows. But the removel of first select statement will not satisfy my requirements.
So please suggest me how can I achieve this.

INSERTstatement is not working if there is a before insert trigger
INSERTstatement is not working if there is a before insert trigger on that table. That trigger contains an insert to another table which having the main table reference.
Let us say, for example there a table named 'EMP_DEPT' and there is a before insert trigger on this table.
In this trigger inserting a record in to another table named 'AUDIT_EMP' and in this table using EMP_Dept primary key as foreign key.
Table EMP_DEPT is having the below columns:
EMP_DEPT_SYS_ID
EMP_DEPT_NO
DEP_NAME etc..
Table AUDIT_EMP is having the below columns:
AUDIT_EMP_SYS_ID
EMP_DEPT_SYS_ID
AUDIT_NO etc..
the code in the trigger is
INSERT INTO audit_emp
(audit_emp_sys_id, emp_dept_sys_id, audit_no
VALUES (audit_emp.NEXTVAL, :new EMP_DEPT_SYS_ID, '1101'
Now when you execute the insert query like:
INSERT INTO emp_dept
(emp_dept_sys_id, emp_dept_no, dep_name
VALUES (EMP_DEPT.nextval, 1001, 'Dep-1'
It is giving the error saying 'Integrity constraint error, parent key not found' from the trigger.
But, when you modify the above insert query like the below then it is working.
INSERT INTO emp_dept
(emp_dept_sys_id, emp_dept_no, dep_name
SELECT EMP_DEPT.nextval, 1001, 'Dep-1'
FROM DUAL;
I am using Oracle 10g.
Why the insert into values is not working. Is there any commit transaction sequence change? Any idea please?
Edited by: user6475632 on Sep 16, 2009 7:08 AMObviously the code you posted can not work.
You are inserting the detail record (the audit record) before the master record, where it should have been after. IMO, you should fire the trigger AFTER INSERT for each row.
If that still doesn't work, you need to change the foreign key constraint into a deferred constraint, which is evaluated at commit, instead of immediately. The SQL reference manual has further info on this.
'Oracle 10g' is considered a marketing label here, not a -4 digit- version.

Problem while using Before insert Trigger
Hello everybody,
I am using 9.2.0.4.0 XMLDB..
The problem occurs while using the before insert trigger shown below to convert a CLOB(:new.file_clob) to XMLTYPE(:new.file_xml). The trigger is on a table with file_clob and file_xml as columns. file_xml column is based on a registered schema.
The trigger is:
Create or replace trigger po_2_demo_xml_tab_trg
before insert on po_2_demo_xml_tab
FOR EACH ROW
-- Step 1:to convert CLOB to XMLtype and store it
--in :new.file_xml .
:new.file_xml := xmltype(:new.file_clob);
-- Step 2:to verify if :new.file_xml has been created
dbms_output.put_line(:new.file_xml.extract('/PurchaseOrder/PONum/text()').getStringVal());
end;
If u insert a valid xml file, u can see the PONum value on dbms output(Step 2 of the trigger works). u also get the "1 row inserted" message.
Surpisingly, if u query on the table it shows that the file_xml column is null! For some reason, the value of :new.file_xml in the before insert trigger is not being retained in the table.
Has anybody encountered this before? Do I have to apply any patch?
Appreciate any help in this regard.
Thanks,
Partha.sorry! I just noticed.. the trace file does show an error, but the error is while creating the table itself.
Please see the segment from trace file below:
The following statements encountered a error during parse:
create table po_2_demo_clob_xml_tab
file_clob CLOB,
file_xml xmltype
)xmltype column file_xml
XMLSCHEMA "http://Friday/PO_2.xsd"
ELEMENT "PurchaseOrder";
XCTEND rlbk=0,
Error encountered: ORA-00911
But, inspite of this I am able to insert a xml file into file_xml using a sql statement. But the before insert trigger does not retain :new values.
Appreciate any comments.
Thanks,
Partha. -
Clob field not working in BEFORE INSERT trigger
Hello, everyone. I am trying to create a before insert trigger for a table (10g). I would like to create a value for a table field based on the xml query from a clob field. The table looks like this:
SQL> desc lac_costing_upload
Name Type Nullable Default Comments
UPLOAD_ID NUMBER Y
EMP_NUM VARCHAR2(20)
UPLOAD_DATE DATE Y
YEAR_MONTH VARCHAR2(10) Y
UPLOAD_TEXT CLOB Y
The trigger code looks like this:
create or replace trigger lac_cst_upl_yr_month
before insert on lac_costing_upload
for each row
declare
l_month varchar2(20);
l_year varchar2(20);
l_error_msg varchar2(255);
begin
SELECT XMLTYPE (:old.upload_text).EXTRACT('Oracle_Extract/Year/text()').getstringval() Extr_Year
, XMLTYPE (:old.upload_text).EXTRACT('Oracle_Extract/Month/text()').getstringval() Extr_Month
into l_year
, l_month
FROM dual;
:new.year_month := l_year || '.'
|| substr(l_month, 1, 3)
exception
when others then
l_error_msg := substr(sqlerrm, 1, 10);
:new.year_month := l_error_msg;
end lac_cst_upl_yr_month;
Here is a sample insert statement:
insert into lac_costing_upload lcu values(2006, '008925', sysdate, null
, '<Oracle_Extract>' || chr(10)
|| ' <Emp_Num>05417</Emp_Num>' || chr(10)
|| ' <Emp_Name>Fitzgerald</Emp_Name>' || chr(10)
|| ' <Year>2007</Year>' || chr(10)
|| ' <Month>May</Month>' || chr(10)
|| ' <Vehicle>1330</Vehicle>' || chr(10)
|| '</Oracle_Extract>'
My hope was to see '2007.May' in the year_month field. However, I'm getting 'ORA-06502:' instead. It looks like the value of :old.upload_text is null in the trigger.
Can anyone tell me what I'm doing wrong?
Thanks for any help.
--DaveThat's probably a really dumb error, but I don't work much with triggers.

Problem determining if id is present in BEFORE INSERT trigger
Hi,
I have written a BEFORE INSERT trigger in which I am trying to determine whether or not an id (primary key ) has been submitted as part of the insert. The reason for this is that in my application there are two cases in which the trigger will be called, 1) when the id has been previously obtained from a sequence and passed in, and 2) when an id needs to be 'automatically' generated from within the trigger'. (two subsystems which work differently talk to the database in different ways)
this is the key part of the trigger code:
CREATE OR REPLACE TRIGGER trg_submissions_seq_id
BEFORE INSERT on submissions
FOR EACH ROW
BEGIN
if :new.id IS NULL THEN
select seq_submissions_id.nextval INTO :new.id FROM DUAL;
end if;
....more code here
END;
I think this is correct. Can someone confirm this.
However the behaviour I see is that in case 1 the id is increased twice , once when it is obtained from the sequence , and then again in the trigger... despite the condition I put in.
If anyone can shed any light on this behaviour I would be grateful.
MarkThis trigger (at least what you've posted of it) won't increment the sequence if Rails passes in the ID column. If you're always seeing the sequence incremented twice, I would tend to wager that either Rails is calling the nextval function twice or that it is not passing in an ID. Of course, since Oracle sequence-generated values are not gap-free, presumably this is just a cosmetic issue, not a functionality issue.
As a general matter, I'd suggest not using ID as a column name for a table. In addition to being a poor naming convention, ID is a reserved word.

Before delete trigger and foreign key relationship
Hi,
I am analysing one database for migration. On one parent table there is before delete trigger , to delete records from child. Also there is foreign key relationship on child table for this parent table.
When I am deleting a row from parent, message gets displayed as "there are child records found."
I would like to know, if there is foreign key relatioship then delete trigger on parent does't work, what is exactly happening?Could you post that trigger code and the Oracle version as well?
With basic assumptions, I can't reproduce what you have stated here.

How to delete the Table Contents before inserting records into SQL table ?
Hello Experts,
I have a scenario where in I have to Pick up some records from SAP RFC & insert into SQL table.
i know how to do this scenario but the proble with this is before inserting we first have to ZAP the SQL table & insert a new records. One more twist is The Triggering is happening from SAP side with Sender RFC. If this would have been from SQL Side i could have written a Stored Procedure/ Trigger & could have called this before the SENDER JDBC communciation channel picks up the Triggering event from SQL side.
So how to do this scenarioin XI, First deleting all the Records of SQL table & then inserting the new reocrds. without using the BPM.
Regards,
Umeshhi umesh,
you can achieve this by writing SQL query in message mapping level..

hi all,
We have Oracle 10g RAC on IBM AIX
Today i will be uploading data in a table through sql loader.
I want that at the time of insertion only data which i am inserting goes into the table,As i am using sequence on particular column A.
Problem is If i shutdown database then i will not to able to insert data and if i doesnt shutdown db value for that column A is generated automatically when application works.
i have recommanded that we should stop connectivity of application with database then i will perform insertion but some people are saying no.Find other method
What steps should i do?Ok i thing my question was not clear
I have table XYZ
A B C
1 2 3
4 4 5
if application is connected to database value to Coulmn is incremented
A B C
1 2 3
4 4 5
5 6 7
i have to insert into table XYZ using sql loader giving sequence (4,1) on column A.
But if it is connected to application it will give me error of PK.
as Value 5 is already inserted by application so how can i stop this.
so that i can have the max value of coulmn and start sequence
Hope this time make u clear.
sorry for bad english -
Migrating from MSSQL2005: Before-Insert Trigger Generation
The SQL Server 2005 tables with auto=incrementer primary keys result in sequence objects being defined for use in Before-Insert triggers, which is good. I see the following code in the generated triggers:
<br>
IF INSERTING AND :new.ofi_service_provider_id IS NULL THEN
SELECT OFI_SERVICE_PROVIDER_ofi_servi.NEXTVAL INTO v_newVal FROM DUAL;
-- If this is the first time this table have been inserted into (sequence == 1)
IF v_newVal = 1 THEN
--get the max indentity value from the table
SELECT NVL(max(ofi_service_provider_id),0) INTO v_newVal FROM OFI_SERVICE_PROVIDER;
v_newVal := v_newVal + 1;
--set the sequence to that value
LOOP
EXIT WHEN v_incval>=v_newVal;
SELECT OFI_SERVICE_PROVIDER_ofi_servi.nextval INTO v_incval FROM dual;
END LOOP;
END IF;
</br>
I'm guessing this is a boilerplate template. I'd like to replace this with my own template code, so the generated triggers meet our own in-house specifications. And that looping method of bumping up a sequence object's NEXTVAL is hideous!
Is there a way to modify your template with my own, so I can generate the triggers according to our needs?
- Dan ClamageI'm trying to generate the code to fit our shop. These Before-Insert triggers would need to be rewritten for our environment. The template provided doesn't suit our needs. It'd make more sense if it was picked up from a text file, or at least presented on a Preferences screen, with placeholders for the sequence object name. Then a developer could tweak it to suit their own shop's needs, and have it generated correctly from the migration.
This migration isn't a one-time deal for us. We'd be doing it over and over. -
Request: PL/SQL, External Table and SQL Loader
I see lately Questions asked in SQL and PL/SQL forum regarding SQL Loader and External Table are being moved to {forum:id=732}.
Being an PL/SQL developer for some time now i feel External Table (and if i may, SQL Loader and DBMS_DATAPUMP) are very much an integral part of a PL/SQL development and the question related to these topics are well suited in SQL and PL/SQL forum. Even in SQL and PL/SQL FAQ we have exclusive content that discuss on these topics {message:id=9360007}

Oracle Replication and SQL*Load direct Path
We are setting up Oracle replication and have a few tables which are loaded using SQL*Loader Direct path. I have following questions:
1. Can MultiMaster replication replicate direct patch sqlloaded data.
2. If the answer to the above question is no, should we set up a new snapshot replication group . All other tables are in the Multi Master replication.
3. Another question is on the number of replication groups. How many of these we should create. We have total of about 500 tables and database size is about 450 Gig. We plan to replicate all the tables and the refresh interval we want to be one minute for all the tables. Does having more/less replication groups help??

Thanks for your help I believe what Oracle recommends is that you split up your tables into replication groups transactionally. I personally have 6 replication groups supporting 700+ tables. They are broken up more by business function than by number and size. -
