on cidcb_cac
begin
raise_application_error( -20001, 'You are not allowed to DROP or TRUNCATE table in this schema. ' );
end;
I am try to build a triger so that no one can delete truncate or delete my table in schema but it is showing me error when i m executing it...
ORA-30506: system triggers cannot be based on tables or views
i think i am wrong in writing this query ...can someone guied me in creating this kind of trigger ...i am a user in oracle not administrator......
so how can show error if someone try to do with my table in my schema like HR
thanks in advance....:)
using oracle 10.2g SE

You cannot define a trigger of system level (drop, truncate) on a table since they are not DML, but DDL. These commands should be defined at schema level.
Please, take a look to the trigger doc

Use of "DBA_OBJECTS" in "AFTER CREATE" Trigger

Hi,
We would like to store some extra information about our objects we have in the database. To do so we tought of the idea of creating a 'documenting' table containing an object_id that references to the object_id from the view dba_views.
Now we want to automatically create a new record in our documenting table when a new object is created, in the first stage this should only contain the object_id
To accomplish this we are using an 'AFTER CREATE' trigger, but when this trigger fires and the code searches for the new object_id in dba_objects, it does not return any records and generates an error. Likely because when the trigger is executed, the view is not yet updated?
create or replace
TRIGGER TRG_TEST
AFTER CREATE ON SCOTT.SCHEMA
DECLARE
tmp VARCHAR2(50);
BEGIN
dbms_output.put_line(ora_dict_obj_name);
select object_id
into tmp
from dba_objects
where object_name = ora_dict_obj_name;
dbms_output.put_line(tmp);
END;
Error report:
ORA-04088: Fout bij uitvoering van trigger 'SCOTT.TRG_TEST'.
ORA-01403: Geen gegevens gevonden.
ORA-06512: in regel 6
04088. 00000 - "error during execution of trigger '%s.%s'"
*Cause:    A runtime error occurred during execution of a trigger.
*Action:   Check the triggers which were involved in the operation.
It's in dutch, so I'll have a go at translating:
Error report:
ORA-04088: Exception while executing trigger 'SCOTT.TRG_TEST'.
ORA-01403: No data found
ORA-06512: in rule 6
04088. 00000 - "error during execution of trigger '%s.%s'"
*Cause:    A runtime error occurred during execution of a trigger.
*Action:   Check the triggers which were involved in the operation.
Does anyone have an idea of how I can accomplish what I'm trying to do here.. Or maybe something I'm doing wrong?
Thanks in advance!

What is "ora_dict_obj_name" defined as?
Another option might be to setup a DBMS_SCHEDULER job to run the following insert
firstly though, create the following table ;
create document_table as (select * from dba_objects where rownum < 1)and then setup a DBMS_SCHEDULER job to run the following:
begin
insert into document_table
(select dbo.*
   from   dba_objects    dbo
         ,document_Table dtb
   where dbo.Object_ID = dtb.Object_ID(+)
   and    dtb.Object_ID is null);
   commit;
   exception
    when others then
      rollback;
      -- log a message somewhere with the error, i.e. SQLERRM
end;
/Note, I specified all columns, but you'll probably specify explicitly which column you require, in which case the CREATE table would change as well.
Then you won't have a need for any trigger, and can better manage when you want your documentation to be updated.
Another option might be to use COMMENT, which can be used on tables, views, materialized views, but won't cover all objects
to the extent you might want.

Execute create trigger script in a procedure

Is it possible to create a trigger with pl/sql?
I have made a procedure thats makes the create or replace trigger statement.
(when i copy and past the statement the trigger is created succesvol)
How can i execute the create trigger statement on the end of the procedure?
Thanks.

Well, then proceed with dynamic SQL.
Or, in my opinion much better: produce a SQL script with variables for table name and trigger name.
Then run this script with the appropriate values every time you have created a table.

Create trigger on view belong to different schema of same db

Hi Guru's,
I have two different schema in the same DB.
Example : schema1 and schema2
I have one view on schema1 and i have grant select to schema2 and create synonym for that view.
Now i need to create trigger on synonym which created from view in schema1 and insert the data into different table from trigger when insert happen on view.
first of all , is it possible?
if its possible then do i need to give create any trigger on view to schema2.
Or is there any other we can get this done..
Many thanks.

Triggers operate on tables and views (but I'll just say "table" from now on). It doesn't matter if the statement that caused the trigger to fire used the actual table name or a synonym.
which created from view in schema1 and insert the data into different table from trigger when insert happen on view.
first of all , is it possible?I'm not sure I understand you here, either.
It is possible to have a trigger on a view in schema1, which INSERTs data into a table. That table can be in any schema, just so long as the trigger owner has privilges on INSERT into it.
if its possible then do i need to give create any trigger on view to schema2.It's very dangerous, and usually a terrible idea, to grant the CREATE ANY privileges to users.
Schema2 needs the CREATE ANY TRIGGER system privilege only to create a trigger in another schema, such as schema1. There's probably no reason to do that. Let schmea1 create the objects in its own schema.
Post a test script that shows what you want to do. Include CREATE TABLE, CREATE VIEW, CREATE TRIGGER, CONNECT and INSERT statements, and the results you want (the contents of tables where the trigger INSERTed data). If you don't know how to code something, post the closest thing you can, and explain what you really want to do in that place.

Error in Creating Trigger

Hi All,
I have a problem in creating a trigger.
I have two fields named last_updated_by, last_updated_date which
r common to all the tables.
If the user made any change to the exiting record, the values of
the those two colums should get changed automatically with the
username and sysdate.
When I wrote a trigger its giving mutation error.
Can I update these value by stored procedure via trigger?
I heard its possible by DBMS_JOB package. Can anyone give idea?
Thanks in Advance.
Regards
Gopinath Kona

You should only get the mutating table probllem if you're doing
SELCT or DML against the table the trigger's built on. Which
suggests that you're approaching this the wrong way.
Try CREATE TRIGGER blah blah
FOR EACH ROW
:new.last_updated_by := USER;
:new.last_updated_date := SYSDATE;
END;
If that's what you are doing then the problem lies elsewhere.

Error while create trigger on for nested table

I want to insert a record into a nested table.For this, I created a view for the table, which includes the nested table.It told me ORA-25015 cannot perform DML on this nested table view column.So I created a trigger for the nested table.However, it told me that ORA-25010 Invalid nested table column name in nested table clause.I think my nested table is valid, i don't konw why did it appear this kind of problem?
My table is
CREATE TABLE ENT
ID NUMBER(7) NOT NULL,
CREATE_DATE VARCHAR2(11 BYTE),
UPDATE_DATE VARCHAR2(11 BYTE),
DEPTS VARRAY_DEPT_SEQ
CREATE OR REPLACE
TYPE DEPT AS OBJECT
ID NUMBER(8),
ANCHOR VARCHAR2(20),
CREATE OR REPLACE
TYPE " VARRAY_DEPT_SEQ" as varray(930) of DEPT
CREATE OR REPLACE VIEW ENT_NESTED_VIEW
(ID, CREATE_DATE, UPDATE_DATE, DEPTS)
AS
select e.ID,cast(multiset(select r.id,r.anchor from ent z, table(z.depts) r where z.ID=e.ID )as varray_dept_seq)
FROM ENT e
Then when I created trigger;
CREATE OR REPLACE TRIGGER EMP.ENT_NESTED_TRI
INSTEAD OF INSERT
ON NESTED TABLE DEPTS OF EMP.ENT_NESTED_VIEW
REFERENCING NEW AS New OLD AS Old PARENT AS Parent
FOR EACH ROW
BEGIN
END ;
I met the problem: ORA-25010 Invalid nested table column name in nested table clause
Could you please tell me the reason
Thank you!
My insert SQL is:
insert into table(select depts from ent_nested_view where id=1856) values(varray_dept_seq(dept(255687,'AF58743')))

Hi,TongucY
Compared with the "Referencing Clause with Nested Tables" part of this reference -
http://psoug.org/reference/instead_of_trigger.html, I found the answer of this
quesion. That is "CREATE OR REPLACE TYPE " VARRAY_DEPT_SEQ" as[b] varray(930) of
DEPT". It turns to be a varying array, not a nested table. It should be "CREATE OR
REPLACE TYPE " VARRAY_DEPT_SEQ" as table of DEPT". That is OK. Thank you very
much!
While there is an another question, if I create a varying array like" CREATE OR
REPLACE TYPE " VARRAY_DEPT_SEQ" as[b] varray(930) of DEPT " and I want to insert
a record into the varying array, which the record has been existed.The method that
create a view and a trigger seems not to be effective.
For instance,
There is a record in the table
ID:1020
CREATE_DATE:2005-10-20
UPDATE_DATE:2007-2-11
DETPS: ((10225,AMY))
I want to ask this record to be
ID:1020
CREATE_DATE:2005-10-20
UPDATE_DATE:2007-2-11
DETPS: ((10225,AMY),(10558,TOM))
How should I do?
Could you please help me?
Best regards.

Bad bind variable error on creating trigger

hi
im trying to create a trigger on a table in Oracle and I keep gettin this error:
PLS-00049: bad bind variable 'NEW.ID'
TeamID is a primary Key, it creates the sequence fine, but i get the error on the create trigger,
CREATE TABLE TBLTEAMS
TEAMID NUMBER(5),
NAME VARCHAR2(50 BYTE),
MANAGER VARCHAR2(50 BYTE),
COSTCENTRE NUMBER(9),
PARENTTEAMID NUMBER(5)
create sequence seq_Teamsautonumber;
create trigger trg_Teamsautonumber
before insert on tblteams
for each row
begin
select seq_Teamsautonumber.nextval into :new.id from dual;
end;
any ideas?

You have said
:new.idthat means you are trying to load the sequence value into a column that doesn't exist in your table.
you would need to use
:new.teamidAssuming you are trying to auto-populate the TEAMID column on your table.

What user interface are you using?
If the tool doesn't support the SQL*Plus syntax (set serveroutput on), it probably has an option somewhere to enable DBMS Output. Not even knowing what tool you're using, it's impossible for us to guess where that option might be configured.
As others have suggested, using DBMS Output to test code is less than ideal because you're dependent on the application you're using to display it to you and not every application can or will do that. If you want to use DBMS_Output, you may need to switch to a different GUI (SQL Developer or SQL*Plus are both free utilities from Oracle). Otherwise, you'd probably be better off having the trigger do something that you can subsequently query (i.e. write a row to a log table).

Create trigger not audited when run from sql developer Version 3.2.20.09

Creating or editing a trigger is not being stored in the audit table when run from sql developer.
Here is a sample script to show the issue:
Grant Connect,create table,create trigger To testuser Identified By testuser;
create table testuser.testtab(t1 number);
Select Count(*) From Dba_Audit_Trail Where Owner='TESTUSER';
CREATE OR REPLACE TRIGGER testuser.testtab_bi_trg BEFORE
Insert
ON testuser.testtab FOR EACH ROW
begin
null;
end;
Select Count(*) From Dba_Audit_Trail Where Owner='TESTUSER';
drop user testuser cascade;
If I run the script from sql developer the CREATE TRIGGER statement does not get audited.
If I run the script from sql plus or All Arround Automations PL/SQL Developer the CREATE TRIGGER statement does get audited.
If I edit the trigger from sql developer the CREATE TRIGGER statement does not get audited.
If I edit the trigger from All Arround Automations PL/SQL Developer the CREATE TRIGGER statement does get audited.

Have you tested my script? Does the "Select Count(*) From Dba_Audit_Trail Where Owner='TESTUSER';" increment by 1 after each of the ddl statements or only after the Create table statement.
Your question doesn't have ANYTHING to do with sql developer and should be posted in the Database General forum

Yes - and it works just fine once you ENABLE AUDITING. Your scripIt does NOT include the statements or code used to ENABLE auditing and, specifically, enable auditing for triggers.
Auditing doesn't just 'happen'; you have to enable it and you have to specify any non-default auditing that you want to perform.
Have you read any of the extensive documentation about auditing to learn how to use it?
See the Database Security Guide

Create Trigger (PK from Sequence) in SQL Developer 1.5.1

Hi all
I'm new to Oracle and am trying to create the equivalent of an autonumber field on a table using the Create Trigger (PK from Sequence) option (by right clicking on a table in SQL Developer).
I've set up a sequence called REQUESTID and when using the above option it generates the following SQL:
begin
execute immediate 'create or replace trigger AutoNumber '||
     ' before insert on "REQUEST" '||
     ' for each row '||
     'begin '||
     ' if inserting then '||
     ' if :NEW."REQUESTID" is null then '||
     ' select REQUESTID.nextval into :NEW."REQUESTID" from dual; '||
     ' end if; '||
     ' end if; '||
     'end;';
     end;
When I click Apply I get an ORA-00942 (table or view does not exist). Am I doing something daft here?

Never mind - sorted it - I created the table under a different Schema to the System login being used in SQL Developer and so didn't have the permissions to create the trigger on the table.

Multiple CREATE TRIGGER's in SQL file

I have an SQL file which contains multiple CREATE TRIGGER statements. I can't run it as it stands in SQLPlus Worksheet because it doesn't recognise the
end;
as the end of the create trigger statement and fails on the next CREATE line.
Is there a way I can get this file to process. I can run each statement individually, but there's a lot of them.
Any thoughts much appreciated.
Thanks in advance.

Just for clarity within your file, you may want to do the following
Create or Replace Trigger TG_One
before insert on mytab_two
for each row
declare
adt_exists EXCEPTION;
begin
end TG_One ;
Create or Replace Trigger TG_Two
before insert on mytab_three
for each row

adt_exists EXCEPTION;
begin

I write a Java programm to create a trigger(through JDBC connection). After I run the programm, a trigger was created in Oracle 10g.But the trigger is invalid. After Compiling the trigger , a error "PLS-00103 " occured .But if I excute the SQL in SQL developer,the trigger was created successfully.
If there is some special considerations should be taken when using programm to create trigger?
My Java programm fragment as follows:
     public void createTrigger() throws SQLException{
          Statement stmt = conn.createStatement();
          stmt.executeUpdate(getCreateTriggerSql());

Yes the special consideration is you shouldn't perform DDL on the fly, as it has all kinds of unwanted side effects like implicit commits.
If I would start a company, and I discover one of my developers is writing this kind of program, I would fire him, on the spot.
