Before rename database trigger

Hi!
I have the following database trigger to catch
alter table ... rename to ... statements:
CREATE OR REPLACE TRIGGER CHECK_BEFORERENAME
BEFORE RENAME
ON DATABASE
BEGIN
END;
The problem is it doesn't fire on this statement although the Oracle 9i documentation states that we should
"Specify RENAME to fire the trigger whenever a RENAME statement changes the name of a database object".
What's the problem?
Thx!

Because you're triggering on RENAME but issuing an ALTER statement. The RENAME trigger will only catch statements like RENAME X TO Y.

How to get SSO logged user information in a database trigger

my database is 9i
my application server is 9i too
I need to track which SSO user is inserting data into a table , so how can i get the information of that user in a database trigger on that table
thanks

Hi,
The only way I could figure out how to get it was to import the com.sap.security.api.
1. From Window>Preferences>Java-->Classpath Variables, set up a variable called WEBAS_HOME pointing to:
<drive>/usr/sap/<SID>/jc00/j2ee/cluster/server0/
2. Right click on properties of your Dynpro Project->Properties->Java Build Path->Libraries and click "Add Variable."
3. Select WEBAS_HOME and click "Extend"
4. Select /bin/ext/com.sap.api.sda/com.sap.security.api.jar and click OK.
If you don't have access to a portal directory, you will have to get this jar file and copy it to your workspace to add to your build path instead of the above steps.
Then in your code:
import com.sap.security.api.IUser;
import com.sap.security.api.IUserAccount;
public void GetLogonID( )
     String LogonID;
     try {
          /*     create an user object from the current user */
          IWDClientUser wdUser = WDClientUser.getCurrentUser();
          IUser user = wdUser.getSAPUser();
          if (user != null) {
               IUserAccount acct = user.getUserAccounts()[0];
               if (acct != null) {
                    LogonID = acct.getLogonUid();
               } else
                    LogonID = "acct null";
          } else {
               LogonID = "user null";
          wdContext.currentContextElement().setDisplayName(user.getFirstName() + " " + user.getLastName());
          wdContext.currentContextElement().setLogonID(LogonID.toUpperCase());
     } catch (Exception e) {
          e.printStackTrace();
Hope this helps... I had to search several places before I found all the necessary stuff. Maybe I can get my first points!
Thanks,

How can I obtain an specific message raised by a database trigger

Dear friends,
if I have a database trigger and I want to show an error message which was raised from a database trigger to a form, I can do it by raising an application error inside database trigger, and by showing DBMS_ERROR_TEXT inside ON-ERROR trigger. This is ok for me.
But how can I do if I want to show a specific message? Let's say I have a BEFORE INSERT table trigger, and I want to verify whether data was correctly informed (for example, "user name must be entered"). If I raise an application error, I see a very big error message which includes both my personal error message and database message.
Surely I can do a SUBSTR in this message, but can't I do something easier? Let's say I put all error messages in a variable:
(Let's suppose it's a BEFORE INSERT trigger code, which is related to my table)
if :NEW.user_name is null then
p_error_message := 'User name must be entered.';
end if;
if p_error_message is not null then
raise_application_error (-20000, p_error_message);
end if;
... with this p_error_message being shown to final user, with no need to edit it via PL/SQL instructions like SUBSTR. Is this possible? If not, I'll be quite satisfied with SUBSTR because it fits my needs somehow.
Best regards,

raise_application_error will be used for raise errors on form.here i'm providing u the example
CREATE TRIGGER at AFTER UPDATE OR DELETE OR INSERT ON emp
for each row
declare
v_1 number
begin
select empno into v_1 from emp where empno=7369 ;
exception when no_data_found then
RAISE_APPLICATION_ERROR(-20001,'No data found'||sqlerrm);
END;
now when you insert data on emp table through form. if value does not found of selected empno then No data found will be shown on form

Is there an AUDIT option like AFTER SERVERERROR database trigger?

I want to log any and every error-exception in a test database for a period.
I have seen DBMS_UTILITY.FORMAT_ERROR_BACKTRACE article published on Oracle Magazine;
http://www.oracle.com/technology/oramag/oracle/05-mar/o25plsql.html
But before trying to build a custom application like this one;
http://apex.oracle.com/pls/otn/f?p=2853:4:1160653345033883::NO::P4_QA_ID:5922
1- I wanted to be sure if there is a specific WHENEVER NOT SUCCESSFUL Audit option for this need?
2- Also is there a way to capture NO_DATA_FOUND exception with AFTER SERVERERROR database trigger?
Thank you,
Best regards.

some stuff like following;
1)
-- the right one is conn hr/hr
conn hr/eychar
2)
-- the right one is grant select on employees to public;
grant select onnnn employees to public;
3)
create or replace procedure p1 as
begin
raise_Application_error(-20001, 'catch me if you can');
end;
exec p1;
again thank you for your interest Michaels.

Primary Key - Generated by database TRIGGER

Hi,
I have a form with a block that is attached to a table. So far, nothing fancy :-)
The Primary is generated with an ORACLE SEQUENCE. That is done at the TABLE level with a DATABASE trigger.
So in the form, the primary field is not populated.
Works fine. But if the user wants to UPDATE the forms content, right after they did an INITIAL commit, THEY CAN'T !!!!!!!!!!!
How can I code this in the form?
Is there a way to syncronize (populate) the primary key in the form with it's table content?
If so, how do I query the table if I don't have the primary key value ?
Thanks for ANY advise,
Marc.

Another solution is to use both a database trigger and a PRE-INSERT trigger in Forms.
The database trigger should be something like
CREATE TRIGGER INS_TABLENAME BEFORE INSERT ON TABLENAME
FOR EACH ROW WHEN (new.ID IS NULL)
BEGIN
SELECT TABLENAME_SEQ.nextval INTO :new.ID FROM DUAL;
END;
and the PRE-INSERT trigger should be something like:
SELECT TABLENAME_SEQ.nextval INTO :blockname.ID FROM DUAL;
This way one solves the problem of DML RETURNING VALUE not working in Forms with Oracle version > 8 (does it work on version 8 as it is said to be? - i have not tested it anyway) and the use of other applications (SQL*Plus, JAVA, etc) without writing any code.

awaiting for your response,
Thanks in advanceI'm sorry, but "showing some error" is NOT an actionable error message. Why do you think we can solve your error if you don't tell us what the error is?
Yes you will need to adjust your tnsnames. When a process in a database_A accesses database_B via a dblink in database_A, the database_A is acting as a client to database_B. At that point database_A is just like sqlplus or sqldeveloper, and all tns considerations are the same.

Kamalakar.G

Problem is here:
WHEN ( new.CREDIT_HOLD='Y')
Should be using a colon in front of any new or old columns in your PL/SQL and SQL, thus try this:
WHEN ( :new.CREDIT_HOLD='Y')
FYI: when using triggers (unless you specify otherwise in the trigger definition itself):
old values are referenced via :old.column and new values via :new.column

About database trigger

Suppose I have 2 tables A and B. There are about 40 table
columns for table A and 30 table column for table B. Table A
can insert, update and delete the record from table B. Table A
can insert, update about 15 table columns into table B. I
create database trigger on table A to insert, update and delete.
TAble B can update only 1 table columns into table A. Due to
these 2 tables A and B have update trigger. So it is mutating
when I try to update the record from table A and also update the
record in table B. Please if you have any suggestion, let me
know. I try to work around by creating the package with
variable field set to boolean. But, somehow it only allows to
update from B to A, not from A to B. Thanks in advance.

Hi, I've had this type of mutating table problem before ....
Here's a workaround:
1. Create temporary table to record the changes on the
database triggers (row triggers). Then on a after statement
issue the update statement.
2. Crear package variables at the package specification. Then
create procedures or functions to set this values accordingly
(in before and after trigger statement). Finally use after
statement triggers.

Database trigger causes error in Form

I have a database trigger on the per_performance_reviews table. When I try to save a performance review record from the forms I get the following error:
FRM-40403: A calling form has unapplied changes. Save not allowed.
Any suggestions???
Here is my trigger:
CREATE OR REPLACE TRIGGER APPS.XXPER_UPDATE_PERF_REVIEW
BEFORE INSERT ON HR.PER_PERFORMANCE_REVIEWS
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
DECLARE
l_hire_date DATE;
l_next_review_Date DATE;
l_event_type VARCHAR2(40);
BEGIN
select papf.START_DATE, pe.type
into l_hire_date, l_event_type
from per_all_people_f papf, per_performance_reviews ppr, per_events pe
where ppr.performance_review_id = :NEW.performance_review_id
and papf.person_id = ppr.person_id
and pe.event_id = ppr.event_id
and sysdate between papf.effective_start_date and papf.effective_end_date;
l_next_review_date := l_hire_date + (365 * 2);
IF l_event_type = 'APPRAISAL' THEN
:NEW.NEXT_PERF_REVIEW_DATE := l_next_review_date;
END IF;
END XXPER_UPDATE_PERF_REVIEW;

There is a forms forum here too.
However this error message
FRM-40403: A calling form has unapplied changes. Save not allowed.
implies that you opend your current form without posting/commiting in the previous form. This is not allowed. Your changes never even touched the database.

Passing variables to a procedure inside a database trigger

Hi, I am new to oracle Forms . I am having a table in database . For that table i had written a database trigger which will fire after insert or update . I am using a procedure inside the Trigger . I want to pass arguments to the procedure which is being called in the trigger . The variables which i want to pass to the procedure are one is a primary key and the other is a normal cloumn which are in the same table for which the trigger is written. Can anybody help me regarding this.?

> But when i m calling it with forms i m getting an error
You cannot call a database trigger from forms. A trigger is part of the table, e.g.:
create trigger my_trigger
before insert or update or delete on my_table
for each row

How to send error message to forms from Database Trigger

Hi, Please help me to send error message to forms from Database Trigger?
RgDs,
Madesh.R.M

You are correct, the On-Error trigger is a Forms trigger. However, if your Form is going to display the error generated by the database stored procedure or trigger - you might not see the database error in your Form unless you check the DBMS_ERROR_CODE in the On-Error trigger and manually display the Error Code and associated Text. I've see this happen with a co-worker. The Form she was working on was based on a table with an Before-Insert trigger. Because she was not explicitely handling the error from the Before-Insert trigger in the Forms On-Error trigger, her Form appeared to halt for no reason at all. Once she added code to the On-Error trigger in the Form to handle the DBMS_ERROR_CODE, she discovered the trigger was producing an error and was able to show the error to the user in the On-Error trigger.
I understand the desire to keep as much as possbile in the database, but with that comes some extra coding in your Forms to handle this. This extra coding could easily be placed in a Forms Library, attached to a Form and called in the On-Error trigger. Your code could look like this:
DECLARE
   /*This example assumes you have an Alert defined
      in your Form called: 'ERROR' */
   al_id    ALERT;
   al_text VARCHAR2(200); /* Max text of a Forms Alert message*/
   al_btn   NUMBER;
BEGIN
IF DBMS_ERROR_CODE != 0 THEN
   /* Error code is ORA-00000 Normal Successful completion
       So only handle non-zero errors */
   al_text := DBMS_ERROR_CODE||':'||DBMS_ERROR_TEXT;
   al_id := Find_Alert('ERROR');
   set_alert_property(al_id, alert_message_text, al_text);
   al_btn := show_alert(al_id);
END IF;
END;Your original question was "How to send error message to forms from Database Trigger?" The answer is you don't because Forms already gets the database error code and database message through the Forms DBMS_ERROR_CODE and DBMS_ERROR_TEXT functions. Look these up in the Forms help and it should clear things up for you.

How to rename database with secondary indexes.

Hi,
could somebody advise how to run correct next operation:
I have database with secondary indexes in a single file and I need to rename that db file.
As I understand I have to
1) close and delete all database handles
2) remove from db file all secondary indexes with DbEnv::dbremove
3) rename db file with DbEnv::dbrename
4) create primary db
5) create once again all secondary indexes and associate them with primary db
Appreciate in advance.

Hi,
Your question has two possible cases:
1. A single file contains main DB and its secondary indexes.
2. A file contains several secondary indexes of main DB, another file contains the main DB.
For the first case, the main database could be renamed directly, but all of the secondary databases do not continue to work. That means no new index items will be added automatically into exist secondary databases. So these secondary databases should be removed and created, you could also just run a DB->associate to re-associate it again. But in the later way, the re-associated secondary DB won't automatic index these records that are added before associating.
That means, if main db is renamed and then inserted a record 'A'. Then secondary DB is re-associated to main db. The secondary DB still does not index record 'A'. And currently there is not method to let secondary DB manually index 'A' again. So it is better to remove and create a new secondary DB with DB_CREATE flag. That will make the new secondary DB scan current items and index them.
For the second case, the result is the same, main database could be remained directly. Then all of the secondary databases should be re-created or re-associated. Still for the described reason, we prefer the first way.
And, removing old secondary databases before renaming main database is also work in above cases.
Thanks,
Victor Yang

Re: send message from the database trigger(URGENT)

Hi,
I am using forms 6.0 and oracle 8.0. My question is I am calling a stored procedure in the BEFORE UPDATE TRIGGER on database. This trigger will be fired and update another table(table B) when user update any record in the forms based on different table (table A).
I want to pass the message to the forms from the database trigger when records gets updated in the database e.g. (10 records are updated). Since I am not calling my database procedure from the forms, rather it is being called from the database trigger, How can i display message to the forms.
Thanks all your help in advance.

Thanks Parker for ur reply but that subprogram raise_application_error only works if there is an error in the store procedure. But in my case there is no error, I just need to pass a message saying that e.g. "12 rows updated". How can I pass this message from the database trigger to the forms application.
Thanks

Multiple Rows Update / Refresh Toplink Query when database trigger involved

Hi everybody!
I have two easy troubles for you; the platform is the same as the SRDemo Toplink version.
1. Multiple Rows Update: I want to update with mergeEntity method, multiple rows for an isolated table; that method receives a parameter that I try to bind with the iterator "dataProvider" but it only merges the first row, not all, any other combination returns an error.
What I want to do is to have a form (like tabular forms in Apex) that lets me update multiple rows in a single page. ¿May anyone tell me how to do it?
2. Refresh Toplink Named Query: I have a list on a page with two columns. From another page, a button does an action that fires a database trigger that updates one of the columns on the list´s page. When I go back to the list, it is not updated; however, the CacheResults´s property is set to false on the iterator.
Thanks in advance,
Alejandro T

I didn't use it (yet), but - you might take a look. You'll find a [url http://www.oracle.com/technetwork/developer-tools/apex/application-express/apex-plug-ins-182042.html]Timer plug-in on this page. It is a dynamic action which allows you to periodically fire other dynamic actions in the browser. For example use the timer to refresh a region every five minutes. You can perform any dynamic action you want using this infrastructure.So I was thinking: you might use it to run a dynamic action which would check whether something changed in that table (I suppose you'll know the way) (for example, a database trigger might set a flag in some table, timestamp or similar), and - if you find that something really changed - refresh the page.
As I said, I never used it so that's pure theory. Someone else might know better, though.
