Workflow Vs Database Trigger
Hi
I am new to workflow..i am in the learning process.. just a simple query on workflow...
What is the advantage of Workflow over the database trigger in the context of sending a mail...
i will be helpful if u send me some features of workflow...
Regards
Yram
Hi,
If all you want is to send an email, then there are better ways of doing it than to use Workflow.
Comparing Oracle Workflow to a database trigger is kind of like comparing a car and a unicycle - they do completely different things, but can do the same thing as each other if you really want to.
Oracle Workflow provides a complete workflow process management solution - a database trigger is a piece of PL/SQL which fires on an insert, update or delete operation on a table. They are completely different.
It might be worth looking in somewhere like Wikipedia to see what a workflow product can do, or the Workflow pages on OTN to see what Oracle Workflow in particular can offer.
HTH,
Matt

Start Workflow from the After startup database trigger
Hallo,
I try to startup a workflow process from a database trigger :
the after startup database trigger. But when I do this, he
doesn't startup. When I add a commit-statement after the call
to startup the workflow, my database never gets open.
What do I have to do ? And what command is used ?
Thanks a lot.

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 TI 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. -
How to Get the SSO Logged user information in database trigger

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
thanksHi,
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,

Report in PDF format and email it to some clients, using Database Trigger
Hi
Is it possible to run a report in PDF format ad email it to some clients after a specific event through Database Trigger. For example whenever a client makes an entry into order entry table (through entry form), a trigger should execute on Orders table, this trigger should execute or generate a PDF formatted report and finally mail it to Sales team?

How can I create a pdf-report in a database trigger
Hi,

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

How to specify when clause in a database trigger
I would like to create a database trigger that only fires on database create statements. In particular, it only needs to fire when tables with a specific prefix fire.
I'd like to be able to specify something in the when clause along the lines of :
CREATE OR REPLACE
TRIGGER CAPTURE_STATS
after CREATE ON rtrei.schema
WHEN ( NEW.table_name like 'RT_FOO%' )
begin
add_stats_capture( :new.min_range, :new.max_range);
end;
It looks like I should be able to use a when as part of a database trigger, but I have no idea what new would be defined to be so that I could use it... perhaps it is an object and the clause would look something like
when (new.objecttype = 'TABLE' and new.name like 'RT_FOO%')?
Any ideas? I've searched through the docs, but have not been able to find anything relevant.
thanks very much,
RobinYou can use the WHEN clause with DDL triggers. You can move Todd's IF-THEN clause up into the WHEN clause.
See http://download-west.oracle.com/docs/cd/B14117_01/appdev.101/b10795/adfns_ev.htm for all of the System-Defined Event Attributes.

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. -
Column name as a variable in a database trigger
I am trying to code a pre-insert database trigger to format all varchar2 columns entered into the triggering table. I am using a cursor to get all the relevant column names from all_tab_columns, but do not know how to refer to these values in combination with the ":new" construct within my code. The example below is a very simplified version of what I am trying to do ( it obviously will not work as it is):
declare
cursor column_cur is
select column_name cn
from all_tab_columns
where table_name = 'TEMP_ASSESSMENT'
and data_type = 'VARCHAR2';
v_columnname varchar2(30);
begin
for column_rec in column_cur loop
v_columnname := column_rec.cn;
:new.v_columnname := upper(:new.v_columnname); declare
cursor column_cur is
select column_name cn
from all_tab_columns
where table_name = 'TABLE_X'
and data_type = 'VARCHAR2';
v_columnname varchar2(30);
begin
for column_rec in column_cur loop
v_columnname := column_rec.cn;
:new.v_columnname := upper(:new.v_columnname);
end loop;
end;Seems to me like the problem in this thread:

Kamalakar.GProblem 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 -
STORED PROCEDURE & DATABASE TRIGGER
제품 : FORMS
작성날짜 : 1995-11-07
* STORED PROCEDURE
1. Oracle Forms 4.5에서는 PL/SQL Code를 Server-Side에 저장하거나 Forms 내 Trigger, Procedure로 갖을 수도 있다.
다음과 같은 경우 Procedure를 Database Server에 저장하는 방법을 선택하는
것이 좋다.
- Procedure가 Standard한 기능을 제공하여 다른 Tool이 공유할 수 있을 때.
- Procedure가 중요한 DML 기능을 가질 경우.
- Oracle Forms 4.5에서는 PL/SQL의 Version을 1.1까지 지원하므로, PL/SQL
Version 2.X 의 기능이 필요한 경우.
2. Stored Procedure의 제한사항
(1) Server가 7.0 이상이어야 한다.
(2) Pass되는 Variable은 2000 Byte이하이어야 한다.
- 2000이 넘으면 Truncate가 되고, PL/SQL에서 Value_Error Exception이
발생한다.
(3) Menu PL/SQL에서는 Stored Procedure와 Function을 부를 수 없다.
(4) Stored Subprogram의 정의가 바뀐 경우, Forms를 다시 Server와 Connect
하기 전에는 영향을 주지 않는다.
3. Oracle 7 Server 에서 제공하는 Standard Package들
- dbms_alert
- dbms_ddl
- dbms_describe
- dbms_lock
- dbms_mail
- dbms_output
- dbms_pipe
- dbms_session
- dbms_snapshot
- dbms_standard
- dbms_transaction
- dbms_utility
< Oracle7 Developers Guide 참조>
4. Calling Stored Procedures
(1) Database Procedure는 Server-Side PL/SQL Engine에 의해 실행되도록
Design된 PL/SQL Block이다.
(2) Stored Procedure를 Call하기 위해서는 EXECUTE Privilege가 필요하다.
(3) Server-Side Procedure와 Forms에서의 PL/SQL의 중요한 차이점은
Server-Side 에서는 Forms의 Bind Variable (:Block_Name.Item_Name 등)
을 인식하지 못한다는 것이다.
(4) Parameter/Return이 가능한 Data Type
- VARCHAR2 : Maximum of Varchar2(2000)
- NUMBER
- DATE
- BOOLEAN
제한사항
- TABLE%ROWTYPE, TABLE.COLUMN%ROWTYPE으로 정의된 것은 Reference가
안된다.
- Unsupported Parameter나 Return Value를 사용하면 다음의 Error가
발생한다.
* PL/SQL error 313 at line xxx, column yyy 'PROCNAME'
not declared in this scope.
* PL/SQL error 201 at line xxx, column yyy identifier 'FUNCTNAME'
must be declared.
(5) Formal Parameter의 Default Value
- Defulat Value는 제공하지 않는다.
- User가 임의로 줄 수 있다.
- Procedure Private_Test(a in VARCHAR2 := 'Hello' b in
VARCHAR2 := 'There') IS
BEGIN
Dbms_Output.Put_Line(a);
Dbms_Output.Put_Line(b);
END;
(6) 다른 User의 Stored Subprogram이나 Remote Database를 Call하려면
- User Name이나 Database Link명을 숨기기 위하여 Synonym을 생성하여야
한다.
- CREATE SYNONYM lib_hr_syn FOR libowner.lib_hr;
- Program에서 Call할 때에는 ss_num ;= lib_hr_syn.get_ssn(:EMP.EMPNO);
5. PL/SQL Compiler가 해당 Procedure를 찾는 순서
(1) Current PL/SQL Block 내에 정의되어 있는가?
(2) Standard PL/SQL Command인가?
(3) Oracle Forms 내의 Built-in Procedure 혹은 Function인가?
(4) User_Named Procedure 혹은 Function인가?
(5) Server-side에 정의된 DBMS_STANDARD Package인가?
(6) Current user가 Server-Side의 어떤 Procedure나 Function을 Access
하는가?
* 이상의 질문에 대하여 전부 'NO'라는 대답이 나오면 Compiler는 다음과 같은
Error Message를 준다.
- PL/SQL error 313 at line xxx, column yyy 'PROCNAME' not declared in
this scope.
- PL/SQL error 201 at line xxx, column yyy identifier 'FUNCTNAME'
must be declared.
* DATABASE TRIGGER
1. Database Trigger는 Forms에서의 Trigger와 개념적으로 거의 동일하다.
차이점은 Trigger가 Fire되는 원인을 제공하는 사건과 후속코드가 실행되는
장소가 틀린 것이다.
2. Database Trigger는 Table과 연관된 PL/SQL Block들이다. Table에 대한
UPDATE, INSERT, DELETE 등의 행위에 의해 Fire된다.
3. Error 발생 시에는 RAISE_APPLICATION_ERROR Built-In Procedure를 사용하
여 Error를 표시한다.
RAISE_APPLICATION_ERROR Procedure에서는 Error Number가 20000 - 20999의
Range를 가진다.
4. Creating & Editing Database Triggers
아래와 같은 적절한 권한이 주어진다면 Forms Designer Mode에서 Database
Trigger를 직접 Create, Edit, Compile, Browse 할 수 있다.
- Execute Privilege, Create Privilege, Compile Privilege,
Drop Privilege
* Create하려면
- Navigator에서 Database Objects와 Table Nodes를 Expand한다.
- 원하는 Table을 선택하고 Expand한다.
- Triggers Nodes를 선택하고 Menu Bar의 Navigator*Create를 선택한다.
- Database Trigger Editor에서 작성, compile한다.
* Edit 하려면
- Navigator에서 Database Objects와 Table Nodes를 Expand한다.
- 원하는 Table을 선택하고 Expand한다.
- 원하는 Trigger에서 Double-Click하면 Editor가 나타난다.
- Database Trigger Editor에서 변경, compile한다.not possible via forms
you can debug it on SQL Developer by using manual INSERT Updates commands
