How to call a Procedure in Trigger Just call it by passing its parameters.
and if any exception occurs in trigger then How do we rollback it?You dont have to rollback. Trigger depends on the parent transaction. So if you just allow the raise the exception it will automatically rollback.

Problem in calling a procedure in form builder

sir
i have developed a procedure in pl\sql libriries but when i call this procedure from trigger compiler can not recognized this procedure.
procedure is: computetotal
libraries name is pl_004
plese help me and give me solution
thanks in advance

It the library is attached, expand the attached library, and try dragging the program unit in question, to local program units of the form and then try to compile the form.
The only cause could be that library is not attached to the form, so give this above method a try to cross-check.

Calling a procedure from within a trigger

Hi,
I have a table (table1) which when a row is inserted into this table I need to populate a number of tables based upon gathering information from multiple tables using three fields passed in from table 1.
I therefore proposed to create a before insert trigger on table1 calling a procedure which passes in the three new values as follows:
CREATE OR REPLACE TRIGGER trigger1
BEFORE INSERT ON table1
FOR EACH ROW
BEGIN
package1.populate_tables(:new.col1, :new.col2, :new.col3) ;
END;
This compiles fine, but when I actually insert data in table1 then I receive the following message and do not know how to get round it:
ORA-04091: table table1 is mutating, trigger/function may not see it.
I am using other fields in table1 to insert values into other tables (confusing I know).
If anyone can help me I would appreciate it, or if you require any more information I would be very happy to provide it.
Thanks in advance.

How to Call Procedure from Trigger body?

I have a procedure that works which I tested from sqlplus with 'exec proc_name;'
what I want is to call this procedure from the trigger and pass the parameters to the proc. the trigger fires AFTER INSERT of certain table and I want to pass those just added attribute values to the proc.
please help.
I have tried to do 'exec proc_name' from the trigger but it does not work?

You don't use exec within pl/sql, just proc_name followed by your parmateters. From within a trigger, the just added values will be :new.column_name. So, you would have something like:
CREATE OR REPLACE TRIGGER your_trigger_name
AFTER INSERT ON your_table_name
FOR EACH ROW
BEGIN
proc_name (:NEW.column_name1, :NEW.column_name2);
END your_trigger_name;
/You will need to have corresponding input parameters in your proc_name procedure, something like:
CREATE OR REPLACE PROCEDURE proc_name
(p_column_name1 your_table_name.column_name1%TYPE,
p_column_name2 your_table_name.column_name2%TYPE)
AS
BEGIN
-- whatever processing you want to do
END proc_name;

Call Stored Procedure inside a db trigger

Is that possible to call stored procedure inside a db trigger ?
I User this code:

       Into vn_count
       From Sale_Technical_Support
      Where Sending_Flag = 1
        And Support_Type = 2;

                               2);
    End If;
   End;
End If;
End;
/No errors but the procedure doesn't executed !!!!!

1) If you are using autonomous transactions for anything other that writing log data that you want to preserve even if the triggering transaction fails, you're probably doing something wrong. There is no reason to use an autonomous transaction here.
2) You don't want to send email from a trigger. You don't want to do anything non-transactional in a trigger. Oracle will, for example, rollback and re-execute parts of a statement for write consistency. If you send email in a trigger, you may get multiple emails for a single update. You may also get emails for updates that were never committed. And if the email server happens to be down, your transactions will fail.
3) If you use an autonomous transaction, the trigger will have a completely different transaction context from the parent. So when you query the table within the trigger, you won't be able to see any of the uncommitted changes including the changes that caused the trigger to fire. My guess is that you are assuming that the row that you inserted is visible to the trigger.

Need sample source code for calling stored procedure in Oracle

Hi.
I try to call stored procedure in oracle using JCA JDBC.
Anybody have sample source code for that ?
Regards, Arnold.

Thank you very much for a very quick reply. It worked, but I have an extended problem for which I would like to have a solution. Thank you very much in advance for your help. The problem is described below.
I have the Procedure defined as below in the SFCS1 package body
Procedure Company_Selection(O_Cursor IN OUT T_Cursor)
BEGIN
Open O_Cursor FOR
SELECT CompanyId, CompanyName
FROM Company
WHERE CompanyProvince IN ('AL','AK');
END Company_Selection;
In the Oracle Forms, I have a datablock based on the above stored procedure. When I execute the form and from the menu if I click on Execute Query the data block gets filled up with data (The datablock is configured to display 10 items as a tabular form).
At this point in time, I want to automate the process of displaying the data, hence I created a button and from there I want to call this stored procedure. So, in the button trigger I have the following statements
DECLARE
A SFCS1.T_Cursor;
BEGIN
SFCS1.Company_Selection(A);
go_Block ('Block36');
The cursor goes to the corresponding block, but does not display any data. Can you tell me how to get the data displayed. In the future versions, I'm planning to put variables in the WHERE clause.

Hi Mara,
You are right thats what i want
I have a table A
EmpNo Empname Currtuser_id Update_date Updateby
1 Denis Oracle
2 Scott Scott
3 Mara MMara
1)what i need to do is when any user tries to update the table Table A
Then the Trigger or procedure should check whether user is exits in table A in column currtuser_id
If his user id exits in table A
Then allow him to update the TABLE A
and insert his EMPNO in UPDATE_BY
and SYSDATE in UPDATE_BY
He will do all this process using forms
But i need to have trigger or procedure in database level for table
2) I have another table like 10 tables
Suppose TABLE B
When user tries to update TABLE B
Then the Trigger or procedure should check whether user is exits in table A in column currtuser_id
If his user id exits in table A
Then allow him to update the TABLE B
and insert his EMPNO in UPDATE_BY
and SYSDATE in UPDATE_BY
3) I need to have a common Procedure and call that procedure in all tables in UPDATE TRIGGER
Thanks for your help
Thanks

CALLING STORED PROCEDURE IN DATABASE FROM FORMS4.5

Is there any body know how to call stored procedure from Forms 4.5 ?
I am writing a when-button-pressed trigger.
Put the stored procedure name on there. But
it said "stored procedure name is not declared on this scope".
Thanks a lot

Try logging in to SQL*Plus and running the procedure, e.g....
SQL> begin
database_procedure_name(update_web);
end;
If it runs OK there, then it should run from within your form (provided that you are logged in as the same user as the test with SQL*Plus.

EXP
6 rows selected.
so, the same out put i need to get it in a report.
Thanks

Thanks for ur suggestions.
i have 2 select statements.1st query is the main query for the report.so i used it at the time of report created with datablock.
now my 2nd query is
select letter_content
from ( select content_seq,
     content || case content_seq
when 2 then
' ' || lead(content) over (partition by letter_id order by content_seq)
end as letter_content
from exp_letter_contents
     where letter_id = 103)
where content_seq <> 3;
i had taken 2parameters 1 for the main query and 2nd is for the above query(parameter is letter_id).
now i have to write the above select statement in the report.
so i had taken a field object in the report and then i had written this code in before report trigger.
function letter_contentFormatTrigger return boolean is
begin
select letter_content
from ( select content_seq,
                    content ||
                    case content_seq when 2 then
                         ' ' || lead(content) over (partition by letter_id order by content_seq)
                    end as letter_content
          from exp_letter_contents
          where letter_id = 103)
where content_seq <> 3;
return (letter_content);
end;
when i tried to compile it.i got an error as follows :
error 103 at line6,column 5
encountered the symbol "CASE" when expecting one of the following:
(- + mod null <an identifier>
<a double-quoted delimited-identifier><a bind variable> avg...etc

Calling stored procedure from Developer/2000 Forms 6.0

Dear friends,
I would like to know how do you call a stored procedure(actually a function) that I have made in Oracle 8i , to be called through Developer 2000 Forms 6.0. I am running Oracle 8i on Windows NT.
Kindly tell me the method.
Thanks in advance.
null

You can just call the procedure in any program unit in Forms as if it were a local program unit or built-in.
Thus if you have a function:
function CalculateSomething return number;
In Forms 6i, for example in a When-Button-Pressed trigger:
declare
n number;
begin
n := CalculateSomething;
end;
