I've been asked to look into ways I an execute an application with a trigger. I know I could set some database flag and have an application look at the flag and execute an application based on this, but my boss really doesn't wanna go down this route.
I was told I can use either C or java within the trigger somehow to execute an application (for example notepad.exe)
I am trying to use execute immediate in a trigger. See the below example
create table test_tbl(col1 number,col2 varchar2(10), col3 date);
create table test_tbl_log as select * from test_tbl where 1 = 2;
create or replace trigger test_trig
after insert or update or delete on test_tbl
for each row
declare
v_str varchar2(4000);
[code].......
insert into test_tbl values(3,'test',sysdate);
I got the Error : -1008->ORA-01008: not all variables bound
In the execute immediate statement if I change the v_using_str variable to :new.col1,:new.col2,:new.col3 trigger is running fine. But here I have to create trigger on all the tables in my schema and I dont want to list all the column names for each table manually and I am using a for loop to build the v_using_str string in my original code.
We have developed a code which builds a trigger on a atble dynamically at run time usinf Dynamic SQL command Execute immediate.
create or replace
PROCEDURE GENERATE_TRIGGER
(
P_TNAME IN VARCHAR2
[Code].....
I am not usre if the error is due to insufficient privileges as we are able to build tabl;e in the system dynamically using the above mentioned command.
I want to execute a db trigger once for updation of more than one record on a single primary key. The updation would be made by a 10g form by using the common tabular data block.

I have a problem in my form. In my form there are 4 blocks and in one of the block i have a button. In which i put a code same as below:
BEGIN
IF NAME_IN('SYSTEM.FORM_STATUS') = 'CHANGED'
THEN
CLEAR_FORM(NO_VALIDATE);
END IF;
PROCEDURE ABC;
END;
So as per code i want to clear all the changes in form for current session and want to call the procedure ABC after that. But it is not calling the procedure ABC. And what would i do to perform the same?
I would like to create a trigger that will execute a stored procedure when a package/function/procedure is compiled. I tried creating an update trigger on user_objects, but it statues aI cannot create that trigger tyoe on views.

View 3 Replies View RelatedI just started to play with this system and don't understand how to execute the the stored procedure (that creates report) from the APEX page. I know that they have sample documentation and java script call (show below):
<script language=”JavaScript” type=”text/javascript”>
function callMyRep() { var formVal1 = document.getElementById(’P_PAR1′).value;
var url;
url = ‘rep1?p_session_id=&SESSION.’+'&p_par1=’+ formVal1; window.location.href=”f?p=&APP_ID.:12:&SESSION.”;
w = open(url,”winRep”,”Scrollbars=1,resizable=1,width=800,height=600″); Close here. X

In this example rep1 is the stored procedure that creates report.How can I execute it using url?
I'm editing, say, list of my employees in a tabular form opened in Skillbuilders Modal Page. I have to execute same javascript code after the changes in the tabular form have been submitted.
I've tried using a Dynamic Action fired on Page Load, but that gets executed before the update is completed.
I have some Javascript in an Apex page, running in 'Execute when page loads'. It does some stuff to a results grid. It works fine on page load, but then doesn't run when I page through, or sort the grid. I presume this is because the grid is being sorted / paged using Ajax, which means the page isn't being fully loaded. Is there anywhere else I can put the code so it gets applied to the grid on sorts and paging?
View 2 Replies View RelatedI'm working with old code that uses dbms_sql.execute to build/execute dynamic sql. In our case, the user can select varying columns(I think up to 20) with different where conditions as needed.
After building the sql, here's an example
WITH ph AS
(SELECT ph.* FROM po_header ph WHERE 1 = 2),
pf AS
(SELECT DISTINCT pf.order_id, pf.fund
FROM po_fau pf, ph
WHERE 1 = 1
AND ph.order_id = pf.order_id
[code]....
Where table records for
po_header = ~567746
po_fau = ~2153570
and PK "order_id" is a NUMBER(10) not null and a snippet of the code looks like
nDDL_Cursor := dbms_sql.open_cursor;
dbms_sql.parse(nDDL_Cursor, sSQLStr, 2);
FOR x IN 1 .. nCols LOOP
sCols(x) := '';
dbms_sql.define_column(nDDL_Cursor, x, sCols(x), 100);
END LOOP;
nError := dbms_sql.execute(nDDL_cursor);
why when the "execute" statement is fired off the elapsed time takes ~4.5 seconds but If I change "1 = 1" above to "1 = 2" it takes ~.2 seconds. If I run the above query interactively it takes ~.2 seconds. Shouldn't the above query when joining
ph.order_id = pf.order_id
return zero rows back instantly or does the "dbms_sql_execute" do some other type of parsing internally that takes cpu time.
We can execute dynamic sql using both execute immediate and ref cursor..But what is the difference between the two and performance-wise which is better?
View 5 Replies View Relatedi'm designing a DB_application where a user makes certain subject selections depending on what grades they have. so far ive made simple signin form as follows....
Create table Persons(
person_id number(8) constraint pk_Persons primary key,
person_pword varchar2(16) not null;
declare
user_id number(8);
user_pword varchar(16);
alert_button number;
begin
[code]...
now the next step... that SIGNED IN user is taken to a menu with links to select their topics or units. HOWEVER only a PARTICULAR link can be followed depending on what grade they've achieved in a NECESSARY UNIT for example to do advanced maths u need beginners maths = PASS. if = fail then user cannot proceed. heres my sql as well as the trigger ive made an attempt at...
Create table Grades(
grade_code number constraint pk_Grades primary key,
grade varchar(4) check (result in ('fail','pass')),
person_id number,
unit_code number,
CONSTRAINT fk_Persons FOREIGN KEY (person_id) REFERENCES Persons (person_id),

i know my second trigger is poorly designed and lacking.
I have a Page containing 3 reports and I was wondering if it is possible to re-execute only one of the these reports using a button or preferably a Select List which allows me to choose which of the 3 reports I wish to 'refresh/re-execute'. I may be totally wrong here but I assumed that choosing the option to submit a Page will cause all regions to refresh i.e. re-execute the SQL queries they are 'based on'.

What's the correct way to format this kind of dynamic query?
I found this query in one of my stored procedures that updates a key for a value in a data table by reading the information from a master table.
The data table is: ITEM_INVENTORY
The master table is: MASTER_SOURCE_SYSTEM
UPDATE ITEM_INVENTORY I
SET I.SOURCE_SYSTEM_ID =
(SELECT NVL(M.SRC_SYS_ID,-100)
FROM MASTER_SOURCE_SYSTEM M
WHERE M.SRC_SYS_DESC(+) = I.SOURCE_SYSTEM_CODE )
WHERE ORG_CODE = 'TNXC'
AND EXISTS (SELECT 1 FROM MASTER_SOURCE_SYSTEM M
WHERE M.SRC_SYS_DESC(+) = I.SOURCE_SYSTEM_CODE )
The situation here is that:
1. There are about 15000 rows that match ORG_CODE = 'TNXC'.
2. The SOURCE_SYSTEM_CODE is same for all the 15000 rows and there is a matching entry for it in the MASTER_SOURCE_SYSTEM table.
My question is: Do both the inner select statements execute 15000 times?
The statement executes within a second and updates 15000 rows. How is this made possible?
