my question is ,
i have three trigger one at form level,second on database level and third is on library level.
three are same .
which one will fire first,
give me answer.
Changed title to something meaningfull. Next time think about your title for a second rather than just putting oracle.
Which step in the following plan is the first step of execution
I reckon it is "TABLE ACCESS BY INDEX ROWID| BANK_BATCH_STATE"
Is that correct?
In the "Predicate Information (identified by operation id):"
section the predicates - access and filter for the step "TABLE ACCESS FULL | PYMNT_DUES" are displayed first
Isn't there any relation between the order of execution steps and the order in which predicates are displayed?

I just wanted to know how the query will be executed in case of where clause and ROWNUM clause. e.g, consider below query.
SELECT * FROM emp
WHERE dept IN (20, 30, 21)
AND salary < 10000
AND rownum <2;
My question is that when rownum will be executed?
1. First all the data according to where clause will be fetched and rownum is assigned and then rownum will be executed on that data.
2. First complete data will be fetched, ROWNUM will be applied and then WHERE clause will be executed along with ROWNUM clause.
If I have Before header Application level process (with id=5) and page Before header process (with id=5), which one will execute first? Is there any relation based on id or there is other logic? I want to understand general order of execution in the same area without manual experimenting and debugging data in both process?
Question is related for Application Express 4.2.1.00.08.
Performance issues with the below mentioned sql.After gone through execution plan we have found out the reason but we couldn't able to change the execution plan the way we want.
If we could able to join
HRMGR.HR_EXPANDED_BOOK table with MISBOMGR.ibm_client_mgr7_empid, MISBOMGR.ibm_client_mgr6_empid at earlier stage means before HRMGR.HR_EMP_STATUS_LOOKUP then my issue will be solved but somehow optimizer is not considering that path. Even i have added push_subq hint which will push sub queries to execute at earlier stage but no use. Why push_subq hint is not working in this scenario and what can be the other alternative to change the driving path.
Query :-
select /*+ push_subq */CEMP.EMP_ID,
CEMP.EMP_STATUS_CD,
EMP_STATUS_DESC,
MGR_6_EMP_ID,
MGR_7_EMP_ID
FROM

I have a trigger that is called from an update on the table, this trigger performs the procedure and this procedure update the Same record in the table That shot the trigger. this situation returns error ORA-0060 - DEADLOCK DETECTED WHILE WAITING FOR RESOURCE. Is there any way that this works?
View 1 Replies View RelatedI created one Update or Insert trigger on a table.When I executing the update statement it is giving error
Ora-04091 : Table gtest is mutating, trigger/function may not see it.
ORA-04088: error during execution of trigger test_email_change
ORA-04091: "table %s.%s is mutating, trigger/function may not see it"
Cause: A trigger (or a user defined plsql function that is referenced in this statement) attempted to look at (or modify) a table that was in the middle of being modified by the statement which fired it.
Action: Rewrite the trigger (or function) so it does not read that table.
I create this trigger:
CREATE OR REPLACE TRIGGER T_HST AFTER INSERT
On HST
FOR EACH ROW
DECLARE
Begin
INSERT INTO HST (EMP_NO, START_DATE )
SELECT EMP_NO, SYSDATE
FROM HST
WHERE EMP_NO = :NEW.EMP_NO;
End T_HRS_SAL_PERIOD_HSTY_UPD_PRI;

when I insert a new record in table HST I get this error:
ORA-04091: table HST is mutating, trigger/function may not see it
ORA-06512: at "T_HST", line 3
ORA-04088: error during execution of trigger 'T_HST'
What I wrong in this trigger?How can I modify it?

I have one problem in trigger execution. I have a small plsql block in trigger and, I want to execute it as a dynamic way. but it is giving the error. Please find the trigger code. Here my intension is that, the column name used in trigger should be dynamic. In future, if I want to switch the column name, I have to do without modification in trigger.
The error im getting is "ORA-01008: not all variables bound".

i have an understanding about Integrity constraint checking and the trigger execution sequence, which i decsribe below.
Integrity constraint are restiction on DML operation performed by the user. When a user deletes or updates or inserts a rows in a table then oracle performs certain checking to see that the data which is effecting the row abide certain rules. There are certain per-defined set or rules that can be applied on a table such as PRIMARY KEY, FORIEGN KEY, UNIQUE, CHECK, NOT NULL etc, user-defined rules can be applied on tables by using Triggers.
In both the cases the Integrity Constraint Checking is deferred until the complete execution of the statement. All rows are inserted first, then all rows are checked for constraint violations.
So when i see the trigger execution model the following steps are performed by oracle, Oracle uses the following execution model to maintain the proper firing sequence of multiple triggers and constraint checking..This is what the Oracle Documentation Library says [extract from Oracle Database Concepts 10g Release 1 (10.1)].
1. Run all BEFORE statement triggers that apply to the statement.
2. Loop for each row affected by the SQL statement.
a.Run all BEFORE row triggers that apply to the statement.
b.Lock and change row, and perform integrity constraint checking. (The lock is not released until the transaction is committed.)
c.Run all AFTER row triggers that apply to the statement.
3.Complete deferred integrity constraint checking.
4.Run all AFTER statement triggers that apply to the statement.
As for step 3 here the checking of the constraints for the statement is performed which where defered till the complete execution of the statement, then what is done in step 2b? what constraints are checked there?
my simplified database schema is:
Order
OrderID
Status
OrderItems
OrderID
EAN
Amount
Store
EAN
Amount
now,I need trigger that will on updating table Order and changing status to "GoodsReceived" increase amounts in Store according to values in OrderItems.
create or replace trigger order_received_trigger
before update
on Order
for each row
begin
if (:old.status=4 and :new.status=1) then
/*
select ean, sum(amount)
from OrderItems
where OrderID=:old.OrderID
group by ean;
*/
end if;
end;
but now i dont know how to apply that select on table Store.
How can "call one trigger of item in trigger of form"
View 5 Replies View RelatedI have an understanding that the code written in Forms 6i will be executed by the oracle forms 6i run time on the client machine whether it be a sql/plsql .
e.g. i am using the following query in the procedure( of forms 6i interface ).
insert into emp_remote
select ename from emp@db1;
so where the above query would be executed , on client machine or server named db1.
I have a set of code being perform in the package body of a program unit I want to debug step by step and see what values are being stored during executing or running the form
/* Without HP and deposit, Down Payment(GST) = Total(GST) */
if nvl(v_deposit, 0) = 0 and nvl(v_loan_amt, 0) = 0 then
v_gst_fr_dps := 0;
v_gst_hp := 0;
v_gst_bal_pay := v_total_gst;
[code].........
Like in the above example I want to see the value in v_gst_fr_dps,v_gst_hp,v_gst_bal_pay etc when executing and display in the screen.
I have below tables,
describe rpthead
Name Null Type
--------------------------- -------- -------------
RPTNO NOT NULL NUMBER
RPTDATE NOT NULL DATE
RPTD_BY NOT NULL VARCHAR2(25)
PRODUCT_ID NOT NULL NUMBER
describe rptbody
Name Null Type
------------- -------- -------------
RPTNO NOT NULL NUMBER
LINENO NOT NULL NUMBER
COMMENTS VARCHAR2(240)
UPD_DATE DATE
The fact is that we store some header in RPTHEAD and store real data in RPTBODY, the question is that if I use below SQL to query all data for a 'PRODUCT_ID'.
SELECT t0.LINENO, t0.COMMENTS, t0.RPTNO, t0.UPD_DATE
FROM RPTBODY t0 , RPTHEAD rpthead
WHERE
(
t0.RPTNO = rpthead.RPTNO
AND
t0.UPD_DATE>=to_date('1970/01/01 00:00:00','YYYY/MM/DD hh24:mi:ss')
AND
rpthead.PRODUCT_ID IN ('4647')
)
I do not want to have 'ORDER by' clause since data set is too large, the sorting takes long time, is there any way to get the result rows in the order sorted by RPTNO? We have the index for RPTNO on RPTBODY.
Yesterday i got wait event when executed simple select from table.This select was like:
SELECT emp_number from employer where subs_id = 111
I got one row, select is very fast.In our Core Bank System we have package with function which returns such information. I tested this select on test DB, and nothing wrong. But when I executed such select and package on Production DB, DB Admin saw that 88 sessions waits when my session release the resource. But what can happen, it was simple select? I used PL/SQL developer to get information from table:
1) SELECT emp_number from employer where subs_id = 111 then
2) Package with this function
Another users used Oracle Forms screen to execute package. How simple select statement could stop all DB?

I have migrated from Oracle 8i (8.1.7) to Oracle 10g, but when I execute a query in 8i without any order by clause, I get a result in ascending order. The same query when executed in 10g gives a result which is not ordered. How to get an order result in 10g. There are many forms and reports which use lov which are not ordered. Can I set the ordering at the database, so that I do not have to alter all the forms and reports.
I have also migrated my forms from 5 to 6, but the combo box in some forms in 6i do not appear at run time. How I can solve this problem. I have attached an forms5 .fmb file/.
I have two block....both are the control block.. in first block i select the date and in second block the data of that date is populated.but the data is populated using cursor in when-button-pressed trigger of that first block button.in cursor the data is selected and placed in field of detail block using into clause.... each field and one item of detail block is srno which is create in post-query of detail block using :sysyem.trigger_record.
Now i want after populated the detail block the data is sorted desc one of the field of the detail block..Can this possible using set_block_property() of block although the block is control block if yes where i should do this?
I have a real problem with form, specifically one of its data blocks. In the order by property of the block i specify it to sort on a branch in ascending order(i tried descending as well) but for some reason the form ignores that and sorts it on the ROWNUM. I even removed the where clause, the order by clause and changed the query data source type to FROM clause and changed the data source name to pre-query. I then created the query string in the block's pre-query trigger and set query_data_source_name property to that query string and still the data in the block is not being sorted on the branch number but instead on the ROWNUM.
