For triggers, is it possible to do separate actions on insert , update and delete. For example, if insert is the case, do select; if update is the case, do select from another table and so on?
View 1 RepliesI am looking at an existing utility which inserts data into configuration tables. The utility is fairly basic, you simply add the UPDATE / INSERT / DELETE sql commands to a .sql file, set up a few params in a .sh script in order to tell it which Database / Schema to run against and away it goes, doing some logging, etc on the way.
Most of the time this is fine. However there is one table that causes big performance problems. This large table holds rating data and it has two large triggers on it. It also gets updated quite a bit with new rating tariffs.
The triggers check that many fields are not null or are certain values... but they also check that dates of the rates do no overlap, etc. So, in short, they do a lot of work. I can see that these are the main performance obstacle. I have no ability to alter or disable these triggers, this is a core table supplied by the vendor and as such I cannot manipulate it.
So looking at the things I can change, what am I left with?... only the way I load the data..
I can consider using SQLloader in order to handle INSERTS or using the APPEND hint in order to perform a direct path insert rather than having individual INSERT statements.
I can try to ensure that my data is sorted along the same lines as the index on the table in order to ensure that I am updating the index nodes in as streamlined way as possible. I can improve performance still more, or even circumnavigate the drag of the triggers?
I am trying to write a trigger that will do an insert/delete/update into a audit table when a change has occurred on the primary table. The change will be recorded in the audit table by a incemental sequence number and the updated data.
there will be an extra column in the audit table
how to get a simplified version of this trigger.
the primary table will look like so
Id_num varchar (20)
code Integer
desc varchar(20)
sequence_num Integer
audit table
Id_num varchar(20)
code Integer
desc varchar(20)
timestamp date
sequence_num Integer
How to get all the name of tables that a user can select, insert, update or delete?

View 32 Replies View Related have one XL sheet Doc that has 2 tabs. One has the list of keywords for deleting the records from Oracle that has the keywords in it. The second one needs the update query. Read the first column in the XL sheet and replace it with the second column value for the records that has the first column value in it.
I never worked in the combination of XL and Oracle.
Is there a way in oracle 10g to know when was a row inserted or updated using oracle data dictionaries.
I know we can track these by creatig a seperate date column.
I just want to know if there is built in table which shows these.
I'm trying to determine which procedures (in or out of packages), triggers or functions insert to or update particular tables in Oracle 10.2.0.4.I've got a far as looking at user_dependencies, and have written the following sql based on that:
CODEselect o.name, decode(o.type#, 0, 'NEXT OBJECT', 1, 'INDEX', 2, 'TABLE', 3, 'CLUSTER',
4, 'VIEW', 5, 'SYNONYM', 6, 'SEQUENCE', 7, 'PROCEDURE',
8, 'FUNCTION', 9, 'PACKAGE', 10, 'NON-EXISTENT',
11, 'PACKAGE BODY', 12, 'TRIGGER',
13, 'TYPE', 14, 'TYPE BODY', 22, 'LIBRARY',
[code]....
This isn't how I'd write the code for production, it's just research code at the moment.
This tells me most of what I need to know, but it doesn't allow me to remove those procedures etc that just select from the table I'm interested in. The vast majority of the dependencies are just selects. In a previous role I used SQL Server 2000 and I could get this information from sysdepends, filtering on the resultobj column to remove the select only dependencies - so I'll be a little surprised if Oracle doesn't have this facility.
I have my database structured to where i have my tables, constraints, and Rows populated in each table which is 4 tables in particular. for one I want to be able to List all four tables with its content and constraints all at once. What i want to with the PL/SQL is to be able to program a prompt to where the user can just enter the individual order information and the data goes to what ever appropriate column or Table it needs to go to. Now should I be mostly be using procedures, functions or triggers to make this possible.
View 9 Replies View Related I have a base table (Table A) block with multiple records displayed. I need to track audits to this underlying table in the following way:
If user updates a field in the block I want the pre-changed record's audit fields to be set and I need to create a copy of the record with the changed values. Basically any changes will result in the record being logically deleted, and a copy record created with the newly changed values.
Tried to implement in the block's pre-update trigger which will call a package to directly update Table A then Insert into Table A, then requery the block. Is there a clean and efficient way to do this?
i want to create a trigger that will update a table when there is an insert or update.i can't across this error that i don't even know what it means "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.

View 9 Replies View RelatedI have a large 10G database, with records being inserted almost constantly. In order to "UPDATE" records, I need to be able to DELETE the old record and INSERT the new record (even while records are being inserted into the table). It appears that DELETES won't work while records are being inserted (1.5 million records per day). Is there a way around this (which I'm assuming at this point is a contention issue)? The INSERT uses the NOPARALLEL hint; no hints on the DELETE.
View 7 Replies View Related I have a website I am working on a database for, and to insert new data into the table is not a problem, even to output the table isn't an issue.
But a delete query won't work and it doesn't return any errors or echo commands that I put in the steps of the logic.
i have a flat file with fixed positions.Records of this file are having like empid empname deptname typeEx:

I can not update and delete row from database
View -1 Replies View Relatedi have three tables: ot_req, ot_po_breakup, and ot_po. when a row is inserted into the ot_po table reffering to ot_req,there is a trigger which creates a seperate reocrd in ot_po_breakup with the details of ot_req ot_req.ri_sys_id as pb_ri_sys_id and ot_req.ri_qty as pb_ri_qty ,pi_sys_id as pb_pi_sys_id .upto this part is okand when i insert also the logic is okay.
i have created a trigger to update the rows in the ot_po_breakup table after insert on ot_poin order of pb_ri_sys_id and pb_pi_sys_id and try to update the values in the columns pb_ves1q, pb_ves2q, and pb_ves3q order. i am trying to take the quantities in ot_po.pi_qty and insert them into the pb_ves1q, pb_ves2q, and pb_ves3q columns of ot_po_breakup where those columns are empty (0 or null) such that the sum of those three columns for that row does not exceed the pb_ri_qty in that row.
My problem is i need to mofify my trigger to do the update and delete , that is whenever the user is updating the column ofot_po.pi_qtythe qty should in ot_po_breakup should get updated accordingly and sum of pb_ves1q,pb_Ves2q and pb_ves3q should be equal to pb_ri_qty and do the same for delete as well

I need to take a snapshot of a table before insert or update happens to that table.... in oracle 10g. I am reading the MV docs from oracle and below link..
[URL].......
how MV should be written for this and how to schedule it in dbms_jobs for auto refresh?
assuming that t1 is the table where DML operation are goin to happen so before any insert or update, snapshot has to be taken, and I am assuming that to do this it would look something like this?
create materialized view my_view refresh fast as select * from t1;
create materialized view log on my_view;
and then schedule in a dbms_jobs?
We have a requirement to archive and purge the tables dynamically based on the control table input. For that we have to design a control table to gather the necessary information and passed to generate the queries.
I have designed the table as below.But in this case I am not able to handle the parent and child relation ship.
Suppose one table needs to be archived and purged and that table is parent table and it is having 2 child tables, so first required data will be inserted into target table and delete from source parent and child tables. so before deleting from parent we have to delete data from all 2 child tables.
Suppose one table needs to be purged and that table is parent table and it is having 5 child tables, so before deleting from parent we have to delete data from all 5 child tables.
To handle this scenario how can I design my control table.
For archive and purge the query like this.
INSERT INTO towner_name.ttable_name
(SELECT * FROM sowner_name.stable_name WHERE condition_column<=(sysdate-30));
DELETE FROM sowner_name.stable_name WHERE condition_column<=(sysdate-30);
for purge the quey is like this.
DELETE FROM sowner_name.stable_name WHERE condition_column<=(sysdate-30);
This is my control table and I have 300 tables list to archive and purge.

I have 4 tables , Certain users need to (Select ,insert,delete) certain rows only based on nApplication id
All the tables have Application Id , Based on this application id user will (Select ,insert,delete)
I tried row level security DBMS_RLS.add_policy but it hangs every time when i query the data or when i try to drop the policy. Is there is any method to resolve this issue.
If only Row level security will solve this issue , give me some example
the following case is successfully done with mssql databases.
Case:
Table UserGroup
Columns id, name, handshake
When the handshake is set to 'd', this record should be deleted. I know it is bad behaviour by design.
What have I done so far:
- created an after update trigger (mutual error) Caused by trying a delete action in the update action, not possible.
- created a view in combination of instead of update trigger.
This causes also mutual error, or if ignored (PRAGMA AUTONOMOUS_TRANSACTION), an deadlock.
Code so far:
create or replace procedure Delete_UserGroup_sp(p_groupId in USER_GROUP.HMIUSERGROUPID%TYPE, p_handshake in USER_GROUP.HANDSHAKE%TYPE)
is
begin
if p_handshake = 'd' then
delete USER_GROUP WHERE HMIUSERGROUPID = p_groupId;
commit;
end if;
end;
create or replace view USERGROUP_V as select * from USER_GROUP
create or replace trigger USER_GROUP_T1
instead of update on USERGROUP_V
for each row
declare
PRAGMA AUTONOMOUS_TRANSACTION;
begin
Delete_UserGroup_sp(:new.HMIUSERGROUPID, :new.HANDSHAKE);
end;
One of the procedures that am working on is failing with ORA-0000: normal, successful completion error.
The procedure has got several update and delete statements and have logging enabled after each step. The problem with that again is, each time the log table gets updated thereby losing the history of until what point the procedure ran successfully.I have this issue only in production environment and unable to simulate it in dev environment which limits my options of troubleshooting the procedure code. I was using SQLERRM in the code.
Is there a way I can identify the bad records/ record causing this issue? Am very new to PL/SQL and do not know how to proceed with this.How do you debug this sort of issues??(where one procedure internally invokes another one which again invokes other one etc)
Can I achieve the merge (update-only) and delete in a single SQL statement?
merge into table_4
using
(select table_3.col1 col1,table_3.col2 col2,
from table_1, table_2, table_3
where
[code].....
delete from table_3 where <records identified in the 'using' clause of above merge>;
i.e.
delete from table_3
where (table_3.col1,table_3.col2)
in ( select table_3.col1,table_3.col2,
from table_1, table_2, table_3
where
join conditions.....
other conditions ....
group by table_3.col1, col1,table_3.col2
having count(*) >1 );
What I want is roughly as following :
WITH mywith as ( select table_3.col1,table_3.col2,
from table_1, table_2, table_3
where
join conditions.....
other conditions ....
group by table_3.col1, col1,table_3.col2
having count(*) >1 )
update table_4 set col3='N' where table_4.col1=mywith.col1 and table_4.col2=mywith.col2
delete from table_3 where table_3.col1=mywith.col1 and table_3.col2=mywith.col2;
I'm trying to simulate a delete operation through using an update on a trigger my tables are
CREATE TABLE EMPLOYEE (
LNAME VARCHAR(15) NOT NULL,
SSN CHAR(9) NOT NULL,
salary FLOAT,
dno INT NOT NULL,
vst DATE,
vet DATE,
PRIMARY KEY (Ssn));
[code]....
What I want to do is whenever there is an update on vet( valid end time) in employee, delete the values from the employee table and insert the old values from employee into the emp_history table along with the new value for vet. Here's my trigger
CREATE TRIGGER trig4
AFTER UPDATE OF VET ON EMPLOYEE
FOR EACH ROW
BEGIN
INSERT INTO EMP_HIST VALUES( : old.LNAME, : old.SSN, : old.salary, : old.dno, : old.vst, :new.vet);
DELETE FROM EMPLOYEE WHERE(SSN = :NEW.ssn AND vet IS NOT NULL);
END trig4;
//ignore the space between : and o as it makes a smily
The problem is I get an error for a mutating change, what I'd like to know is if the above trigger is possible, and if so how to implement it without giving me an error. I mean it makes sense syntactically and logically(at least to me).
Was going through this and found that
“AUDIT DELETE ANY TABLE BY <username> BY ACCESS” or “AUDIT UPDATE ANY TABLE<username> BY ACCESS”
enable audit for delete and updates for given username/schema. I want to enable auditing on delete and update on my entire database.
Why? And have we tested it in our any of existing setup? I am thinking of “Trigger after delete” but again this logic gets struck at individual tables. It do not work simply once and all for complete database/all users/all schemas
we received a design advise to add columns to track the update and delete done on each row in our tables:
- DELETED_DATE_TIME
- DELETED_BY
- UPDATE_DATE_TIME
- UPDATED_BY
In our architecture, the application can only access functions/procedures to access/modify data. Each function logs the action, the executed sql statement, oracle error, user terminal, and the user into a unified log table by using v$ tables to create a general log function that is called after execution or error.
The only advantage is that it will be easier to know the delete and last update information faster versus space and design modification.
I have created a simple page with a tabular form built on a view. The view is on top of a collection that is created when the page is ran. I added a tabular form column validation. I then was going to add a pl/sql process to handle the updates into the db, but before I did that I wanted to delete the ApplyMRU that was created when I first created the tabular form because it does not make sense on my view. When I went to delete the MRU it gave me an error saying "Multi Row Update processes can't be deleted as long as there are validations defined for the tabular form".
I have searched for an answer on this, but so far I have not found much. I am hoping it is something simple that I am missing. I even tried deleting the MRU first and then add the validation, but then it gave me another error about "Tabular form validations require multi-row update processes" I know this was possible in 4.1, but now I am trying it on 4.2
