Create / Update Query To Use As Trigger For Updating Info In DB Dependent Upon Time
Dec 7, 2010
I am trying to create and update query to use as a trigger for updating information in a database which is dependent upon time.
I have a severity level which needs to be decreased in value after a set amount of time. the time of the action is recorded automatically on the creation of the the record. after an hour anything at severity level 2 needs to go up to 1, after 2 hours level 3 goes up to 2 and 3 hours level 4 goes up to 3
so far this is what I have
UPDATE calllog
SET timedate = current_timestamp, severityid = severityid - 1
WHERE ((severityid = 2 and timedate >= current_timestamp + (1/24)) or
(severityid = 3 and timedate >= current_timestamp + (2/24)) or
(severityid = 4 and timedate >= current_timestamp + (3/24)))
I am not getting any errors back from this sql but it is not updating the relevent information. I am using one cell for time and date in format = DD-MON-YYYY HH24:MM:SS.

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.
CREATE OR REPLACE TRIGGER set_date_end
BEFORE INSERT OR UPDATE OF issued ON shares_amount
FOR EACH ROW
DECLARE
BEGIN
INSERT INTO shares_amount(date_end) VALUES(SYSDATE);
END set_date_end;

if(condtion)
L_change_type='value'

i have two table:
QUOTE create table test1(
num number(4),
name varchar2(50));
create table test2(
num1 number(4),
name1 varchar2(50));
then i want to create a trigger before update on table test1 that i want to insert in table test2 the old values in table test1:
for example
QUOTE insert into test1(1,'cocol');
QUOTE update test1
set name='oracle' where num=1;
so i want the trigger to insert 1 and cocol into the table test2.

i am trying to create a update trigger that allows any quantity reduction of 5 units and if the reduction is more than 5 units it blocks it and just reduces it by 5.here are two scenarios
SQL Update statement where the new Quantity value being smaller than 5 is allowed by the trigger.
-- old qty 20
update purchase_order
set quantity = 18
where po_no = 'PO11';
-- new qty 18
SQL Update statement where the new Quantity value being larger than 5 is only reduced by 5 by the trigger.
--old qty 25
update purchase_order
set quantity = 19
where po_no = 'PO15';
-- new qty 20
i just have the basic trigger code, but i think it is the math that i am not getting (i was never good at math)
create or replace trigger purchase_quantity_updt
before update of quantity on purchase_order
for each row
when (new.quantity < old.quantity )
begin
-- not sure what to put here
end;

In the below Table Structure, TB_Vehicles is the Master table and TB_Cars, TB_Bikes, TB_Cars are Satellite tables which hold more info about respective vehicles.
I want users to search using the Name. So, when users enter Name as 'Access', my query should give all information about that vehicle, including that from Satellite Tables (using both TB_Vehicles and TB_Scooters).
SELECT *
FROM TB_Vehicles
WHERE V_NAME = 'Access';
Similarly, if user enters 'Linea', it should give info from TB_Vehicles and TB_Cars tables.
So, with V_NAME as input, I'll find V_TYPE from TB_Vehicles table, and using that, I need to identify which satellite table, I need to join to retrieve more info.
Do I need to use CASE or DECODE to achieve this?

At my Workplace we have a large Orcle 11g Database with 30 different tables for production control issues.I try to get a couple of different information from the database, so i started with SQL Query's, but for this problem i was not able to write an working query.
In this case i have 2 tables:
Table 1:
ID ;ORDER_NR ;DESCRIPTION ;CREATE_DATE
1 ;A500236 ;CLEAN HOUSE ;02/20/2012
2 ;A623555 ;REPAIR CAR ;01/10/2012
3 ;A866944 ;MAINTAIN EQUIPMENT ;02/11/2012
Table 2:
ID;ORDER_NR;WO_STEP;STEP_DATE;EMPLOYEE
1;A500236 ;A;02/21/2012;W0010
2;A500239 ;F;02/21/2012;W0010
3;A500239 ;S;02/22/2012;W0027
[code]....
And the result of my Query should look like this:
ORDER_NR;DESCRIPTION ;CREATE_DATE;A_STAT_AGE;R_STAT_AGE;U_STAT_AGE
A500236;CLEAN HOUSE ;02/20/2012 ;5 ;3 ;1
A623555;REPAIR CAR ;01/10/2012 ;42 ;39 ;38
A866944;MAINTAIN EQUIPMENT ;02/11/2012 ;15 ;4 ;3
The age of my query result should be calculated from the Create date of the Order.I want to know 2 things, one is how old was the Order when they reached that status A, R and U.The second this ist, how long did the order remain on the stat A,R and U (and if possible all other status also)It could happend that not each order reaches each status, so it ca go directly from A to you in this case i want display a wildcard in this row/column

Oracle 11.2 - The goal is to create a trigger on table and anytime an update, delete or insert is done on the table, write values to a second table. I have the trigger and it works except it is not loading my col1/PK values. I understand I need to do a new/old value. Col1 is my PK on Table that I want to load anytime there is an update/delete/insert on the table. How do I code the old/new variable?
My
CREATE OR REPLACE TRIGGER TRIGGER_NAME
AFTER INSERT OR UPDATE OR DELETE
ON TABLE_NAME
FOR EACH ROW
DECLARE
v_col1 TABLE_NAME.COLUMN%TYPE;

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 have a table EMPLOYEE with columns employee_id and status. I have a requirement that when an employee status is getting changed, then even its linked employee's status also should be changed to the same status value. For this, I need to handle the updating of linked employee's status using a trigger.
Since we get mutating trigger issue when try to update the originating table, I am trying to go with the approach of "in place of a single AFTER row trigger that updates the original table, resulting in a mutating table error, you may be able to use two triggers. The first is an AFTER row trigger that updates a temporary table, and the second an AFTER statement trigger that updates the original table with the values from the temporary table".
But however I am still facing the same issue.
Test case:
CREATE TABLE EMPLOYEE
(
EMPLOYEE_ID VARCHAR2(1),
STATUS NUMBER(9)
);
INSERT INTO EMPLOYEE VALUES ('A',1);
INSERT INTO EMPLOYEE VALUES ('B',1);
commit;
[code]....
Also, any alternate options (rather than using 2 triggers with temp table).

EBS version is 12.1.3. we need to update the e-mail address in per_all_people_f in Oracle EBS based on a trigger that will fire against a column in Oracle Internet Directory (OID). A trigger will be built against table ct_mail, column attrvalue. When a value is inserted or updated this value will use an api on the EBS database to update per_all_people_f.
Q => Is ct_mail the correct table to use in OID for email addresses? or can you confirm a different table?
Q => If Ok to use ct_mail as the table can you see any problems with using a trigger in OID?
Q => Finally is a database link between OID and EBS database the best way for the trigger to work?

I have a multi record block based on a view. All records in the view are displayed in the block by use of Post-Query trigger when entering the form.
The block has 5 items as follows:
1) RECORD_STATUS = a non-base table column which is a checkbox.
2) ITEM_TYPE = a text-item which has an LOV attached.
3) ITEM_TEXT = a text-item which is free format text.
4) LAST_UPDATE_DATE a date column
5) STATUS = a text item either 'Open' or 'Closed'
The LOV is based on a table of Item Types with values say, 'Type1', upto 'Type9'.
I have a Wnen-New-Record-Instance trigger which 'Posts' changes to the database. This has been included as i want to limit the values of the ITEM_TYPE column to values which have not been previously used.
Consider this scenario...
The block has 3 records.
record 1 has 'Closed' status so no updates are allowed.
record 2 has 'Open' status so updating of Item_Text is allowed.
record 3 has 'Open' status so updating of Item_Text is allowed.
I check the RECORD_STATUS checkbox on record2.
(This sets the RECORD_STATUS checkbox to a checked value and changes the STATUS column to 'Closed' by When-Checkbox-Changed trigger.) At this point the record has not been saved so if you uncheck the checkbox , then the STATUS column will go back to 'Open'. However at this point i will leave it as Checked (Closed).
I then insert a new record, only values Item4 to Item 9 are correctly shown in the LOV. I select Item4.
I then go back to the previous record and uncheck the Checkbox to say that i wish to leave it 'Open' after all (in effect no changes have occurred), then the STATUS column correctly reverts back to 'Open' by my WCC trigger. If i then SAVE the changes, the new record has been inserted on the database correctly, however the LAST_UPDATED_DATE from the record which was checked and then unchecked has also been updated incorrectly even though no net changes have actually occurred.
(because i am using WNRI trigger to limit the List of Values on the LOV column, this has incorrectly set the previous records LAST_UPDATED_DATE column to be Sysdate.)
How can i stop this from happening?

I have a non-base-table item which I want to update in the pre-update trigger of the current block.
If the content of the field exceeds 4000 characters, i get the error message
ORA-01461: can bind a LONG value only for insert into a LONG column.
The code is
update tab set long_col = :formsblock.long_col
where tab.tabpk = :formsblock.foreign_tabpk;
Workarounds would be,
1.) to delete the old dataset and insert the new one:
delete from tab
where tab.tabpk = :formsblock.tabpk;
insert into tab (tabpk, long_col) values
(:formsblock.foreign_tabpk, :formsblock.long_col);
or 2.) to change the Item from a non-database item to a database item and use the internal update of the forms-module, but both workarounds are not very satisfying.
Do you know another way to update the LONG-column within the pre-update trigger (or any other PL/SQL part of forms)?

create or replace trigger order_received_trigger
before update
on Order
for each row
begin
if (:old.status=4 and :new.status=1) then

After many tests I can't make work and update of the same table inside the same table.
Trying to avoid Mutating Table Error now I have
ORA-00036: maximum number of recursive SQL levels (50) exceeded
Sample Data :
create table test_compound (USERID VARCHAR2(10),APP VARCHAR2(15),LAST_UPDATED_ON TIMESTAMP);
insert into test_compound values ('user1','1',systimestamp);
insert into test_compound values ('user2','2',systimestamp-4);
insert into test_compound values ('user3','3',systimestamp-6);
CREATE OR REPLACE TRIGGER trigger_test
FOR UPDATE ON test_compound
COMPOUND TRIGGER
TYPE t_tab IS TABLE OF VARCHAR2(50);
l_tab t_tab := t_tab();
[code].......
When I execute :
update test_compound
set last_updated_on=systimestamp
where userid='user1' and app='1';
The trigger should update the first row and all the data from test_compound table where userid='user1'. Maybe the problem is that updating the same table inside the trigger is firing in a recursive way the trigger.

I am using Forms 6i and developed a Master Detail Oracle Form for Oracle EBS 11i application.
I was asked to write a pl/sql program so that.. When a user updating an existing record at the same time another user query the same record and try to update the same time, the record should be locked and a message should popup saying the record is being updated by another user.

I have a page which downloads statspack reports from different servers and stores them in APEX. As well as this it also display a summary of data (top 5 wait events & load profile info) when hovering an icon: [URL]... The chart will refresh itself and display the data based on the value of P10_SNAPVAL (storing the PK value). The report does not do as I expect it to do (it isn't refreshing the table). I have the following:
PL/SQL Dynamic Content region making the report Dynamic Action- Event: Change- Item: P10_SNAPVAL- Action: Refresh- Affected Element: Region - Load Profile (the PL/SQL Dynamic Content)- Event scope:
I've tried both bind & live The value of P10_SNAPVAL is changed whenever the user hovers a penguin icon (this works because the chart works).

I have two tables lets say TAB_A and TAB_B. I altered table B to include a new column from table A I wrote a merge statement as follows to merge the data
MERGE INTO TAB_AUSING TAB_BON (TAB_A.SECURITYPERSONKEY=TAB_B.SECURITYPERSONKEY)WHEN MATCHED THEN UPDATE SET TAB_A.PPYACCOUNT=TAB_B.PPYACCOUNT;
I know INSERT is for inserting new records UPDATE to my knowledge is to modify currently existing records (loosely) MERGE is one I rarely used, until this particular scenario. The code works perfectly fine, but I was wondering how could I write an update statement? Or in this scenario should I even be using an update statement?

SELECT COUNT(*)

WHERE (
:block_name.min BETWEEN minimum AND maximum

This code in my forms really works for inserting a new record. But if I will update the record itself for example, in the table 'Type 1'
Minimum Maximum
1 5
6 10
11 15
and I will update the 6 - 10 to e.g. 7, It must update but my query includes 6 - 10 data so it raise the trigger failure.
Note: The AND condition in the last part is for unique types. Because even if e.g. 'Type 2' has a Min and Max data same as the 'Type 1' the trigger will not prompt.

I have one table with one row with some coefficients. If I update a coefficient from my table I want to be updated all the rows from another table. I've made a trigger but in the second table I have a column for example TOTAL and I want that column to be multiplied with my new coefficient, and I want this for every row in the second table. How I can select that total column in the trigger for every single row and update it?
