BEFORE UPDATE TRIGGER

Hi, I just start to learn oracle and I have a problem that causes trigger to duplicate registration of the Pavilion.

CREATE OR REPLACE TRIGGER Data.DOUBLE BEFORE UPDATE ON Data.PERSONAL FOR EACH LINE

DECLARE

INTEGER TEMP;

BEGIN

TEMP: = 0;

SELECT COUNT (*)

IN TEMP

STAFF

WHERE (TRIM (NAME) = TRIM(:NEW.NAME) AND TRIM (MOTHER) = TRIM(:NEW.) THE MOTHER) AND TRIM (FATHER) = TRIM(:NEW.) THE FATHER)) OR

(BORN_DATE =: NEW.) BORN_DATE AND TRIM (NAME) = TRIM(:NEW.NAME) AND TRIM (MOTHER) = TRIM(:NEW.) THE MOTHER)) OR

(BORN_DATE =: NEW.) BORN_DATE AND TRIM (NAME) = TRIM(:NEW.NAME) AND TRIM (FATHER) = TRIM(:NEW.) «"' FATHER));»»»

IF TEMP > 0 THEN

: NEW. STATUS: = '4';

END IF;

END;

Can anyone solve my problem?

Best regards

Abdul

Thanks for all answers, now I can't believed that should never use trigger before update on the same table

Before Update trigger compilation problem

Hello experts! I have a problem compiling of a trigger, that I am creating.

In fact it should be updated INT_INITIAL with the old value of INT_LOCK.

Compilation fails and the debugger triggers an error ORA 01747 (invalid statement for table use, column user etc.)

Do you have an idea of what's wrong with my code?

create or replace
TRIGGER TRIGGER_INT_INITIAL
BEFORE UPDATE ON  TBL_MATRIX_INTERMEDIATE_RESULT
FOR EACH ROW 

 Begin 
 
  IF NVL(:new.INT_INITIAL, 0) != :old.INT_LOCK THEN 
       UPDATE TBL_MATRIX_INTERMEDIATE_RESULT set 
      :NEW.INT_INITIAL = :old.INT_LOCK;
  END IF;
 END;

Kind regards

SEB

Hi Seb,

You should not be doing an UPDATE, just do an assignment:

create or replace TRIGGER TRIGGER_INT_INITIAL
BEFORE UPDATE ON  TBL_MATRIX_INTERMEDIATE_RESULT
FOR EACH ROW
 Begin
  IF NVL(:new.INT_INITIAL, 0) != :old.INT_LOCK THEN
      :NEW.INT_INITIAL := :old.INT_LOCK;
  END IF;
 END;

help find out what is wrong w / my before update trigger
Let me this prefix w / the fact that I am a fool, so be nice.

I have a trigger that does not (apparently), and I'll google out so I thought I would ask and see if someone could not provide thoughts, insults, suggestions or what have you.

Database used is 10g XE and updates are performed in a transactional way.

I have a table that contains (among other things) the status of a particular type of transaction (specific application). When this status changes to a particular value, I have a trigger that updates another table with the date on which that status change took place.

< pre > Table: XTransaction
ID (pk)
StatusID (integer)
... < / pre >

and here is my trigger:

< pre > create or replace trigger x_transaction_update before update on xtransaction
for each line
declare
Start
If (: old.statusid = 1) then - it's here because I got an error when I tried to use a when clause above
Start
-I log in before the update with some other info to tell whether or not I've been to this task
Update sometable set when_it_happened = sysdate where xtransid =: old.id;
-I log in after the update too
exception
while others then
-I connect sqlerrm
end;
end;
end if;
end; < / pre >

Here's what I could gather through tests and display the logs of the trigger:

1. There is no exception being connected,
2. the update of pre/post connects with all the correct data (to prove that the trigger is activated),
3. when I update xtransaction for visual studio (via the oracle complement that allows to execute queries against the database), the State is changed, the trigger is activated and the other table is updated.
4. when running the application that normally updates the xtransaction table, xtransaction is updated, the trigger is activated and sometable is not updated.

So I have absolutely no idea where to go with this one. Usually I could launch sql server Query Analyzer and watch what comes through, and I tried commercial tool use Toad to do this, but nothing is. I tried to change to an update after, but had the same results. I wrote this a few months ago and it worked then, but not now.
Thanks a lot for the display of the actual error.

Are you trying to work around the famous error table mutation here?
http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:8323596621929

You should use the transaction autonomous only for error logging procedure.
You use a registration for different purposes.
You are being "independent" on totally different levels.
Creating a "while OTHERS" - registration procedure (being an autonomous transaction), or remove WHEN E.A.
(or: delete the other calls to your logging procedure).
This is a right step: get rid of the "distractions" and keep your code clean/crisp and clear as possible.

Table is the mutation of error in after the update trigger
Hello

In all of my table, I have columns EDITDATE and EDITUSER. So whenever a table is updated I need to update these two fields with the USER and SYSDATE. For this I use a BEFORE UPDATE trigger. This trigger is activated, but I get "ORA-04091: table %s.%s is changing, function of triggering/can not see" error every time I update the table. I used this method in SQL Server. I understand that Oracle doesn't have to be the same as SQL Server but I do not know there is a way to do this. Do you know what it is?

EDIT: Here is the Code of the trigger

create or replace
TR_LEGISLATION_CALCUL_AE RELAXATION
BEFORE THE UPDATE
ON LEGISLATION_CALCUL
FOR EACH LINE
DECLARE
v_LEGISLATIONCALCULID NUMBER (10,0);

BEGIN
SELECT: NEW. LEGISLATIONCALCULID

IN v_LEGISLATIONCALCULID
FROM DUAL;
UPDATE LEGISLATION_CALCUL
SET EDITUSER_ID = UID,
EDITDATE = SYSDATE
WHERE LEGISLATIONCALCULID = v_LEGISLATIONCALCULID;
END;

just put this in your before update (and not after the update as you mentioned) for each trigger line:
```
BEGIN

:new.EDITUSER_ID := UID;
:new.EDITDATE := SYSDATE;

BEFORE the UPDATE trigger between field in both tables

Hi Oracle Experts,
I'm a newbie in the triggers. I want to do a trigger that fires whenever changes are made to a table, updates a field in the second table. The details are as below:
```
 SAMPLE (
SAMPLEID    NUMBER(10,0)
ACTIVITYID     NUMBER(10,0)
ACTIVITYTABLEID     VARCHAR2(20 BYTE)
SAMPLEDT     DATE
SAMPLEPTID     VARCHAR2(20 BYTE)
SAMPLENOTIFY     VARCHAR(1 BYTE)
)
```
```
SAMPLE_RESULT(
SAMPLEID     NUMBER(10,0)
TESTID     VARCHAR2(20 BYTE)
PROPERTYID     VARCHAR2(20 BYTE)
TESTERID     VARCHAR2(20 BYTE)
ENTRYDT     DATE
RESULTNUM     NUMBER(18,8)
RESULT     VARCHAR2(20 BYTE)
RESULTTYPE     VARCHAR(1 BYTE)
RESULTSTATUS     VARCHAR2(1 BYTE)
)
```
The idea of relaxation:
```
CREATE OR REPLACE
TRIGGER "DBA".AUTO_NOTIFY
BEFORE UPDATE OF RESULT ON SAMPLE_RESULT
FOR EACH ROW
WHEN (NEW.PROPERTYID = 'Action Taken')
BEGIN

//my idea
:new.sample.samplenotify = 'S'

//but i don't know how to make a reference to another table

END;
```
The trigger will fire every time the propertyid is pronounced, it sets the value of samplenotify in the example in table for the of '.
Is this possible?
Thank you in advance.

La: new.column_name syntax applies only to the table that the trigger is on. You will need to use an update on the other table.

CREATE OR REPLACE TRIGGER auto_notify

BEFORE the UPDATE result WE sample_result

FOR EACH LINE

WHEN (NEW. PROPERTYID = "Taken Action")

BEGIN

Example of UPDATE

SET s = samplenotify"

WHERE sampleid =: NEW.sampleid;

END auto_notify;

Hi all

I need help on this trigger,

It's the scripts of the tables.
CREATE TABLE TEST (ID NUMBER NULL, NAME VARCHAR2 (20 BYTES) NULL, TYPE NULL VARCHAR2 (20 BYTES), CONSTRAINT TEST_PK PRIMARY KEY (ID));
Insert in the TEST
(ID, NAME, TYPE)
Values
(1, "caroline", "student");
COMMIT;

CREATE THE TEMP TABLE (NULL NUMBER ID, NAME VARCHAR2 (20 BYTES) NULL, NULL OF TYPE VARCHAR2 (20 BYTES), TST_ID NUMBER NULL, CONSTRAINT TEST_PKD PRIMARY KEY (ID), KEY FOREIGN (TST_ID) (ID) REFERENCES TEST);

create sequences tst_id

There are two tables.
Test table (first picture). This is a table with the original data. Now, it's so that when there is an update on this table, the record that is updated should be written to the temp(second table) table in the initial state.

For example.
the record in the table test is updated
ID NAME TYPE TST_ID
1 ColArt student 1

Temp table is inserted recording that had updates,

ID NAME TYPE TST_ID
1 student caroline 1

SO to do what I, ve written the following trigger

CREATE OR REPLACE TRIGGER CAROLINE.bru_test
BEFORE THE UPDATE
WE'RE CAROLINA. TEST
REFERENCING NEW AS new OLD IN the old
FOR EACH LINE
DECLARE

BEGIN
insert into temp (tst_id, name, id, type)
(select tmp_seq.nextval, id, name, type of test);

END;
/

But when I update the test table, I get an error of mutation.

If anyone can help with this trigger,

Thank you
something like that
```
CREATE OR REPLACE TRIGGER bru_test
BEFORE UPDATE
ON TEST
FOR EACH ROW
DECLARE
BEGIN
insert into temp(id,tst_id,name,type) values
(tst_id.nextval, :old.id, :old.name, :old.type);
END ;

```
you want to store the original values, right?
you did a SELECT INSERT - instead of INSERT VALUES

Padding with spaces before update does not

Hi, I have to insert/update to update a column in ERP which is CHAR NOT NULL.
In this ERP, if the field is null, it must be filled with spaces
Example:
my_field tank (100) not null;
Thus,.
When I update this empty data field, it must be:
```
update my_table set my_field = rpad(' ', 100)
```
It is a requirement of the ERP. I Don t have control over that.
I have a form that manage a table of this ERP. In the before INSERT trigger and the datablock UPDATE before I added:
```
:my_block.my_field := rpad(nvl(ltrim(:my_block.my_field), ' '), 100);
```
But I always got the error:
```
ORA-01407: cannot update ("BAAN"."TTBMTB108100"."T$NOCO$O") to NULL
```
Looks like it's cut the value.
Work around this problem, I creates a trigger 'before insert or update"where I replace null with space value... but I wonder if he is optioned property or that this either in the forms for it to work as (I think) should be.
Are there?

Forms will prune your article, is how forms work. TANK is really something you normally avoid and use VARCHAR2. I understand that you have no control over this.

So, your table trigger is a solution, or create a trigger to INSERT IT in your form:

declare

l_item char (10);

Start

l_item: = rpad (nvl (ltrim(:my_block.my_field), ' '), 100);
insert into my_table (l_item) values;

end;

Update trigger that inserts the record in another table
I searched the forum and the web for an example like this and I can not find a:

A field is updated in the TABLE_A and it triggers a single record TABLE_B insert that has the old and the new value of the field.

I write a lot of complex data warehouse SQL-based reports, but very rarely do much PL/SQL, any help would be appreciated.
Thanks in advance.
Hello

You can specify that the trigger should fire only when certain columns are referenced, like this:
```
create or replace trigger test_fund_trig
before update OF FUNDING
on table_a
...
```
If you do this, the trigger will not draw on statements such as:
```
UPDATE  table_a
SET     mod_date = SYSDATE;
```
You should always use an IF statement, as I mentioned earlier, if you do not want to follow the updates where the value of this column has not really changed.

Turn off FileVault before update for Sierra?

Hey, I wonder if I should turn off FileVault before update for Sierra? I was wondering if there is a response to this expertise?

I'm not an expert, but I upgraded to Sierra without turning off FileVault. I also did the same thing when the upgrade to El Capitan and Yosemite. Had no problem with any of these updates.

You do backup before updating to iOS 9.2.1?

I backed up to iCloud before update to iOS 9.2.1 just in case. I have never had problem with updates! I save on iCloud just to ensure the security of my information!

Hi there momooftwoapples,

Back up before update you your iOS or Mac OS is always a good idea. In fact, Apple recommends to do specifically in this article, which is to update the iOS:

Update the software on your iPhone, iPad or iPod touch iOS

Before you start

Make a backup of your device using iCloud or iTunes.

Thank you for using communities of Apple Support.
