  Is there a parent-child relationship between the tables involved in the triggering event? Is there a foreign key used above the child table that references the parent table?

  If you have a parent-child relationship and a trigger on the parent table must be running some DML on the child table, and, if the child table as a foreign key (FK) back to the parent table, any DML on the child table will cause a recursive SQL statement to check the constraint. Indirectly, this will cause an exception table mutation.

  So watch the dependencies on SOR_O_HISTORY / FS_TEST_HISTORY/all other related table. A FOREIGN KEY can make it to mutate (no pun intended).

  Hope this will help you find the root cause.

• PL/SQL TRIGGER BEFORE INSERT, DELETE OR UPDATE

  Dear
  
  
  I have 2 paintings; Catalog and Catalog_bak (read back as backup)
  
  I need a trigger that after a DML (INSERT, UPDATE, DELET), copies all information from the table in the catalog to Catalog_bak table, adding 2 additional fields: change_type, change_date.
  
  The change_type field should show a value meets the DML that fired the trigger. If the trigger is fired by a
  INSERT == > 1
  UPDATE == > 2
  DELETE is > 3
  
  So my question is: How can I determine if it was an INSERT, UPDATE, or DELETE command that triggered the trigger.
  
  
  Yours Sincerely

• Helps relaxation that fits into another table before insertion

  I have two tables:
  
  TABLE A as follows:
  x, y, z

  TABLE B as follows

  I want a trigger, BEFORE insertion in the TABLE B, I want to INSERT into TABLE A as follows:
  
  c = > x
  d = > y
  e = > z
  
  ONLY IF a (x, y, z) record does not already exist in the TABLE.
  
  That is to say. If record (1, 1, 3) already exists in the TABLE, we do not try to put it back when you insert in the TABLE B with values containing (1, 1, 3).

  You will need

  CREATE OR REPLACE trig_on_insert
  BEFORE INSERT ON B
  FOR EACH ROW
  IS
     lv_count    NUMBER := 0;
  BEGIN
     SELECT COUNT(1)
       INTO lv_count

        AND z = :new.e ;
  
     IF ( lv_count = 0 ) THEN
        INSERT INTO A VALUES(:new.c,:new.d ,:new.e);

• Redirect data to another table using before insert trigger.

  Dear all,
  How can I redirect the data to another table in a before Insert trigger? My database is Oracle10g.
  I have a table EMP (EMP_ID, LAST_NAME, SALARY).
  I have another EMP_COPY table with the same structure. I also have a before Insert trigger on the EMP table.
  Based on a condition that I have to redirect the data in table EMP_COPY. Let's say the condition is EMP_ID = 100.
  I fire an insert on EMP table for example INSERT IN EMP(EMP_ID,LAST_NAME,SALARY) VALUES(100,'Dev',500).
  On the inside of the front Insert trigger on the EMP table, I have the code
  IF EMP_ID = 100 THEN
  INSERT INTO EMP_COPY (EMP_ID, LAST_NAME, SALARY)
  VALUES(:NEW.) EMP_ID,: NEW. LAST_NAME,: NEW. SALARY);
  COMMIT;
  ON THE OTHER
  NULL;
  END IF;
  But the problem here is that data goes to EMP table of origin also although I don't want. He should do an Insert into EMP table only if EMP_ID! = 100.
  
  One way has been to raise a user-defined exception inside the If statement and not handle it so that the original insert on table EMP fails but INSERT comes in the EMP_COPY table. But in this solution since the inside the trigger unhandled exception, it propagates to the calling environment. And I can't stand outside relaxation as the calling environment is a form of Oracle Apps standard that cannot be customized.
  
  Any kind of help will be highly appreciated that I am fighting for more than two weeks.
  
  Thanks in advance

• Before Insert TRIGGER to create partitions problem

  Hello
  
  I m having a problem with the following situation in Oracle 8i:
  
  I have a table TEST_TABLE, which is divided by the beach with a DATE column. The idea is to have a partition for each month, so the HIGH_VALUE of partitions is always the first day of the month following that represents the partition.
  
  I created a BEFORE TRIGGER INSERT on the table TEST_TABLE, which tests if the partition for the month of registration which is being inserted exists and, in case it doesn´t, a PROC AUTONOMOUS_TRANSACTION is called to create the TRIGGER.
  
  Running the code below one can see that even if partitions are created as expected, when you try to insert a record with a date greater than the last partition for the first time, this error is returned:
  ORA-14400: inserted partition key exceeds plu legal partition key.
  
  Note that if you run the same statement again insert, it s inserted correctly on the partition that was created the first try.
  
  I´ll appreciate any help on this matter.

  ----------------

  It is the use of the pragma AUTONOMOUS TRANSACTION. Your current transaction cannot see the result of this DOF since it occurs outside of the current transaction. The clue is in the name.

  Of course, you cannot run the DDL in a trigger without use of this pragma, so you're pretty much stuck. There is a solution in 11g, but that will not help you. Unfortunately, your only option is to pre-create the partitions required in front of the need. For example, you might have a DBMS JOB to create a partition for the next month, which takes place the last day of each month (or logical date of company).

• Truncate a field before inserting

  Suppose I have the following text:

  Array: mytable

  field: username (VARCHAR2 (35))

  field: zip (VARCHAR2 (5))

  I am importing data from an excel with columns username and zip file. A couple of the usernames contains more than 35 characters, and some postal codes are in the format xxxx-xxxxx, therefore containing more than 5 characters.

  I tried to write an insert before truncating the data until they are inserted. For any user name that is longer than 35 characters in Excel, simply truncate the username to the first of 35 characters. Similarly, for any ZIP code which is above 5 characters, just truncate the zip on the first 5 characters.

  The trigger for postal codes:

  CREATE OR REPLACE

  Trigger_zipc RELAXATION

  BEFORE INSERTING

  ON mytable

  FOR EACH LINE

  BEGIN

  SELECT substr (: new .zip, 1, 5)

  IN: new.zip

  Double;

  END;

  However, I get the error: ORA-12899: value too large for column

  I understand that this happens because the value is read before my validation, and because the value is too large, it is not allowed to insert.

  I'm not sure where to go from here. Any suggestions?

  Is it excel file or a csv file.

  I think you can look into creating an external table as well.

  Before inserting it just to make a substring.

  Something along the lines.

  CREATE TABLE ext_data (
   username CHAR(500),
    zip CHAR(500))
    ORGANIZATION EXTERNAL (TYPE ORACLE_LOADER DEFAULT DIRECTORY ext_tab_dir
    ACCESS PARAMETERS (FIELDS TERMINATED BY ',')
    LOCATION ('csv.dat'));
  
  insert into mytable
  select substr(username,1,35) , substr(zip,1,5) from ext_data;
  

  I hope this helps.

• Trigger cannot insert because of insufficient permissions.

  Hello
  
  I have the following problem:
  I connected under a UserA, UserB to create. Also in the schema UserB I create TableB and sequence B. Then UserA schema, I create TableA and before the insert trigger on the table that inserts a new record in TableB.
  
  When I run the script, a warning is issued to relax. If I try to manually compile the trigger, I get the message: ORA-01031: insufficient privileges. So in big trigger impossible to insert a record into TableB UserB schema. However I can manually insert a new record into from TableB to a schema of UserA. Where is the trap? :( I thought UserA as 'parent' of UserB would have all the necessary privileges. But if I want to compile correctly the relaxation that I give select sequence and insert into TableB to UserA.

• Trigger for insertion post

  Hi all
  
  I want to update a column on the newly inserted row. So I wrote a trigger on the table, but it does not update the current row. For example
  
  If there were two rows of the table with the same criteria, two were created a minute ago, trigger will update the two lines but not the current.
  
  No idea how to upgrade the new line. I think that AFTER insertion, row trigger should be available in the table and must be updated, but is not.
  
  Thank you

  I created another table:

  crate table keywords(
  k_id number(14),
  keywords varchar2(500) unique
  );
  
  create sequence keywords_pk_seq
  start with 3484 increment by 1;
  
  create or replace trigger keywords_pk_trig
  before insert on keywords
  referencing new as new
  for each row
  begin
  select keywords_pk_seq.nextval into :new.k_id
  from dual;
  end;
  /

  I want to:
  one) to split columns of company.products where is comma (,) for example, bars, tubes, pre-soudures, tubes will became 4 different as words:
  bars
  tubes
  welds
  tubes
  
  (b) then I want to insert these words in the table keywords.keywords with condition separated by ignoring the existing keywords.keywords (e.g. tubes came twice, let's get just a tubes) for example
  k_id keywords
  1 bars
  2 tubes
  3 before welding
  
  Thank you and best regards

  You can use the merge statement:

  for example

  merge into keywords
  using (
  with t as (select 'pipes,taps,spanner,spade,tubes' as txt from dual)
  -- end of sample data
    select distinct REGEXP_SUBSTR (txt, '[^,]+', 1, level) kw
    from t
    connect by level <= length(regexp_replace(txt,'[^,]*'))+1
    ) x
   on (keywords.keyword = x.kw)
  when not matched then insert (id, keyword) values (key_seq.nextval, x.kw)
  /
  

  But keep in mind that the sequence in this example will be updated for each line independently to know if she gets inserted or not.
  If you set the ID using a sequence triggered when inserting then this will solve this problem.

• How to delay a PXI-5122 trigger before routed to string of PFI

  Hello world

  I use a PXI-5122 in a PXI chassis. I want to synchronize with two external devices. The first will send a trigger (with a 10 Hz repetition rate) for PXI-5122. Then PXI will generate a trigger (with a constant delay) in the second.

  It seems that I need to generate a trigger, then export this trigger to PFI 0 line, but I do not know how to delay triggers with a timeframe of 4µs. I read that there is a slight delay between a trigger on the PFI and the first sample. And the length of the cable is also an important factor to consider.

  Could someone give me some suggestions?

  Wednesday,

  Thanks for the drawings, that helps a lot!  Somehow, I see this work (how to set up the scanner):

  1. set up the record length to be 12us (4us trigger samples, 8us after outbreak).  If the sampling frequency is 100 ms/s, that would be a record length of 1200 samples.

  2 configure the position of record reference to 33%.  That's how the digitizer breaks 1200 400 samples according to trigger before triggers and 800 samples.

  3. configuration of triggering immediate reference.  This will allow the acquisition of trigger the moment she gained 400 before triggering samples.

  4. export the "reference trigger (Stop)" to send to Device_2.  This output pulse is of variable width, so if you want consistency, you will need to the Device_2 trigger the rising edge of the pulse, did not not fall m.  Once 400-pre-trigger samples are acquired, this impulse will be sent, and then the scanner will be immediately habitable after initiation of sampling.

  5 configure the trigger of the entrance of Device_1 (10 Hz trigger), as the 'Advance trigger' and 'Start Trigger'.  This will make the digitizer wait this impulse to start sampling before the next record.  We set up, the relaxation of beginning to the 1st record and the trigger in advance for all subsequent records.

  This facility should allow a pretty decent timing, but please test to be sure that it will be sufficient for your application.

  Kind regards

• Trigger to insert data on the null columns

  Hi all

  How can I create triggers to insert data into a column null, this column is a Varchar2.

  Thanks in advance.

  Something like this:

  create or replace the TRG_BI_MYTABLE before insert on MYTABLE for each line

  Start

  : new. MYCOLUMN: = nvl(:new.) MYCOLUMN, 'A value');

  end;
