  Thank you.

  You can try something like this given below to complete the historical table on update and delete.

  create or replace TRIGGER  "CLONE_EMP_UPDATE_DELETE"
  BEFORE DELETE OR UPDATE ON EMP
  FOR EACH ROW
  DECLARE
      PRAGMA autonomous_transaction;
  BEGIN
  INSERT INTO JOB_HISTORY("EMP_ID","EMP_NAME","DESIGNATION","TEAM_ID","TEAM_LEADER_ID","SUPERVISOR_ID","MANAGER_ID"
  ,"HIRE_DATE","RELIEVED_DATE")
    VALUES(:OLD.EMP_ID,:OLD.EMP_NAME,:OLD.DESIGNATION,:OLD.TEAM_ID,:OLD.TEAM_LEADER_ID,:OLD.SUPERVISOR_ID,
  :OLD.MANAGER_ID,:OLD.HIRE_DATE,
  :OLD.RELIEVED_DATE);
  COMMIT;
  END;
  

  Hope this helps you,

• How to design a trigger to update only if a column value is changed?

  Hello
  
  I have a nice little trigger that updates the CARD table when the table is updated. This table is updated within a master/detail form. It's the main table.
  Relaxation is used mainly to update the columns 'FICHE_MODIFIEE_PAR' (in English, it means "modified by") and "DATE_MODIFICATION" (in English, it means 'date modified'). I wish that these columns updates ONLY when the values in the columns 'TOTAL_HEURES' and 'TOTAL_HEURES_EXCEPTIONNELLES' are changed. These two columns have a default value for the number 0. That means that these columns change means change it value from the value 0 by default with another value or a value to another value. If the value of one or two of these two columns changes, the trigger must be fired for updating the column 'FICHE_MODIFIEE_PAR' and 'DATE_MODIFICATION '.
  

  create or replace TRIGGER  OBSERVATOIRE.TIB_FICHE
    before insert or update on OBSERVATOIRE.FICHE
    for each row
  begin
      if inserting and :new.fiche_id is null then
          select FICHE_SEQ.NEXTVAL INTO :new.FICHE_ID from dual;
      end if;
      if inserting then
          :new.fiche_cree_par := v('USER');
          :new.date_creation := sysdate;
      end if;
      if updating then
          :new.fiche_modifiee_par := v('USER');
          :new.date_modification := sysdate;
      end if;
  end; 

  Thank you for your help.

  Hello Christian,.

  You can reference and compare the old and new values. For example
  IF: NEW. TOTAL_HEURES <> : OLD. TOTAL_HEURES OR: NEW. TOTAL_HEURES_EXCEPTIONNELLES <> : OLD. TOTAL_HEURES_EXCEPTIONNELLES
  THEN
  do your stuff
  END IF;

• Hi, I recently bought numbers in order to create a commercial newspaper. I'm the pen and paper. I need help to create a formula. A purchase column determines if the entry price column is subtracted from the price of output column or output subtracted

  Hi, I recently bought numbers in order to create a commercial newspaper. I'm the pen and paper. I need help to create a formula. A purchase column; Determines if the entry price column is subtracted from the price of output column (buy) or subtracted from (Sell) entry exit. Thank you for your help

  Hi B',.

  Buying and selling in column B

  Price of entry in column c.

  Exit in column D price

  Formula (and outcome) in column E

  If the column will B always contained 'Buy' or 'Sell', it works. It is default to a calculation of 'sell' if sale or has been specified.

  E2: = IF (B = "Buy", D - C, C - D)

  If you want to delay the calculation until the amounts entered in C and D, use this version:

  E2: = IF (OR (LEN (C) < 1, LEN (D) < 1,"", IF (B = "Buy", D - C, C - D) ")

  If you want to delay the calculation until all three ducks are on a line (B contains buy or sell, C and D contain both data), use this version:

  E2: = IF (OR (LEN (C) < 1, LEN (D) < 1,"", IF (B = "Buy", D - C, IF(B="Sell",C-D,) "" ")))

  Third version used in this table.

  

  Kind regards
