(Ensure that you position the cursor on the data row that you want to copy before you insert the new row.) The only new information is the effective date, which is set by default to the system date (usually today's date).

The solution to mutating problem is explained at : Work around for mutating problem in Oracle Triggers. create or replace trigger trg_log_job_change after update of job_id on employees for each row declare v_enddate date; v_startdate date; begin -- find out whether the employee has any row in job_history table select max(end_date) into v_enddate from job_history where employee_id = :old.employee_id; if v_enddate is null then v_startdate := :old.hire_date; else v_startdate := v_enddate 1; end if; insert into job_history values (:old.employee_id, v_startdate, sysdate, :old.job_id, :old.department_id); end; Note: Before testing the above trigger, you need to disable UPDATE_JOB_HISTORY trigger, which is already present in HR account, as it does the same.

And I need to create 1 trigger that checks if the department number of the updated worker, the total salary between all the workers of that department doesn't exceeds 10000, but I don't know how to do it really... CONTROLSALARIDEPT", line 14 ORA-04088: error during execution of trigger 'SPECIAL.

A: This is a huge topic, please refer to the documentation here: In short: this is a special kind of a trigger that makes psiible to combine four types of separate triggers: The optional declarative part (the first part) declares variables and subprograms that timing-point sections can use.You can work only with current and future job data on the Current Job pages. Or you can plan ahead and set up tables and data before they take effect.The Job Data and Current Job components are made up of the same pages as the Add Employment Instance, Add Contingent Worker Instance, and Add a POI (person of interest) Relationship components. The system also uses effective dates to compare pages and tables to ensure that the prompt tables that you see list only data that is valid as of the effective date of the current page.CREATE OR REPLACE TRIGGER compound_trigger_name FOR INSERT OR UPDATE OF salary ON treballa COMPOUND TRIGGER TYPE Departments_t IS TABLE OF treballa.department%TYPE INDEX BY varchar2(100); Departments Departments_t; BEFORE EACH ROW IS BEGIN -- collect updated or inserted departments Departments( :new.department ) := :new.department; END BEFORE EACH ROW; AFTER STATEMENT IS sum_sal NUMBER; BEGIN -- for each updated department check the restriction FOR dept IN Departments. The session that issued the triggering statement cannot query or modify a mutating table.
