I am migrating Oracle database into PostgreSQL using Ora2PG tool.
So, I am facing one issue with trigger after generating script output of Oracle database.
CREATE OR REPLACE TRIGGER UPDATE_JOB_HISTORY
AFTER UPDATE OF JOB_ID, DEPARTMENT_ID ON EMPLOYEES
add_job_history(:old.employee_id, :old.hire_date, sysdate,
:old.job_id, :old.department_id);
The script generated by Ora2PG tool.
DROP TRIGGER IF EXISTS update_job_history ON employees CASCADE;
CREATE OR REPLACE FUNCTION trigger_fct_update_job_history() RETURNS trigger AS $BODY$
add_job_history(OLD.employee_id, OLD.hire_date, LOCALTIMESTAMP,
OLD.job_id, OLD.department_id);
CREATE TRIGGER update_job_history
AFTER UPDATE ON employees FOR EACH ROW
EXECUTE PROCEDURE trigger_fct_update_job_history();
when I try to run the above-generated script it will show below error.
ERROR: syntax error at or near "add_job_history"
LINE 4: add_job_history(OLD.employee_id, OLD.hire_date, LOCALTIMES...
NOTICE: relation "employees" does not exist, skipping
Please Suggest or help to resolve it.
When you call a function inside PlSQL code and don’t care about returned value, then you do: PERFORM function_name(…).
Otherwise you do: SELECT function_name(…) INTO your_variable;
So:
DROP TRIGGER IF EXISTS update_job_history ON employees CASCADE;
CREATE OR REPLACE FUNCTION trigger_fct_update_job_history() RETURNS trigger AS $BODY$
BEGIN
PERFORM add_job_history(OLD.employee_id, OLD.hire_date, LOCALTIMESTAMP,
OLD.job_id, OLD.department_id);
RETURN NEW;
END
$BODY$
LANGUAGE 'plpgsql';

P.S. Also you are missing semicolon (END;):
DROP TRIGGER IF EXISTS update_job_history ON employees CASCADE;
CREATE OR REPLACE FUNCTION trigger_fct_update_job_history() RETURNS trigger AS $BODY$
BEGIN
PERFORM add_job_history(OLD.employee_id, OLD.hire_date, LOCALTIMESTAMP,
OLD.job_id, OLD.department_id);
RETURN NEW;
END;
$BODY$
LANGUAGE 'plpgsql';
