Using a Query or Stored Procedure to Report on the differences between two tables - sql

Question

I have created the following two tables:
Table1:
CREATE TABLE employees
(
PersonID NUMBER(10) NOT NULL,
LastName varchar(255) NOT NULL,
FirstName varchar(255) NOT NULL,
JobRole varchar(255) NOT NULL,
Location varchar(255) NOT NULL,
CONSTRAINT pk_employee PRIMARY KEY (personid) USING INDEX
);
Table 2:
CREATE TABLE DBAteam
(
PersonID NUMBER(10) NOT NULL,
LastName varchar(255) NOT NULL,
FirstName varchar(255) NOT NULL,
JobRole varchar(255) NOT NULL,
Location varchar(255) NOT NULL,
CONSTRAINT pk_dbateam PRIMARY KEY (personid) USING INDEX
);
The following is the trigger and stored procedure I'm using to populate the two tables:
Trigger:
CREATE OR REPLACE TRIGGER trg_trigger_test AFTER INSERT ON employees FOR EACH ROW
BEGIN
p_procedure_test(:NEW.personid, :NEW.lastname, :NEW.firstname, :NEW.jobrole, :NEW.location);
END trg_trigger_test;
/
Stored procedure:
CREATE OR REPLACE PROCEDURE p_procedure_test
(
i_personid IN employees.personid%TYPE,
i_lastname IN employees.lastname%TYPE,
i_firstname IN employees.firstname%TYPE,
i_jobrole IN employees.jobrole%TYPE,
i_location IN employees.location%TYPE
) AS
--
BEGIN
--
INSERT INTO dbateam
(
personid,
lastname,
firstname,
jobrole,
location
)
VALUES
(
i_personid,
i_lastname,
i_firstname,
i_jobrole,
i_location);
--
END p_procedure_test;
/
I need to find a way in which I can create a stored procedure or query to show me the differences between the two tables
Any help would be greatly appreciated, I've been struggling with this.

In Oracle :
SELECT * FROM table1
MINUS
SELECT * FROM table2
OR
SELECT *
FROM table1 t1
WHERE NOT EXISTS( SELECT 1
FROM table2 t2
WHERE t1.some_key = t2.some_key )
In Mysql:
SELECT * FROM table1
WHERE ID NOT IN (SELECT ID FROM table2 )
UNION
SELECT * FROM table2
WHERE ID NOT IN (SELECT ID FROM table1 )
In SQL SERVER
select * from table1
except
select * from table2
