How to get values for same column name from two different tables in SQL?

column name is emp_id loacated in these two tables: company,employee.

Answer 1

If you want data in seperate columns from two tables then try :

SELECT c.emp_id, emp.emp_id 
FROM company c
INNER JOIN employee emp on c.company_id = emp.company_id 

If you want to merge both columns data then use this :

SELECT emp_id FROM company
UNION
SELECT emp_id FROM employee
