Question

I’m new to MySQL so I really need some help with an issue I’m facing:
I have 7 tables in same database with some datas from tests:
The 7 tables have different columns but they all have these columns:

• name.
• second_name.
• status.

In status are added current status of each student (accepted or rejected) and I want to display using select the name, second_name from the 7 tables where status = accepted.

I managed to display from 1 table

SELECT name, second_name FROM test1 WHERE status="accepted";

But I can not figure out how to display from all 7.
It will be a real help for me if somebody could give me a hint.

Answer 1

If you do not mind duplicate student names with multiple accepted tests, you can try doing it with UNION ALL:

(SELECT name, second_name FROM test1 WHERE status='accepted')
UNION ALL
(SELECT name, second_name FROM test2 WHERE status='accepted')
UNION ALL
(SELECT name, second_name FROM test3 WHERE status='accepted')
-- ...and so on
