Answer 1

I just checked it in MySQL 5.7 and am really surprised how no one offered a simple answer: NATURAL JOIN

When the tables or (select outcome) have IDENTICAL columns, you can use NATURAL JOIN as a way to find intersection:

For example:

table1:

id, name, jobid

'1', 'John', '1'

'2', 'Jack', '3'

'3', 'Adam', '2'

'4', 'Bill', '6'

table2:

id, name, jobid

'1', 'John', '1'

'2', 'Jack', '3'

'3', 'Adam', '2'

'4', 'Bill', '5'

'5', 'Max', '6'

And here is the query:

SELECT * FROM table1 NATURAL JOIN table2;

Query Result: id, name, jobid

'1', 'John', '1'

'2', 'Jack', '3'

'3', 'Adam', '2'
