I am not sure how to ask this correctly, but here it is:
table1
id | email
---------------------------
1 test@test.com
---------------------------
2 random@test.com
---------------------------
3 magic@test.com
---------------------------
4 example@test.com
---------------------------
5 noreply@test.com
---------------------------
6 admin@test.com
---------------------------
7 editor@test.com
table2
id | email_two
---------------------------
7 test@test.com
---------------------------
10 random@test.com
---------------------------
33 magic@test.com
---------------------------
99 example@test.com
---------------------------
109 master@test.com
---------------------------
299 blaster@test.com
Question:
How to correctly join two tables, and get not matching results by email? For example, what i need to get from both tables is:
noreply@test.com
admin@test.com
editor@test.com
master@test.com
blaster@test.com
because other emails matching each other.
Code
SELECT email_two FROM table2 b WHERE NOT EXISTS (SELECT * FROM table1 a WHERE a.email = b.email_two
This code returns only missing ones from table2, but i cant find a correct way to return missing results from two tables in one query.
Thanks for any answers.
