You can use combination of substr , instr and substring_index :

select ename,
    email,
    substring_index(
        substr(
            email, instr(email, '@') + 1
        ), '.', 1
    ) as email_domain
from emp77

Or using just substring_index twice, as suggested by @spencer7593 in the comments below:

select ename,
    email,
    substring_index(
        substring_index(email, '@', - 1)
        , '.', 1
    ) as email_domain
from emp77
