Not Like in SQL not working

Question

Trying to use not like in the following sql:
select *
from respondents
where sample_id = 00000001
and email not like '%cccp.org%';
Right now, I'm getting back 51 rows, but 1/2 of the rows have the wrong domain in the email fields, and I need to filter all of the wrong ones, except cccp.org.
There was a thread,
NOT LIKE
And I tried that, but not getting the correct results.
thanks

Answer 1

Given a simple table like:
SQL> SELECT * FROM t;
EMAIL
[email protected]
[email protected]
[email protected]
[email protected]
[email protected]
[email protected] WHERE email NOT LIKE '%cccp.org%' will return:
SQL> SELECT email FROM t
  2  WHERE email NOT LIKE '%cccp.org%';
EMAIL
[email protected]
[email protected]
[email protected] is exactly what you asked for. However, this statement "1/2 of them have the wrong email domain, like .edu and .com email domains" seems to contradict the predicate. Do you really want something more like:
SQL> SELECT email FROM t
  2  WHERE email LIKE '%cccp.org%';
EMAIL
[email protected]
[email protected]
[email protected]
