MySQL Query

Richard Korts
Last Modified: 2016-02-01
I have this query on a MySQL table

SELECT * from cvisitor where SUBSTRING(last_time,1,10) >= '2016-01-27' and SUBSTRING(last_time,1,10) <= '2016-01-28' and email not like '%@lakos.com' order by last_time

There are a number of rows where the email IS like @lakos.com. They are not excluded.

If I do the following, it works.

SELECT * from cvisitor where email not like '%@lakos.com'

Why does not the first work?  Do I need parens around date comparisons?
