MySQL select where column is not empty

Question

In MySQL, can I select columns only where something exists?

For example, I have the following query:

select phone, phone2
from jewishyellow.users
wh         


        

Answer 1

In my case I had a varchar column, both the methods of IS NOT NULL & != '' didn't work, but the following worked for me. Just putting this out here.

SELECT * FROM `db_name` WHERE `column_name` LIKE '%*%'
