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

SELECT phone, phone2 
FROM jewishyellow.users 
WHERE phone like '813%' and (phone2 <> "");

May need some tweakage depending on what your default value is. If you allowed Null fill, then you can do "Not NULL" instead, which is obviously better.
