How can I do boolean logic on two columns in MySQL?

Question

I want to do a select in MySql that combines several columns... something like this pseudocode:

SELECT payment1_paid AND payment2_paid AS paid_in_full 
FROM          


        

Answer 1

Ok, for logical and you can do

Select (payment1_paid && payment2_paid) as paid_in_full 
from denormalized_payments 
where payment1_type = 'check';

As seen here.
