Question

This is the sequel to this question.

I would like to combine three columns into one on a MySql select. The first two columns are boolean and the third is a string, which is sometimes null. This causes strange results:

Select *, (payment1_paid && ((payment2_paid || payment2_type ='none'))) as paid_in_full from payments  

Note: payment1_paid is boolean, payment2_paid is boolean, payment2_type is varchar.

Note: Please ignore how ridiculous the structure of this table is. Behind every piece of bad code there is a long explanation 🙂

Edit: Null is not interesting to me for the varchar value. I only want to know if it’s really ‘none.’

Thanks in advance for your help!

Answer 1

If null is not interesting then for you then:

Select *,        (payment1_paid && ((payment2_paid || (payment_type IS NOT NULL && payment_type='none')))           as paid_in_full  from payments 

Good luck!
