Answer 1

Try this if you can have many equal names in your table (you didn’t specify what was the primary key):

select name, sum(
    if (sub1='poor', 1, 0) +
    if (sub2='poor', 1, 0) +
    if (sub3='poor', 1, 0)
) as total from Data
group by name;

Here is an example

Or this if you don’t have repeated names in your table:

select name,
    if (sub1='poor', 1, 0) +
    if (sub2='poor', 1, 0) +
    if (sub3='poor', 1, 0)
as total from Data

Here is an example

Let me know if this works.
