SQL count specific value over multiple columns and rows

Question

I feel as if this should be quite easy, but can\'t seem to find a solution. Suppose I have the following table:

|--------||---||---||---||---||---||---||---|         


        

Answer 1

For reasons of efficiency I don't recommend actually using this approach; but for learning purposes here's another way you could have broken down the problem along the lines of the way you were thinking about it.

select sum(c) as total_ones
from
    (
    select count(*) c from table where q1 = 1 union all
    select count(*)   from table where q2 = 1 union all
    select count(*)   from table where q3 = 1 union all
    select count(*)   from table where q4 = 1 union all
    select count(*)   from table where q5 = 1 union all
    select count(*)   from table where q6 = 1 union all
    select count(*)   from table where q7 = 1
    ) t
