count first value, second value or both

Question

I need to do a count, if the first or the second value is true, it should be one, and if both are correct, the value should be two:

 select count(*) from table1 where (cond1 or cond2)

it should be something like this, but I cant get it.

How can I do it?

Thank you in advance

Answer 1

SELECT SUM(cond1) + SUM(cond2) FROM table1 WHERE cond1 OR cond2
