Question

Is there a way to write a mysql select statement to run a count for a particular 1 field only, if greater than zero and equal to zero.

I could write 2 statements to achieve this but is it possible to do it in a single statement.

Answer 1

Something like this perhaps:

SELECT SUM(CASE WHEN x > 0 THEN 1 ELSE 0 END) as GreatherThanZero
    , SUM(CASE WHEN x = 0 THEN 1 ELSE 0 END) as EqualZero
FROM table
WHERE x >= 0
