Question

I currently am returning a table that looks like this:

Country  Result
------   -----
Japan    sunk
Japan    sunk
USA      ok
USA      ok

with country and result being the column names

Id like to know how many times japan and sunken show up? So the resulting query I am trying to achieve is:

country      numSunk
-------      ------
Japan        2
USA          0

I’ve tried grouping or doing a where result=”sunk” but I keep getting errors. Any thoughts? Thanks.

Answer 1

This should work:

SELECT country, COUNT(*) AS sunk
FROM table
WHERE result = "sunk"
GROUP BY country

Edit: if you want 0-rows then you can do:

SELECT country, SUM(IF(result = "sunk", 1, 0)) AS sunk
FROM table
GROUP BY country
