Any clever SQL people out there? Given the raw data on the left, (a table of test results) how do I write a SQL query to give me the results on the right, (the results grouped by date as well as grouped by result)?

something like this or similar (untested)?: SELECT `date`, SUM(IF(success, 1, 0)) AS `success`, SUM(IF(success, 0, 1)) AS `fail` FROM t GROUP BY `date`

you win! That's brilliant, I didn't even think about using an `IF`!

😎 did you try it already? it was off the top of my head …
