Question

Imagine this db structure:

`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`correct` tinyint(1) NOT NULL DEFAULT '0'

I want to get the count of all entries with correct = 1, and the count of all entries with correct = 0, in one query.

How do I do this?

Answer 1

Using GROUP BY should solve the problem:

SELECT correct, COUNT(*) FROM table GROUP BY correct;
