Multiple COUNT() for multiple conditions in one query (MySQL)

Question

I have these queries :

SELECT COUNT(*) FROM t_table WHERE color = \'YELLOW\';
SELECT COUNT(*) FROM t_table WHERE color = \'BLUE\';
SELECT COUNT(*) FROM t_table W         


        

Answer 1

You can do this using subquery.

SELECT(
    SELECT COUNT(*) FROM t_table WHERE color = 'YELLOW',
    SELECT COUNT(*) FROM t_table WHERE color = 'BLUE',
    SELECT COUNT(*) FROM t_table WHERE color = 'RED'
);
