Question

Suppose I have the following queries.

SELECT count(*) FROM info WHERE info = 'a' and uid = 1
SELECT count(*) FROM info WHERE info = 'b' and uid = 1
SELECT count(*) FROM info WHERE info = 'c' and uid = 1;

Instead of writing 3 queries is there any way so that I can get all these details in a single query?

Answer 1

SELECT info, count(*) as info_cnt 
FROM T
WHERE uid = 1 and info IN ('a', 'b','c')
GROUP BY info
