Question

Total records in table are 10.

Select count(ID) from table1 where col1 = 1 (Result is 8)
Select count(ID) from table1 where col1 = 0 (Result is 2)

So its a same table but count is based on different condition. How am i gonna get two results (counts) using one select statement?

Also Performance is a big concern here.

PS: I am using Stored procedure…

EDIT:
I wanna clear the above query is just a part of a big SP logic (for me at least). Since i got these following answers, it gave another idea to achieve it in different way. My above question is a bit changed now…..Please help here? Its a same col (bool type) with true or false state.

Answer 1

Use CASE:

SELECT
    SUM(CASE col1 WHEN 1 THEN 1 ELSE 0 END) AS Count1,
    SUM(CASE col1 WHEN 0 THEN 1 ELSE 0 END) AS Count0
FROM table1
