Question

I have a table and I need calculate two aggregate functions with different conditions in one statement. How can I do this?

Pseudocode below:

SELECT count(CoumntA) *< 0*, count(CoumntA) * > 0*
FROM dbo.TableA

Answer 1

This is the same idea as tombom’s answer, but with SQL Server syntax:

SELECT
    SUM(CASE WHEN CoumntA < 0 THEN 1 ELSE 0 END) AS LessThanZero,
    SUM(CASE WHEN CoumntA > 0 THEN 1 ELSE 0 END) AS GreaterThanZero
FROM TableA
