Question

In meinem Anwendungsfall, ich brauche so etwas zu tun,

INSERT INTO TABLE test 
    select 
     count(*) where recordedValue < 0, 
     count(*) where recordedValue > 0 and recordedValue < 10, 
     count(*) where recordedValue > 10 and recordedValue < 20 
    from sample 

Ist es möglich, wie dies zu tun?

INSERT INTO TABLE test 
select count(col1), count(col2), count(col3) From (

CASE WHEN recordedValue < 0 THEN recordedValue END as col1, 
CASE WHEN recordedValue > 0 AND recordedValue < 10 THEN recordedValue END as col2, 
CASE WHEN recordedValue > 10 AND recordedValue < 20 THEN recordedValue END as col3
