MySQL: filling empty fields with zeroes when using GROUP BY
- by SaltLake
I've got MySQL table
CREATE TABLE cms_webstat (
ID int NOT NULL auto_increment PRIMARY KEY,
TIMESTAMP_X timestamp DEFAULT CURRENT_TIMESTAMP,
# ... some other fields ...
)
which contains statistics about site visitors.
For getting visits per hour I use
SELECT
hour(TIMESTAMP_X) as HOUR
, count(*) AS HOUR_STAT
FROM cms_webstat…
