@ -53,6 +53,14 @@ Macros:
- $__unixEpochFilter(column) -> column >= 1492750877 AND column <= 1492750877
- $__timeGroup(column, '5m'[, fillvalue]) -&gt; CAST(ROUND(DATEDIFF(second, '1970-01-01', column)/300.0, 0) as bigint)*300. Providing a <i>fillValue</i> of <i>NULL</i> or floating value will automatically fill empty series in timerange with that value.
Example of group by and order by with $__timeGroup:
SELECT
$__timeGroup(date_time_col, '1h') AS time,
sum(value) as value
FROM yourtable
GROUP BY $__timeGroup(date_time_col, '1h')
ORDER BY 1
Or build your own conditionals using these macros which just return the values:
- $__timeFrom() -&gt; DATEADD(second, 1492750877, '1970-01-01')
- $__timeTo() -&gt; DATEADD(second, 1492750877, '1970-01-01')
