Ich habe folgende Aussage:
select DATE(recieved_on) as Day, round (count(*) / 24) AS 'average'
from message
where facility in ('FACID')
AND received on BETWEEN '2022-05-29 00:00:00' AND '2022-06-04 23:59:59'
GROUP BY DATE(received on);
Es liefert die folgende Ergebnismenge:
| Tag | Durchschnitt |
|---|---|
| Datum | Wert |
| Datum | Wert |
| Datum | Wert |
| Datum | Wert |
| Datum | Wert |
| Datum | Wert |
| Datum | Wert |
Wie zeige ich statt aller 7 Werte nur den niedrigsten Wert im Ergebnissatz an?

您只需使用 order by 和 limit 即可：
select DATE(recieved_on) as Day, round (count(*) / 24) AS 'average' from message where facility in ('FACID') AND received on BETWEEN '2022-05-29 00:00:00' AND '2022-06-04 23:59:59' GROUP BY DATE(received on) order by average limit 1
